I was on a night out years ago for a friend's birthday, who, for whatever reason had chosen to have it at the Casino under the Empire cinema on Leicester square. The cashpoint there only gave out £50 notes. This is when I realised I couldn't afford this birthday party.
A very small number of cashpoints in London dispense them.
Also, there was a theatrically released biopic for Hawking and he was featured on an episode of the Simpsons, I think he's pretty mainstream.
Edit: Anyone care to comment on why you killed this?
It's only the equation which displays the definition of Bekenstein-Hawking entropy which is connected to Hawking.
I'm not an expert in designing coins, but I feel this is not the best way to visualize Hawkings impact on science.
I still quite like the design though and I suspect it would look a lot more tasteful when seen on the coin itself rather than viewed online (which might have had the images contrast turned up to make the dips and peaks of the pressing more visible)
I didn't see the equation before, nor see a thumbnail: which makes it appear to have an actual hole.
He's ... not really 'appearing' though, is he? His name is. Why no illustration of the great man himself?
Darwin is the only exception I can think of, probably because by depicting him and a chimp, you are actually depicting the work.
"Prof Hawking has also been suggested as the new face of the £50 banknote, which will feature a scientist. A decision will be made in the summer."
In the US, the mint releases a lot of commemorative coins that ostensibly and legally have a face value, but in fact will never be used as money. Contrasting with that are the state and national park quarters, which mostly circulate normally.
Some people collect them by getting bulk change from their banks and searching through. Here's a youtube video: https://www.youtube.com/watch?v=GrLpq9u90Ls
You get to see from this video that there are a load of these coins in the UK.
Thanks for the comment. I haven't been to the UK for 20 years (sadly).. I do remember from back then the differing pound coins.
People seem to avoid spending them for a little while, show someone if it's one they've not seen before, and perhaps put them aside at home, but eventually spend them again.
This is a nice way to commemorate him!
Edit: https://www.royalmint.com but it's going to cost me... a lot.
How long before Tim Berners-Lee gets on a British banknote or coin?
Will this happen before or after Charles Babbage, Ada Lovelace, or Turing?
And will Donald Davies ever get his recognition?
And will physical money even still exist by this point?
