Meet the Platonic Solids: Octahedron


The Platonic solids have been known since antiquity, and they play a prominent role in Plato's description of the physical world. The planar faces of each solid are identical polygons. Only equilateral triangles, squares and regular pentagons appear.

Although the platonic solids seem to be purely geometric objects, they embody a number of deep algebraic features. Their symmetries, for example, relate to the solution of polynomial equations of low degree.

Click here for some very comprehensive guidelines for continuing your education and really great advice for those interested in pursuing a PhD in mathematics.

Undergraduate Lecture Series:

The Math Department is organizing a student seminar designed to have faculty present accessible lectures to start conversations on advanced mathematics. These talks will be accessible to undergraduate students and cover a wide range of topics. For the Fall 2017 semester, we will meet generally in NAC 4/108 from 1:00PM-2:00PM on Thursdays unless stated otherwise. For more information, please check out the seminar website or join the Google group to be notified!

Tea Time:

Every Tuesday 1:00 PM The Math Club and [A.W.M.] meets in 6/270 for an afternoon tea to discuss the 'finer' things in life, and gripe about our classes.

Past Events:

In 1736, Euler was given a problem to which he said there is no solution. This problem laid the foundations of graph theory and prefigured the idea oftopology. We willtalk aboutthis problem and why it was so significant along with some fun explorations into the world of graph theory!
