Stephen Hawking will live forever on this memorable black caveman Stephen Hawking will live forever on this memory

Any place, physics or all-around science geek may agree that Stephen Hawking is immortal, but now his work is remembered on a coin that must last until all the black holes in the universe evaporate.

UK Royal Mint has released the most appropriate coin ever to keep the late physicist's memory alive forever, or at least as long as the earth is around. It's a bit like a graphic you can fit in your pocket. His name and the equation for the entropy of a black hole (more on that in a second) appear just above the event horizon of a conceptual drawing of a black hole.

"I wanted to fit a big black hole on the little coin and desire [Hawking] was still chortling at the thought, "designer Edwina Ellis told the BBC about 50p (about 72 cents) coin. She would have to legitimize how he" made difficult issues available, engaging and relatable ".

If the black holes are evaporated – this is where entropy comes in. Entropy describes how a system loses energy at a certain temperature. Because nothing, not even light, can escape the extreme gravity of the heavy hole, Hawking began to wonder what made for entropy. This is how the concept of Hawking radiation emerged. Black holes he thought gradually lost, thereby radiating matter from their surfaces.

The equation of the coin merges general relativity (gravity) and quantum mechanics (law of the smallest particles) to explain how even black holes will spread in the ether over billions and billions of years.

"It's a good privilege to be on a coin," said Hawking's daughter Lucy, "and I hope my father would be happy to be with Sir Isaac Newton and Charles Darwin as scientists who have done it for money. "

If you do not live in the UK, it does not mean that they are light years away. Get one right now from the Royal Mint website and put a black hole in your pocket.
