He usually explains the details right after stating it. For example, you can follow along in his lecture notes: https://www.scottaaronson.com/democritus/lec9.html . "Statistics but with the 2 norm" is really

In Scott Aaronson's paraphrased words... Quantum mechanics is just statistics, but operations preserve the 2-norm instead of the 1-norm. Instead of case weights (probabilities) adding up to 1, the squares of case weights (amplitudes) a

It's statistics but instead of operations preserving the 1-norm (item weights [probabilities] add up to 1) they preserve the 2-norm (squared item weights [amplitudes] add up to 1). Instead of using stochastic matrices you use unitary m

Even accounting for the uncertainty principle, the amount of information you can transfer in principle with a single photon is far more than one bit. For example, you can distinguish the single photon hitting a screen at more than two diffe

In hardware this would be called a carry save adder [1]. One interesting fact about carry save adders is that the carry part of the register can be extended in order to avoid any carrying between words for very long periods of time. Instead

I wonder if there's an analogy between a schizophrenic looking at reality and a savy movie goer looking at a movie. There's certainly something a bit deranged to "movie logic". This random object can't be for nothi

It depends on your overall strategy. If you want everyone to get the disease but at a rate that hospitals can handle, then hospital capacity vs case count will be a very important piece of data for making decisions. If you want to control t

Right, but if I go closer to the metal how much of the latency is really truly intractable? 100 microseconds? 1 millisecond? 10 milliseconds?

What is a reasonable lower limit on latency that I could expect from a GPU pipeline? For example, I know that if I use WebGL and issue a `readPixels` call then that seems to take on the order of 1 to 10 milliseconds no matter what I do. Thi

Bayesian inference applies to quantum mechanics in the "obvious" way. You have some hypothesis space (of possible wavefunctions). You plan to perform an observation (a measurement). Different hypotheses assign different probabilit

In my experience, it's even a bad idea to share immutable data between tests. At least, certain types. Basically what happens is you write a bunch of tests, and they all operate on a Person let's say. So you get into the habit o

To rant a bit more about this one second delay thing. This reeks of a type of thinking where you are relying on other parts of the system to compensate. You might expect to hear things like "it's okay, the safety driver will catch
