19 Jul 02 - 08:26 PM (#751357) Subject: RE: Shroedinger's Cat From: cyder_drinker Schrödinger's cat's a mystery cat, he illustrates the laws; The complicated things he does have no apparent cause. He baffles the determinist, and drives him to despair; For when they try to pin him down--the quantum cat's not there! Schrödinger's cat's a mystery cat, he's given to random decisions; His mass is slightly altered by a cloud of virtual kittens; The vacuum fluctuations print his traces in the air But if you try to find him, the quantum cat's not there! Schrödinger's cat's a mystery cat, he's very small and light, And if you try to pen him in, he tunnels out of sight; So when the cruel scientist confined him in a box With poison-capsules, triggered by bizarre atomic clocks, He wasn't alive, he wasn't dead, or half of each; I swear That when they fixed his eigenstate--he simply wasn't there!

19 Jul 02 - 08:50 PM (#751359) Subject: RE: Shroedinger's Cat From: Gray D What I can't understand is that I opened a box the other day and there was no cat in it at all. Alive or dead. At least, I don't think there was. But I'm not sure. |

20 Jul 02 - 05:44 PM (#751732) Subject: RE: Shroedinger's Cat From: Amos Let's hope it isn't half-dead, CS!! But I think that's molecular, not quantuim phenomena you're observing. If these guys with their darned eigenstates were half as good as they are cracked up to be they could devise a cat-box that emptied itself every time you observed it!! Now that would be a nice piece of applied science! A |

21 Jul 02 - 01:29 AM (#751894) Subject: RE: Shroedinger's Cat From: Wincing Devil I can never keep Schrodinger's cat and the Heisenberg Uncertainty Principle straight. They both seem to state that by measuring or observing something, we change it. Stick a thermometer in a glass of watter, the thermometer will affect the temeratrure of the water so you will never truly know what the temerature of the water was befor you measured it. It's late and all this thinking is making my brain hurt. I'm going to bed so I can getup early tomorrow, put on funny clothes and do some 18th century shopping. |
21 Jul 02 - 04:15 AM (#751907) Subject: RE: Shroedinger's Cat From: Nigel Parsons WD: the thermometer thing is no problem, first you heat (or cool) the thermometer to the temperature of the water! Of course, first you need to know the temperature of the water, so.... Damn, failed again. Nigel |
21 Jul 02 - 05:52 AM (#751922) Subject: RE: Shroedinger's Cat From: Dave Bryant Perhaps we could try Shroedinger's experiment with an anonymous GUEST - I don't think anyone would be interested enough to ever open the box - we'd all rather leave GUEST in a state of limbo ! |

It's orbiting at 19 miles a second, So it's reckoned, A sun that is the source of all our power. The sun and you and me and all the stars that we can see, Are moving at a million miles a day, In an outer spiral arm, at 40,000 miles an hour, Of a galaxy we call the Milky Way. Our galaxy itself contains 100 billion stars, It's 100,000 light years side to side, It bulges in the middle, 16,000 light years thick, But out by us it's just 3,000 light years wide. We're 30,000 light years from galactic central point, We go around every 200 million years, And our galaxy is only one of millions of billions, In this amazing and expanding universe..." E. Idle |

07 Apr 04 - 11:11 AM (#1156614) Subject: RE: Shroedinger's Cat From: HuwG The missing last verse to E. Idle's "Universe" song, from the Python film, "The Meaning of Life": The universe itself keeps on expanding and expanding In all of the directions it can whizz As fast as it can go, the speed of life, you know Twelve million miles a minute and that's the fastest speed there is So remember when you're feeling very small and insecure How amazingly unlikely is your birth And pray that there's intelligent life somewhere out in space 'Cause there's b****r all down here on earth. **** In a BBC programme devoted to the Python's music, Mr. Idle accompanied himself on the guitar, while singing this. Neither I, nor most of the guitarists I know, could follow his fingers as they attacked the neck of the guitar. Nor do many of us have his singing voice's register. However, I sometimes do this song in informal company as: Just [G]remember that you're [D]standing on a [C]planet that [G]evolving, And revolving at nine [C]hundred miles an [D]hour. It's orbiting at ninety miles a [D7]second, so it's reckoned, The [D]sun that is the source of all our [G]power. The sun and you and [D]me and [C]all that we can [G]see, Are [Am]travelling half a million miles a [C]day, In an outer spiral arm, at twenty [G]thousand miles an [Em]hour, Of the [D]galaxy we call the Milky [G]Way. As I am told, a bit fact-heavy, but easier to remember than all those philosophers. |
22 Jul 12 - 09:53 PM (#3380136) Subject: RE: Shroedinger's Cat From: EBarnacle I was having a Philosophical Discussion about Quantum events at a party this evening and came up with an updated version of the Shroedinger question, vis.: If you place two horny teenagers who like each other a lot in a darkened room with comfortable furniture and tell them that no one will disturb them for a while, will the condom that each has in his/her pocket get used? Will they have sex without it? What are the odds that you will interrupt them in some sort of physical contact when you open the door and turn on the light? |
22 Jul 12 - 11:13 PM (#3380166) Subject: RE: Shroedinger's Cat From: GUEST,leeneia I have never understood the parable of Schroedinger's cat. I guess just a Newtonian girl at heart. Maybe that's why I prefer traditional music, too. Wikipedia has this to say: "He (Schroedinger) proposed a scenario with a cat in a sealed box, wherein the cat's life or death depended on the state of a subatomic particle... The thought experiment illustrates the counterintuitiveness of quantum mechanics..." I must be real intuitive, because quantum mechanics makes no sense to me whatever. Wikipedia also says: "Einstein pointed out that the state of an unstable keg of gunpowder will, after a while, contain a superposition of both exploded and unexploded states." All I've got to say is that here in Missouri, a powder keg is gonna either be exploded or not. Furthermore, I'm glad Einstein never had a job in public safety. |

23 Jul 12 - 11:46 AM (#3380423) Subject: RE: Shroedinger's Cat From: EBarnacle But is it dead or alive before you open the sealed box? This level of quantum physics is more philosophical than physical. It is analogous to the "If a tree falls in the forest and no one hears it, does it make a sound?" question. The question becomes "At what level does perception create the event?" |
23 Jul 12 - 06:03 PM (#3380576) Subject: RE: Shroedinger's Cat From: Gurney If there was a cat in a box in a forest and a tree fell on it but there was no one there, (apart from the cat!) would anyone hear it complain?
