We are the Mathematics Undergraduate Student Association of the University of California, Berkeley!
We strive to improve the overall quality of studying mathematics here as an undergraduate, especially by advocating for issues that benefit the entire undergraduate math community, not only the subset that attends our events.
Joining MUSA is an excellent way to connect with other math enthusiasts. You can learn about the many opportunities for math students, including little tricks that will help you survive the rigorous math curriculum here.
938 Evans, is usually open, selling hoodies and food — but we encourage students to come in just
to chat about math or life. We won't bite!
In lieu of operating out of 938 Evans, we now have a Discord server for students to chat and socialize! Office hours are also held 12-5PM on weekdays over Discord voice chats.
We encourage students to come to our Thursday events, held over Zoom where you can meet fellow math geeks and get valuable information. Our events are open to the public, not just declared math majors — so don't be a stranger!
You can also purchase t-shirts and hoodies online with our MUSA Merchandise Mail Order Form.
MUSA strives to make the math department as inclusive as possible. How are we doing? Let us know with our anonymous feedback form.
We are still looking for mentors and mentees for our Berkeley Undergraduate Mathementoring Program, BUMP. Learn more about BUMP here.
Most annoucements are done over MUSA's mailing list.
We hold events every week throughout the semester. Typically, our events are held at 6pm-8pm at Evans 1015, the top floor lounge of Evans Hall. Our upcoming events are usually posted on our Facebook group.
The Math Monday undergraduate lecture series is the flagship event of MUSA. It is a series of talks, every Monday at 5 PM, given by professors and other academics about mathematical research and special topics. (Archive)
At MUSA, we love to talk about tricky math problems of all levels! Here's some of our favorite problems. If you can't figure them out yourself, try asking at office hours and see if anyone else can make heads or tails of them.
A fair coin is repeatedly flipped until 2019 consecutive coin flips are the same. Compute the probability that the first and last flips of the coin come up differently.
