Friday math movie - Mathemagic
By Murray Bourne, 01 Feb 2008
This week's movie comes from TED Talks:
In a lively show, "mathemagician" Arthur Benjamin races a team of calculators to figure out 3-digit squares in his head, performs a massive mental calculation, and guesses a few birth days
This reminds me of Vedic Math and Trachtenberg math.
