Currently reading One Two Three… Infinity by George Gamow.
Here is a little science demonstration inspired by a section on the topology of the cosmos.
Some things I discovered while working on this video:
You can’t make the kind of Möbius strip that I did by nesting two Möbius strips together: you can’t nest two Möbius strips and have one follow the contours of the other all the way around.
If you construct this, and pull it apart so that it hangs loosely as a single loop of paper, it’s very difficult to put it back the way it was. It’s kind of a puzzle.
Here are some other cool Möbius strip related videos I like:
A superconducting vehicle that runs on a magnet covered Möbius strip.
One of my favorites, Vi Hart, showing off a Möbius music box.
