Re: Fermi's questions!!!

Hi;

Shrinking myself and my ruler using Benes' miniaturization formulas ( see Fantastic Voyage ) I was able to measure very roughy the size of a proton. I got 10^(-12) mm in diameter. More difficult was measuring the diameter of a hydrogen atom. That darn electron kept hopping and shrinking and reappearing all over the place. Was actually kind of electron cloudy, I thought it was going to rain. Anyway, the diameter of the hydrogen atom is 5 x 10^(-8) mm.

Forming a simple proportion:

Solving for d =3.7 kilometers in diameter which means it is about as wide as Manhattan.

In mathematics, you don't understand things. You just get used to them.

I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.

Yes, I saw that. Will work on it.

Yes, strange about those titles. You can call feminine royalty, "your highness" but you can not say to masculine royalty, "your high."

Re: Fermi's questions!!!

well,i think you say highness to both males and females because i think the -ness in this context isn't for femaleness.

I will definitely try that next time I am in the presence of royalty. If I get in trouble I will blame you.

Re: Fermi's questions!!!

Hmmmm. Yes, but if I am wrong I will be either beheaded or imprisoned in a dungeon for 175 years. I will bet if Rico was facing the same threat he would not be so quick or so sure of his answer.

Re: Fermi's questions!!!

A wise man once told me that with one six shooter he could hold back 2000 men.

That problem requires much estimation, it will take me a while.
