Re: The Two Trains and How FastEuler. The limit operator is just an excuse for doing something you know you can't. “It's the subject that nobody knows anything about that we can all talk about!” ― Richard Feynman “Taking a new step, uttering a new word, is what people fear most.” ― Fyodor Dostoyevsky, Crime and Punishment #27 20120727 04:22:35
Re: The Two Trains and How FastI 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. #28 20120727 04:30:55
Re: The Two Trains and How FastBut you're a thousand years old! The limit operator is just an excuse for doing something you know you can't. “It's the subject that nobody knows anything about that we can all talk about!” ― Richard Feynman “Taking a new step, uttering a new word, is what people fear most.” ― Fyodor Dostoyevsky, Crime and Punishment #29 20120727 04:31:31
Re: The Two Trains and How FastBut I am living, sort of. Euler is gone. 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.

Re: The Two Trains and How FastYou're not dead? The limit operator is just an excuse for doing something you know you can't. “It's the subject that nobody knows anything about that we can all talk about!” ― Richard Feynman “Taking a new step, uttering a new word, is what people fear most.” ― Fyodor Dostoyevsky, Crime and Punishment #31 20120727 04:40:08
Re: The Two Trains and How FastAbout time you learned his name. 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. #32 20120727 04:45:08
Re: The Two Trains and How FastI remember that problem. Isn't it one of the ones you came up with?
Is that analyst Robert Israel?

Re: The Two Trains and How FastNope, Robert is good but not that good. It is the legendary Forman S. Acton. 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. #34 20120727 04:56:40
Re: The Two Trains and How FastOh, he's the author of that book you mentioned "Numerical Methods That Work".

Re: The Two Trains and How FastThat 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! 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.
