Jane Street will be hosting an Estimathon on January 30th at 2pm in APM B402A. 

The Estimathon is a mind-bending mixture of math and trivia. In teams, you'll attempt 13 Fermi problems in 30 minutes, ranging from totally trivial to positively Putnamesque. Be prepared to come up with the best set of confidence intervals! Sample problems include:

• How many stop signs are in New York City?
• How many babies were born in 1900?
• How many Social Security Numbers are prime?

Register here by January 26th @ 11:59pm PT. All participants will register as an individual and teams will be created on-site. We will confirm your attendance with the event location by January 27th.
