Rincewind Posted 6 March 2008 Posted 6 March 2008 The cat and the sparrow met one fine day just ast the sparrow was about to fly away The cat said 'Ah dinner you wont be going south' The sparrow replied 'don't swallow I've shit in your mouth.'
Daggers Posted 6 March 2008 Posted 6 March 2008 Relativistic quantum field theory has worked very well to describe the observed behaviors and properties of elementary particles. But the theory itself only works well when gravity is so weak that it can be neglected. Particle theory only works when we pretend gravity doesn't exist. . General relativity has yielded a wealth of insight into the Universe, the orbits of planets, the evolution of stars and galaxies, the Big Bang and recently observed black holes and gravitational lenses. However, the theory itself only works when we pretend that the Universe is purely classical and that quantum mechanics is not needed in our description of Nature. . String theory is believed to close this gap. . Originally, string theory was proposed as an explanation for the observed relationship between mass and spin for certain particles called hadrons, which include the proton and neutron. Things didn't work out, though, and Quantum Chromodynamics eventually proved a better theory for hadrons. . But particles in string theory arise as excitations of the string, and included in the excitations of a string in string theory is a particle with zero mass and two units of spin. . If there were a good quantum theory of gravity, then the particle that would carry the gravitational force would have zero mass and two units of spin. This has been known by theoretical physicists for a long time. This theorized particle is called the graviton. . This led early string theorists to propose that string theory be applied not as a theory of hadronic particles, but as a theory of quantum gravity, the unfulfilled fantasy of theoretical physics in the particle and gravity communities for decades. . But it wasn't enough that there be a graviton predicted by string theory. One can add a graviton to quantum field theory by hand, but the calculations that are supposed to describe Nature become useless. This is because, as illustrated in the diagram above, particle interactions occur at a single point of spacetime, at zero distance between the interacting particles. For gravitons, the mathematics behaves so badly at zero distance that the answers just don't make sense. In string theory, the strings collide over a small but finite distance, and the answers do make sense. . This doesn't mean that string theory is not without its deficiencies. But the zero distance behavior is such that we can combine quantum mechanics and gravity, and we can talk sensibly about a string excitation that carries the gravitational force. . This was a very great hurdle that was overcome for late 20th century physics, which is why so many young people are willing to learn the grueling complex and abstract mathematics that is necessary to study a quantum theory of interacting strings.
coale39 Posted 6 March 2008 Posted 6 March 2008 Who is that? Not Pam Ayres? is it? Do you know what? I ant got the foggyist.
coale39 Posted 6 March 2008 Posted 6 March 2008 Daggers String Marlarky That post is meaningless without pictures of chebs.
Rincewind Posted 6 March 2008 Author Posted 6 March 2008 Is Daggers post topic related? I haven't got time to read it. I finish at 3am.
Daggers Posted 6 March 2008 Posted 6 March 2008 Is Daggers post topic related? I haven't got time to read it. I finish at 3am. Short answer Ken - yes, it explains your threads perfectly
coale39 Posted 6 March 2008 Posted 6 March 2008 And the 'Most Intricate Tan Lines' winner is... What tan lines.... Should get back on with that essay now really. Chewing it wont get me a 2:1.
Rincewind Posted 7 March 2008 Author Posted 7 March 2008 I sit all alone in an office all night wondering what to do My mind goes blank My head spins round And thats when I think of you. Your rotten teeth that creak in the dark when you kiss me goodnight Your under-cooked roasts That taste so vile Make me so glad I work at night. Then the memories come flooding back And the reason I married you Your fortune will be mine when you are gone So darling please die SOON.
Rincewind Posted 7 March 2008 Author Posted 7 March 2008 Autumn leaves that crinkle underfoot The misty sky at night The gale force winds The thunderstorms Such is a nightguards life. Winter snow three feet deep Working on Xmas night The icy paths The doublethick coats Such is a nightguards life Spring birds singing a mating call Owls that hoot at night Flowers blooming Gardens of colour Such is a nightguards life. Summer evenings bright and clear Patrols in short sleeves at night Cheese salad meal Unofficial cold beer Such is a nightguards life.

The People's Hero Posted 7 March 2008 Posted 7 March 2008 That post is meaningless without pictures of chebs. That is beautiful.
BigGibbo Posted 7 March 2008 Posted 7 March 2008 Do you regularly get rather pisseh & start random threads on here?
The People's Hero Posted 7 March 2008 Posted 7 March 2008 That post is meaningless without pictures of chebs. Right, someone fill in for me at work. I'm taking this minx to bed. And I won't be back for 5 (YES FIVE - COUNT EM!!!) minutes.
The People's Hero Posted 7 March 2008 Posted 7 March 2008 Not so good. I liked the previous one better.
Master Fox Posted 7 March 2008 Posted 7 March 2008 Not so good.I liked the previous one better. It wasn't to compare.
Rincewind Posted 7 March 2008 Author Posted 7 March 2008 I never started this poetry lark. T'was the Maidstone one I'm going out after this post So my input for now is done.
The People's Hero Posted 7 March 2008 Posted 7 March 2008 Maidenhead? Blimey. I've gone up.. err down in the world.
The People's Hero Posted 7 March 2008 Posted 7 March 2008 Maidstone through and through me. AN M AND AN A AND AN I AND A D, AN S AND A T AND AN O - N - E, M - A - I - D - S - T - O - N - E WE ARE MAIDSTONE UTD. FC!
