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.

**Our office,
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!

We encourage students to come to our **Thursday events, held in 1015 Evans**, 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.

Most annoucements are done over MUSA's mailing list.

MUSA strives to make the math department as inclusive as possible. How are we doing? Let us know with our anonymous feedback form.

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
can be seen in the calendar.

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)

Prof. Tim Laux

Friday, 15 February — 748 Evans

Abstract: Gradient flows are differential equations. They arise in physical systems driven by the relaxation of energy or entropy. In the talk I will give some basic examples and will show that the natural time discretization of a gradient flow even makes sense in general metric spaces. At these examples we'll learn to appreciate the importance of the metric, not only the energy/entropy. While this abstract viewpoint is great for pure mathematicians, it did not find many followers in the applied community until very concrete applications in PDEs were discovered. At the end of the talk I will show a recent application in which this viewpoint is the basis of a convergence proof of a numerical scheme for mean curvature flow.

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. (Archive)
