Summary
A Mathematics Edition of TechBrunch, a small early-morning brunch for people who appreciate the rigor of pure mathematics and its connections to computer science. The session is billed as "The Proof of the Pudding is Left as an Exercise for the Eater" and explores the mathematical structures that underpin programming. Attendees share and dissect favorite theorems, proofs or concepts and discuss where math and programming meet. It suits mathematicians, computer scientists, and developers curious about the mathematical foundations of their craft. The group meets at the Beltempo restaurant in Hotel Metropolitan Edmont, Iidabashi; first-time attendees who RSVP and are confirmed get their meal free. It is a small group, and RSVP is needed to be sure of finding the table.
