I'm sure that's incorrect too... the object oscillating would lose energy due to damping on each oscillation (a damping due to gravitational energy exchange), until it eventually remained at the centre of the gravitational mass. edit: Just reading through all of them, and I'm getting irritated...

Just Graduated last week with a 1st Class Honours in Physics. I also got awarded a prize with my laboratory partner for best laboratory project for that year in the School of Physics... so I'm pretty happy. Now I've got to get a job, hopefully in something with some relation to Physics...

It's an analogy. Analogies by defination are not entirely exact and specific. I suggest you deal with it. I don't think anyone said "Voltage IS pressure", they said "Voltage is similar to pressure because the potential difference drives the current, just as the pressure drives the flow of...

Both Gravity and Electromagnetic interaction have speed. Their speed is the speed of light - the speed of their virtual particles if you like (Graviton and photon respectively). However the speed of current flow is the drift velocity of the electron. I think gravity waves are real gravitons...

So what happens and can this relate to the case of neutrons within neutron stars? Thanks.

I'm not exactly sure, don't take this as gospel, but I'd imagine that when they came closely packed, occupying similar space, that the constituent particles of He4 (neutrons and protons) are actually Fermions, so they would have to satisfy Pauli Exclusion Principle... For example, a Cooper...

So for a wave at latitude 45 degrees, with 5 maxima around a circle of longitude, and latitudinal width 5000km, superimposed on u= 5 m/s, I have tried to determine the speed of the wave relative to the ground. I used n= 5 (for 5 maxima), and L = 5000km. My value for beta is 1.6 x 10^-11...

Hi, I was wondering how to find the wavenumber of a Rossby wave? The information I have so far is speed of the wave is c = &\overline{u} - \frac{\beta}{k^2 + l^2}} where l and k are longitudinal/latitudinal wavenumbers, beta is df/dy and u is basic westward flow. I have determined the...

Umm, I'm pretty sure Hurricanes are at least thousands times more energetic than H-Bombs. I'm learning atmospheric physics, but oddly this question hasn't popped up. Hurricanes are cyclonic around low pressure regions. I don't think the H-bomb is going to affect this region much at all, it's...

I was just reading http://www.prahlad.org/pub/bearden/scalar_wars.htm E=tc^2 ? :smile: This guy needs to take a serious class in dimensional analysis before he attempts to bother himself with scalar weapons. Does he think Einstein just woke up one day and said "E=mc^2!" No, it was years of...

Just wanted to bump this just in case someone knows a book, before I need to hand my work in.

Hi, I am writing a thesis on Schumann Resonances, and my problem is that I can't find any publications mentioning it, except for J.D Jackson, Classical Electrodynamics. Does anyone here have any suggestions? Thanks.

Electricity is a very loose definition. Do you mean Current? Voltage? Charge? I wouldn't say light is carried by photons either. Rather, light/em radiation can be described in terms of photons. Also a photon is not matter. Matter has mass, and as far as we know, photons have no mass. So...

Too many. That's partly the reason I did a physics degree, to prove to myself I wasn't that kind of person.

Look at Chinese "Communism". Actually, it's not really communism is it?
