That is pretty self evident why Tesla is such a big internet celebrity. People are curious/fear about what is unknown...since Tesla's experiments seem to be "flashy" and add his reclusive image of "mad scientist"... and the fact that he made a bunch of random statements about having...

Philosophy is not a set of beliefs...it is a methodology. 1) In Analytic philosophy dept...which is the most unis in USA/England - philosophers who do philosophy of science...almost all studied physics or math. In my undergrad. education in philosophy out of ~10 profs. 5 had degrees in...

1) The most reasonable position seems to be to accept that you are a limited human being...as we all are...and thus we cannot find out some things...ever...such as empirically prove/disprove God...etc. 2) So far...Scientific Method IS THE BEST method of getting consistent results from empirical...

It is totally not relevant what people call "elementary" or not...this is merely a convention and doesn't prove anything. Electron is said to be a point particle just because all the measurements thus far have not established any particular size. As an approximation this is good. If it...

Things with no spatial extension still make no real physical sense (let's leave aside Wikipedia if you want). Example1: you cannot properly integrate or sum over anything spatially if it has 0 extensions... Example2: suppose you have a ball of finite size, now you take the ball to be a point...

I don't get how that makes any sense that electron has 0 volume As an approximation it can be thought of as having 0 volume, but as a physical fact that is just ridiculous. If something has no spatial extensions, then how can it exist if there is nothing in that space (otherwise it would...

I think you don't realize connection between all the sciences (be it natural or social, etc.). In the deepest level, they are all very similar - but differ in their criteria for what is "proof" and establishment of results. I have spoken on such topics and other philosophical issues concerning...

Hello. Some background on me: Just graduated with physics major and am going to graduate school this fall. However, due to additional focus on philosophy I couldn't focus on properly learning either math or physics. I am relatively capable, however, I have small knowledge with many gaps to...

To cosmogirl: In USA it is 6 years (on average), because the first 1-2 years are classes. If a student comes directly from bachelor degree he is most likely not prepared enough in advance topics. However, some students come with a very strong MS degree or already did research elsewhere, they...

Probability, that random variable X(n) will take a value m.

Good Day. I need to solve reccurent sequence. P{X(n)=m}=SUM(from 1, to n-1)(p(n,k)*P{X(k)=m-1} P{X(0}=0}=1 P{X(1)=0}=1 p(n,k)-some const witch depends on n and k. I need full solvation of this problem. Thanks for help.

Your avatar >>> all statistically possible pics of your work places ... :)

Haha, you reminded me of a joke about physics... So world ended and all physicists went to heaven (obviously, it could be otherway?..didnt think so :) ) so they didnt know what to do...so decided to play hide and seek. So Einstein started counting and Newton instead of running to hide was...

We need a lot more pics of theoretical desks :)
