The United Math Circles Foundation is an official umbrella organization for the Berkeley Math Circle. The United Math Circl
es Foundation is a non-profit organization.
The Berkeley Math Circle (BMC) is a weekly program for over 500 San Francisco Bay Area elementary, middle and high school students. The weekly sessions are held on Wednesday evenings at the UC Berkeley campus. The program is jointly sponsored by the:
- UC Berkeley Mathematics Department
- UC Berkeley Economics Department
- UC Berkeley HAAS School Of Business
- UC Berkeley Statistics Department
- UC Berkeley Electrical Engineering and Computer Science (EECS) Department
- Mathematical Science and Research Institute (MSRI)
- Simons Institute for Theory of Computing
- The Berkeley Artificial Intelligence Research Lab (BAIR)
- Vanguard Charitable, and
- Parents' Contribution
Emulating famous Eastern European models, the program aims at drawing kids to mathematics, preparing them for mathematical contests, introducing them to the wonders of beautiful mathematical theories, and encouraging them to undertake future careers linked with mathematics, whether as mathematicians, mathematics educators, economists, or business entrepreneurs.

MTRW Spring 2023 Program information
Spring 2023 Dates:
- First day of class: January 16th, 2023
- Last day of class: May 1st, 2023
We will have 15 Mondays of class, including Martin Luther King Jr. Day (January 16th). However, we will have March 27th off (UC Berkeley Spring Break).
Projected modes for Spring 2023
We will only be offering HYBRID mode for enrollment (with the exception of the possible 8B remote cohort, discussed below). This means all families should be prepared for both possibilities: online sessions and in-person sessions.
As of early December, we anticipate that MTRW sessions in the Spring 2023 semester will be held IN-PERSON, possibly with occasional online sessions as needed. This plan is contingent on compliance with local and campus health guidelines. The safety of our students, faculty, and staff is of utmost importance, and there is a chance that MTRW classes may have to return to remote status at some point. Local and campus health guidelines will be considered before making such a call.
If there is sufficient demand, we expect to have two cohorts of 8B students -- one expected to meet on campus (with a switch to remote status only if needed for health and safety reasons), and one that will meet exclusively online for the entire semester.
Families must commit to attending online AND in-person sessions of MTRW in Spring 2023, regardless of when/whether a change of mode may occur (with the exception of the 8B remote cohort, which will definitely meet online only). It is possible, but unlikely, that a move to remote classes is necessary for some MTRW groups but not for others, in which case siblings may be split between attending on campus and attending online at the same time.
Once enrolled students have paid their enrollment fees, no refunds will be provided to families, regardless of changed personal circumstances or if sessions move between in-person and online modes.

Hanna Hantao Chen Achieves at Math Prize for Girls!
Math Prize for Girls is the world’s largest math prize for young women high school age or younger. Hanna tied for 16th out of 300 girls, got an Honorable Mention, and was invited to the next round of competition!
Harry Main-Luu, previous assistant for MTRW and BMC-Upper, was named one of the 4 UC Berkeley University Medal runners-up!
"Every year, the competition for the University Medal – the award given each year to the graduating senior who best embodies the highest ideals of UC Berkeley – is fierce. Candidates for the medal, which was established in 1871, must have overcome significant challenges, had an impact on the lives of others and carry a GPA of 3.96 or higher."

Espen Slettnes Wins First Place at 2018 Broadcom MASTERS and Receives Minor Planet named after him!
Our very own seasoned math circler Espen continues to reap awards. Among more than 900 winners from regional science fairs in California, he went on to win both the 1st prize in Mathematical Science as well as Project of the Year Award across all categories in the junior division at the 2018 California Science and Engineering Fair.
In other math-related fields, he received a bronze medal at 2018 USA Physics Olympiad (USAPhO). He is also competing in the Gold division of the USA Computing Olympiad (USACO), having easily aced the Bronze and Silver divisions last year.
He has also been accepted as one of 45 pre-college students worldwide to form the inaugural cohort of World Science Scholars, a new initiative to nurture the next generation science researchers, led by Professor Brian Greene of Columbia University. The scholars will explore a broad range of new disciplines expanded from mathematics. The video above includes footage from MAA MathFest 2018 in Denver earlier this month; near the end, Espen is talking to Dr. Michael Pearson, executive director of MAA.
More recently, Espen won first place (out of 80,000 middle school students who competed) at 2018 Broadcom MASTERS! This competition is the premier science and engineering competition for middle school students and is a national science fair organized by The Society for Science and Public. He was also selected out of a gifted, national applicant pool to be named as a Caroline D. Bradley Scholar. He will receive a merit-based scholarship for high school.
MIT Lincoln Laboratory also just named a minor planet after Espen to recognize his achievements. His name will be added to the Minor Planet Center database (run out of the Smithsonian Astrophysical Observatory in Massachusetts). Look out for Minor Planet 34379 Slettnes in the sky!

Espen writes a poem!
BMC student Espen has written a beautiful poem called "My True Number". We wanted to share as it is quite appropriate for the Berkeley Math Circle! Please do not take out the poem without copyright.
My True Number
By Espen Slettnes, Jan 6th, 2014
My shadow and I stood in a complex plane.
"What value are you?" I winked and asked.
"3435i", said he, and he asked me mine.
I said I was 33+44+33+55.
"That's what I am, but times i"he replied.
Our eyes met and danced
as we added and multiplied and exponentiated and tertiated
until we reached the magnitude of beauty,
in the silence of ∞, where I saw my true self.
I spoke no words but the simple language of the universe.
I rose and vaporized into numbers,
integrated with the Universe,
and we became 1.
- The complex plane is a way to represent all complex numbers in 2 dimensions. A complex number is made up of a real and imaginary part.
- i is the imaginary unit, defined as √ -1
- Tertiation is repeated exponentiation, which is repeated multiplication, which is repeated addition.
- ∞ means infinity - larger than any number
- (33+44+33+55) = 3435 (each digit raised to its own power)
