presents

*MATHEMATICS CAL DAY 2017*

**Information Session: The Mathematics Major**

L. Craig Evans, Professor

9:00 - 10:00 AM @ 60 Evans Hall

Learn about objectives, requirements and opportunities for students who major in Mathematics. Staff advisers will be available to answer questions.

**Ask the Mathematician**

George Bergman, Professor

9:00 AM - 3:00 PM @ East entrance of Evans Hall

Find out everything you always wanted to know (but couldn't find anyone to ask) about math. A Cal Day favorite!

**Mathematics Information Tables**

10:00 AM - 3:00 PM @ 1015 Evans Hall

Talk to Math Department advisers and members of MUSA (Math Undergraduate Student Association) and get comprehensive information about the major and minor programs.

**Origami, Lasers and Other Fun Math Games**

10:00 AM - 3:00 PM @ 1015 Evans Hall

Come play math games with us! At our origami station, learn how to construct familiar objects and polyhedra out of paper. Play "Set"--a popular game of pattern recognition--and race your peers in finding patterns in groups of shapes. And solve a laser puzzle by placing light-bending tokens on our Laser Maze single-player board game. **Get your Science at Cal Passport stamped here!**

**Women Who Figure: An Exhibit Inspired by the Mathematicians of Hidden Figures**

10:00 AM - 3:00 PM @ 100 Evans Hall (Math/Stat Library)

Inspired by the book and film *Hidden Figures*, this exhibit focuses on the three women at its center, and other women who have made important contributions to mathematics throughout history. The exhibit includes works from the Mathematics and Statistics Library collection about these famous women in mathematics and related fields. **This is a stop on the Library Passport!**

**Math Talks with Faculty**

Members of our
distinguished faculty will present talks of general interest to the
informed public. All lectures are located in **60 Evans Hall**. The talks are always popular with Cal Day attendees!

**Fibonacci Numbers and the Golden Ratio
**

Brent Nelson, NSF Postdoctural Scholar

10:15 - 11:15 AM

The Fibonacci numbers are perhaps the most famous sequence of numbers in mathematics. It turns out that what drives their behavior is the so-called golden ratio, phi. We will explore the mathematics behind this connection and the surprising appearances of these concepts in nature.

**Introduction to Fractals: What is the Mandelbrot Set?**

Alexander Paulin, Lecturer

12:45 - 1:45 PM

You have perhaps heard of fractals: those crazy, self-repeating patterns that seem to get even crazier the closer you look at them. In this talk, I'll explain the most famous fractal of all: the Mandelbrot Set. You might think that this would require lots of advanced mathematics. Amazingly, all we'll need is addition, multiplication and a good deal of imagination!

**Math Peer Advisor Panel Presentation**

2:00 PM - 3:00 PM @ 60 Evans Hall

In this panel discussion, the Math Department peer advisors will answer questions about the math and applied math major programs as well as the undergraduate experience at UC Berkeley.
