Re: Fermi's questions!!!Good. I will post more if I think of any. 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 #127 20120827 05:10:25
Re: Fermi's questions!!!It would depend on what you mean by running around the earth. A great circle? 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. #128 20120827 05:12:40
Re: Fermi's questions!!!Let's say the equator.

Re: Fermi's questions!!!4x4x2? Meters, inches, feet? 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. #130 20120827 05:55:52

Re: Fermi's questions!!!A typical burger (quarter pounder ) of this type has a 4'' diameter bun. This can verified on the net and was standard from 2009. We round this to .1 m That is of running at 12 mph. So we can run around the earth approximately 147 times. In mathematics, you don't understand things. You just get used to them.

Re: Fermi's questions!!!What does General Sherman (a sequoia tree and the world's largest tree) weigh, measured in units of US dollar coins? #133 20130420 18:13:54
Re: Fermi's questions!!!Avagadro number (6 times 10^23 maybe)
