Curious about more math this Pi Day? Here’s the problem we included in this year’s Pi Day card:

Problem:

Two logicians (A and B) each secretly pick a whole number from 1 to 30, inclusive. They have the following conversation:

A: “Is your number double mine?”
B. “I don’t know. Is your number double mine?”
A. “I don’t know. Is your number half mine?”
B: “I don’t know. Is your number half mine?”
A: “I don’t know.” 

B: “I know your number.”

All the statements are true. What is A’s number and how did B know?

Pizza holds a special place in our hearts at BEAM. From the very beginning, through the challenges of COVID, we’ve shared pizza (even when we could only do it virtually) and built community together. So this Pi Day we’re spotlighting the humble pizza pie. Since it’s impossible to share an actual pizza with you all, we’re doing the next best thing — sharing a theorem about sharing pizza, the aptly named pizza theorem.

We are immensely proud to announce the recipients of the Jane Street and Hudson River Trading Summer STEM Stipends, awarded to BEAM high school students in partnership with Jane Street Capital and Hudson River Trading.
