    leptons could be unfundamental - they could be branes, which themselves could be made of "brane substance" which would be fundamental
    but in general terms they are fundamental, they are the smallest, basic

    i know you are a god but he may start getting confused.

    ok, fairenough

    in the standard model, leptons are fundamental.

    I have a head full of random and useless facts

    My daddy used to make me learn vast chunks of Shakespeare and stuff like that... Useless in everyday life, great in pub quizes!

    This spin thing seems silly. I get the "too hard for you to learn at college, so we totally lie to you" impression from college. What does it mean?
    Something to do with all those nasty quantum number things (I think it's the fourth quantum number of the electron) and has something to do with Pauli's Exclusion principle. Not really sure

    Can't say I watched/read Anglea's Ashes

    My daddy is about the least patriotic person I know - he certainly didn't go for the trying to make me sacrifice myself for Ireland routine!

    i had it on tape being read by frank mccourt (i listen to a lot of books on tape when I'm driving now. i feel much more well read..lol). it's worth a read/listen.. i think. i enjoyed the listening because obviously he does all the accents and stuff but if you are irish maybeyou would read it that way anyway.... if that makes sense!

    This is one instance where I preferred the film to the book actually... I liked it.

    i havent seen the film.. i dont watch many films.

    the last film i saw was girl with a pearl earring and then i read the book... I think they went well together - the film gives you a lot of atmosphere and it's about a very visual subject, but the book fills in what happens a lot more.

    cant be arsed to read through to see whether ti's been answered or not, but a positron is only mathematically an electron travelling backwards through time. We're pretty sure that it isnt an electron doing that, it's just the equivilent of. when an electron and positron collide and emit a gamma ray, it is NOT an electron emitting a gamma ray, bouncing backward through time thus appearing as a positron travelling forwards through time, although mathematically, this is sound.

    Surely at least two gamma rays must be released to conserve momentum...? :confused:

    Yeah, an electron and positron colliding produces a pair of gamma photons travelling in opposite directions.
