Hi particle physics Twitter — does anyone know of any Ukrainian grad students or postdocs who would benefit from a long-term visit to the US? Thanks in advance.
This is a more technical thread, introducing one of the most beautiful results from Steven Weinberg:
The soft photon theorem
It answers the question why massless spin 1 bosons are associated with conserved charges and why massless spin 2 bosons interact like a graviton 🧵1/19
@coolKidclub___ I think the explanation that's easiest (for me) to understand is based on the "Poinsot ellipse" construction. The three axes below are Lx, Ly, Lz, the three components of the body's angular momentum. Now, the total angular momentum L^2 is conserved, and L^2=const describes

Late to this, but: turns out Erwin Schrödinger sexually abused underage girls. Ugh. He was long known as a bit of a scoundrel, but this is much worse.

ARC reforms are needed, but lack of consultation with the research sector is concerning. Read the statement from @ausphysics here:
