Dog Posted January 25, 2009 Share Posted January 25, 2009 [quote user="Bugbear"]To measure the position and the speed of a certain particle we need light or another radiation. When we use radiation with a long wavelength the position is inexact, but the speed is quite exact. When we use radiation with a short wavelength the position is quite exact, but the speed is inexact. This means that when we want to measure one of these things exact, we cannot measure the other thing exact, too. Some things which are explained in nuclear physics with a simple pattern cannot be explained in quantum physics so easy, too. We have this problem with the Bohr atom model. In real there are not any electrons which fly around the atomic nucleus, but you imagine that they are on certains energie levels. In this situation it is also impossible to say exact where an electron is. So here we find Heisenberg's uncertainty relation, too. But there are so called orbitals where it is very probable that there is an electron, but it is never sure. In quantum physics we have got only probabilities..[/quote]Are you taking ether into account? Link to comment Share on other sites More sharing options...

I can see the parallels. So the thinner the probable distribution is for a position the wider its momentumForgive my shakey grasp of quantum physics. My father unexpectedly phoned today excitedly telling me about his research on Golden Chains after five minutes I still thought he had bought a posh new toilet chain. He and one of my brothers are deeply into physics and astrology at the momentum.I just ask them to give me a precis when they have finished.Say la vee as they say in Globish.

Bugsy Posted January 25, 2009 Share Posted January 25, 2009 The story of Schroedinger's cat (an epic poem) May 7, 1982 Dear Cecil: Cecil, you're my final hope Of finding out the true Straight Dope For I have been reading of Schroedinger's cat But none of my cats are at all like that. This unusual animal (so it is said) Is simultaneously live and dead! What I don't understand is just why he Can't be one or other, unquestionably. My future now hangs in between eigenstates. In one I'm enlightened, the other I ain't. If you understand, Cecil, then show me the way And rescue my psyche from quantum decay. But if this queer thing has perplexed even you, Then I will and won't see you in Schroedinger's zoo.— Randy F., Chicago Dear Randy: Schroedinger, Erwin! Professor of physics! Wrote daring equations! Confounded his critics! (Not bad, eh? Don't worry. This part of the verse Starts off pretty good, but it gets a lot worse.) Win saw that the theory that Newton'd invented By Einstein's discov'ries had been badly dented. What now? wailed his colleagues. Said Erwin, "Don't panic, No grease monkey I, but a quantum mechanic. Consider electrons. Now, these teeny articles Are sometimes like waves, and then sometimes like particles. If that's not confusing, the nuclear dance Of electrons and suchlike is governed by chance! No sweat, though--my theory permits us to judge Where some of 'em is and the rest of 'em was." Not everyone bought this. It threatened to wreck The comforting linkage of cause and effect. E'en Einstein had doubts, and so Schroedinger tried To tell him what quantum mechanics implied. Said Win to Al, "Brother, suppose we've a cat, And inside a tube we have put that cat at-- Along with a solitaire deck and some Fritos, A bottle of Night Train, a couple mosquitoes (Or something else rhyming) and, oh, if you got 'em, One vial prussic acid, one decaying ottom Or atom--whatever--but when it emits, A trigger device blasts the vial into bits Which snuffs our poor kitty. The odds of this crime Are 50 to 50 per hour each time. The cylinder's sealed. The hour's passed away. Is Our pussy still purring--or pushing up daisies? Now, you'd say the cat either lives or it don't But quantum mechanics is stubborn and won't. Statistically speaking, the cat (goes the joke), Is half a cat breathing and half a cat croaked. To some this may seem a ridiculous split, But quantum mechanics must answer, "Tough @#&! We may not know much, but one thing's fo' sho': There's things in the cosmos that we cannot know. Shine light on electrons--you'll cause them to swerve. The act of observing disturbs the observed-- Which ruins your test. But then if there's no testing To see if a particle's moving or resting Why try to conjecture? Pure useless endeavor! We know probability--certainty, never.' The effect of this notion? I very much fear 'Twill make doubtful all things that were formerly clear. Till soon the cat doctors will say in reports, "We've just flipped a coin and we've learned he's a corpse."' So saith Herr Erwin. Quoth Albert, "You're nuts. God doesn't play dice with the universe, putz. I'll prove it!" he said, and the Lord knows he tried-- In vain--until fin'ly he more or less died. Win spoke at the funeral: "Listen, dear friends, Sweet Al was my buddy. I must make amends. Though he doubted my theory, I'll say of this saint: Ten-to-one he's in heaven--but five bucks says he ain't."— Cecil AdamsBest explained in a french accent over a glass or two of Cointeau..

Dog Posted January 25, 2009 Share Posted January 25, 2009 In my humble opinion your chance of getting past first base using Shrodingers cat as a chat up line is confused. I realise you wanted to acheive the superposition state but this may prove complex.For example, if your femme fatale can be in position A and position B, she can also be in a state where it is an amount "3i/5" in position A and an amount "4/5" in position B. To write this, I'd usually say:V= three over 5i)A+four over five(B)In the description, only the relative size is of importance.Please tell more how you got on using this theorem?I am having trouble visualising it.
