From Wikipedia :
> Throughout his career, Erdős would offer payments for solutions to unresolved problems. These ranged from $25 for problems that he felt were just out of the reach of the current mathematical thinking (both his and others), to several thousand dollars for problems that were both difficult to attack and mathematically significant. There are thought to be at least a thousand remaining unsolved problems, though there is no official or comprehensive list. The offers remain active despite Erdős's death; Ronald Graham is the (informal) administrator of solutions. A solver can get either an original check signed by Erdős before his death (for memento only, cannot be cashed) or a cashable check from Graham.
I wonder if anyone else will continue the tradition.
Very sad news in any case.
That's all. Just a small memory from a random person.
I wasn't a math major and had no idea who he was, but I remember some students mentioning that he was a well-regarded mathematician. He was a good teacher as well.
Fan, who was also Ron's wife, has a webpage about him: http://www.math.ucsd.edu/~fan/ron/
Here is the one on his famous, eponymous number:
"The applications aren't the point," Graham says. "I look at
mathematics pretty globally. It represents the ultimate structure and order. And I associate doing with [sic] mathematics with control. Jugglers like to be able to control a situation. There's a well-known saying in juggling: 'The trouble is that the balls go where you throw them. 'It's just you. It's not the phases of the moon, or someone else's fault. It's like chess. It's all out in the open. Mathematics is really there for you to discover."
-- Ronald Graham
Ditto for computer programs: they always do exactly what you tell them to do, which is rarely what you really want.
I guess this is a joke since I think you are good at programming, but on a more serious note if anyone actually has this problem they might want to change to a different language.
With a few different languages I actually feel they do what I want 99% of the time or more.
I'll leave out naming any names here as I'm not trying to change anyone who is currently happy where they are.
Donald Knuth famously wrote: "Beware of bugs in the above code; I have only proved it correct, not tried it.", see also: the doctrine of testing.
Ironically, the first ever computer bug does not fit your claim .
At that point you have reached the zen of juggling.
Truly a loss.
what he did to facilitate Erdos' way of life has always made me envious of his altruism. I wish I could be that good of a fellow human.
The Reddit discussion at https://www.reddit.com/r/math/comments/hmngx7/ron_graham_pas... has comments by puleshan aka Steve Butler giving the time and place of death as 7:30 PM Monday night in La Jolla. But nowhere can I find a cause of death.
(The obvious guess given his age and the times being COVID-19...just like Conway.)
I wrote about how I first met him, and while we didn't meet often, it was always a pleasure, and he always greeted me warmly. I'm sad to think I won't see him again. I'll miss him.
Maths is wacky.

 And here is the man himself describing it
I'd write it out, but this margin is too narrow.
Very entertaining read.
What a life.
