We are dedicated to making mathematics accessible and fun to all Cornell students, and to enhancing the experience of undergraduate math study.

We organize:

We organize:

- Various talks given by Cornell students and faculty
- Weekly meetings in Mallot 5th Floor Lounge (Mallot 532) 6pm on Thursdays consisting of puzzles or game sessions, always with pizza.
- Annual Kieval Lectures delivered by prominent mathematicians from other institutions.
- An ads page here. I am pretty sure we do not sell your data to google but there's no way to know for sure. Contact the webmaster to purchase an ad spot on this page.
- A compilation of online resources on this site.
- Other miscellanious mathy undergraduaty events.

Given a commutative ring R, we can define the unitary Cayley graph of R as the graph with vertices labeled by the elements of R, with x adjacent to y if and ony if x-y is a unit in R. These graphs are full of symmetry and structure-which often makes computing graph parameters for them quite nice. We will talk about why these graphs are important, investigate some connections to number theory, and then play around with various graph parameters. This talk should require no background to understand and will end with some fun problems to try.# Math Club Talk

In 2001, we had a breakthrough: Shors algorithm was used to factor 15 in polynomial time. We will begin with a brief rundown of the mathematics involvded in quantum computation, such as qubits and entanglement, and see why linear algebra lets us have our cake and eat it too. The talk will focus on the construction of several quantum logic gates, such as the Toffoli and Hadamard gates, which we will leverage to prove that quantum circuits are actually capable of faster computation than classical ones. If time permits, we willhopefully get to an overview of Shors algorithm.# Math Club Talk

A falling cat tends to land on its feet, if given enough time, even for non-upright, non-rotating initial conditions. This poses an apparent paradox. The cat has access to no external torques, and therefore angular momentum is conserved and zero during the cats fall. How can the cat flip itself over?
