Of course they're not, but OP kind of implied that it wasn't necessary to read a lot of pages of mathematics when he said > you can't sit thru lots of pages of mathematics text Even if you watch those videos, you still nee

These are great resources, but the ultimate approach is wrong. In order to truly learn math, you must be willing to invest the time and "sit through lots of pages of mathematics text" and also do a ton of problems, many of which

This is very dangerous and an awful way to compute the least squares fit due to potential numerical issues with calculating the inverse of the matrix. I wish he would put a warning in a huge bold header to never do this for actual producti

Why is this still the top voted comment? It's clearly been rebuked as false.

I'm sure those proofs at the time were novel to the student but obviously not the professor who assigned the problem. That's how the student learns.

That doesn't follow from the fact that black holes are "black". For example, black holes can emit a ton of radiation from accretion disk as matter accelerates and falls inwards, radiating huge amounts of energy [0]. Two naked

Dropbox seems to have an IPO on the horizon. They'll probably be the first. They and AirBnB have always been touted as the darlings of YC, so no surprise there.

I take 15 min power naps during the day at work and encourage my employees to also. It's refreshing exactly in that way you said. I wish more companies encouraged napping. Better than a cup of coffee any day.

You could say the same thing for intelligence, which is arguably more valuable. Intelligence allows you to have a comfy 9-5 job and long-term stable career making 6 figures a year writing software and doing something you love.

That's a pretty silly strawman to build up and then tear down. That's tantamount to saying an engineering degree is just a piece of paper. Of course it implies a lot more.

Or, I don't know, they learned useful and relevant things while earning those degrees?

That's a pretty silly, cynical, and useless way to look at it. The evaluation should be from a technical point of view of code quality: did the code do what it was supposed to do, and do it well? After all, that's what's bein

I don't think it will matter at all. Literally, zero impact. Chess computers crush the world's best humans, yet here we are in meatspace, still vying to win the human world chess championship. Also, 99.99999% of players realize th

The difference seems to be in the culture of the community, which they've done a good job of cultivating from day 1. Quality is valued, and so are expert opinions. I doubt they pay anybody.

Really? The math content on Quora is generally top notch. It depends on who answers the question of course, but there are many high quality writers on Quora with deep understandings of mathematics.

Ed Witten was very good at math when he was young. He scored exceptionally well in the American Mathematics Competition. He didn't pick physics up out of nowhere, he already had a quantitively talented mind.
