    Graduate Need explanation of theorems on Uniform continuity

    I'm taking my first course in Analysis, and we learned a couple of theorems about Uniform Continuity. I have been able to visualize most of what's been going on before, but I need some help with the following: E \subseteq ℝ, f: E \rightarrow ℝ uniform continuous. if a sequence xn is Cauchy...

    Graduate Is the Photon Really Its Own Antiparticle?

    A particle that is it's own anti-particle is called a Majorana particle (and is elementary). (http://en.wikipedia.org/wiki/Majorana_particle) Currently, only Majorana bosons are known to exist, although, the neutrino might be a Majorana fermion.

    Undergrad Why is fusion more efficient than fission?

    Assume the fusion of Deuterium (H2) and Tritium (H3) (isotopes of hydrogen having, respectively, one neutron and two neutrons). They can be fused together into a single Helium-4 atom and a free neutron. The binding energy of Deuterium is: 2224,52±0,20 keV (Wikipedia) The binding energy of...

    Graduate Are quarks as sub-atomic as it gets? necessarily?

    I actually believe that the Rishon model is quite an interesting theory. It's based on the preon model, but has some differences which make it a lot more plausible.http://www.weizmann.ac.il/home/harari/files/Nuclear_PhysicsB_Vol204.pdf (1981 paper)...

    Graduate How Can We Visualize Proton Decay and Its Implications in Particle Physics?

    As far as I know, no, R does not come from Rishon or Rishon value. I found this redirect, but it's not really helping, I guess. ( Unless the R comes from matteR. :P ) http://en.wikipedia.org/w/index.php?title=Matter_parity&redirect=no EDIT: I spotted this: On the WIKIPEDIA page on X and Y...

    Graduate How Can We Visualize Proton Decay and Its Implications in Particle Physics?

    I found that just as striking as you did, then I learned of the Rishon model (and the expended Harari-Steinberg model). There's quite a few neat papers on it on the net. http://www.weizmann.ac.il/home/harari/files/Nuclear_PhysicsB_Vol204.pdf (1982 version)...

    Graduate How are W Bosons Formed in Beta Decay

    Neutron decay works this way: https://upload.wikimedia.org/wikipedia/commons/8/89/Beta_Negative_Decay.svg A single down-quark decays into an up-quark and sends out a W- boson to compensate for the charge difference (since the conservation of charge must be kept). Quickly afterwards, the W-...

    Graduate How Can We Visualize Proton Decay and Its Implications in Particle Physics?

    That picture explained it pretty well, thanks for that! But I don't see how B-L is conserved in the process: u+u+d: B=1; L=0; B-L=1 X+d: B=1/3 + ?; L=?; B-L=1 e++anti-d+d: B=0; L=-1; B-L=1 What are the values of B and L in the middle step?

    Graduate How Can We Visualize Proton Decay and Its Implications in Particle Physics?

    Hm, that's not quite what I meant, but that's interesting. I've never heard of B-L conservation. In the given process, how would B-L be conserved? I'm aware of the color conservation, but I meant that as an alternative to quark and leptonnumber conservation, there could be some kind of...

    Graduate How Can We Visualize Proton Decay and Its Implications in Particle Physics?

    I'm aware of it being a hypothetical process, I was just curious how exactly it would have happened (because there's no conservation of lepton and quarknumber). Can an X-boson break this law in some way under some condition? EDIT: The way it looks to me is that the only real laws of...

    Graduate How Can We Visualize Proton Decay and Its Implications in Particle Physics?

    Hello there, I was just reading some articles on Wikipedia.org and found an article on proton decay. I will quote a part of it: How would that be visualized? I've got a basic understanding of particle physics, but these concepts seem rather advanced, yet, I insist on wanting to understand...

    Graduate The Outcome of W+ and W- Boson Collision

    I was just wondering, what would happen when a W+ boson and a W- boson collide?
