    When will fusion power be economically viable?

    agreed, i personally feel the later is more probable. :( Thanks for the info on fusion power stations.

    When will fusion power be economically viable?

    Can anyone here tell me how long it will be (roughly) until hydrogen fusion power stations are producing energy at economic rates? it can't be far off can it? thx

    Voltage, Current & Amps: Explained

    Just for fun... in everyday household appliances the 'net' movement of electrons through a wire is just millimeters per second! quite a paradox seeing as we are used to electrons traveling very quickly...

    The Brazil Nut Effect: Explained!

    This is used to great effect in coffee percolators. The coffee is placed in a compartment above the water. The water is boiled and the vapour will travel to the top and condence back to a liquid. This liquid runs though the coffee back to the bottom taking with it any disolvable coffee...

    Atoms, Black Holes and Singularities: A Historian's Questions

    This isn't really my area but i once read sumthing along the lines of... when a star shrinks to a singularity its gravitational pull is such that is warps space-time into a loop. To me this means that it can have mass but no volume. Also it should have infinite density directly because it has no...

    Is String Theory the Limit of Our Understanding?

    I share your thoughts Chronos! but i don't think that it discredits it just makes it seem even more unlikly. Thanks marcus for all the quotes, they are very interesting. I read back though my original post and i think i miswrote that part about acceptance. I am aware that it isn't accepted as a...

    Is String Theory the Limit of Our Understanding?

    if string theory is so brillient how come i can't find any info on how string theory says beta decay MUST happen. I keep asking and getting the answer "string theory does not yet deal with that level of detail". I mean, how can this be?? how can a theory be so widly accepted and not explain the...

    Leptons produced during beta decay

    so why were quarks once considered fundamental if they can decay into other particles? it seems to me that they must be made of constituent particles for beta decay to happen in the way that you described (assuming the w+,w- and z0 vector bosons have rest mass > 0). which they must do to...

    Leptons produced during beta decay

    i know I've asked this before and please delete it if i can't post it again, but i didnt get an answer last time and it seems to be to be a fundamental problem in my understanding. does string theory answer the question of how to leptons can be produced from one quark? if i undserstand string...

    Photon Absorption by Electrons: Physical or Mathematical?

    ok so we have to consider the structure of spacetime... does string theory answer the question of how to leptons can be produced from one quark? if i undserstand string theory at all i believe it states that each fundamental particle is a vibrating string. I still can't work out how one string...

    Question: Is the statement regarding the sound frequency true or false?

    as for the 'funky ambulance', in the UK we have ambulance...nothing new, but they have 2 or 3 different sirens. first they do have that 'whhheeeiiiooo' noise and the one that has 2 tones. Both seems to work well as far as my sound perception goes! i can still tell there is a dopler effect with...

    Photon Absorption by Electrons: Physical or Mathematical?

    can i add something in here?? not an answer but a new question. you say that protons structure can be determined? I've always wondred how an electron and electron antineutrino can be emited from a neutron during beta decay to form a proton. i understand there must be conservation of mass and...

    Is Fermonic Spin Different from Particle Polarisation?

    ok thanks, can you give an explanation of why in any quantum energy level there are two 'types' of electron, s_z=+\frac{1}{2} and s_z=-\frac{1}{2} and yet i was told all 'naturally' occurring electrons spin to the left!? was i being lied to or am i missing something? :rolleyes: is it only...

    What speed do subatomic particles travel around the nucleus?

    being out by a factor of 10 isn't bad for me ;-) my sketchy mathes is always a little wrong! can anyone come up with a real answer? or shall i search google? Tom
