Where "complex numbers" is Chinese, "imaginary numbers" is German, and "2D numbers" is English in this analogy.

This has also a great intuitive explanation of why sqrt(-1) is a rotation.

So they help people part with their money. Then, if I was an advertiser, I'd put my money elsewhere:

> For example, while Google users click on the first advertisement for search results an average of 8% of the time (80,000 clicks for every one million searches), Facebook's users click on advertisements an average of 0.04% of the time (400 clicks for every one million pages).

What value does Facebook provide as a company? Do ads create value?

And good sleep, low stress, and proper hydration. Working out is ideal but hard to keep up which is why a lot of people quit the gym shortly after the new year resolution rush.

> The Human Genome Project (HGP) was one of the great feats of exploration in history - an inward voyage of discovery rather than an outward exploration of the planet or the cosmos; an international research effort to sequence and map all of the genes - together known as the genome - of members of our species, Homo sapiens. Completed in April 2003, the HGP gave us the ability, for the first time, to read nature's complete genetic blueprint for building a human being.

New comment by vinchuco in "Coffee drinking inversely associated with mortality"

Leading causes of death in the US :

https://www.medicalnewstoday.com/articles/282929.php

#1 is heart disease

Causes: excessive alcohol consumption, smoking, no regular exercise, stress

I could be wrong but no exercise seems to be the main culprit based on what the disease actually is. Given that coffee increases your heart rate may suggest a causal link.

Edit: Link to the actual study from the article https://jamanetwork.com/journals/jamainternalmedicine/articl... the comments are worth a look.

> A given problem, such as the integral we just computed, may appear to be intractable on its own. However, by stepping back and considering the problem not in isolation but as an individual member of an entire class of related problems, we can discern facts that were previously hidden from us.

A professor put it this way: "the more you assume, the more you can prove"

No, you see, the article author is playing a supergame which is won by finding a play-to-lose version of a game. The parent commenter is simply playing the play-to-lose version of that supergame.

Here is a tic-tac-toe version https://en.wikipedia.org/wiki/Tic-tac-toe_variants

And a chess version https://en.wikipedia.org/wiki/Losing_Chess

A large (finite?) list of chess variants also exists https://en.wikipedia.org/wiki/List_of_chess_variants

To be expected but nonetheless amazing how changing one bit in the game rules can have strong effects in gameplay and strategy.
