Reaching Out To Prospective Wildcats: A&S Ambassador Charlie Fieseler

Charlie Fieseler is an undergraduate student majoring in Physics and Mathematics. Charlie is also a member of A&S Ambassadors, a team of undergraduate students that visit neighboring grade schools to discuss what it's like to be a UK student. In this podcast, Cheyenne Hohman sat down Charlie Fieseler to discuss his personal experiences with the Ambassador program.

The Formation and Evolution of Galaxies Group: Isaac Shlosman

At UK, the Formation and Evolution of Galaxies Group is a team of graduate students, post-doctoral fellows, and faculty, who use the University's Dell Cluster supercomputer to predict and simulate the galactic mechanics of the early universe.

In this podcast, we talk to Isaac Shlosman, the group's faculty lead, about an observational discovery made in the fall of 2011, what will replace the Hubble, and how dark matter forms the back-bone of the universe.

Ganpathy Murthy, Professor of Physics and Astronomy, speaks about Big Bang Theory, Dark Matter and Dark Energy. Part 3 - More Evidence, Including the Evidence for Dark Matter, and Dark Energy More on the Big Bang, how we measure how far away different parts of the universe are Dark Matter, Dark Energy

What's New in Science - Ganpathy Murthy Part 2

Ganpathy Murthy, Professor of Physics and Astronomy, speaks about Big Bang Theory, Dark Matter and Dark Energy. Part 2 - What’s the Evidence for the Big Bang and Expansion of the Universe? What Do We Measure and How? What’s the evidence? How we know the Big Bang happened, and that the universe is expanding and accelerating. How we measure how fast different parts of the Universe are moving away.

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:

In part two of the Dean's interview with Mike Cavagnero, the Chair of Physics and Astronomy discusses the role of the department on campus and the possibilities and excitement of where the discipline may be headed.

Dean's Channel: Mike Cavagnero Helps Students Measure Science

Mike Cavagnero, the Chair of the Department of Physics and Astronomy, was one of the initial faculty members to teach a class in A&S Wired in Fall of 2011 titled Measuring Science. He talks about the course and the power of using the iPad in the classroom. You can also view a video on the final projects the class did: vimeo.com/35279096 This is part one of a two-part Dean's Channel interview with Mike Cavagnero. Part two is here - vimeo.com/35011430
