Expanding Your Horizons Returns to UK - Saturday, April 21, 2018

STEMCats Living Learning Program

STEMCats, sponsored by HHMI, is designed to help students succeed at UK. The program prepares students both academically and socially through participation in FastTrack or FOCUS, research opportunities, and special seminar courses. Students participating in STEMCats will build confidence, enthusiasm, satisfaction and a sense of belonging to UK, and experience a smoother transition to college coursework. This leads to improved performance and higher academic achievement.

Renovated Mathskeller Open House Rescheduled for This Wednesday

Many agree that an environment can shape the learner, and in a field like mathematics, an environment that fosters active learning and engaged teaching with no appointment necessary may be the key to success for some students.

Prominent Female Mathematician to Deliver van Winter Memorial Lecture

The 2012 Van Winter Memorial Lecture: Paul Steinhardt and Quasicrystals

Each year, the Department of Mathematics and the Department of Physics and Astronomy jointly organize the Van Winter Memorial Lecture, which brings in distinguished speakers to give lectures on matters of common interest to mathematicians and physicists.

This year's speaker is Paul Steinhardt, professor of physics and astrophysics at Princeton University, and director of the Princeton Center for Theoretical Sciences. In this podcast, we spoke to Sumit Das, who will be hosting the lecture, about some of professor Steinhardt's research.

Professor Steinhardt's lecture will be titled, "Once Upon a Time in Kamchatka: the Extraordinary Search for Natural Quasicrystals." The presentation will be on Friday, March 23, from 3:15 pm to 4:15 pm, in room 139 of the Chemistry-Physics building.

In short, a quasicrystal is a type of structure that shows rotational symmetry, but is not periodic -- it doesn't have a pattern that repeats over a distance. Quasicrystals can be composed of sets of a few shapes that are arranged to fill up a space, and although they may have radial patterns, these do not repeat around the crystal in any noticeable order. Usually, it has been thought that crystals can only have two-, four-, or six-sided radial patterns, but quasicrystals can have five-sided rotational symmetry as well, such as in these structures:
