Re: Fermi's questions!!!hi 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 20120128 13:49:28
Re: Fermi's questions!!!Okay, I got that, thanks. 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 20120129 02:07:26

Re: Fermi's questions!!!That formula was created using all the estimates. The 6.0225 x 10^23 is Avogadro's number and it is obviously not precise. The 22.4 and 21% are also estimates. 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: Fermi's questions!!!well suppose we put you in an indestructible cage first.now,since you're trapped you can peacefully calculate the number.

Re: Fermi's questions!!!Define an average size room? In your country it would be totally different than say England or Japan or the US. In mathematics, you don't understand things.

Re: Fermi's questions!!!well,let it be a room of size 4 by 4 by 2.

Re: Fermi's questions!!!Meters, I presume? 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. #36 20120129 03:29:04
Re: Fermi's questions!!!yup.i don't know how to use yards and such stuff.

Re: Fermi's questions!!!Okay, I will begin working on it. Cooking up a bag of popcorn of the movie theatre variety, I then proceeded to measure a few and take the average. My best estimate is that one popcorn has an equivalent volume to a 3 / 4 inch diameter sphere. So 825 000 popcorn would fit in the room. In mathematics, you don't understand things.

Re: Fermi's questions!!!then you shouldn't have posted the preedited post.anyway this forum doesn't have that rule!

Re: Fermi's questions!!!The first post ws to let you know I was working on it. How do you know this forum does not have that rule? 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. #42 20120129 09:12:13
Re: Fermi's questions!!!well why would i need that information if it will keep me from seeing your latest post.

Re: Fermi's questions!!!Yes, those are some of the rules. But as I said, I consider it poor form. Sort of like muttering to yourself in the street. 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. #44 20120129 09:28:47
Re: Fermi's questions!!!still those are the rules.

Re: Fermi's questions!!!I find it more distracting and difficult to follow when someone is double or triple posting at me, that is when I miss posts completely.

Re: Fermi's questions!!!well they are talking to each other.

Re: Fermi's questions!!!On the telephone? 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. #48 20120129 10:01:25
Re: Fermi's questions!!!no,in person.take that they are standing 2 (60 cm) feet from each other.

Re: Fermi's questions!!!Hi; Using the tables provided by wikipedia tha average male weight had to estimated at 78.6 kg . The average female weight as 66.2 kg. Now you just plug in to the formula: So the gravitational attraction between the two is 9.64 x 10^(7) newtons. In mathematics, you don't understand things. You just get used to them.
