    Benjamin makes numbers dance. In his day job, he's a professor of mathematics at Harvey Mudd College; in his other day job, he's a "Mathemagician," taking the stage to perform high-speed mental calculations, memorisations and other astounding mathematic stunts. It's part of his drive to teach math and mental agility in interesting ways, following in the footsteps of such heroes as Martin Gardner.

    The calculators deserve a round of applause for calculating as fast as him.

    I loved the "Light, Tomorrow" moment to describe 51,134, because he is uses the same memory trick my father taught me as a 10 year old in 1980 to remember card sequences. It is really useful and anyone can learn it. When he says he's "storing numbers" in a "phonetic code", he means he is comitting the number to an image (made of words) and when he wants to recall the number he just reaches for the words and (if you know the trick) you can reconvert the words to the number. The sequence he is using is the classic "peg sequence" from Harry Lorayne: Tie = 1, Noah = 2, Ma = 3, Rye = 4, Law = 5 etc. So Light = 5 and 1 (L and T), and Tomorrow is the 1 and 3 and 4 (T and M and R).

    I like how he takes more time saying the answer than he does solving the problem

    This is not easy. He worked his whole career on it. Made researches and had all those sleepless nights thinking of them. Everything the person puts an effort on, becomes this wholesome.

    The fact that he can instantly run through tons of numbers in his head to get the answer literally blows my mind and I can not even begin to comprehend how his brain possibly does it
