https://en.wikipedia.org/wiki/List_of_killings_by_law_enforc... The rate of police killings is vastly higher in the US than any other Western country. So something is going on there that is not a universal phenomenon.

I think that was the point. They are trying to show how that sort of logic is flawed.

"It's not like they're kicking math off of YouTube." Actually, a funny thing happened to me recently that is sort of in this vein. I made a simple app for tuning theory nerds, for examining how a given equal temperament

Ok fair enough. I admit I regret this comment and think I posted it a bit hastily, I tried to delete it a few minutes ago but it appears to be too late now. I edited out the part about dinosaurs though.

1. Carbon dating. Sure, I get that carbon decays over time and this changes the proportion of isotopes. But why does this give you any information? That carbon didn’t come into existence just to be in that bone, it was made in the sun billi

Another way to make it seem more intuitive: "all of these are true" is the same as "none of these are false" (assuming values must be booleans), and clearly nothing in an empty list is false.

I emphatically agree. There is something that walking does to your brain that really helps you see the big picture.

"This is what they already do with their spare time, there's no reason to believe there wouldn't be more of it." I can see one reason: the benefit that you get from an activity is a nonlinear function of how much time yo

Reflecting on this more, my best guess is that you think they are similar because they are both a "grand unified theory of mathematics". To explain the difference extremely briefly then, I'd say it's a massive exaggerati

They are different enough that it's frankly a bit difficult to make sense of that question. I think in general, when asking "what is the difference between X and Y" questions, it helps if you elaborate a bit on why you think

I found it to take much less discipline actually. I find an unstructured and curiosity-driven approach to learning math to be much more enjoyable and effective than the typical school approach. You are right about the solitude issue, althou

This is logically independent from any claim about the value of formal education. I speak from experience that an undergraduate degree is not necessary in order to gain a firm grasp of undergraduate level math. Happy to elaborate if that is

"The usual corollary (that ML should "therefore" be able to learn with a few examples) may only apply, as I see it, if we somehow encode previous "learning" about the problem in very the structure (architecture, har

Are there more recent features of Clojure that you think have made every-pred and some-fn less useful? I'm curious what they are if that is the case.

The argument isn't that we shouldn't colonize other planets because it's expensive, it's that we shouldn't colonize other planets because it's Pareto inferior to making orbital habitats.

Hacker News starts to severely rate-limit replies in deeply nested threads so if you want to continue discussing this you can email me (email in profile). In regards to the question, the latter. The source corresponds roughly to the E vecto

“The question is whether or not you can determine the interconnectedness.” I’m not sure what you mean by this. The algorithm I'm describing doesn't require any data beyond what is already used by PageRank. I have a feeling that yo

"Or is that rephrasing your description?" I think so? There is an obvious circuit equivalent where links are interpreted as one-way resistors. You get a charge potential automatically given the circuit and a choice of source &#x2F

If I may go on a tangent, I’ve thought a bit about the problem of link farms and how it might be addressed. The problem is essentially this: since pagerank is basically the probability that a random walk through the link graph will end up o

You need a convex Lagrangian for the Legendre transform to work so I think it's more than a convention. Of course you could redefine the Legendre transform to work for concave functions instead of convex functions but in either case yo

"or maximizing" The critical points of the action are either local minima or saddle points, never maxima.

Also, a simple example of the action being a saddle point: a moving object constrained to the surface of a sphere, with no potential, which will move around a great circle.

> Strictly, realizable paths are an extremum (maximum, minimum, or inflection point) of the action. At a realizable path, the action can be a local minimum or a saddle point but it's never a local maximum. Tangentially, while "

Yeah I checked that too. It's puzzling as I am 100% certain it's older than 2007.

edit: weirdly the parent comment of my comment has disappeared and now my comment has been moved to a top level comment and appears to be apropos of nothing. Oh well. I'm pretty sure this predated the programming language. I can't

I think Portland is pretty temperate compared to Mongolia, where such dwellings are traditional. Also, they better insulated than the mobile kind of tent and therefore are not Pareto-inferior.
