The Department of Mathematics presents Cal Day

April 22, 2023


Cal Day Events



Title: MUSA (Mathematics Undergraduate Student Association)

Description: Meet current math students. The Math Undergraduate Student Association (MUSA) serves the undergraduate math community at Berkeley, providing a range of opportunities to connect and expand horizons. Hear the perspectives and experiences of students in one of the top math departments in the country. We'd love to have you join us!
Type: In-person.
Audience: New admits.
Time/Location: 9:00 a.m. - 3:00 p.m. East entrance of Evans Hall.



Title: Mathematics Information Session with Professor Richard Borcherds, Department of Mathematics /Major Advisors

Description: Learn about objectives and requirements of the Math major and the opportunities open to math students at Berkeley. Staff advisors will also be available to answer questions.
Type: In-person
Audience: New admits.
Time/Location: 10:00 a.m. - 11:00 a.m. Room 60 Evans Hall.


Title: Ask The Mathematician, Professor George Bergman

Description: A Cal Day Favorite! Find out everything you always wanted to know about mathematics (but couldn’t find anyone to ask).
Type: In-person.
Audience: New admits.
Time/Location: 10:00 a.m. - 3:00 p.m. East side of Evans Hall(outside).



Title:Surprising Applications of Polynomials, Professor Ruixiang Zhang

Description: Given n points on the plane, what is the smallest number of distances determined by all possible point pairs? Given n lines on a plane, what is the maximal number of points, each lying on k (>2) given lines? Given n lines in the three dimensional space, what is the maximal number of points, each lying on 3 non-coplanar given lines? As you may not expect, the three problems above are all somewhat deeper than their elementary appearances, and can all be efficiently dealt with by introducing auxiliary polynomials. I will describe this mysterious phenomenon and explain the role of polynomials in recently-proved theorems concerning the problems. The three problems also have far-reaching connections to properties of fractal sets and stability of waves. I will finish by describing some interesting properties of zero sets of polynomials that are important in these applications.
Type: In-person.
Audience: New admits.
Time/location 11:15am-12:15pm. Room 60 Evans Hall.



Title: Mathematics Information Tables

Description: Talk to advisers in the Department of Mathematics and get comprehensive information about the Major and Minor programs.

Title: Info Session with Gender Equity Mathematics (GEM)

Description: GEM is a student organization which serves to support women and other underrepresented genders interested in math at Cal. We host weekly meetings which alternate between academic opportunities and social events, in addition to offering a variety of other programs. Join our info session to learn more and ask us questions. We look forward to meeting you!
Type: In-person.
Audience: New admits.
Time/Location: 12:00 p.m. - 2:00 p.m. Room 1015 Evans Hall.
