United Kingdom issues new 'black hole' coin in honour of Stephen Hawking

The scientist died last year

In honour of the renowned British theoretical physicist Stephen Hawking, who passed away in 2018, the Royal Mint is issuing a special coin featuring a black hole design and the equation S=kAc^3/4hG, the so-called Bekenstein-Hawking equation.

Physicist Hawking presented astounding works on black holes, which were the inspiration of the designer while working on the coin.

Hawking, one of the world's best-known theoretical physicists who died aged 76 a year ago, joins the ranks of other eminent scientists such Isaac Newton and Charles Darwin to have a commemorative coin in honour of one of his greatest discoveries that black holes should not be all black.

She said she wanted to reflect the way he "made hard subjects accessible, engaging and relatable", in particular on black holes.

The national treasure died aged 76, on March 14, last year.

Hawking's discovery led scientists to the unavoidable conclusion that information is lost as a black hole forms and subsequently evaporates.

The Royal Mint shared a video of the coin on Twitter, saying that the coin is in commemoration of Hawking's "outstanding contribution to science".

Prof Hawking explained black holes in his best-selling book A Brief History Of Time.

Not only is it just the thing to remind you of one of the greatest minds in modern science, it's handy just in case you forget how to calculate the thermodynamic entropy of a Schwarzschild black hole of a given mass.

A limited number of gold and silver presentation coins, celebrating the life of Stephen Hawking, featured on the Royal Mint website and costing from £55 to £795, have all been reserved and are no longer available for purchase.

Lucy said: "It is a great privilege to be featured on a coin and I hope my father would be pleased to be alongside Sir Isaac Newton and Charles Darwin as scientists who have made it on to money".
