The Dirac equation does not work for more than one electron Updated +Created
TODO understand in detail.
Advanced quantum mechanics by Freeman Dyson (1951) mentions:
A Relativistic Quantum Theory of a Finite Number of Particles is Impossible.
Atom 2007 Mini Series episode 3:
[The Dirac equation] could only describe a single electron. It fails completely to explain what happens when there is more than one electron present. What was needed was a new theory. A theory which explains how electrons interact with each other.
OmniGibson Updated +Created
Reference implementation of the BEHAVIOR Benchmark.
Built on Nvidia Omniverse unfortunately, which appears to be closed source software. Why do these academics do it.
"Gibson" seems to be related to an older project: github.com/StanfordVL/GibsonEnv which explains the name choice:
Gibson environment is named after James J. Gibson, the author of "Ecological Approach to Visual Perception", 1979. "We must perceive in order to move, but we must also move in order to perceive"

The thing was definitely built by researchers. How to cite first, actually working later! And docs are just generally awkward.

BEHAVIOR Benchmark Updated +Created
Quite impressive.
Focuses on daily human tasks around the house.
Models soft-body dynamics, fluid dynamics and object states such as heat/wetness.
TODO are there any sample solutions with their scores? Sample videos would be specially nice. Funny to see how they put so much effort setting up the benchmark but there's not a single solution example.

1954 Nobel Prize in Chemistry Updated +Created
This was almost a two-in-one Nobel for a single dude: both for chemical bond theory and secondary structure theories such as the alpha helix! A beast.

Linus Pauling Updated +Created
The dude was a genius. He went mad later on, but he was a genius, that cannot be debated. He not only founded chemical physics, but then went ton to do structural biology with it.
