Hmm, we didn't go over velocity sums in class, and i don't see any formula for it :S

Homework Statement OK, we have started all this special relativity stuff, and I must admit I am confused, all this Inertial Reference Frame stuff :S Here's the problem: Two particles are fired at the same time from a point, with equal speed u, in orthogonal directions. Show that the...

ah of course, using the susceptibility = permittivity - 1 thats what i was looking for, thanks, i just couldn't see it :P

i go to queens (number 7) on that list, its very good, although many ppl are turned off by the idea of staying in northern ireland. its really not half as bad here as its sometimes made out to be! queens have just finished a major upgrade of their physics department, with loads of new equipment...

Hi, I'm stuck on a certain question in a tutorial sheet, and would appreciate a nudge in the right direction. The problem is in one particular question to which I missed notes due to illness, and won't have time to copy up before they need handed in. The question is on dipole moments: The...

the new james bond is supposed to be more like in the book, a "darker soul", rather than some guy who lounged around in a bed with some women and drank martinis :) the pictures that they show in the articles of daniel don't really show him in his best, if you look at him in Layer Cake, he...

they sound way freaky, man! when you say "trip" you mean "acid trip" right? right?

hmmm... its taking its time...

ok i read the article, and i can see the point you are making, HOWEVER... doesnt the article make the point that it is a SOCIAL type of sexual behaviour, not something that is an ingrained genetic preference? this is not the same thing, as your own source says: "For these animals, sexual...

just to make it clear, i am not trying to insult you or any other gay person, nor am i trying now to hijack the tread, so i will keep this brief. why do you seem to just want to hate me or something, because i questioned your beliefs? i haven't insulted you in the slightest in the entire...

well, being straight myself, i wouldn't know about you or your friends. but i was pointing out is how the gay community is seemingly trying to make it "fashionable" to be gay, (gay pride, etc) when, well if everyone was gay we'd all end up extinct :eek: my other point was (not well explained)...
