Michael Hutching | BMC-Upper Colloquium Dec 11, Sunday, 3-4PM Speaker: Professor Michael Hutching Chair of the Mathematics Department UC Berkeley
Title: The mathematics of Rubik's cube Abstract: We will discuss the group theory related to Rubik's cube. By the end of this talk you should be able to solve Rubik's cube, possibly taking a while, but understanding every step. The same ideas can also be used to solve other similar puzzles (larger cubes, other polyhedra, etc.). You are encouraged to bring a cube to experiment with if you have one, and we will also have some cubes available.

Espen Slettnes | BMC-Upper Colloquium
Title: Magical Proofs
Abstract: Through gaining experience in math research and olympiads, one develops a sense for how to generally approach different types of problems, building a repertoire of problem-solving tricks and techniques that can be used to tackle them. Then there are *those* problems — the ones that defy the rules of composition that most other problems are subject to, whose solutions seem to stretch the limits of what’s possible. This talk is a tribute to these magical problems, demonstrating how these seemingly impossible puzzles can transform into feats of ingenuity.
Speaker Bio: Espen Slettnes joined the Berkeley Math Circle in Spring 2012, where in more recent years, he has served as an instructor for the Advanced Group and as a grader, problem writer, and coordinator for the proof-based monthly contests. He earned a gold award at the 2022 USA Mathematical Olympiad (USAMO) and attended the national Mathematical Olympiad Program (MOP) twice. Espen is a published math researcher who began his research journey in 6th grade; the following year he started interning at the MIT PRIMES-USA research program for several years, completing various individual and group projects in combinatorics. He received the Spirit of Ramanujan Fellowship thrice in 2018, 2019, and 2020. His work has been recognized by the Broadcom MASTERS national science fair, the Shing-Tung Yau High School Science Award, Davidson Fellows, the MAA Outstanding Presentation Award at the Joint Mathematics Meetings (JMM), etc. In recognition of his achievements, minor planet 34379, discovered by MIT Lincoln Laboratory in 2000, was named “Slettnes" in his honor. |
