Let me tell you how smart Einstein was.
In one of his equations he put in a term that he later regretted putting it and he called it his greatest blunder he looked at his equations and his
equation showed that the universe had to be either expanding or collapsing.
No one had any idea that the universe, which is everything, would be doing anything.
So he says: "This can't be right - let me put in this term". It's a legitimate mathematical term, but physically - what the hell are you doing Albert?!
And he says this term will help stabilize it from collapse - and it's a pressure Force to push outward and that'll stabilize it.
Later on Hubble discovered that in fact the universe was expanding and he didn't need the term, because he could have predicted, that the universe
should be expanding or contracting. But he didn't. He put in this term.
He said this is his biggest blunder.
Now you know what Einstein's actual biggest blunder is? Saying that was his biggest blunder.
Because in fact in 1998 we discovered a pressure in the universe pressing against gravity, that is exactly the term that he put in.
That's badass Smart.

and now something completely different:
když vyloučíte náboženské svátky, tak nejčastěji a nejmasivněji slavený svátek v celém světě je... den nezávislosti na Británii.
Z 225 zemí světa:
163 slaví den nezávislosti
z toho 65* slaví nezávislosti na Velké Británii
z toho 48 to má jako státní svátek.
* 65 podle wiki, 62 podle Guinnesovy knihy rekordů, původ rozdílu se mi nechce zkoumat

: automatika:
The U.S. Army trained dogs for a number of tasks during World War II. From checking for mines to guarding prisoners of war, the dogs performed admirably, but a few special dogs actually earned jump wings. To solve the problem of providing assistance to downed airmen in isolated locations, the Army, with the help of its Canadian brothers, trained dogs to jump from planes and bring the fliers supplies, aiding them in their treks to safety. Based on the idea of the St. Bernard with a barrel of whiskey under its chin heading out into the snow to save stranded hikers, lighter Siberian Huskies replaced the St. Bernard, and K-rations and water replaced the barrel of whiskey.
To prepare the dogs for their jump, soldiers would take the animals, with full packs, on 75-mile hikes to relax before their ordeal. Next, the dogs were suited with parachutes—sometimes with two dogs to a chute—and loaded aboard a transport plane. The plane flew to a desired height and target zone where the dogs were pushed out of the side door.
The parachute, on a static line, automatically opened as the canines cleared the doorway.
Once on the ground, they could deliver supplies and aid the stranded airman.
