Mathematical Biology seminar: "Automated Feature Extraction from Large Cardiac Electrophysiological Data Sets"

Peter Hinow (University of Wisconsin-Milwaukee)
- See Zoom link

A multi-electrode array-based application for the long-term recording of action potentials from electrogenic cells makes possible exciting cardiac electrophysiology studies in health…



High Energy Theory Seminar: Compact dimensions: how many and how small?

Thomas Van Riet (Leuven University)
-

I will discuss the rather striking situation that confronts us in the context of conventional string phenomenology: 3 spatial dimensions are of Hubble size and 6 other ones are of sizes much smaller than…



Astronomy Seminar: Astronomy in the Era of Mega-constellations of Low Earth Orbiting Satellites

Tony Tyson (UC Davis)
-

A number of companies and governments are in various stages of planning or deploying bright satellites in low-Earth orbit in unprecedentedly 



Mathematical Biology seminar: "Stochastic Modeling of Reaction-Diffusion Processes in Biology"

Hye-Won Kang (University of Maryland Baltimore County)
- See Zoom link

Inherent fluctuations may play an important role in biochemical and biophysical systems when the system involves some species with low copy numbers. This talk will present the recent work on the…



Mathematical Biology seminar: "Fluid mechanics of the respiratory system and active coating materials"

Arnold Mathijssen (University of Pennsylvania)
-

Our airways are continuously exposed to potentially harmful particles like dust and viruses. The first line of defence against these pathogens is a network of…



High Energy Theory Seminar: Sphere packing, gravity, and the conformal bootstrap

Tom Hartman (Cornell University)
-

I will describe recent progress on the connections between three topics: conformal field theory, the sphere packing problem, and quantum gravity in three dimensions. The link is provided by a technique…



Physics and Astronomy Colloquium: “The String Landscape and the Swampland"

Cumrun Vafa (Harvard University)
- NOTE: FROM NOW ON, ALL COLLOQUIA WILL BEGIN AT 3:00 PM!

String theory landscape of vacua point to new consistency conditions that a quantum gravitational system must satisfy.  There are only a small number of quantum field theories that satisfy these…



Thesis Defense: “Exploring relationships between structure, dynamics, and the effects of local perturbations in networks"

Lia Papadopoulos (University of Pennsylvania)
-

Committee: Danielle S. Bassett (primary supervisor), Randall Kamien (chair), Eleni Katifori, Victor Preciado, Mirjam Cvetic



Primakoff Lecture: “The Life and Death of Turbulence”

Nigel Goldenfeld (University of Illinois – Urbana Champaign)
- Zoom

Turbulence is the last great unsolved problem of classical physics. But there is no consensus on what it would mean to actually solve this problem. In this colloquium, I propose that turbulence is most…
