I can think of a font that’s only 1 pixel high. Invented by Samuel Morse, takes a bit of practice to read :)

HMC was essentially designed to mix random walks (the momentum refresh step) with gradient descent (that is, the state likes to 'roll down the potential' ie. minimize the action (loss)).

There are many equivalent formulations of quantum mechanics, the one the above post takes issue with is the path integral formulation. But because you can show an exact mathematical equivalence it makes all the same predictions as, for exa

Many years ago [1] I was led to a marvelous site explaining many subtleties of human color perception, including the three cone primaries. The author called this pure-M-cone response "psychedelic aquamarine"; the page is offline

The standard model has ~20 parameters (depending on what exactly you include as 'the' SM) and it predicts hundreds of thousands of data points.

Jacobson showed that thermodynamics + special relativity = GR. Those are very very general assumptions, so general that it’s hard to even consider what else you might ask for.

The real bug being addressed is not a technical bug but a societal and cultural bug. Writing the 0 in front is a reminder that the present moment is just the beginning and that behavior that benefits us in the short term may cause proble

As I mention in a response to a sibling post, it's really about the broader lesson of long-term thinking about the far future.

You're right; this is nothing to do with spooky action at a distance. But sympathetic response, or resonance, is how this device would work---just like a radio. Axions couple to electromagnetism; by listening in on different frequenci
