If you like maths or people being awesome with numbers, check out Arthur Benjamin over at TED Talks. He squares three digit numbers faster than calculators can, but most interesting was him ‘thinking out loud’ while squaring a five digit number - he seemed to use variables to store calculated values to come back to later. A great 15 minute video.
