Modern and Theoretical Physics

H'ya guys! (and gals!) This is a question that has been bugging me for some time. I can't find an answer online, and neither in the books I posses. So I'll ask the experts: The source of EM field is the EM charge density (J, the electric currents and charges). My question is, given that QFT theorizes that electrons are waves in an electron-positron quantum field, let's call that field [latex]\psi[/latex] - what are the sources of [latex]\psi[/latex]? Does it have a source at all? or is the source just zero? (I'm thinking about this as the analogous of the "divergence" of [latex]\psi[/latex]) Also, is this the case with other 'matter' fields? Thank you!

Electromagnetic induction Magnetic induction Magnetic induction I believe is used for transformers Electromagnetic induction is used for antennas/sending em radiation signals and EMP devices etc

binding energy and rest mass

Does a neutron emit/produce radiation like charge particles do when they accelerate? I assume they produce or have some sort of thermal energy since nothing is at absolute zero

that is practical and is not near the speed of light (because then i need to transform equation) please insert beginning and ending velocity and find acceleration for it thanks

Half-wave antenna dipole antenna vertical antenna

I understand that an accelerated charge produces/emits radiation (I have looked at lamors formula/poynting vector etc for the way this occurs) but I am wondering what does it take to get a certain/specific frequency of em radiation to be emitted/produced by the accelerated charge? Is the frequency of em radiaton emitted proportional to acceleration?

What would be the most effective method of disabling all electronics in a building without going in it? Using any kind of technology that you can obtain? A good example would be a portable EMP generator, which will be powerful enough to knock out (temporarily) my neighbors electricity and portable devices. Another example would be a device that sends an electric current or an electric field through a framework that would cause damage to the circuitry of the electronics.

How do scientists see it if it doesn't produce radiation theoretically since it does not have a positive or negative charge. What affect does not having a charge make a neutron differ from an electron and proton?

The antenna's radio stations use to produce radio waves, can it be customized to emit radiowaves/gamma rays or if one simply increased frequency?

I would like to find the acceleration of an electron moving in a straight line from a point a to point b

What are the limitations of lamor's equation for finding the power emitted from a charge formula --> P = (2/3) * (q^2 * a^2/c^3) q = charge a = acceleration c = speed of lightt I was also told that lamor's equation must be "transformed" in order to find the amount of power emitted from a charge moving close the speed of light (something about relativity) - so how does one "transform" this equation for relativity The information i got was from this link, it is pretty simply to understand http://www.cv.nrao.edu/course/astr534/LarmorRad.html

Letter "v" with a dot on top of it? I was told it means acceleration but not sure why or if correct

The formula I am using says that it is a non-relativistic equation and to calculate velocities near the speed of light I have to transform it somehow to make it relativistically accurate (something like that)

A charge emits in radiation what it has as its relativistic mass, rest energy of particles never change, only with its anti-particle?

Please explain thanks with analogies, I have hard time understanding from wikipedia, more practical/real life example would be good thanks

We (I at leat) use to think of information as data that one needs to achieve something, for instance to increase knowledge. So in this view there is no objective 'free-floating' information: there has to be a need, a question first. That is, there has to be someone / something to interpret the information. For example: "at 2 pm" is not information, unless I want to know when the bus to X leaves. Also, a piece of text (book) only contains information if there is someone to read it; a book on a shelf is just ink and paper, until someone opens it and starts to read. So in my view information is relational and perspectival; presupposes a relation to an observer who wants to k…

Why anti-hydrogen inducted by electromagnetic force? To confine them or other acts. Normal Hydrogen atom doesn't interact with.

... That our universe (meaning our understanding of this expanse of space populated by countless galaxies to an edge to where we can no longer observe) is actually a microscopic piece of (possibly) a living organism,existing in its own exponentially larger universe to ours? And that that implies it too is a microscopic piece of a larger organism and so on, implying that we too possibly contain infinite-exponentially smaller "universes" within us? Pat.

A charged particle (electron/proton) is said to produce/emit radiation I understand also that matter is energy itself, so does the acceleration of the charge convert the mass of the charge into radiation (that is how I will use the world emission for this context) or is it simply the oscillation of the charge that produces radiation waves? Thank you in advance

thank you in advance, i understand that all particles have "thermal motion" i believe (something along those lines) and thus they are always emitting radiation (even neutrons? <--- yes that is a question so answer that too please if you can) as long as it is above absolute zero...... and thermal motion means thermal emission of radiation (thermal radiation)

Thank you in advance, detailed explanation would be great or a good link you can find (besides wikipedia )

For the equation e=mc^2 which energy is it referring to, I have read that nuclear binding energy is the energy difference between a nucleus as a whole and the separate components = deltamc^2 so has the energy of the actual matter which i think is a form of energy actually been used/converted to energy or is it simply some abstract thing we call "binding energy"

why is this so? please explain in detail if possible

How does radiation help in the production of steam (from water) what are the formula/s involved to find out let's say 1 gram of water into steam?
