Van Gogh’s Starry Night.
But I found this and I thought, "Oh, what a vaguely interesting thing." And then I got to the part about the Hubble Space Telescope, and, let me tell you: Mind. Blown.
We've got the set up here, but you have to watch the video for the full effect. It's all the way at the bottom.
Get this: Van Gogh was a pretty cool artist (duh), but as it turns out...
What’s the truth behind when you take off an ear?
...he was also A SCIENTIST!*
*Pretty much.
Here's the story.
While Van Gogh was in an asylum in France, after he mutilated his ear during a psychotic episode*...
(*Or, and I'd like to thank the entire Internet for pointing this out, there's a theory that his friend Paul Gauguin actually cut off his ear, in a drunken sword fight, in the dark. The more you know!)

...he was able to capture one of science's most elusive concepts:
~~~TURBULENCE~~~
Turbulence expressed through art.
Although it's hard to understand with math (like, REALLY HARD), it turns out that art makes it easy to depict how it LOOKS.
So what is turbulence?
Turbulence, or turbulent flow, is a concept of fluid dynamics where fluid movements are "self-similar" when there's an energy cascade — so basically, big eddies make smaller eddies, and those make even smaller ones ... and so on and so forth.
It looks like this:
Pictures explain science.
See? It's easier to look at pictures to understand it.
Thing is, scientists are pretty much *just* starting to figure this stuff out.

Then you've got Van Gogh, 100 years earlier, in his asylum, with a mutilated ear, who totally nailed it!
Science studying Van Gogh.
The folks who noticed Van Gogh's ability to capture turbulence checked to see whether other artists did the same. Most impressionists achieved " luminance" with their art (which is the sort-of *pulsing* you see when you look at their paintings that really shows what light looks like).
But did other artists depict turbulence the way Van Gogh did?
NOPE.
Capturing concepts of nature.
Even in his darkest time, Van Gogh was able to capture — eerily accurately — one of nature's most complex and confusing concepts ... 100 years before scientists had the technology to observe actual star turbulence and realize its similarity to fluid turbulence mathematics as well as Van Gogh's swirling sky. Cool, huh?

Is it always best to be honest with friends?
The move towards unique names has caused controversy in families, especially among the parents-to-be and their in-laws. But, as you’ll see in this story, it can cause problems among friends, too.
A Reddit user who was once known as Shayleigh recently shared her conflict with a friend on the AITA forum to see whether she was in the right.
Friends fight over baby names.
“One of my friends found out she was pregnant a few months ago, and she's really excited to be a mother. I'm happy for her and think she'd make a good mom, but there's one problem; she wants her baby's name to be unique and special, but the way she's going about it is terrible,” she wrote.
“What I mean is, the name she plans on using is godawful. If it's a boy, she's going to name him ‘Daynger’ (yes, spelled like that to be unique), and if it's a girl, she's going to name her ‘Tinkerbelle,’” she continued.
This woman not only wanted to be unique by naming her child after a Disney character, but she combined the names of two characters, Tinkerbell from “Peter Pan” and Belle from “Beauty and the Beast.”
The woman formerly known as Shayleigh leveled with her friend, saying her child would get bullied if they were named Daynger or Tinkerbelle. The former Shayleigh wasn’t just a wet blanket, she knew what it was like first-hand to have a unique name. After all, she was bullied for being named Shayleigh by being called “Gayleigh.” She was also the victim of her parents using the “leigh” for “ly” naming convention, which many see as cringeworthy. Her name caused her so much stress that at 19, she had it changed.
According to Stop Bullying, being targeted by bullies can cause anxiety and depression and the effects can lead into adulthood.
The honest remark led to a falling out among the friends.
“She got really upset and told me I was being unsupportive and I was a shi**y friend,” the woman formerly known as Shayleigh wrote. “She's been ignoring my texts ever since, and it's been more than a week. I'm starting to feel kind of guilty over what I said.”
The commenters on the post overwhelmingly supported the poster for being honest with her friend.
"A baby’s name should work for them from birth to school to career to retirement. She’s only thinking of how cute a baby Daynger/Tinkerbelle would be and not thinking of how much her tween will hate her for that name," Regular-Switch454 wrote. "She needs a reality check. She’s naming adults here. Those names won’t set her kids up for their best shot at life and she needs to accept that," Thoughtinspace added.
The good news was that the friends eventually reconciled and had a long talk about the woman’s baby name ideas.
‘“I carefully brought up some of your points, and suggested using the name "Belle’ for a girl, with ‘Tinkerbelle’ as a nickname; she thinks it's cute and liked the idea,” the woman formerly known as Shayleigh wrote. “She did decide to use ‘Daynger’ (still spelled like that) as a middle name, which isn't nearly as bad as using it for a first name. On the bright side, the kid can tell people, ‘Danger is my middle name.’”
