The UK Royal Mint Is Putting A Black Hole On A Coin To Honor Stephen Hawking

The United Kingdom's Royal Mint wants to honor the work of Stephen Hawking with a commemorative coin featuring the physicist's name above concentric circles representing a black hole. It looks pretty awesome.

The famous scientist died last year and is believed to be black holes can evaporate via "Hawking radiation." Non-scientists know him through his A Brief History of Time, his various appearances in pop culture, and his ability to thrive against the paralyzing effects of his motor neurone disease.

Edwina Ellis designed the coin, reports the BBC. Not only is it really amazing that it's a conceptual drawing of a black hole on a coin, but I'll bet it's the most advanced physics equation ever to appear on currency.

That aspect of the invention can be described as a system of energy dispersal at a given temperature. It's interesting to ask the entropy of a black hole, because we know that it can not even take a black hole; but at the same time, the laws of physics say that the entropy of a system can not spontaneously decrease.

Hawking's work on the idea of ​​Hawking radiation, the theory that black holes must radiate matter from their surfaces, so known as their event horizons. The idea represents an important milestone in physics, and the equation is an important combination of the laws of gravity, called general relativity, with the laws of the smallest particles, called quantum mechanics.

Uncirculated copies of the coin are available for purchase at the Royal Mint's website.
