Why is it that quantum fields interact? How do they do this? Does every exitation of any field affect all other fields?
I'd appreciate an explanation that uses as little math as possible, I don't have a science background.
First of all, thanks for the excellent resources and good answers. I'll be spending a bit of time chewing through them and discussing what I don't understand with my friend when he's back. From what I can tell so far, though, it seems digestible :)
Secondly, I apologise for asking a question...
Yeah, I suppose asking on the Internet is not the best approach. As mentioned before, I'm no physics student. In fact I'm nothing more than a photographer, but I think understanding how the universe we inhabit works and why it exists is an important and incredibly interesting part of the human...
You're right, I'm not understanding this thoughly. Is there some recommend reading or perhaps a book or two I should read that will help me get my head around this and lay the groundwork for a proper understanding before I come back and read your answer again?
Thanks for the quick and good answers! I'm not entirely there yet, though. Perhaps if you could explain this hypotetical to me I would understand:
Say we are in a universe with properties just like the properties of our own universe, but there are only two planetary bodies in it, and no other...
I don't entirely understand. I should disclose that I have no formal education in science or physics. I'm just quite interested in the universe and how it works, and I'm attempting to wrap my head around these things without a good educational background on the topic. So perhaps you can help me...
Space is expanding, which separates objects from each other in space. Won't this add potential energy? Doesn't this violate the law of conservation of energy? But if it does not, how can space be added without adding potential energy?
Excellent, thanks for the answer!
So that means the U235 fissions at the moment of impact with the neutron, and never gets a chance to turn into U236? (Except for 18% of the time?)
Because from what I'd understood from this it first turns into a U236 atom, then almost instantly fissions into...
First of all, let me say I'm not a physicist, an undergrad, study physics or have any particular education surrounding physics. I'm actually simply a photographer with a special interest in science - so if possible, keep any answers simple.
Right, so I was reading about the fission of U235, and...
