Mathematical Biology seminar: “Water Dynamics in Cells and Tissues"

Sean Sun (Johns Hopkins University)
- Tedori Family Auditorium, Levin Building, 425 S University Ave.

The mammalian cell surface is highly permeable to water. The cell can also actively control the water flux across the cell surface by pumping solutes (mostly ions), and thereby controlling the cell water…



Special High Energy Theory seminar: "Conformal Inversion of Extremal Black Holes, and Aretakis and Newman-Penrose Charges"

Chris Pope (Texas A&M University)
- David Rittenhouse Laboratory, 4N12

The extremal Reissener-Nordstrom metric is invariant under an inversion of the radial coordinates, combined with a conformal rescaling.  This implies that conserved Aretakis charges, defined on the…



Physics and Astronomy Colloquium: "Finding Other Earths – New Frontiers in Exoplanet Science with Next-Generation Doppler Spectrometers"

Cullen Blake (University of Pennsylvania)
- David Rittenhouse Laboratory, A8

The Doppler technique is a key tool for discovering and characterizing planets orbiting other stars. By measuring periodic shifts in stellar…



Knowledge by the Slice lunchtime series: "Finding the First Stars and Galaxies (by Looking Where They Aren’t"

James Aguirre (University of Pennsylvania)
- Cafe 58, Irvine Auditorium, 3501 Spruce Street, Philadelphia

Our current understanding of the universe starts with a Big Bang 13.7 billion years ago that created a simple,…



Joint High Energy Theory/Experiment seminar

Patrick Meade
- Location TBA



Physics and Astronomy Colloquium: "Top Down Approach to Quantum Fields"

Jonathan Heckman (University of Pennsylvania)
- David Rittenhouse Laboratory, A8

Quantum Field Theory (QFT) is the common language of particle physicists, cosmologists, and condensed matter physicists. Even so, many fundamental aspects of QFT remain poorly…
