Requesting someone to clarify this. Thanks.

Is it that the notion of 'virtual photons' came into picture because of attempting to explain these interactions through pertubation theory? And is that why this explanation of interactions through photons are just for simple examples and cannot accommodate for explaining the reality, i.e. an...

Hello. One confusion regarding the explanation of electromagnetic [EM] interactions through photons. Conisder the water jug example given in this wikipedia http://en.wikipedia.org/wiki/Fundamental_interaction#Electromagnetism". It says - "if we place two such jugs a meter apart, the...

"What is the difference between a house and the bricks?" Who said there is?! And that is what I am trying figure out. But didn't want commit a mistake because of the shallow knowledge about quantum physics. The purpose of the thread is to clarify/debate whether the components and their...

Disclaimer - I am not a science grad student! As far as I have read, you are right. "Act of observation" doesn't stand for observations by a sapient human. In an electron double slit experiment, usually a photon is bumped to the electron to know its position/momentum. And that is how the "act...

Thanks for adding that info.

@Dickfore yah... colour has been discussed above, in the initial posts.

@tom.stoer - Thanks for confirming that. I asked this question with a particular philosophical curiosity. If the whole [e.g. proton] doesn't have anything of its own and can be explained by and in terms of the parts [quarks], then is there any whole? I didnt put the question with philosophical...

First of all, thanks for replying. When we consider color charge property, there is of course difference. But what I am interested in is the difference between these two at the intrinsic properties that define each of them. So can I say that there is no single basic property [at least that...

Hello. One basic question. What properites that quarks have which their "compound" forms [protons/neutrons] don't have and vice-versa? That is, a proton may have some property or characteristic and the quarks might not be having that. So something which is NOT available at the components...

@ZapperZ - Excuse. Will take care from future. @bigubau - I searched this forum and tried even google; but no luck! Though, I got links related to Rutherford's model and its drawback, I am not able to find the answer to my question. can you please point me to the resource or mention the reason...

Thanks bigubau for confirming & answering. Helped!

Hello. One doubt. How is the distance between the charged particles and the EMF between them get balanced out? That is, if I have a proton and electron, they attract each other, move towards each other and form a H atom. But going by this attractive force, they should approach each other...

Hello. > Is there any electromagnetic force of repulsion between two quarks? > And, hypothetically speaking [as independent quarks are not observable], could there be EMF of attraction between an electron and an independent quark? Actually, both the questions boil down to the following -...

Thanks for your reply. As you pointed out, yes... there would be topological difference. But I was not looking for that difference. Any idea on how to model these two states? Of course, I am not asking for the entire step-by-step procedure, but something to start with. From there, I till...
