Euler.

The limit operator is just an excuse for doing something you know you can't.

I was speaking of modern, living mathematicians.

In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

### Re: The Two Trains and How Fast

But I am living, sort of. Euler is gone.

Also, I am not a mathematician!

Oh, yeah. You're a numerical analyst. And the best one was a chemist. Makes sense. But, if you're not a mathematician then the rules don't apply to you. You can have two constants with your name on it. What is the one you had in mind?

### Re: The Two Trains and How Fast

I remember that problem. Isn't it one of the ones you came up with?

This is the easiest one:

Evaluate the above integral to as many digits as you can. Find a good way to do so.

Is that analyst Robert Israel?

Nope, Robert is good but not that good. It is the legendary Forman S. Acton.

Oh, he's the author of that book you mentioned "Numerical Methods That Work".

### Re: The Two Trains and How Fast

That is correct. If you have a problem to solve, if it is a numerical problem, then you bring it to him. You do not bother with a mathematician!
