- Chaos & Complex Systems Seminar
- Living the unknown: A dancer's perspective
- Time: 12:05 pm
- Place: 5310 Chamberlin (Refreshments will be served)
- Speaker: Choi Myo-Young, UW Department of Dance
- Abstract: In these times of economic chaos, social turmoil, we live with a sense of growing insecurity about the future. Through the lens of dance, we can look to the past--both mythic and real--as a means to fearlessly face our future.
- Astronomy Colloquium
- The Ins and Outs of Stellar Oscillations
- Time: 3:30 pm - 5:00 pm
- Place: 3425 Sterling Hall
- Speaker: Richard Townsend, UW Astronomy Dept
- Abstract: Once thought to be a peculiarity exhibited by a minority of stars, stellar oscillations are now regarded as the rule rather than the exception. Across the whole Hertzsprung-Russell diagram, we see evidence of the periodic photospheric motions that are the hallmark of the excitation of one or more oscillation modes. In this review talk, I'll discuss the wave properties of these modes; explore the various mechanisms for their excitation; explain how they can be used to probe the internal structure of stars, through the discipline of asteroseismology; and, consider how oscillation modes might alter this internal structure.
- String Theory Seminar
- String Universality in Six Dimensions
- Time: 4:00 pm
- Place: 2301 Sterling Hall
- Speaker: Vijay Kumar, MIT
- Host: Gary Shiu
