Professor Stephen Hawking, who died in March 2018, was one of the world's most renowned physicists, known for his work on black holes. And now, the world famous physicist has been commemorated on a new 50p coin, which is now available to buy from the Royal Mint website.
Professor Hawking joins a number of other well-known scientists who have appeared on coins, including Sir Isaac Newton and Charles Darwin. The new 50p design is inspired by the Professor's work on black holes and includes a depiction of a black hole with a scientific equation and his name.
On the Royal Mint website, the coin's designer Edwina Ellis, said, "Stephen Hawking made difficult subjects accessible, engaging and relatable and this is what I wanted to portray in my design, which is inspired by a lecture he gave in Chile in 2008."
Continuing, "Hawking, at his playful best, invites the audience to contemplate peering into a black hole before diving in.
"I wanted to fit a big black hole on the tiny coin and wish he was still here chortling at the thought. I am sure he would have thought of ways to harness the shiny table of the coin too. You feel he cared about all of us understanding."
