The easiest is to look at characteristic functions and cumulants; for a random variable T with PDF p(t) we say T ~ p and define φ_T[f] = ∫ dt p(t) exp(-2πift) = ⟨ exp(-2πifT) ⟩ If two variables X ~ r and Y ~ s are independent then you can p

This might be suitable. I don't know about jlv2, but the Dutch frequently have a tussenvoegsel [1], an insertion between their names which is properly lowercased but is a part of the family name. So the physicist who researched molecu

There is, but it’s hard—like, theoretically murky hard. So the basic inefficiency is that you want to do top-down resource allocation, “I approve of this much budget going to that project.” We could call that bureaucracy, or The State, or w

I once was outlining notes for a course I would like to give introducing computer programming. The idea was to have exercise and theory sessions interleaved, which left the first session, which has to be theoretical in order to introduce th

Oh wow. I was really not expecting you to join this conversation and I am very thankful to have crossed paths with you, even so briefly. Sorry for getting you wrong about the “objects” vs. “OOP” thing. I have thought you could maybe call it

I don't believe he claims to, no. He coined the term “object,” but what he meant by a computational object was different than what it came to mean: a data structure with associated operations upon it. Kay meant a parallel thread of exe

Yes, the event horizon of a black hole is precisely this sort of wall of death. Indeed there is an active debate in the literature about whether outside observers ever see black holes because from the outside perspective infalling mass shou

Sort of, not quite. The basic background is that Einstein wrote a paper taking Lorentz more seriously than Lorentz took his own work: and that paper suggested that just maybe, when you accelerate in any given direction by an acceleration A

This is just one of those solutions that was beautiful and simple and why didn't we think of that. The goal of distributed consensus can be viewed as something to do with creating a transitive order A < B < C < D out of indivi

Sure, but my physicist training requires me to add the standard caveat about sample size of 1. Depression comes in many forms and what works for me and my form of depression may not work for yours. In addition there is some research that su

Wow. One would generally not consider exceptions part of a public API but I suppose they really are; if one rewrites it as a sort of Haskell-ish `Input -> Either Error value` one can see this directly... then if one church-encodes one al

You are not, on present definitions. This is one of those things that a lot of members of the public at large do not seem to know; they think that depression is defined as some sort of chemical imbalance in the brain, and it is not. Depress

Thank you for your kind words!

So like it wouldn't be a decay if it went neutron → neutron, if that makes sense. There is one “main” diagram which goes neutron → neutron and it looks like a straight line with no vertices and it is by far the most probable thing, mos

So we have these matter particles that are defined by three numbers, a weak hypercharge Y in the set {1, 1/3, -1/3, -1}, a weak isospin T in the set {1/2, -1/2}, and a ‘generation’ in the set {0, 1, 2}. The electric cha

This is a good question and I have been at multiple shops which had this bug induced by a "let's just log everything" accident somewhere in the codebase. It's very nice to think of logging as a sort of "aspect"

Not quite. A Clojure transducer from A to B is pure function which takes As to lists of Bs. To apply it to a sequence of As you flatMap it, so you apply it to each A in sequence and get a sequence of Bs which you splice into your final res

So a country called Greece which had been a part of the EU had a severe financial collapse a year or two (2009ish?) after the period when (2007-2008) the US had a subprime mortgage collapse that triggered the collapse of Lehman Brothers, th

Ask more questions. You got like one little answer about this but this is like general life hacking, tied to an axiom from salesfolk you might’ve never heard before, “Tellin’ ain’t sellin’.” You never, in other words, start talking to a n

Given the implementation, an interesting way to cheat is to use the following "never loses" sequence: RRRRRRLRRRLRLRLLRRRRLLRRLRRLRLLLRRRLLLRLRRLLRLRL RRRRRRLRRRLRLRLLRLLRRRRLLRRLLLLRRLRRLRLLLLLRLLLRRRLLLRLRRLLRLRL R

Please notice that the payoffs in this program are set up such that you will, in fact, feel cheated. The basis for this is that you will likely spend maybe 30-60s playing this game so you will register something between 100-200 keypresses o

I never would say something is impossible to believe unless it were a logical contradiction, and even then I wouldn't be 100% sure in saying it. People believe all sorts of things. I’m just saying that people have a right to be disgust

I mean if you're curious there actually is a good argument for not buying the homeless food, and it has to do with a sort of "market saturation." Talking to some homeless people and some formerly-homeless people, my understan

I mean, to put it bluntly, yes. You might not be disgusted, that is your right. It is their right to be disgusted. If you're looking for an argument why one should be disgusted, one cannot be forthcoming. I cannot give you a very per

At first the numbers shocked me (500k books, 16 reviewers) because they entail something like ~100 books added per reviewer per day (~250 workdays/year, 2k books per workday). Then I saw the numbers of copies ordered for the top 10 tit

I think the problem is a tension between what’s valuable to us in learning and what's valuable to us after learning. So when I was tutoring, I noticed that my “standard approach” failed: a kid would have a homework problem, I would say

Now that is an interesting story that I have not seen anywhere. So if I'm understanding you right, this danger to bees is a sort of hack where our business-needs (namely being able to control what we pollinate and when) cause us to t

Example of the arrogance mentioned in the first point: I have met folks who have seriously argued to me that their code contained no technical debt because "We wrote it right the first time." The code at the time was something in
