I guess my point is that, since most people find the math hard, writers put history in as what appears to be filler, which I find as mostly an obstacle.

As a mathematician, I disagree, but this is probably because I already understand the math pretty well. I'd much rather have a clear picture of the most useful mathematical models for the various areas of physics (and where they fail)

I actually spoke with a person who works with a specific convict who wants to learn math and programming. They apparently ran into this problem. I don't have a reference, though.

In addition to spam/abuse and the difficulty of setting up a server, another area of centralization that hasn't yet been solved is payments. If we want a truly decentralized web, we need a way for computers to posses and spend mon

As an interesting side note, it turns out books on programming that include chapters on encryption are not allowed in prisons.

My cousin's five year old daughter loved this book. Learned what prime numbers are :)

Indeed, the Monte Carlo post was inspired by some discussions after reading that chapter. I also borrowed and adapted a proof or two from the SVD chapter for that second post.

I don't meditate, actually, I was just including that in re some other thread that was mentioning it. I'm saying that yes, Chess does improve strategic thinking skills, but it probably won't help you be more strategic in othe

My wife teaches math at a community college level, meaning she often needs to teach students who are paralyzed by fear of fractions (or worse, negative numbers). Many of her students are also adults. She tells me things like "If I ask

Ignoring your derisive tone, the statement "most people get through their daily lives just fine without it" applies to every new technology. Yet here we are, typing away on the internet.

Why does everyone (including the director of the NSA) get away with lying to Congress?

IIRC there were on the order of ten attempted replications, all of which failed.

Is this why my computer screen's brightness controls always seem to have a huge jump between the lowest two settings (off and dimmest-before-off)?

I updated it to be simpler, but to be fair there is a preface to that paragraph saying "for long-time readers of this blog" to remind them of some of the details of a related previous post.

> drawing x with probability p(x) given p(x) for every x in finite set X sounds pretty trivial thing to program w/o knowing anything about Markov chains and stuff Then you misunderstood the complexity of the problem. It's okay,

Interestingly, according to Wikipedia the SIGSALY was in production before Koenig "invented" the technique. And according to the one-time pad page, one-time pad was first theoretically invented in 1882 by Frank Miller https:&#x2F

Let's suppose that there actually were a proposed quantitative measurement system for art. I'd try to make a piece of art that scores the lowest possible.
