Physics question

whats physics
 
Well, here's something for him when he does turn up:
Imagine you are in a small boat with a large stone sitting in the bottom of it. The boat is floating in a swimming pool of water. What happens if you throw the stone overboard? Does the level of the water in the pool go up, down, or stay the same?

We can assume that the stone will be fully submerged in the pool once overboard.

this is a good one!

the level of the pool goes down.

Hi Samote! good to see you around bro.


LOL!

Apparently the network card built into my motherboard wouldn't work with the university's network connections, so I didn't have internet access for almost a week... and I've been busy moving back to school and stuff.

And if anyone can tell me the bloody purpose for requiring five credits in optics to graduate, please do. I thought the relevancy of that subdiscipline was limited to optometry and history majors desparately seeking a last-minute thesis topic in medieval European history.

Optics is necessary for the study of traveling wave tubes and klystrons, beam focusing in all types of electron emitters. Also in other magnetically focused particle beams.

What?! I thought the engineers did all that crap. Dammit. Lazy engineers.

Isn't their a singularity at n=1 where it reduces to a diverging harmonic series? And what am I summing to here?




:cow:

It's Euler's zeta function, clearly diverges at <=1, sorry, I was too quick on the draw with the post. The sum is defined from 1 to infinity. What I really wanted was a proof of his product identity,



where p = any prime number.

LOL, most of our engineers weren't EE's when I worked in the Electron Tube field but Math or Physics Majors. Our engineering department head and later Vice President was a Physics PhD/MBA. The guy that did most of our theoretical work was a Math PhD, created a lot of finite element analysis tools.
