I have been simulating fluids for 15 years.
There is a widespread impression that the Navier Stokes equations have been now “solved”, thanks to OpenAI.
This suggests that they were “unsolved” so far and this was a major engineering breakthrough.
This is not true. This misunderstanding deeply bothers me as a computational physicist.
So I had to put this out.
"We didn’t work on (1) time travel, (2) teleportation, and (3) antigravity. They are not important problems because we do not have an attack. It’s not the consequence that makes a problem important, it is that you have a reasonable attack. That is what makes a problem important"
I remember I read a book once in high school by Barbara Oakley on how to do math, and she said you should focus hard on a specific problem and then take a break to let your brain enter a “diffusion mode” where the latent space is explored 🤔
TIL that perplexity is just entropy exponentiated.
So entropy measures the average bits while perplexity gives the raw number of combinations (2^ave_num_bits)
@___Harald___ Yeah same. Sometimes it’s a lot of fun but sometimes I feel like it gets out of hand and all of sudden you have so much code and you have no intuition for how it connects and works. I don’t like that feeling :/
