What Is Global History? A Roundtable

February 20, 2020
Since its publication in 2016, Sebastian Conrad's What Is Global History? (Princeton University Press, 2016) has been read and debated not only by historians of modern Europe but also by historians of different parts of the world and scholars in different disciplines.

Who writes global history? How and for whom? And why now?

Bring your questions and thoughts, and join the conversation.

An Effective Field Theory of Quantum Black Hole Horizons

Walter Goldberger

February 10, 2020
I develop an effective theory which describes black holes with quantum
mechanical horizons that is valid at scales long compared to the
Schwarzschild radius but short compared to the lifetime of the black
hole. The formalism allows one to calculate the quantum mechanical
effects in scattering processes involving black hole asymptotic states.
The EFT Wightman functions which describe Hawking radiation in the Unruh
vacuum are not Planck suppressed and are actually enhanced relative to
