Colloquium MathAlp 2019 - Claude Lebrun
Claude Lebrun - Mass, Scalar Curvature, Kähler Geometry, and All That Given a complete Riemannian manifold that looks enough like Euclidean space at infinity, physicists have defined a quantity called the “mass” that measures the asymptotic deviation of the geometry from the Euclidean mod

Claude LeBrun - Yamabe invariants, Weyl curvature, and the differential topology of 4-manifolds
The behavior of the Yamabe invariant, as defined in Bernd Ammann’s previous lecture, differs strangely in dimension 4 from what is seen in any other dimension. These peculiarities not only manifest themselves in the context of the usual scalar curvature, but also occur in connection with

Lionel Mason - Perturbative formulae for scattering of gravitational wave
The Christodoulou‐Klainerman proof of existence of asymptotically simple space‐times shows that it is reasonable to consider the scattering of characteristic data for the Einstein field equations from past null infinity to that on future null infinity in a neighbourhood of Minkowski spac

You Don't Know How Mirrors Work
Mirrors are weird. To truly understand them, we'll need not only ray and wave optics, but also photons, wave functions, probability, and quantum mechanics. Brilliant for 20% off: https://brilliant.org/ScienceAsylum ________________________________ VIDEO ANNOTATIONS/CARDS Quantum Wave Fun

Lionel Mason (University of Oxford) - From Twistors to Gravitational Scattering (1/2)
This lecture will review how linear gravity can be obtained from integral formulae from twistor space and how the fully nonlinear self dual sector of 4d gravity can be built using complex analysis. It will focus on global problems in split signature where the self-dual sector can be genera
