I have a question, if a photon is exchanged between the two electrons as in the diagram, why is it that the e- emitting the photon recoils only when it is close to another e-? Or, why is it that it emits a photon only when it come close to another e-? This doesn't make sense to me as according...

Newton's third law.

If you drop two pebbles in a pond, the receding waves travel through each other and reach the other sides of the pond. If 6 pebbles are dropped each individual resultant wave are still there and are just traveling through each other, they don't add up together and become one wave. Now instead...

What do you think of this? My guess (with my limited knowledge) is this is what will happen.

do you know how gravity works? I suggest you do some research with that first before you continue. You may think you know but uh, i don't think you do.:rolleyes:

Were those statistics based on PHD Graduates or both PHD and undergrads?

thanks for the replies:smile:

This is an article about some scientist who claimes he is/will be able to see and hear into the past. He claims in 20 years we'll have the technology to "talk" to ourselves in the past, say at our desk 30 min earlier and pass on instruction "verbally" through whatever means he claims to...

Thanks for that, I had a feeling it was going to be a lot more complicated then to get a simple layman explanation. I guess that's a good thing as I can ask questions and get a (hopefully) deeper understanding of the process. I haven't studied wave functions in QM so I'm having difficulty...

I'm having trouble understanding how the exchange of particles, wether it be in weak, Em, or Stong interactions, can cause an attraction between matter particles. Or how glueons produce such a stonger interaction with the strong force then say photons in the EM force. Can somone post a link or...

thanks man, I am a little lost as to how i incorporate the radius, but ill figure it out :smile: thanks

sorry, i calculated surface temp to be 4990k the question says turns to He (of atomic mass # 4) i was just hoping for a formula i would be able to work with as i don't kow where to begin, but ill give the radius too if you want all the info. r=7.02*10^8 m anyone able to help this...

Hi, I am having trouble with the last question in my assignment. It's on blackbody radiation and total power per area and whatnot. those questions i was able to do fine, however when i came to this problem i was a little lost.. here it goes, i'll type the whole thing out.. "The most...

great! thanks a lot for the help :smile: -Neil

alright thank you :smile: but do you mean u = root ((mc^2/E)^2(c^2) + c^2) but actually u = root (c^2 - (mc^2/E)^2(c^2) ) :confused:
