    The idea of the positron's existence?

    I think the best answer is to say the positron is just a fact of the equations that wasn't apparent in the non-relativistic approximation but appears in the more accurate Dirac Equation. Someone could post here correcting me and saying that the inclusion of relativity is more fundamental to...

    The idea of the positron's existence?

    The easy way to explain this is that Dirac was figuring out his 'Dirac Equation', which in a really hand-wavy way can be called a relativistic version of the Schrödinger equation which preceded it. Dirac noticed that his equation (governing electrons) not only allows for the normal electron...

    Several Queries Concerning Some Science Stuff

    The Higgs doesn't really carry a force. The Higgs field is what gives particles their mass, the graviton (if it exists) is the force carrier for gravitation.

    Higgs particle is 'found'

    Well generation matters, there are certain interactions which only work within a given generation of matter (I should know which, but I don't- I think the weak nuclear force). And there 'wouldn't be a problem' (at least not as far as I know), but any sort of 4th generation isn't included in the...

    Higgs particle is 'found'

    They said that best case scenario it would be by the end of the year.

    Higgs boson and neutrino mass

    How do you measure the mass difference without knowing which is more massive?

    Higgs boson and neutrino mass

    Fair, but my point it still valid. Assuming the tau is the other you mention might not have mass. Is it simply the lack of experimental evidence that illuminates this possibility? Or something else?

    Higgs boson and neutrino mass

    Well both experiments pegged a probably mass of the new particle (remember we don't know it's a higgs yet) at about 125 GeV (I think ATLAS' best guess was a little bit higher at about 126 GeV. This is because the decay modes they were looking at did not involve neutrinos. Even if they did...

    Higgs particle is 'found'

    This particle they've just announced is heavier than all fundamental particles apart from the Top Quark, which is about 35 GeV heavier. Both are far heavier than the proton, which is far heavier than the electron. The reason heavier particles are tougher to find is that the way they...

    Higgs particle is 'found'

    In the press conference they said that with the various uncertainties the two detector's estimates for the Higgs' mass were definitely compatible. Also they said that they are planning to extend this year's science run by two or three months in order to facilitate more data gathering, which...

    Higgs particle is 'found'

    So in actuality I agree that you are totally correct, I would have worded it better were I thinking about more. But I still think that at a layman's level what I said is fine. They have found a signal indicative of a new particle. And the likelihood of this signal being caused by the...

    Higgs particle is 'found'

    You don't have a proof through experiment. ATLAS and CMS have a 99.9999% certainty that there they have found a new boson with a mass of 125 GeV- consistant with the Higgs. But there are several variants of the higgs. This is just the beginning: the discovery of a new particle. The future is...

    Higgs particle is 'found'

    I'm pretty sure I heard someone say that they knew it was a boson, maybe I misheard.

    Higgs particle is 'found'

    Can someone explain to me how they know this particle is a boson?

    Only wave, no particle

    Not in the way I think you are meaning, no. Then again the closer you look the more the words 'wave' and 'particle' get blurry.

    Interested in particle physics, having trouble understanding.

    Assuming you're not interested in the math of it (at least not yet!), you can pretty much jump in. However you should be careful not to jump in too fast, or else you'll be swamped by things you won't be able to understand. For starting books, I really don't know any good ones, the first book I...

    Interested in particle physics, having trouble understanding.

    You're obviously interested in the subject, which is always a great thing. I think its great that more people are being exposed to Modern Physics, however the biggest problem is that people come in expecting that they will be told things, they will think about it, and they will make sense. This...
