Ethan Brown, Mathemagician

Ethan Brown is a 12 year old “Mathemagician.” After watching an online video of Arthur Benjamin’s performance at TED, Ethan was inspired to learn the art and science of performing Mental Mathematics on stage. He began with a 5th grade talent show in May 2010 and only 1 month later joined Dr. Benjamin onstage at The World Science Festival in NYC. Since then, he has performed at The Chicago Toy and Game Fair, The World Science Festival Street Fair, Skepticamp, Boston Skeptics, and various schools throughout Connecticut. Ethan loves showing people how math can be fun and entertaining.

Ethan writes a math blog at and has his own website  His math blog is full of interesting (and pretty difficult) math problems, conundrums, and facts.  His website has information about performances along with links and testimonials.

On May 6, Ethan will attempt to set a world record by reciting from memory the first 2000 digits of Tau (which is 2 times Pi)  The event will take place at the Bethel Public Library in Bethel, CT.  Although the World Record part is not open to the public, the library is hosting a public event including magic shows, math workshops, and a number of other events. (And assuming he is successful, the announcement of the record will be public)
