I bet you didnt know that

Cartouche

As people here work in various jobs / professions they might know things from work or study no one here knows yet. this is what this topic is about.

what do you know that we have never heard of?

Eg: you don't need to be great at maths to be an architect

this is obvious to me but everyone says to me "i wanted to be an architect but i was bad at math,i can barely add"

. In 1923, jockey Frank Hayes won a race at Belmont Park in New York despite being dead — he suffered a heart attack mid-race, but his body stayed in the saddle until his horse crossed the line for a 20–1 outsider victory.

^ The article above states that.... "This ruling makes Frank Hayes the only jockey to win a race while deceased. In fact, it is the only time in sports history when a competition was won by a dead man."

Which isn't strictly correct. Jochen Rindt won the 1970 Formula 1 championship posthumously. He was killed in practice at Monza for the Italian Grand Prix. Jacky Ickx could have won it, but he failed to win the last 3 races, so the lead that Rindt had at the time of his death was sufficient to claim the championship.

Its an interesting fact, but it doesn't make the prior one incorrect. Winning a championship as a result of compiling points from races while alive, isn't the same as winning a race while dead.

It is a competition though, so the original sentence is just badly phrased

Olympic gold medals are made mostly of silver. The last Olympic Games to use actual gold medals was the 1912 event held in Stockholm. Currently, gold medals are made up of 93 percent silver and six percent copper, and the remaining one percent is for the highly prized gold finish.

Nobel Prizes are gold.

Back in 1940 it was illegal to export gold from Germany. And if you were Jewish it was pretty much death penalty illegal.

So if you were in newly captured Denmark and were in possession of a pair of Nobel Prize medals with the names of the Germans who won them and were certain the invaders would pay your lab a visit shortly there'd be a problem for all concerned.

You can't bury the medals as that would be noticed and you are damn sure the Germans will take the place apart so what to do ?

You're in a lab ... so the solution is the solution.

You dissolve the gold in acid and leave it sitting in a flask for the duration.

Dogger Bank (without looking it up, where's the fun in that)? I remember a lot of cruisers being sunk there in succession. Didn't know about him though.

Every second the Sun fuses 700 million tonnes of hydrogen into 695 million tonnes of helium. The remaining 5 million tonnes are turned into the energy needed to prevent it collapsing under its own weight.

Just to combine my last post on Quantum Mechanics with this. The hydrogen nuclei don't actually have enough energy to fuse together. When they approach each other their electrical repulsion increases so quickly that they can't pick up enough speed to overcome it.

However if they were very close, the strong nuclear force would pull them together more than the electric repulsion could push them apart. Under classical mechanics this would be impossible as they simply can't push through the electrical barrier enough to get this close.

However, as mentioned above, since the nuclei are quantum particles they are constantly randomly jumping between locations. Very rarely they will randomly appear next to each other, close enough for the strong nuclear force to overcome electric repulsion and fuse them. This fusing then providing a flux of high energy photons that act against stellar collapse.

Although rare, it occurs enough times in a stellar core to support the star against its own weight. So even stars are held up by quantum randomness.

5 million tonnes are turned into the energy

This isn't quite what happens, I'm still thinking how best to explain the "real" sequence of events.

I'm aware. I did simplify it. The complicated version involves all sorts of hijinks that would make your head explode. I'm only a keen amateur in the end so I'm not going to pretend I fully understand it.

Not more complicated I would say just more abstract (there's really only three steps to the process), really due to the fact that nothing can be turned into energy. Energy is a property of objects, not a thing itself. Just as one cannot be turned into momentum or position.

As a first approximation you could say that the hydrogen is turned into helium and a bunch of high energy photons. The pressure exerted by those photons holds up the star.

EDIT: Let this not detract from Ineedaname's contribution, technical quibbling is all this is.

Anish Kapoor is the only artist who is allowed to use Vantablack (the blackest black).

In response to this exclusivity, another artist Stuart Semple collaborated with scientists to create what he thinks is the Pinkest Pink.
He sells it on EBay to everyone except Anish Kapoor

There's something about this that's so black, it's like how much more black could this be? And the answer is none. None more black.

Strangely, that article doesn't mention the fact that Schrodinger took out Irish citizenship and lived in Ireland for 15 years. He came here in 1939 as he found Ireland to be tolerant of his views and DeValera offered him a job.
