    High School Nice Electrostatic Experiments

    Why not try this one:- (long back done by Sir Michael Faraday) Take a bowl(approx. 30 cm in diameter) pour water halfway.Now spprinkle some cumin seeds on the water surface(to make it look beautiful you could also use colored (small)bits of paper). Now charge an ebonite/plastic rod (by...

    Graduate Why don't atoms self-destruct?

    I suspect that this topic belongs to the "Beyond the SM" forum. Please post threads in right forums(as it creates confusion if not done so).

    Graduate Do Gravitational Fields Increase the Rest Mass of Protons and Photons?

    I know that the sum of the rest masses of the constituent particles,of ,say, hadron, doesn't equals that of the ensemble they make.But thanks for reminding.So is a proton modeled as a three body problem with the 'bodies' being quarks.Or... is it something more complex(like introduction of...

    Graduate Do Gravitational Fields Increase the Rest Mass of Protons and Photons?

    (Hey! I've corrected it now please spare me.It was just a typo.Now don't go on refraining it) I've a new question:- How are protons 'excited' (or the quarks within), is it a 3-body QM problem(I don't think so)?How is it related to proton's rest mass? Thanks in advance!

    Graduate Do Gravitational Fields Increase the Rest Mass of Protons and Photons?

    Oh.. Thank you very much. Hm.. then according to the basic convention if the rest mass of some known particle is increased(how?) then it is called something else(as I infer from the particle data).What I think here is that even if increase the rest mass of that particle,for example a hardon...

    Graduate Do Gravitational Fields Increase the Rest Mass of Protons and Photons?

    Sorry Sir Vanadium, but I didn't get your above post. What relation do "all protons being identical" have with "protons rest mass"? I'd be glad to know. Thanks in Advance!

    Undergrad Why do electric fields seem to be zero in conductors?

    Mr. Berko I'll answer the second part of your question. Yes the electron don't toally go and get collected on one side( when in electric field) as the whloe distribution will become absurd (as you've rightly stated that the lattice ions can't drift but this wasn't known at the time of Coulomb...

    Graduate Italian double slit electron experiment

    I wish what you said would be true(but it is not completely though).As I've spent weeks since the time when my study to give logical explanations for quantum mechanics and to disprove certain conjectures but failed each time. Yeah your suggestion(experimental setup) is really helpful as a study...

    Graduate What IS happening with photon frequency?

    GUYS nhmllr is right.Your discussions are taking him nowhere. nhmllr is here to learn and understand quantum mechanics and we are here to help him. And nhmllr to you would say the same what Dr. Feynman said to me (not literally 'said' as I read) that the concept of quanta of energy is clear to...

    Calculating Electron Energy with Uncertainty Principle: Homework Example

    One can derive the general uncertainity principle by using the standard deviation method of statistics. Here delta(x) and delta(p) are standard deviations. (delta(x))^(2)=|<x^(2)>-<x>^(2)| (delta(p))^(2)=|<p^(2)>-<p>^(2)|

    How does the voltage on the inductor change over time?

    SimpliciusH you need to practice trigonometry. I recommend Trigonometry by S.L. Loney to you (It's a must for you)

    Period and frequency of a lightwave

    Yeah menco, there is a calculation error and nothing else.

    Does Freezing Increase the Density of an Unknown Fluid?

    Yeah! bobred read the the statement of Archimede's principle carefully, you'll surely be able to solve then.

    Graduate Can Quantum States be Transferred without Knowledge of Initial Orientation?

    Sorry to state this Sir Harmony I'm not an expert.I just took up quantum mechanics few weeks ago. And K^2 I wasn't talking about quantum teleportation (by the way what is it?) I just gave what I interpret from quantum mechanic which is that the experiment which I perform at quantum level has a...
