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:

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.

Re:Coffee drinking inversely associated with mortality on Monday July 23, 2018 @10:19AM (#17592927)
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.

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.

Cats are smart enough to communicate with humans, I have no doubt of that. N=2, but once I had a cat that woke me up at night to point out a possum had entered the house and was hiding under a piece of furniture, and once I had one which (different house) gestured me to follow him in the chase after shooing away the intruder cat that kept stealing its food.
Here is also slime mold 'communicating' their knowledge to other slime mold https://news.ycombinator.com/item?id=17491547 .

For anyone that is fascinated by nature studies and would like to be exposed to more of them rather than the article about the article I can't recommend PNAS enough. Part of what motivated me to continue graduate studies.

"My hovercraft is full of eels"
"The single biggest problem in communication is the illusion that it has taken place" -GBS

It's a bit sad we can't yet fully communicate with other life here effectively. I wonder what ethical implications it would have if we ever got there. An analogy to the current state may be that of a man from another language trying to ask for directions to an autistic kid.

What does it mean to understand?

> Maybe I'm just paranoid

This common saying.

I'd rather be paranoid and informed than blissfully ignorant. But a person can only process so much while carrying on with their lives.

The jewel beetle attempts to mate with an amber glass bottle it finds attractive until it dies from exhaustion.

https://www.npr.org/sections/krulwich/2013/06/19/193493225/t...

We increasingly manufacture our own deception. Deep fakes, targeted advertising, you name it. We are both the beetle and bottle designers. It is definitely worth thinking about.

It's much easier to design glass bottles than to save beetles from the best and worst time of their lives.

Now, as crafty bottle designer, think of all the stuff you could do, given the necessary resources.
