Mathematical Biology seminar: "Opinion Dynamics with Tunable Sensitivity: Consensus, Dissensus, and Cascades"
Naomi Leonard (Princeton University)
I will present a general model of continuous-time opinion dynamics for an arbitrary number of agents that sense or communicate over a network and form real-valued opinions about an arbitrary…
High Energy Theory Seminar: Closed strings and weak gravity condition from higher-spin causality
Sandipan Kundu (Johns Hopkins University)
I will show that metastable higher spin particles, free or interacting, cannot couple to gravity while preserving causality unless there exist higher spin states in the gravitational…
Condensed and Living Matter Seminar: "Tiny Robots"
Mark Miskin (University of Pennsylvania)
After 50 years of Moore’s law, it’s now possible to pack nearly 1 million transistors in the space of a paramecium, enabling tiny systems for sensing, communication, and computation. This radical miniaturization of…

Mathematical Biology seminar: "Dynamics of movement in complex environments"
Sarah Olson (Worcester Polytechnic Institute)
In this talk, we will highlight two different types of movement in viscosity dominated environments: sperm navigation and centrosome clustering in dividing cells. Sperm often interact with chemicals and…
High Energy Theory Seminar: Entropy and symmetry in QFT
Javier Magán (University of Pennsylvania)
We describe a novel approach to gauge and generalized symmetries in QFT. It starts with the analysis of fundamental properties (additivity and Haag duality) that appear in the '…
Condensed and Living Matter Seminar: "Curious Electrostatics in Concentrated Electrolytes"
Susan Perkin (Physical & Theoretical Chemistry Laboratory, Oxford University)
An electrolyte is a substance containing mobile ions. Electrolytes are within us and surround us at every scale: they mediate molecular processes in all living systems, they fill the phone batteries in our pockets,…
Astronomy Seminar: Cosmology and Astrophysics with Intensity Mapping
Yun-Ting Cheng (Caltech)
Intensity mapping has emerged as a promising tool to probe the high-redshift universe by measuring the aggregate emission without resolving individual sources, complementing the information from…
