Math Acrobatics

The youtuber 3blue1brown has a number of interesting posts. however often he is a bit fast for me and it seems handwaving.

Recently he made a fantastic video about solving the towers of hanoi. I did already know it is easy to spell out the solution in terms of recursion. However he showed some connection to binary and ternary numbers - which alone is funny. And finally that the solution also traverses the Sierpinsky triangle in part 2 which is surprising.

I embeded the videos after the “post” fold for convenient watching.
