# Caltech Undergraduate Math Seminar

## Winter 2017

Welcome to the webpage for the Caltech mathematics undergraduate seminar. The seminar is held two to four times per month, on **Fridays from 12:00pm to 1:00pm in 151 Sloan.** The talks are given by and for Caltech undergrads. Pizza is typically served. We are thankful to the Caltech math department, the Center for Teaching, Learning, and Outreach, and the Associated Students of the California Institute of Technology for funding.

The primary goal of the undergraduate math club is to foster a community among caltech undergraduates interested in math, breaking divisions across social groups and forming connections outside of the "is taking a class concurrently with" graph. Additionally, the club serves to foster the speaking ability of young mathematicians through its mentorship program: senior members of the club meet with underclassmen to nurture ideas for talks, to give general advice on talk-giving, and to give specific feedback on practice talks.
