Pi Is (still) Wrong [permalink]

I don't usually blog about politics, but it was time to take a stand. I am anti-pi, and you should be too!

How to eat Candy Buttons like a Recreational Mathemusician [permalink]

Another video!

This one is done YouTube-style, but I'll get the non-YouTube one up along with a page in the candy section of the mathematical food page sometime in the future.

You can also now 'like' my new facebook page, if you like.

New Video: Doodling Snakes + Graphs [permalink]

I just finished the third and possibly final video in the Mathematical Doodling series:

The three videos are now on this webpage, which maybe someday I'll update with some more explanation and info, but for now just has helpful Wikipedia links.

New Video: Doodling Stars [permalink]

I had so much fun with the last doodling video that I decided to do it again, with another of my favourite old doodles from my high school days: stars.

New Video: Doodling in Math Class [permalink]

I was doodling in my notebook last night, and started thinking of all the mathematical doodles I used to do during class. I considered making a small webpage about it, but decided to do this instead:

Thank you to all the people I know whose math classes do not require such pastimes!

Waves In Glass [permalink]

I wrote the music for this video by Erik and Martin Demaine, for their project Waves In Glass, which combines mathematics, paper folding, and blind-folded glassblowing.

When writing this music, I tried to capture the repetitive rotational feel in the process of both glassblowing and this particular instance of paper folding, as well as sneaking in elements of symmetry and mathematics. I see this video as a collaboration and communication between art, glass, music, math, paper, and people.

Last Quintet for Burning Paper Instruments [permalink]

What follows is a montage of video clips from a long improvisation, playing instruments made of paper while they are on fire, from lighting the first didgeridoo to dousing the last. Many thanks to Hendrik Goris, Anton Maes, Frank Maes, and Geert Vrolix for playing with fire with me. (Disclaimer: burning stuff is dangerous.)

Pachelbel's Music Box Canon [permalink]

My second arrangement for music box is Pachelbel's Canon in D. Three music boxes play the same strip of paper in sequence, creating a canon. The basso continuo is created by another music box playing a loop of paper. This arrangement really lets you see the structure of Pachelbel's original canon!

Möbius Music Box [permalink]

I recieved a music box melody making kit from Tim Nissen, who I worked with on the Organ Function Grinder. My first arrangement for music box is a theme from the Harry Potter Septet. Being a mathematician, I twisted the paper into a Möbius strip and made this educational video to demonstrate:

For comparison, you can listen to the theme in piano from the Harry Potter Septet. This section is inspired by Dumbledore's speech at the end of Book 4, and spans from the theme entrance to the end of the movement.

Autorequiem for Tube Harp [permalink]

A month ago, we played instruments made of paper while they were on fire. What follows is a video of one piece from that night, Autorequiem for Tube Harp—a self-inflicted song of death. Luckily, this flaming instrument's last song has been recorded for your viewing and listening pleasure:
