The following is a tutorial about how to make the Yoshimoto cube using paper (though it takes a very long time!). To make it you’ll need paper, scissors, some glue, and some adhesive tape.
With my YouTube-Video I will demonstrate that “2 = Square root of 2”. Where is the mistake? In spite of the fact that the text of this proof is written in German, you could understand it without knowledge of this language.
Thanks to Ortmar Buss (ojbuss) for this submission!
Looks like a promising movie:
In honor of Pi day, enjoy watching this 3 hour 14 minutes and 15 seconds long video of Pi!
* “almost” every digit of pi**
** and by “almost” we mean only a small finite number of digits of pi
Happy Pi Day!
