- Chaos & Complex Systems Seminar
- The textual structure of REM dreaming
- Time: 12:05 pm
- Place: 4274 Chamberlin (refreshments will be served)
- Speaker: Art Schmaltz, Prairie State College
- Abstract: The human brain during REM dreaming is a singular neurological event that may well be the most complex event known to science. As a biologically evolved system, dreaming long predates the evolution of human language.<br>
<br>
In this presentation, I will parse out one of the ten lines of evidence that argues that human language evolved "down" from the complexity of dreaming, and not "up" from a simpler biological system. - Host: Sprott
- WIPAC Seminar
- Ultra-high energy neutrino events at the IceCube and the Glashow resonance
- Time: 4:00 pm
- Place: 5280 Chamberlin
- Speaker: Atri Bhattacharya, Harish-Chandra Research Institute, Allahabad, India
- Abstract: The Glashow resonance is a peak of enhanced cross-section for an electron-anti-neutrino of 6.3 PeV energy interacting with an electron and producing a resonant W boson, which further decays into electrons and hadrons producing cascades in a large volume (Km^3) neutrino detector such as the IceCube. We will explore the significance of this narrow bin of energy, generally with respect to ultra-high energy events in the IceCube, and particularly, in view of the two recently observed neutrino events at the PeV energies; we will show that the observation of (or lack of) events at 6.3 PeV energies in the future will allow us to understand several facets of the Ultra-high energy neutrino flux coming, possibly, from extra-galactic sources.
