Well, it’s 3/14/2017, time for the 7th annual Vi Hart Pi Day video:
This came after months of kinda obsessing over diagrams and Venn diagrams in particular. It started with reading Lakoff and Johnson’s “Philosophy in the Flesh” and deciding to try making embodied container schema of various sorts in virtual space:
During the research for the writeup I did on that project, I read John Venn’s original 1880 paper, and was inspired to try some embodied Venn diagrams, eventually creating an entire Venn Diagram House:
The writeup on the Venn Diagram House has more on the motivation and takeaways from that. Relevant for this post is that after creating the ovenn with venn burners, it seemed obvious to put a venn pie in there. Making one for real didn’t seem too interesting until Pi day started looming near, and I do have a tradition to keep, so that’s how that happened.
But first, I continued making virtual Venn stuff, including an entire interactive Venn Diagram Museum of Geometry, Topology, and Algebra. When working on the geometry section, doing an exhibit on the Reuleaux triangle seemed obvious because they’re so much fun, and as long as I’m doing intersections might as well do a bit on the Vesica Piscis, so that was in my head when I started working on the Pi day video.
The above virtual projects are public in Anyland for Vive, if you’ve got one. And if you’re interested in other virtual projects like this or want updates on these projects when they happen, check out elevr.com.
On the virtue of good habits, rather than anger and dramatic causes, for sustaining democracy.
If you wait for big motivating problems before acting, you’ll be comparatively ineffective both because of waiting too long and your own lack of practice engaging with politics, which makes you susceptible to those who would prey on your anger and disappointment.

Great musicians spend years learning to play, great writers spend years learning to read and write and tell stories. We love the myth of immediate success out of nowhere but the truth is that stuff takes work, stuff takes practice, and anyone willing to put in the work can gain some level of accomplishment.
This is advice that I hope you’ve heard before, but it applies to more than just personal success.
There are forces in the world that would like you to believe you are powerless, that your actions don’t matter. That your votes, your donations, your calls, your protests, don’t matter. That truth doesn’t matter. That you can trust no one, not even yourself, that all choices are equally bad, the system is broken, everyone is corrupt, you can’t change anything, there are forces in the world that are actively trying to manipulate you into giving up your power.
But you are powerful, it just might take a little bit more time and effort than you were hoping for. Let no one convince you that your opportunity to use your power comes only once every four years, and only if the right candidates are presented to you.
There are those who would love to force Trump voters, many of whom were reluctant to vote for him, to become Trump supporters, pushed to the extreme by their constantly having to defend their own choice and by extension Trump himself, even as they start to realize he’s not going to keep his promises to them. I know there are those who voted for Trump and are already acting on their concerns about him, because voting for someone doesn’t have to mean supporting everything they do until the next election. You can vote for a flawed candidate and then work on the flaws.
I know people whose support for Bernie Sanders was both their first real political action, and their last. There are forces who would convince you not just that his loss was unfair but that the answer to this unfairness is to withhold your participation, to somehow punish the system by standing idly by, watching and criticizing your own democracy for making mistakes it could have avoided with your help, could still avoid with your help. What do you think you’re left with when no one participates in a democracy?
Question the motives of those whose cynicism promotes only inaction, those whose moral posturing demands only inaction, those who would tell you the way towards positive change is to do nothing. Be wary of arguments with self-selected strangers who engage with you solely for the purpose of disagreeing with you and telling you to stop. There are plenty of good faith discussions to be had with those around you, your neighbors your friends your family your community, who you might disagree with on some things or have different knowledge and experience but you can find common ground and be accepting of each other’s humanity and work together. Spend your time with those people, not with those who would target you as an opponent to be beaten.
Remember there is such a thing as truth and reality. Remember that in the US we have the constitution, a foundational document that gives us common ground. It is not partisan to denounce unconstitutional actions. Everyone, including the electoral college, has plenty of good reason to reject Trump given his disregard for the constitution, his conflicts of interest and the conflicts of the people he’s choosing for his team, he never had strong Republican support, doesn’t have popular support, and is on track to be very destructive if people don’t step up and do more than just criticize each other.
By the way, the electoral college doesn’t vote until December 19th, and technically they can vote for whoever they want. And I mean anyone; a couple electors this year say they’re voting for Mitt Romney. Electors are chosen by the state’s winning party, and it’s possible that enough electors will stick to their morals and deny Trump a majority, in which case the vote would go to the house of representatives meaning your congressperson might be deciding this election. Maybe not, but there have been elections where entire states worth of electoral voters got together and voted for someone else. So there’s something you could practice engaging with politics about, whether it’s because you do want the electoral college to vote for someone else or don’t want them to or maybe you don’t like the idea of the electoral college altogether. If you don’t like the system, our system was built to be able to change itself, but only if you participate in it, and for those who work better under a deadline, it’s not so long before the December 19th electoral vote.
If you don’t think your actions can immediately cause the change you want, that’s fine, not all actions have immediate results, or obvious results. But participate anyway. Politicians can safely ignore those who don’t participate or who participate only once and then get discouraged. And if enough people don’t participate, they can ignore all of us, and that is how democracy fails. There are other powers in the world who would like to see us fail in exactly that way. But participating in politics gets easier with practice, and it’s something that everyone can learn how to do.
Step 1: Make a list. Paper, digital, whatever, give it a fancy title, this is the list that you can then populate with other actions you might like to take, and the goal is to do one or more of these actions… every Tuesday during lunch, for example, just for 5 or 10 minutes, during Action Time. It’s easy when it’s a habit, and if you can find a buddy to team up with for Action Time, that’s a good step 2.
The great thing about having a list and a time to act on it is that instead of constantly worrying about the state of the world or stressing over the news while you’re supposed to be doing other things, you can just put your worry on your list and get back to what you’re doing until action time.
Here’s some things on my list:
1. Call my Congresswoman to congratulate her on being elected House Minority Leader. I’ve called her before about other things but this is partly because it’s easy practice making congress calls and partly getting another call on the books so that congress knows that this citizen is paying attention. I will probably reach a very nice intern who will be happy to hear the support and to pass along my comments and if they have time I’ll ask them if there’s anything else that should be on my radar and they will be thrilled to tell me all about important political happenings that don’t reach tend to reach the headlines and we’ll both end the conversation happier and better informed.
2. Email my friends in Oklahoma and Texas and ask if they would make a call to their local politicians about women’s rights, this is on the list because I saw some scary stuff in the news that I wanna do more than just be mad about.
3. Look up my local party headquarters and events, I’ve been meaning to check out what’s up around here and maybe there’s an event I’d be interested in, maybe not, I dunno.
4. Something about Education? I’m not sure what yet but I do tend to get dragged into education policy discussions and I’d like to help counter the damage DeVos could do to public education.
5. Call state governor and local politicians expressing a hope that our supermajority of Democrats will play nice with our state Republicans rather than getting infected by Trump drama partisanship.
6. Subscribe to a local news source. Because reading and supporting real journalism that answers to subscribers, not advertisers or clicks, is essential for holding politicians accountable, fighting corruption, and staying informed, and I’m not paying for anything local enough to care about my local politicians right now.
What else? If I lived in a Red state, I’d be calling my state’s Republican party to ask that our Republican electors vote for anyone but Trump. If I lived in Louisiana I’d be trying to get everyone around me involved in the current senate race. If I lived in the UK, I’d be making calls regarding the Brexit negotiations, if I lived in France or Germany or any other democracy I’d be paying attention and taking action while I still can. You can call with friends, letters are good too, you can gather a group and help each other, you can have a letter writing party, you can call on speakerphone with a friend who’s better at phone calls than you are, with practice it’s just as easy to complain to your representative as it is to complain to your friends on social media though you can keep doing that too as long as you’re not doing that exclusively.
It’s good to have a long list you can work on even just for five minutes a week, avoiding the drama and pressure of putting all your hopes in one giant push for one person, one big rallying cry for the most dramatic political thing ever. Changing the world doesn’t require stress and anger and all-encompasing negative emotions. It’s a skill that takes regular practice just like everything else in life so make a list, schedule in some Action Time, and relax. We got this.
The internet is full of information for wherever you are and whatever you care about. Also talk in person to friends, family, and people in your community, to learn what they know and help each other take action!
On election night 2016 I had flashbacks to the 2000 election, staying awake late into the evening glued to the television hoping that Florida would come through for, well, in 2000 I was a kid and a total Democrat just like my parents. And I remember how deeply unfair it felt when Al Gore won the popular vote but lost the election to George W. Bush.
Two things about that election stuck with me, that ended up transforming how I think about politics. The first was how close it was. Even back then I had a good enough intuition for statistics to know that if presidential elections consistently come up so close, within a few percentage points almost every time, that’s not random. The second strange thing was this whole idea of red states, blue states, and swing states. A lot of people focus on the swing states but what I found much more mathematically compelling is that there are red states and blue states. Why are there states that don’t change their mind?
The feelings from that election night followed me through the aftermath of 9/11 and the wars I didn’t want and all the way to the polls once I was 18, but in the mean time it was taken as a given in my entire liberal bubble that obviously Bush is stupid and Republicans are stupid and I went along with this way of thinking until those old questions started to dig at me. Why aren’t the Democrats, who are so obviously correct, winning by a huge margin? Why are there Red states at all? The standard answer in my circles seemed to be that, well, if Bush is stupid and Republicans vote for him it’s because they’re stupid, and if Republicans are stupid and half the country is Republican, then it must be that half the country is stupid, look at us the smartest teenagers ever, struggling to make our way through the land of the stupid.
The aura of logical language lends the voice of authority but it doesn’t make something true in real life. I learned that red states are red because they have more rural areas, and blue states are blue because they have bigger cities. I learned that whether you’re Democrat or Republican can be pretty accurately predicted by where you’re born, and no one chooses where to be born. I had to consider that if I were born in a different place with a different family I would be an uncompromising Republican who makes fun of stupid liberals and believes all the anti-liberal stereotypes, and I realized there’s also plenty of awful people who are Democrats just because of their circumstances.
I learned why elections are so close, that if one side leads by a lot, they can put fewer resources into campaigning, while the losing party shifts their platform to appeal to more voters, meaning that Democrats and Republicans are not two fundamentally different types of people with fundamentally different ideologies, but moving targets in a self-balancing system. I had to entertain the premise that maybe Republicans and Democrats are equally intelligent people doing the best they can with what they know, and as I got older and my world grew, I’ve met many very smart and wonderful Republicans who have led me to believe that, as usual, my younger self was too quick to judge.
That is the divide I want to heal. The divide that made my teenage self mock Republicans for their big gas-guzzling trucks while I enjoyed the invisible urban infrastructure that paved my roads, picked up my garbage, and delivered the gas I used to heat my home through hidden pipes. I want to heal the divide that makes some liberals not just mock but actually fear people who find personal and cultural value in gun ownership, the divide that makes us forget how easy it is to demand we all get rid of something that only other people value. I want to heal the divide that leads many nonreligious city dwellers to fundamentally misunderstand the social infrastructure roles of the church in rural communities, caring for the sick and the poor in places far from the offices of government-funded social programs. The shared infrastructure of cities makes it easier, more efficient, to improve quality of life with less money, to adapt to changes in the world, to recover economically.
That’s the usual divide, but with Trump I think there’s a different story, and it’s not one I’ve seen anyone else telling.
You see, a lot of people were surprised by Trump’s victory, and this surprise has led to a lot of speculation regarding the polls and where they went wrong. Which they weren’t really that wrong because Hillary won the popular vote by a large margin so it’s not like there’s some mysterious chunk of Trump supporters we didn’t know about, but anyway. The difference between the polls and the outcome led to this obsession with pointing at different bits of the polls to try and explain why Trump won. It’s the standard fallacy of focusing on what’s measurable because that’s what is easy and incontrovertible. It’s evidence, it’s proof, and anyone with basic math skills can compare numbers in the completely logical agreed-upon form, and let’s combine that with my other favorite intellectual mistake: the one where you get what you measure. If you measure race, you get race, if you measure gender and sexuality, you get gender and sexuality. Media has been taken over with arguing about these things because it’s easy to pseudo-rationally argue about what number is bigger than what other number. The media is centering the conversation around identity politics because that’s what the data is, but it’s not what the data shows.
Like, Trump didn’t win because of lower black turnout, though voter suppression worked pretty good there. Trump won and also we measured black voter turnout. We measured lots of things.
So I took a fresh look at the data. Lots of data, in larger contexts, and weeks later I’ve finally come to a conclusion.
I was wrong. It’s not really about liberal vs conservative, city vs country, white vs multicultural, not this time. It’s really about old and young. Not vs, and not necessarily as individuals but also as communities and as a culture, ok here we go:
First the shallow data part. Edison Research, which does the US election exit polls, shows that over-45s voted Trump while under-45s voted Hillary, and other polls show other breakdowns, over-50s voting for Trump, the trend of all the polls is that the older you get the more you’re a Trump voter, while Hillary was strongly favored among younger voters. 18-29 most strongly, and 30-45 also. And voter turnout in those age groups looks pretty normal, though if younger voters turned out like older voters did Hillary would’ve won in a landslide, meanwhile Baby Boomers are getting older, lifespans increase, and the older you are the more you turn out to vote so this was a good election for appealing to older voters, and older didn’t used to be a Republican thing but Obama’s appeal to young voters set the stage to take the G out of the GOP this year. But it’s not the pure demographics that popped out to me, but the correlations.
Correlations like… that many rural areas are increasing in average age as young people seek opportunities in the city and the older population keeps getting older, industry changes, and they’re left without a job they’re trained for, and it’s not like there’s a university in town where they can learn new skills and qualifications. Which means this statistic is related to the economy, though remember people who make less than average voted for Hillary, and how much you make is also correlated with age, so while poor young voters voted for Hillary, Trump’s voters are worrying about retirement and healthcare in a system that is failing them on both counts. Age is correlated with race, and US demographics are getting increasingly diverse which hasn’t really hit the voter pools yet, and also consider religion. I don’t mean diversity of religion, I mean the middle-america sort of religion where the church isn’t just a community but the community, with a cohesiveness that trickles down from older members.
I want to talk about age not because it excuses anything, but because it changes how we should approach this. When people living in different places reject each other’s way of life, that’s something to compromise and come together on. But if it’s really that younger people are looking towards the future while older people want to go back to how things were, that’s a different conversation. Trump didn’t just lose the popular vote, he lost the younger half of America.
America has changed. Younger voters are multicultural, we have a diverse range of identity, we’re adaptable, we’ve had 4 different jobs in multiple industries, we don’t expect job security or abundant natural resources or to have the world our parents had. We adapt, and we care for each other, not just in the USA but around the world, because we are connected, we are informed, we have the world at our fingertips. We worry about how we’re going to deal with the environmental issues that have been handed to us, how we’re going to end the wars that have been handed to us. Everyone wants to leave a better world for their children and it would be natural for older folks to be a little resentful that we find so many flaws with the world they’re handing to us, but this isn’t the story of two Americas, it’s a story of new Americas, about a country that has improved and changed many times over. There’s no sides to fight and win. This is a gap you bridge by being kind to each other, by asking older America not to reject America’s youth and younger America to respect our history and our elders and make sure they are not forgotten in a world of new technology. There’s a difference between the young angry neo-nazi Trump supporters that have been so emboldened by him, so encouraged by his administration, and the voters who are older and disconnected and who I think actually make up his base.
Dark forces in the white house would divide us, Steve Bannon is pretending Trump’s win was about a culture war between nationalists and liberals, pc culture and working-class middle America, rather than a generational difference. The same think pieces the media was writing about millennials years ago are now being rewritten as pieces about liberals, but we’re still the same people and we’re not going away. Legacy media is obsessed with the idea of identity politics while we’re already over it, we’re just trying to understand and respect each other in a changed world. And maybe with all these new changes we did forget to include older people’s struggles. Maybe we fell into the fallacy of valuing the lives of hypothetical future people more than the lives of those already here in our communities.
Older voters didn’t grow up with the idea of climate change, it’s not about liberals being smart and Republicans being science deniers, the numbers tell me it’s about age. Statistics tell us Trump voters are uneducated but remember education levels have increased with time and that’s a good thing, and also maybe we have some work to do in bringing education innovation to people who aren’t in school, and don’t come into contact much with more recently educated people.
Older voters didn’t grow up with the internet. The numbers show that older you get the more time you spend watching television, that’s where information comes from for a lot of people, and legacy media, in their efforts to be fair to the other side and get ratings from their audience are completely missing how pro-Trump they sound to younger demographics, whether they—or Trump—think they’re being pro-Trump or not. Maybe when young people rejected old media and went to the internet, we didn’t think through all the side-effects.
Maybe we can spend some time teaching older folks about climate change and how to sort out hoaxes on the internet, and they can spend some time teaching younger folks about the importance of turning out to vote and how to use telephones to call representatives.
Trump played to people’s fear, not just to general economic anxiety but about retirement and their legacy and their own mortality. Fear of the existential threat posed by imaginary invasions. He knows how to speak to people his age, to white people who grew up during the cold war, and in places where support will trickle down because of community structure.
There’s an important difference between those who fear the unknown and those who hate the known, between those who avoid someone because they don’t want to be hurt and those who engage with someone because they want to see them suffer. The former behavior might not be acceptable, but it’s approachable. You can talk about it.
I don’t make excuses for bigotry but maybe we can change how we approach it for the large share of Trump’s voter base who might be active in opposing it if we give them space to. There’s plenty of older folks who are excited to be challenged and engaged by the young American culture, who are willing to admit they’re wrong when they’re wrong, even if it challenges their authority.
But from what I’ve seen of Trump and Bannon, they enjoy seeing the suffering of those who disagree with them, they seek to punish those who oppose them, and you can’t have a successful dialogue with someone who would like to see you hurt. Democrats won’t work with Trump, but Republicans can’t work with Trump. They could obey him, but they can’t work with him. Whether the white house reflects it or not, there is no future in Trump. The world already changed.
Some of Trump’s voters just want to burn it all down but most of them have shown that they care about the future of our country, they are engaged, they want to work hard, and maybe we can find a direction for that energy that we can agree on, rather than leaving older generations behind. Because we’re going to have this same problem when we’re old and future generations are fluent in technology we can’t imagine, that connects them to information and understanding that we can’t access effectively. Let us learn now how we bridge the gap of age in a world of increasing information technology.
Can we call our older friends and family and tell them our concerns, tell them about the world we see? Can we listen to their stories? Can we remember that our representatives and senators are also mostly older and didn’t grow up with the internet and aren’t reading our twitter feed and give them a call to share our concerns? Can we reach out personally to those who get their information that way? Can we find a way to disagree in our opinions but agree on the facts? Can we ask those who grew up in a different time to support us? Can we ask those who grew up in a different time how we can support them?
I feel mostly hopeful but there’s a certain bittersweetness to it and I can’t help think of my grandma. I lived with my her when my mathematical work started becoming popular, I respected her dictatorial authority in her home and I forgave her the occasional comments that one would call “old fashioned” when said by your own grandma. But I often think about the fact that when she was ill, she made a conscious decision to die rather than leave home. It’s not an uncommon choice. We are defined by the things we value more than ourselves. My grandmother made a home; and as frustrated as I was with her unwillingness to use the internet or accept a broader range of identity, she made me welcome in the home that was worth more to her than her own life.
And so, to the future generations who value the lives of all of us equally, I entreat you to remember that life is to be honored universally but spent individually. Be kind to those who truly define themselves as Americans first, those who would whole-heartedly welcome you into the country they would give their life for. That is a kind of nationalism to be respected, and I think we can find a way to come together in support of America’s new culture while still honoring those who got us here.

Welcome back to Vi Hart Weekly! As you know, every week has a theme, and sometimes when the theme is less obvious people enjoy drawing their own connections and trying to guess it. Spoiler: last week’s theme (or at least the one I intended) was tiny things / scale.
Now on to this week!
1. Improvisation of the Week:
Some piano + voice improvising I did after work on some day I forget. I forget what it sounds like, because getting it out of my brain is what recording and sharing things is all about. Bye piano thing!
I like Audacity for sound recording because it is so very simple. It doesn’t do hidden secret things or try to be smarter than the user. But when recording this I had a problem where occasionally Audacity would insert a bunch of zero values into the samples. All the information is there on either side, just these extra bits create an awful click sound.
I was hoping to be able to quickly search the samples for strings of zeros and remove them, but unfortunately they’re not quite zero, making it a little harder. Just getting rid of strings within a certain range could false positive on soft sections too. Really the thing to do is look for sudden changes in slope that go to/from zero. I managed to get rid of most of the clicks!
2. Vacation of the Week:
I’m feeling good and am later than usual for this weekly because I managed to take three days of vacation!
Says my brain. Really two of those days were the weekend, brain, and those don’t count. Ok, so one day of vacation, says my brain. Except I worked until 2pm before leaving for said vacation, so.
But pretty good, doin’ pretty good on the actually-take-time-off-and-don’t-burn-out thing. I only filmed one video while on vacation and I didn’t even edit it on vacation. Taking time off is important for being able to continue doing work, but it’s easy to look at that time and regret that I got so much less done in the past week than in weeks when I work constantly! A reason not to judge productivity on a weekly basis. Need larger sample sizes to smooth over the zeros.
3. What’s up at eleVR:
We’ve been spending some time lately organizing our many projects and blog posts, and I’m constantly amazed at how much we’ve done. So many experiments forgotten and dug up as we go through old bits of research. Our projects page is awesome.
One of these old experiments we never documented was when we tried making 360 video with just a normal smartphone and a cheap clip-on wide-angle lens, to see how inexpensive simple consumer VR creation could be. So I wrote up a post about that, and cut our old documentation footage into a video (in the post too).
But the big news is that Evelyn Eastmond is officially joining my team! I’m really excited about this because she is exactly the kind of deep-thinking world-aware artist-programmer I love working with, and I’ve been wanting to work with her for a while. So I’m just thrilled that she’s agreed to join. And now she’s in the regular eleVR blog rotation too, so you can check out her posts.
4. Vi Hart Video of the Week:
I posted about this in my previous blog post because videos sometimes get their own posts, but it’s still the Vi Hart video of the week.
Recommended to me by Paula Te in relation to my work on Real Virtual Physics, this is a fun paper that describes a 5-day activity with a group of sixth-grade children where they are encouraged to invent and improve on different ways of representing motion.
It’s interesting to read through the thought processes of the kids as they critique various invented representations, and move towards things resembling traditional representations of motion (distance over time, speed over time, etc). It was also interesting that a big sticking point was how to represent the duration of a stop. Ah zeros, always messing things up.
I think there’s something very important about understanding what kind of thing a representation-of-motion is, and what information it should contain, that can only be gained by working with more than one kind of representation-of-motion (even if some of them aren’t very good). Once one knows what kind of thing it is, then looking at traditional representations makes more sense.
It’s also interesting to read transcripts of bits of students’ discussion, and how critique of peers—who are indeed the world experts in their own invented representation—can motivate deeper thinking than discussion of an existing standard representation (which even the teacher might not know the reason for various choices).
I made a video! Again! It’s just a thing that happens sometimes.
This one is a true story about when I got mad at a taxi driver that skidded through the crosswalk in the rain, and why they were DEFINITELY DOING MATH WRONG.
Part 2 will be out next week, maybe?
Also, obviously I started writing this script a long time ago because it hasn’t rained in ever. But I still think if California focused more of its policies and funding towards higher quality math education, it would make our streets safer.
Transcript:
Today, I was walking across the street and this taxi comes zooming up to the crosswalk at a red light and slams on the brakes and skids across the crosswalk a foot in front of me and I’m like, dude, it’s raining, do you not realize how that affects the derivatives of your position over time, my goodness, I was one foot away from being turned into a pancake by your bad math education.
Now, every driver knows that speed is what happens when you change your position over time (such as the changing position of your car as it approaches the position of the crosswalk) and that acceleration is a change in speed over time (such as, y’know, how even if you change your speed by decelerating as much as your brakes and road conditions allow, you will still be going a positive speed by the time you reach the crosswalk, ). What many drivers don’t seem to know is that these changes are related by mathematical laws. Some drivers are like, you’re here, and then later you’re there? No one can explain this.
And, I can understand that. The idea that anything ever goes anywhere is kind of tricky if you’re Zeno and calculus hasn’t been invented yet. I mean, say you’re 20 meters from the crosswalk. How does one hit pedestrians if before you can get to the crosswalk you have to drive halfway to the crosswalk and then you have to drive halfway between there and the crosswalk and then halfway between there and the crosswalk? and so on. If each of these steps took the same amount of time, then that would be quite an interesting deceleration, you’d never hit anybody like that. But say you drive those first 10 meters in one second, and those next 5 meters in half a second, and the next 2-and-a-half meters in a quarter of a second, it doesn’t matter how many infinite bits of distance you’re adding up, you can break apart those 2 seconds and 20 meters in whatever way you find interesting but 2 seconds later you’ve still gone 20 meters and 2.1 seconds later you’re still trying to ruin my day.
There’s this stereotype about California drivers that whenever it rains, which is rarely enough these days, traffic stops because all the drivers are freaking out like what is this substance all over the ground, we don’t know how to do math to it.
The common wisdom seems to be that when it rains, you should just drive slower. A classic error of calculus, because it’s not really the speed that’s the problem with rain, but how it affects acceleration.
It’s like this: you’re goin’ along at a constant speed, uh, this is time and this is speed and this line is nice and flat so no change in speed is occurring, you’re just driving at 50 miles an hour. But then, oh no, there’s something in front of you, so you slam on the brakes. Now your speed is decreasing, decreasing, until you hit a speed of zero and stop. If you’re at a slower speed to begin with, then this line intersects zero earlier, you can stop faster. So far so obvious.
The slope of this line changes depending on your car and on road conditions: maybe you come to a stop real quickly, or maybe your brakes are bad or the road is icy and you just kinda glide for a while until finally you hit zero. Your car might be able to decelerate real fast when it’s dry, but not so fast when it’s raining, and then even if you start out slower it might take longer to actually stop. You can’t just drive slower, you have to leave more distance between you and the car in front of you, and start braking earlier when you’re coming up on a light, which is why that’s what they tell you in driver’s ed. Whereas if you’ve got lots of room and can decellerate for a long time, you can start at a greater speed even if it takes a while to decelerate to zero. Which is the part they don’t want to tell you in driver’s ed.
Of course, this is graph is kind of misleading because it’s not like the crosswalk is here, this axis shows time, not place. And when we need to stop, we usually don’t care about when to stop so much as where to stop. This graph shows the speed of a taxi that needs to stop at a crosswalk, but let’s overlay the position graph in red, same time axis, different y axis, so we can show where the crosswalk is . Here’s where the Taxi is when I see it coming towards the crosswalk, here’s the crosswalk, 20 meters away. So the driver is going along at a constant speed, that’s this nice linearly increasing distance, realizes it’s a red light and slams the brakes here.
It’s slowing down, and the distance over time starts this nice deceleration curve. Of course, in my case it doesn’t reach the flat zero slope of a stopped car until it’s gone through the crosswalk. Wish it could stop sooner, but once you decide to stop, there’s a max decelleration, you can stop faster if you have better brakes or less momentum or if the ground is dry but there’s always a max slope your speed can drop, which means a max curve your position can take so there we are in the crosswalk.
Accelleration, speed, and position, these things are related so don’t run me over in the rain. Lookin’ at slopes.
But the story doesn’t end there. We’re leaving off with the taxi driver stopped in the crosswalk but what happens next will surprise you. Or, not really so much, but I wanna talk about hover cars? Anyway see you next time for part 2.
Welcome back to Vi Hart Weekly! I am glad you are here!
1. Designer of the week: Otto Zenke
In particular, his miniature rooms, of which there are several in the Greensboro history Museum, which I was at last week. Curator Jon Zachman was kind enough to let me put a spherical camera inside one of these tiny rooms and tell me a little bit about history behind them. It’s a pretty compelling use of spherical video:
2. Geometric space of the week: Hyperbolic Three-Space
This week I finally got around to documenting a project I did with eleVR, Henry Segerman, and Mike Stay, back in 2014. Or at least, I documented a little bit of it. We made hyperbolic virtual reality.
In this video I show an unusual property of an unusual tiling of three-dimensional hyperbolic space. Hyperbolic space gets really big really fast, but not fast enough to fit six cubes around an edge without something very interesting happening at the vertices:
3. Book of the week: The Tiger’s Wife, by Téa Obreht
The Tiger’s Wife is a subtle piece of literature. In some ways it is very small and personal: one young woman recollecting stories surrounding her grandfather, in the days following his death. It only very subtly connects to bigger themes and bigger events, in a way I very much appreciate. It is well-written with evocative imagery, and just the occasional hint of that sort of literary cruelty à la Infinite Jest, if you know what I mean.
4. Pint of the week: Organic Sugar Plum Grape Tomatoes
Tiny tomatoes are, in general, the best food. This is because, being tiny and numerous, a pint of them has more surface area than a pint of larger tomatoes. Sometimes cherry tomatoes are tiny enough. This time, grape tomatoes and the best tomatoes. Because of their size and elongated geometry, they are almost entirely made up of outside.
Because they have so much outside to eat, and that’s where pesticides tend to sit, the organic component is extra important when eating a pint of tiny grape tomatoes.
5. Paper of the week: Assessing student learning of Newton’s laws: The Force and Motion Conceptual Evaluation and the Evaluation of Active Learning Laboratory and Lecture Curricula, by Ronald K. Thornton and David R. Sokoloff
This is related to my work on Real Virtual Physics. It describes the assessments they did with students using tracked physical objects to learn about speed, acceleration, and visualize them as graphs, etc.
My favorite thing about this paper is that when discussing student answers it doesn’t refer to answers as being right or wrong, but instead refers to answers as either aligning with Newtonian physics or not. It mentions some other conceptual frameworks students use to think about motion, and the idea that having a model of physics in your head, even if it’s wrong, is it good sign of student ability to learn. It reminds me of some some of the stuff Papert talks about, that memorizing laws of motion is pointless if one doesn’t know what kind of thing a law of motion is. Papert recommends students get experience with microworlds that have different kinds of laws of motion, before trying to learn what the laws of motion of the actual world are. Of course, Newtonian physics is not our most accurate way of modeling real motion, so I appreciate this paper’s emphasis on teaching students to think in a Newtonian way, rather than teaching them the right answers.
My least favorite thing about this paper is that it is evaluating a curriculum and learning tools at the same time that it is evaluating the evaluation used to evaluate those tools. The results could mean nothing more than that teaching to the test yields higher test scores. They do address this issue by correlating responses to different question types, and it sounds convincing and everything, but it certainly leaves more work to be done.
6. News Introspection of the week: explosion in Chelsea
Whenever a breaking news story is going viral on twitter, I take the opportunity to introspect by asking myself what I want to be true. This kind of awareness is important to limiting the effects of confirmation bias and becoming more able to understand the world as it is.
It’s easy, on twitter, to judge others and get outraged about what they want to be true, but that’s less helpful. Some people want whatever truth supports their politics. Some people like big news because big news is exciting, and our human brains can’t help wanting exciting things sometimes. Me, I’ve learned I like tiny news. Maybe I have enough excitement in my life.
I’ve practiced news-introspecting enough to recognize, when I saw Chelsea trending, that I wanted the explosion to be minor and accidental, that I would be drawn to things that support that wish, and more skeptical of reports that it was an organized terrorist attack that caused serious harm (and more reactive against anyone speculating that might be the case).
It’s looking right now like the truth is somewhere between those things, an intentional act of terror that is not connected to outside groups, and that we are very lucky in how minor the damage was. And I’m aware that now I am happy to stop following the story, while those who are hoping a connection to terrorist groups will be discovered are more likely to keep following, so if evidence in that direction is discovered (even if it’s not certain yet) their beliefs will be confirmed, and then they can stop following too, so we all get what we want. Hooray!
7. Pumpkin Spice of the Week: Pumpkin Spice
Documenting this thing because, well, because:
I feel like everyone else is surrounded by pumpkin spice. Is it real? Or a fantasy, the American dream? I can’t help but want it too.
The last screenshot is from this site that analyzes headlines for clickbaitiness: http://coschedule.com/headline-analyzer
I did that bit because it is my headline art.
Seriously though, pumpkin spice seems to be one of those cultural things that secretly broadcasts some secret group affiliation. Also I would actually like to have some, but it turns out that not all places are forcing pumpkin spice into everything. Instead I have no pumpkin spice but lots of over-analysis.
Welcome to Vi Hart Weekly! As you’ve probably noticed, a common thread between each Weekly is that each one has a theme, a common thread. This week’s theme is Common Threads.
1. Art of the Week: Where We Met
I live in SF and travel a lot, so I regularly get to pass under Janet Echelman’s “Every Beating Second” in the San Francinco airport. Last weekend I got to see one of her newest installations in Greensboro, NC, “Where We Met”, and it’s something else entirely. Outside, subject to the wind and weather and changes in light, it has a life and presence unlike any public art I’ve ever seen. Day and night, the park is full of people lying in the grass underneath gazing upward.
Perhaps because the sculpture is still relatively new, I overheard many conversations from people discussing the sculpture, an exercise in noticing, inventing and asking questions to each other. What does the shape have to do with the tension of the strings? Is the color at night because of the color of the art piece or the color of the lighting? What material is it made out of, how strong is it, how heavy do you think the entire sculpture is? Does the shape mean anything or is it just random?
It’s beautiful to overhear such focused noticing happening not in a gallery, but in a public park, by all sorts of groups of people. And quite wonderfully, answers to many of these questions can be found in the Greensboro History Museum right next to the sculpture, in an exhibit titled “Weaving Wonder with Historical Threads”. I was pleased to be able to touch some of the material the sculpture is made out of (hooray tactile learning!), as well as learn the secret behind the sculpture’s design, and its connection to the textile industry.
A related mini-exhibit, right inside the entrance to the museum, asks visitors to weave threads according to their own answers to a few questions (and the color thread depends on the visitor’s home location). I love the simplicity and tactility, and that the result is a sort of infographic data visualization thing.
2. Book of the Week: Dr. Montessori’s Own Handbook
Continuing the theme of education and active learning, and realizing that while I knew a lot about Montessori education but had never read anything written by Maria Montessori herself, I read “Dr. Montessori’s Own Handbook”. It’s quite interesting to read the very precise curriculum descriptions and motivations for every detail of every activity and how it contributes in subtle ways to a child’s future learning. While I was familiar with the overarching ideals and structure of Montessorian education, I hadn’t realized how detailed, thorough, and intentional a curriculum existed, one which apparently most schools labeled “Montessori” follow only in part, if at all.
Many of the educational materials and concepts she invented are familiar to me, but some seem to have been gotten left behind, including exercises involving feeling different materials, a children’s haptics library. Recall Margaret Minsky’s haptics library, which we discussed a couple weeks ago! Now I want to play the Montessorian game where I gather a bunch of material samples in pairs, mix them up, and have to pair them back up blindfolded, by developing and using various sorting strategies, as well as developing my ability to focus attention and achieve completion of a task, as well as learning the delicate touch and physical delight in my environment and all those things she describes so eloquently in her curriculum.
3. Noticing Math in Things of the Week: Jump Roping
I went to the National Folk Festival in Greensboro NC last weekend, and while I saw many excellent performances from all over the world (the festival is national but the folk is international), one particularly caught my mathematical interest.
I’d seen some competitive jump roping before, and it’s pretty impressive. But at the festival the Bouncing Bulldogs did some moves I’d never seen, involving multiple people holding more than one jump rope, for example three girls with three jump ropes between them, weaving themselves over and under the shared jump ropes in a way that must require a great deal of experience and intuition with certain topological patterns. Here’s the closest thing I could find on YouTube, by another group:
I’ve heard of jump ropes as an active educational tool for things like counting and number patterns (jumping rope while counting up by twos, down by odd numbers, or even just using the string of the jump rope to measure, braid, or… perhaps weave?), but there’s some deeper mathematics going on in these multi-person jump-roping tricks that I believe have yet to be vigorously studied. I think there’s a lot of fertile ground here, and the art of jump roping is ripe to be revolutionized by mathematics in the same way juggling was. Also, the world could always use more great mathematicians, so it would be good if we could figure out exactly how their intuition for these forms could transfer to existing mathematics.
4. Snake of the Week: This One Particular Rat Snake
This is my new snake friend! I didn’t realize they made them so big in North Carolina.
Not for jumping rope with.
5. Presidential Chocolate of the Week: Obama Kisses
Before North Carolina, I went to Washington DC to meet with some folks from the Office of Science and Technology Policy about active learning in mathematics. There’s not much to say about the meeting itself, besides that they seemed to pick a good group of people to meet with them, and if that meeting is the start of a conversation rather than a full one, it won’t have been a waste of time. Also it was nice to be recognized by the Chief Technology Officer of the United States, Megan Smith, who I think is pretty great. But the most tangible result of the meeting is that apparently when you have a fancy White House Meeting you get Obama Kisses. Every liberal’s dream. I’ve got to stick with this education policy thing so that I can dream of Hillary Hugs someday.
Each kiss is threaded with a paper ribbon that I was hoping would say something like “thanks for visiting, sure wanna hear more of your policy ideas later”, but it’s just the usual message of love:
I’ve got a lot of thoughts on the meeting, and education policy in general, that will take me some time to sort through and write up.
6. Never Forgetting of the Week: 9/11
The bulk of my family lives in North Carolina, and so while I was in the state, last night we had dinner together. Given the date, we got to remembering 9/11. Where we were when we heard, what our day was like, and of course, the family stories, which are not mine to tell.
As I was telling my own recollections of the day, which I haven’t thought about in many years, I couldn’t help but notice the difference in technology and communication between then and now. I was in school, and this was back when kids generally didn’t have cell phones, much less smart phones, much less laptops. Most classrooms didn’t have a computer, much less an internet-equipped computer. There was a loudspeaker announcement that told us about the plane crashing into the tower, and that announcement didn’t tell us why or how big the plane was or how bad the crash was and we were left to speculate, with no other way of gathering information, while the teachers were hearing the same thing we were, expected to go about the day as usual.
Oh, I should mention: this is in New York. I grew up in New York, and almost all my family lived there at the time. We have family and family friends who were in and around those towers. But by the sound of the initial announcement, it wasn’t serious, it was probably a small plane that accidentally crashed because of an instrument failure or something. So if I were to tell you where I was when I heard the news, well, I heard the news for the first time slowly, in many places, across the day, with increasing horror. I heard the news without twitter (which didn’t exist) or YouTube (which didn’t exist), I heard it without an iphone (which didn’t exist) or facebook (which didn’t exist). I heard it in bits and rumors, it was forbidden knowledge, the teachers weren’t supposed to be telling us any news, and generally the administration was trying to get the school through the day.
But our 2nd period teacher turned on the radio (a radio, an honest-to-goodness radio!) and we sat listening quietly all period. I was listening when the first tower went down, and when the second tower went down, and those of us who cried did our best to cry quietly, and then the bell rang and we went to the next classroom and tried to pretend everything was ok so that our rule-breaking teacher wouldn’t get in trouble for not keeping us in the dark.
As the day went on, in rumors and speculations not unlike twitter today, we tried to sort out what was real. The pentagon was attacked? Really? Surely that’s something a younger student made up?
It was a long school day. It ended. I went out to the pay phone and called home and finally learned that everyone was, whether by accident or skill, alive. And then at home we sat by the tv and watched the news, the same footage over and over and over and over
I learned not to obsess like that over horrific news footage ever again.
Today I’m coming home from visiting my family. I wrote this Weekly on my flight back to the west coast, and we’ll be descending back into SFO with its lovely Echelman sculpture soon, “Every Beating Second”. In the last airport, eating a sandwich before my connecting flight, I looked up and was shocked by the sight of the footage on the tv, the smoke billowing from the tower, the clear blue sky in the background. It hit me with a visceral force.
I remember smelling that smoke for a long time after. Our perfect blue skies never quite returned.
7. Child On A Plane of the Week
Despite that I’m not that into children or planes, I actually quite like children on planes. They’re a controlled and restrained breath of fresh air in a crowded box full of adults desperately pretending not to notice each other. The little girl in front of me is asking “Would you rather be a solar system, a hedgehog, or Hermione?”
It does sound very nice to be a solar system, but I think I’d most like to be Hermione, who with all her power and intelligence dedicated her life to doing what is right rather than what is easy.
Welcome back to Vi Hart weekly! This week we’ve got the robots of the week, embodiment, education and beer, turtles and snails.
1. Robots of the week
During a group discussion of collective intelligence, one of my colleagues brought up the work of Radhika Nagpal, which brought us to watching YouTube videos of the termite-like Termes robots she developed at the Self-Organizing Systems Research Lab at Harvard.
One thing led to another, and we started to act out robot algorithms on the floor. We were all aware of previous work using embodied acting-out-of-algorithms to help teach and understand them (examples include Andrea Hawksley’s Binary Dance workshop, folk-dance sorting algorithms, and even some of my own work with Mike Naylor on Human Geometry). But rather than follow up on any of that, we quickly filmed what we were doing and went home, and then I proceeded to edit together a ridiculous video to convey my full joy at the endeavor in which we had decided to partake.
2. People noticing patterns of the week
After seeing “Radhika’s Robots”, artist and collaborator Evelyn Eastmond sent me a message noting the connection to her latest video (above), which in fact I had seen just a couple days before. I’m glad Evelyn noticed this connection in form, because I completely missed it! We followed the form of the termite robots to amuse ourselves, while forgetting that this form also displays the weight and burden which the robots carry for the collective good.
A commenter on “Radhika’s Robots” noticed another connection:
In fact, a few other commenters referenced snails, saying, “Snail snail snail” and “Snail snail snail snail” and such. It’s a thing.
3. Paper of the week
The paper of the week is “Teaching Children to be Mathematicians vs. Teaching About Mathematics“, by Seymour Papert. No, wait, I changed my mind. The book of the week is going to be by Papert, so let’s have the paper of the week be “Children Learning by Doing“, by Alan Kay. It’s labeled “rough draft”, but it collects a lot of previous material he’s written about Squeak Etoys and learning into one place.
I’ve talked a lot with Alan about this particular work, and a couple months ago I started to make a prototype bringing some of these ideas to virtual reality. This week I started to do some more serious work on this prototype, so I wanted to dig deeper into a lot of the stuff we talked about, and get more context for the conversations we’ve had about learning and math education in general.
Alan has a lots of faith in children’s ability to understand deeply complex ideas, if they have the right support. I haven’t done much educational material on purpose, but as long as the things I make tend to often fall into that category by accident, it’s good to get a deeper background into what’s already been done.
4. Book of the week:
The book of the week is Mindstorms by Seymour Papert. This is a classic on computers in education (really THE book), yet somehow I hadn’t read it until now. After reading some of Papert’s other papers this week though, and realizing just how good he is, I couldn’t resist!
Above is a picture from the cover of one of the editions, showing the “Turtle” robot that can be programmed by simple instructions in LOGO, the language Papert developed with children in mind.
Mindstorms is great. I love the emphasis on the culture and context of education that allows children to be immersed in mathematics, the same way languages are best learned when immersed. I love that he highlights debugging as being a powerful intellectual tool for emphasizing process and progress over right or wrong results. I love that he talks about how a large part of what mathematicians do happens before equations get written down, that mathematical thinking is not just about logical processes but includes this other thing that lets us know when and where to apply those logical processes, the creativity and intuition that point our logic in the right direction.
And of course there is the common thread with my current research group about tools-to-think-with, and when applied to education this means putting children in the context where mathematical tools are the tools they need to think with to reach their goal. Learning mathematical tools is a means, not an end.
There’s a lot I can say about this book, and it’s easy for me to see many ways in which it has influenced the thinking of people I know and of the education system at large. I recommend it.
5. What’s up at eleVR
The prototype of Real Virtual Physics is at a place where I’ve started sharing and writing about it. And being kept up at night by new ideas for toys to add to it.
There’s something profound about having real-time feedback based on your body’s motion that can give you a feel for how things behave. That’s part of how I’ve always thought about mathematics: the art of understanding how abstract objects behave.
In Mindstorms, Papert likens understanding mathematics to understanding a crowded room of strangers. It might take a while to get to know them, and introductions help, but in the end it’s all about your own personal connection with those people and understanding how they behave, how they react, what they do and why. It’s a good metaphor. When giving mathematical objects abstract inputs that must be computed by hand or one by one through a computer, it’s difficult to get information on how things behave. But real-time feedback based on your own body’s movements makes it so easy to explore, if only we had the tools to do so. So I guess I’ll keep working on making those.
6. Beer of the Week
No Hero, by Evil Twin Brewing. It’s a simple dark and lovely oatmeal stout in a world of overly-ambitious too-many-flavours stouts, and it comes in a can. It’s got a bitter finish without the bother of being all hoppy, chocolatey, or coffeey. No Hero works behind the scenes to save the day.
Welcome back to Vi Hart weekly, where I try to brain–dump my brain–thoughts for the week. This week we’ve got noticing patterns, soviet sci fi, beer, games, AR, haptics, and more?
1. New Brain Toy of the Week
Inspired by Sol LeWitt’s PhotoGrids, a book in which he takes pictures of grids all over the world (echoing his other art), I’ve started taking pictures of patterns and mathy things and grids and things, and also collecting other examples of people becoming close to a pattern and then collecting it as they notice it in the world (Pareidolia, The Witness, etc). I’m a meta-collector of pattern collections, because once I became sensitized to their existence, I’ve started seeing pattern collections everywhere.
2. The state of the Vi Hart
Things are coming together at my new job at HARC. It is awesome to be able to actually get up in the morning thinking about my actual work, and getting straight to that actual work, and having my actual work be the thing I think about when I’m trying to sleep at night, rather than a pile of other bullshit. I realized yesterday that for the first time in years, I don’t feel burnt out. It is a really good feeling.
I’ll post more about my new research group another time!
3. What’s up at eleVR
This week, Andrea posted about a project she did last year, laser cutting some parts to convert a Wearality headset setup into an AR device. I had some footage from October 2015 of when she first hacked it together, and edited that along with some new footage of the thing adding some AR sculptures to a physical exhibit (above).
I’ve also been working on our virtual Sol LeWitt forgery, and posted almost a week ago on techniques for collision in VR.
4. Sci Fi Book of the Week: Roadside Picnic
Roadside Picnic, by Arkady and Boris Strugatsky, is a 1971 Soviet “rediscovered classic”. As a big fan of scifi, classics, and Russian lit, this was an obvious “yes” for me, and I got pretty much what I expected: an enjoyable quick read with a couple compelling takeaways. It strikes me as a spiritual predecessor to one of my favourite recent scifi series, Annihilation by Jeff VanderMeer (2014) and its sequels. If you’re into scifi about mysterious creepy Zones, with a little bit of social criticism and the occasional very unsympathetic main character, these books.
Suggested by Evelyn Eastmond, related to my work generating Sol LeWitt wall drawings in VR. A good overview of how complexity theory is applicable to generative art, and I have a feeling it’s going to come in handy as a reference in the future.
6. Beer of the Week: Groovalistic by Shady Oak
It’s got that fun funky flavor that would taste unwise in anything but a fermented beverage. It’s heavily hopped in a way that makes it taste more like beer rather than more like hops, rare in a West Coast beer these days. Brett and hops are combined perfectly to create something that tastes like one consistent funk, rather than a pile of hops and a pile of yeast thrown haphazardly together. Strong flavor but not a novelty.
7. Game of the Week: Kingdom: New Lands
I’ve been playing a little more of this than is probably wise. I just love this side-scrolling strategic tower defense, with its pixel arts, atmospheric music, and the sense of desperation and regret as simple mistakes cause slow inevitable permadeath. I love my terrible constantly-out-of-breath horse, and bear, and unicorn that shits gold. I love trying to optimize and correct for shortages, without over-correcting or causing oscillations in the system.
A 1995 haptics classic, back when computers could do anything. A good read, with lots of still-relevant ideas, plus other interesting bits such as that Ping Pong balls are useful as an object with the most “haptic neutrality” (and that they are in fact made with cellulose, not plastic).
I was moved to read it after talking with Emily Eifler about the idea of imaginary materials, things that could be simulated once we have good haptics technology that use combinations of sensations that would not exist in real materials. I thought: “probably Margaret already wrote about this 20 years ago”. Indeed, she talks about simulating materials with negative friction/viscosity, which apparently got interpreted as being slippery, with more research needed (see section 1.6).
In the same section, she calls for a “World Haptics Library,” saying:
During the course of my thesis research I touched many materials with a heightened introspective stance. When I found the limitations of simulation confounding, I went to my own fabric closet to feel cloth, to my garage to feel sandpaper, outdoors to feel stones and shells. I was creating and returning to my own library of materials for inspiration, to re-familiarize myself with the wide range of sensation and the evocative associations available from simple classes of materials.
Another example for my collection of people collecting things they have become sensitized to noticing!
OK. So. There’s some tension goin on in the United States, and most media outlets and politicians are so out of their depth that they’re trying to deal with it by repeating the same old “we need to be united, violence is not the answer.” Which is all very well and good, but being united is an ideal, not a plan. And without a plan, all it translates to is “be united by joining me in doing nothing! Don’t speak out or protest because that’s divisive from my non-plan!”
Meanwhile leaders within the Black Lives Matter movement have concrete plans, plans for increasing police training for deescalation, plans for ways bad apple police officers could be held accountable so we don’t keep seeing non-indictments, plans for changing the incentives and structures around fine collection so that targeting the most vulnerable people is no longer the most profitable thing for police to do, there’s so many good changes that should be made and it’s frustrating to see the media spin it into “what is the exact problem to point at? is it that police are racist? or is it that there aren’t enough body cameras? or maybe the problem is purely socio-economic.” And the media spins it as exclusive ors, as if complex problems don’t come from complex combinations of causes and feedback loops in complex systems.
I know a whole lot of you are still catching up on events, and black organizers of social change don’t have time to give 101 courses to every internet person who is of the opinion that “if you just do what police say you’ll be fine” and “All Lives Matter”. Listening to black people is important, and white people have got to talk to other white people to try and get up to speed and learn how to listen. Hence this video.
Here we go.
Black Lives Matter was founded in July 2013 by three black women, Patrisse Cullors, Alicia Garza, and Opal Tometi, in response to George Zimmerman being acquitted after killing 17-year-old Trayvon Martin. If Zimmerman had faced consequences for his actions, maybe it could have been spun as a tragic event involving a lone overzealous racial profiling neighborhood watchman, but the system supported Zimmerman, he was acquitted, thus people feeling the need for a movement specifically focused on the problems that make our justice system treat black lives as mattering less than white ones.
And there’s many such problems, but we’re gonna skip to July 2014 when Eric Garner was killed by police and it was captured on video and the world said I can’t breathe. His death alone was cause for protest but the media reaction and statements made by politicians made it clear that black lives were being treated as mattering less, like the absurd focus on how he was selling loose cigarettes, or how he had asthma which made him easier to kill anyway, it was really messed up. His death was ruled a homicide but there were no indictments.
August 5 2014 John Crawford III shot in a walmart while carrying a toy gun that walmart sells, in Ohio, which may I remind you is an open carry state. Someone called 911 reporting that John Crawford was pointing a gun at children, and there’s a chilling video where he’s standing there chatting on the phone with the toy gun point down, no one else in sight, certainly no children, when suddenly the police rush in and start shooting immediately. Once again, no indictments.
August 9 2014 Michael Brown was shot by Ferguson police. That he was shot, again itself was cause for protest, but the media reaction and police response and outpouring of support for Darren Wilson, the police officer who shot Michael Brown, was all really worrying to a lot of people. And when Wilson was not indicted, that once again sent the message that this was not just a mistake made by bad police, but something allowed by our justice system and supported by a lot of American citizens.
November 2014 Tamir Rice, a 12-year old kid, killed by police. Again there’s a messed up video where he’s playing by himself in a park with a toy gun, also in Ohio, and the cop car speeds up to him and an officer shoots him within two seconds of stopping. Once again, no indictment, and somehow some media outlets saw fit to start reporting on the criminal records of this 12-year-old victim’s parents.
April 2015, Freddie Gray disappears into a police vehicle and comes out with injuries so severe he goes into a coma and dies a week later. Again, there are protests. Freddie Gray’s death was ruled a homicide, and it turned out there was no cause to arrest him in the first place. There’s still some ongoing trials but the only completed trial had the result everyone was dreading, Edward Nero was found not guilty on all charges.
July 2015 Sandra Bland, a vocal supporter of Black Lives Matter, gets pulled over for failing to signal a lane change, and there’s a video where the officer absurdly escalates it into an arrest. The officer involved ended up getting indicted for perjury, but no indictments have been made in connection with how Sandra Bland was found dead in her cell 3 days later. It appeared to be a suicide but an investigation revealed some weird inconsistencies and the results have not come out yet, it’s ongoing.
So many other people I could name, but I’m gonna skip to this past week.
July 5th, 2016, Alton Sterling, having just been tased, is held down, face down lying on the ground by two officers, and is shot multiple times, and it’s all on video from multiple angles because he was shot to death in front of his friends. It’s so clear, so unspeakably sickening, and yet the media starts to talk about well he shouldn’t have been selling CDs anyway and let’s hear both sides of the story, maybe it’s ok to shoot someone who you think has a gun in their pocket, maybe it’s ok even if you’re already holding them down after tasing them, isn’t that such nice balanced news coverage.
The very next day, July 6th, Philando Castile gets pulled over for a broken tail light, his girlfriend Diamond Reynolds is next to him, kid in the back. They comply with everything the officer asks and they inform the officer that he has a concealed carry permit and is carrying a legal firearm, and the cop shoots him multiple times. She starts streaming video and the contrast between her trying her best to calmly comply even as the cop is screaming and pointing a gun at her and her dying boyfriend… realize how absurdly inappropriate it is that some media outlets followed this up with an accounting of how many tickets he has gotten, because that’s the worst dirt they could find to excuse his death. Do not let anyone make excuses for this man’s death. Do not let them excuse it with tickets.
All those events and more led to protests around the world, and some people exploited some of those protests as a chance to loot and cause damage. On July 7th 2016, someone exploited a protest to set up an ambush against police. A lot of media outlets and politicians are trying to spin a dangerously irresponsible narrative where it’s a war between Black Lives Matter and Cops rather than that the sniper was a messed-up loner with a grudge, who was himself military, who said he had no connection with Black Lives Matter, who simply took advantage of knowing there’d be heavy police presence at a protest.
Pretending otherwise is just an excuse to discredit Black Lives Matter and ignore their very reasonable requests.
The officers who were killed are being treated with dignity and respect as they should be. No one reported about those officers’ past infractions or how many complaints had been made against them or their family members’ criminal records. No politicians spoke out in support of the killer, the NRA didn’t put out a statement supporting his second amendment rights, and televised news didn’t replay the footage of their deaths over and over and over speculating that maybe they would have lived if they’d just taken cover here or had worn different equipment, no one speculated whether a medical condition may have contributed to any of the officer’s deaths. There’s no campaign raising hundreds of thousands of dollars in support of the man who shot those officers, he’s not on national news telling his side of the story in some twisted mockery of fair and balanced reporting, the man who committed these killings was blown up by a robot.
Let’s not forget the thing that makes a black person expressing anger about white people on the street or in a tweet a very different thing from a mainstream politician backed by voters demeaning black people on national TV. Let’s not forget the imbalance of power that makes racism “racism”, rather than just prejudice, and the imbalance of power that makes racial profiling from police doubly harmful. Police are backed by institutional power and many do use this power wisely to protect the safety of American citizens, but when someone backed with that kind of power does wrong, again and again we see them not facing consequences. We can’t force a jury to indict someone, but we can protest, so we protest.
I hear people talk about how white people and people of color besides black people also get unfairly killed by police, or that there’s other crime too, and the system is unfair to other people too, and that’s all the more reason that we’re all in this together. Some people have more at stake, but this is all our problem.
I’ve put this all very mildly. My heart goes out to those who don’t put it mildly, to those who are angry and afraid, who raise their voices and don’t have energy left over at the end of the day to be extra nice to those who still don’t get it. I know there’s a lot of white people out there who are afraid or unsure of whether or how to engage with any of this because they’re afraid of doing it wrong or being called racist when they’re just trying to help, and, I sympathize, but you’ll live. So go listen and learn and good luck everybody.
We’ve been spending some time lately organizing our many projects and blog posts, and I’m constantly amazed at how much we’ve done. So many experiments forgotten and dug up as we go through old bits of research.
