Simulating a Wigner crystals with path integrals was one of the first things I tried in grad school. Very cool for me to see them realized.
Physicists have tried to form a “Wigner crystal” made from electrons for decades. Last month, two independent teams of researchers reported the most direct experimental observations of Wigner crystals yet. @Ironmely@twitter.com reports: https://www.quantamagazine.org/physicists-create-a-bizarre-wigner-crystal-made-purely-of-electrons-20210812/

Good thread on Delta. https://twitter.com/WilliamBHoenig/status/1416430672948903937
I make fun of places adding back light-weight NPIs with a history of failing. The reality is that masks won't stop the train to 100% seroconversion, but they do have real costs (bars / clubs / music can't functionally operate with masks; return to office just won't happen). 26/n
In this world, the meaning of endemic Covid is that most of the vaccinated will be infected by SARS-CoV-2 at some point. For most of us that will be a cold. For those who don't seroconvert from the vaccine it could be a worse threat. 19/n

How does perception of objects arise? Objects undergo huge changes in appearance due to deformation, perspective change, & dynamic occlusion. We prove from first principles that it’s possible, without learning, to perceive invariant objects despite this. http://arxiv.org/abs/2107.02036
