I bet you didnt know that

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"

Maths.

("Math" sounds horrendous. In fact, America in general can be awfully uncultured. Was it on here that I learned that they dub David Attenborough in the US?)

Talking of bubbles;

During the dot com bubble, AppNet Systems filed for an IPO under the ticker symbol APPN. The ticker was then currently being used by Appian Technology, a microcap stock with trading share volumes averaging 200 per day, with the ticker symbol being assigned to AppNet following it's listing.

Two days after the IPO filing by AppNet and when stock couldn't actually be traded, 7.3 million shares of Appian were traded in one day driving the price up by 142,757 percent in a bizarre case of mistaken identity.

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.

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

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.

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.

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.
