Also my experience. Academic culture benefits immensely from terrific people at the top. To put it more bluntly "Dave Wineland is super nice. Why do you think you can be a <insert favorite expletive here for someone who is a pain to work with >?"
My Ph.D. advisor was Bill Phillips, who's a terrific person. Alain Aspect, Claude Cohen-Tannoudji, Eric Cornell, Jean Dalibard, Wolfgang Ketterle, Dan Kleppner (RIP), Norman Ramsey (RIP), and Dave Wineland were also great whenever I interacted with them. AMO physics is full of good folks.
Right, enough of James Watson - who's a senior academic you've met who's been an utter delight?

Aside from Yang-Mills theory and parity nonconservation, Yang made so many profound contributions to physics! One that deeply impressed me as I was starting grad school: a 1975 paper with T. T. Wu highlighting the role of fiber bundles in gauge theory.

A little treat going into the weekend: the midterm for my quantum mechanics class was a couple weeks ago, and again the students made memes for extra credit.
Let's start out strong with a PSA about the dangers of nondegenerate perturbation theory. Do you know where your good states are?

Fault-tolerant logical measurement just got a lot faster!
In new work, we show that code surgeries based on hypergraphs, rather than graphs, allow fast and parallel fault-tolerant logical measurements with low qubit overhead (without requiring the code to be single-shot).
