WHAT’S BEING CLAIMED:
- Black hole will be the main feature of a new commemorative coin released by the Royal Mint of the United Kingdom in honor of the late scientist Stephen Hawking.
- Aside from a 2D image on the new 50-pence coin, Hawking’s name, as well as one of his signature theorems, are also presented on lines that constitute a black hole.
- Hawking, along with fellow physicist Jacob Bekenstein discovered the Bekenstein–Hawking equation which reconciles the relationship between the entropy of black holes to its event horizon.
A commemorative coin featuring a black hole to honor the late physicist Stephen Hawking and his favorite subject has been released by the Royal Mint of the United Kingdom.
On a new 50-pence (66 cents) coin, Hawking’s name is featured on a field of concentric and circular lines that represents a black hole. Actually, this is a 2D image where the surface of the coin seems to indent forward at the center of the black hole.
Another trademark of the coin is the equation S=(k*A*c^3)/(4*hbar*G) otherwise known as the Bekenstein–Hawking equation and one of Hawking’s signature theorems.
Named after Hawking and fellow physicist Jacob Bekenstein who developed the equation, it states that the entropy of a black hole which includes its inner randomness and disorder, is proportional to the area of its event horizon. This means as an object falls into a black hole, the black hole’s entropy increases.
This equation also helped Hawking to discover a phenomenon now known as Hawking radiation which is among his celebrated discoveries. According to the phenomenon, even as black holes vacuum up huge amounts of matter, they gradually discharge tiny particles into space.
Definitely, the new Hawking coin will look cool on your shelf. The Royal Mint’s website states that you can order from their website for 10 pounds plus shipping (about $13) and that coins will be shipped by late April.
If you think that’s too pricey for a 50-pence coin, take note that this is for commemorative use only and the Mint assures you that this will never “appear in your change.”
In the meantime, Hawking is being considered as a candidate among famous English scientists whose face will be featured on the Bank of England’s new 50-pound bill. Later this year, the name of the scientist will be announced.
Hawking died on March 14, 2018. He was 76 years old.
