- Chaos & Complex Systems Seminar
- Evolution of intelligence
- Time: 12:05 pm
- Place: 4274 Chamberlin
- Speaker: David Krakauer, Director, Wisconsin Institute for Discovery
- Abstract: In this lecture I shall survey key ideas from the history of mathematics, physics, computation, and biology that have extraordinarily converged on very similar explanations for adaptive or selective behavior. This convergence presents itself in the form of a universal structure in all models describing adaptive search in high dimensional state spaces. I shall describe how intelligent mechanisms, to include nervous systems, evolved to overcome a fundamental limit to the velocity of evolutionary adaptation.
- Host: Sprott
- Theory Seminar (High Energy/Cosmology)
- W+jj: collider physics on the wild frontier
- Time: 4:00 pm
- Place: 5280 Chamberlin Hall
- Speaker: Adam Martin, Fermilab
- Abstract: As data flows in from the LHC, unexpected signals are inevitable. The key question will be: are these 'surprise' signals new physics or do they point to a mis-modeling/misunderstanding of standard model physics? To disentangle the possibilities requires crosstalk between experiment, QCD/Monte Carlo, phenomenology and model building. The W+jj excess observed by CDF last year gave us an example of this process at work. I will elaborate on the efforts to explain this excess -- which remains unresolved -- in the standard model and beyond, and what we should look for at the LHC
