Any space, physical or maladjusted of science can be of agreement on the fact that Stephen Hawking is immortal, but now his work is remembered on a coin that should last until all the black holes in the universe will not evaporate .

The British Royal Mint has released the most appropriate currency ever to keep the memory of the deceased alive, or at least until the Earth is around. It's a bit like an epitaph you can put in your pocket. His name and the equation for the entropy of a black hole (more on this in a second) appear right above the event horizon of a conceptual drawing of a black hole.

"I wanted to insert a big black hole on the small coin and wish [Hawking] he was still giggling at the thought, "the designer Edwina Ellis told the BBC about the 50 p coin (about 72 cents). She wanted it to embody the way it" made difficult subjects accessible, engaging and relatable ".

Speaking of those black holes that evaporate – this is where entropy comes into play. Entropy describes how a system loses energy at a certain temperature. Since nothing, not even light, can escape the extreme gravitational force of a black hole, Hawking began to wonder what he did entropy. This is how the Hawking radiation concept emerged. Black holes, he believed, must gradually lose and then radiate matter from their surfaces.

The equation on money fuses general relativity (laws of gravity) and quantum mechanics (laws of smaller particles) to explain how even black holes will dissipate in the air for billions and billions of years.

"It is a great privilege to be present on a coin," said Hawking's daughter, Lucy, "and I hope my father would be happy to be at the side of Sir Isaac Newton and Charles Darwin as scientists who made money."

If you don't live in the UK, that doesn't mean they are light years away. Get one right away from the Royal Mint website and put a black hole in your pocket.
