    Hi Windrose, I see I had you confused with Zebadee (when I asked you if that was your son that figured that out - see her post below). I don't know yet. I am up to my eyebrows in internet security. I just downloaded and installed SpyBlaster. You know all those annoying advertisments on FC? They are powered by Macromedia Flashplayer. SpyBlaster enables me to stop them from flashing in my face on FC! I am looking at temporary ID creation with temporary email addresses before going on more forums. (BugMeNot software- search it) I am not gone from FC yet. Tonight I posted twice to a FC private post on Kundalini/CSF/AUM/pranayama etc. I miss talking to you too.

    Where else except FC could I read what you write, Mike? I miss you posting here...

    My background is in Electrical Engineering but for the past few years I have been studying QFT and GR mathematics leading to it. The particle physics below is childs play.

    Particle accelerators cannot be built powerful enough to produce the most energetic particles like cosmic rays so particle physics more and more is turning to space to understand subatomic physics. I have been fortunate enough to have resources that enabled me to learn things like nuclear physics and astrophysics but it is actually more disturbing to me to know how much I don't know! It gets more and more mathematical/that is my frontier.

    Just a question of curiosity, what do you do? and what degrees do you have?( im guessing astrophysics and astronomy :P)

    Don't be confused by what your teacher said. He or she is only injecting the fact that electron location is a statistical wave function and in the jargon electrons don't 'jump' from one orbit to another either but 'appear' there but it serves no purpose to talk about it in this way unless and until you actually attempt to determine the probability of the electron at a location. It is best just to think of the Bohr quantum atom. I see no reason to talk about electrons traveling through the nucleus either. Protons and neutrons are made of up and down quarks that don't feel the electric force nor do electrons feel the color force that holds quarks in orbit inside a proton or neutron. There are 3 types of beta decays. As I said in the thread:

    Neutrons are composed of 2 down quarks of charge -1/3 and one up quark +2/3. A lone neutron can decay into a proton (which is 2 up quarks of charge +2/3 and one down quark of charge = -1/3) and an electron and an anti electron neutrinos by the -W weak force boson force carrier and is called Beta-minus (radioactive) decay. This decay can also happen when the neutral atomic mass of the original atom is larger than that of the final atom. When you have more neutrons than protons. When a minus beta decay happens the -W boson of the weak force operates on the neutron to create a proton and emitting an electron and electron antineutrino. The 3 quarks inside the neutron are
    -1/3 + -1/3 + 2/3 = 0 net charge. When -W operates specifically on one of the down quarks turning them into an up quark. A proton is +2/3 + 2/3 -1/3 = +1 net charge.
    So neutrons are not protons + electrons. Neutrons are made up of 3 quarks. Neutrons are not fundamental particles like quarks and electrons.

    They don't teach particle physics to undergrads generally but basic particle physics is very simple. I have a lot of books on these subjects but the best I have ever seen is Understanding the Universe from Quarks to the Cosmos by Don Lincoln Fermilab particle accelerator scientist and The Particle Odyssey by Frank Close et al. (actually Lincoln had a mistake on Beta Decay in his book which I contacted him on and he said that I was the first to find it and it was his biggest blunder in the book so far).

    For a good read on FC on quarks see my post Bottled Lightning or We are Mostly Empty Space. Cheers!

    hahha, i attempted , i understood the majority but i didn't understand the epsilon not :\

    OHHH!! and i was talking about quantum physics to my teacher during a class and he told me that electrons could travel through the nucleus, well i though yes its possible since the gaps in the nucleus is massive and the likely hood of a collison is minimal, is there a possibility that an electron can collide with a proton in the nucleus? would this result in a similar effect to that of a nuclear decay?

    thanks again

    Hey mate, i was just viewing the topic about the Hydrogen atom, was quite fascinated haha, just wondering what book are you using, im quite interested in Quantum Physics (considering doing it in uni).

    Cheers!

    "I Guess its time to bugger out of philosophy for awhile and allow you all to commiserate. Alone as usual." please don't leave yet i appologize for the time my response is taking but i'm trying to give as in depth a reply as you have given us

    I am glad to see that you have made your presence here existent again. You are the clow, the unwilling clown of the batch here. Any time anyone here gets made fun of, or insulted, or mocked, it is almost certain to be you. You are sad and funny.
