Matrices are linear maps, and matrix multiplication composes the linear maps. Now statements like the determinant of the product is the product of the determinants, the trace is preserved under similarity transforms (since similarity transf

The best explanation is probably that squared error gives you the best fit when you assume your errors should normally distributed. Things like the fact that squared error is differentiable are actually irrelevant - if the best model is not

The difference between this and the Iphone 1 is that the technology is not there yet for fully autonomous cars, and it's unclear you can get there just by trying really hard and spending lots of money. Fully self-driving cars wouldn&#x

For coding specifically, I find that I procrastinate much less when I'm debugging. Having the compiler give me bite-sized, well-defined tasks to complete can be very good for morale. So I try to avoid writing code for more than an hour

Thiel might have ulterior motives, but his support of Trump is not too surprising if you've listened to his other ideas. He feels that the political agenda has been overrun by distractions, like "who can use which bathroom",

The idea of using neural networks to do what humans can already write code to do seems a bit wrong-headed. Why would you take a system that's human-readable, fast, and easy to edit, and make it slow, opaque, and very hard to edit? The

I'm a bit worried that OpenAI hasn't released anything substantive for the past four months. There are research ideas like this one, but most ideas don't pan out. With the number and quality of people they have, I would expec

F# is Microsoft's rendition of OCaml. It's super nice if you're trapped in the .Net world, where the alternatives are C# and Visual Basic. Otherwise it suffers from the same lack of open source infrastructure and good non-Win

Maybe the improvements in the weight of the shoe matter, not just the spikes. Reducing the weight is more than a matter of shaping the shoe - I think most improvements now come from using new materials. The weight is added at an extremity a

Longevity research is interesting because you could theoretically get to a point where one year of research extends people's lives more than one year. Then the people who avoided car accidents and the flu could live indefinitely, which

"It's a shame that comparing politicians and their actions to Hitler has became a cliche everyone now is quick to ignore." The trouble is that whenever person Y puts person X and Hitler in the same sentence, there will be new

Yes, exactly. When I hear people brag about how functional languages don't allow side effects, I always wonder, what's to stop you from just writing your program without side effects in an imperative language? And occasionally it

Shallow criticisms of string theory usually miss how difficult it is to come up with physical theories that don't lead to some kind of contradiction. For this reason, lots of new physics has been discovered by looking at mathematical c

I don't consider the example you gave to be a coincidence, because if you know the definition of e then you know why one of those numbers could line up really, really well with e. I'm basically saying that Feynman's argument

Well, Feynman is assuming that x^n + y^n is as likely as any other number to be an nth power. He shows that under this assumption, FLT is very likely true. So if FLT is false, it probably wouldn't be due to some coincidental counterexa
