isn't it just fascinating? I'm brushing up on the subject again after neglecting it for some two years. Eh! Probability waves! Electrons becoming particles when observed! Crazy! |
||||||||
|
|
|||||||||
| |||||||||
|
|
Yes, never mind philosophy, you want to fry your brain, read up on that stuff :) |
||||||||
|

quantum physics are like hats and flying geese - they go above my head |
||||||||
|
|
|||||||||
| |||||||||
|
|
quantum physics IS philosophy! :D |
||||||||
|
|
|||||||||

Quantum physics is weird. Particles being waves, and the other way around. Virtual particles, particles that only exist for microseconds and all that. It's fascinating, but it's also difficult to understand. |
||||||||
|
|

it also explains a hell of a lot of stuff. its amazing how many 'fundamental' particles there are. it can all be easily simplified so that all the particles in the known universe can be fermions, which exchange bosons of 4 types, depending upon the force acting, ie either strong nuclear force, weak nuclear force, coulomb electrostatic force or gravity....interesting stuff indeed. |
||||||||
|
|
|||||||||
| |||||||||
|
|
and we all have wave funtions corresponding to our partically percieved bodies :) |
||||||||
|

eh? all the panties in the known universe can be famous,which exchange bussoms of 4 types? |

and particles that go so fast, that their time slows down, so altho they only live a microsecond, they travel much further than expected ! :D and the possibility of tachyons, moving faster than the speed of light, and backwards in time! They use more energy DEcelerating than ACcelerating! :D |

Complete agree! I love it! I have studied pure mathematics and now i'm preparing my PHD-thesis on applied matematics with applications for quatum physics |

I'm an amateur in quantum physics, but "A Brief History of Time" by Stephen Hawkings completely blew my mind. |
||||||||
|
|

|
|
damn i wish I was a good mathematician! :| catharsis --- read the books of John Gribbin - they are very good - especially for the "amateur quantum physicist" :) |
||||||||

love it |

i use to have an obsesed friend who taught me all about it, well some of it. |
||||||||

|
|
You must be a good mathematician to explore quatum physics |
||||||||
|
|

i tried exploring quantum physics the non-mathematical conceptual way... didn't get too deep. |

haha that was my favourite show when I was a teenager! :D |

"hyperspace" by Michio Kaku is a good book describing how there are more than 4 dimensions in easy(ish) to understand english fo rthe layperson. |

quantum mechanically... we only exist because we are here to percieve our existence in the first place. .... is so simple its fucking amazing *disappears with a flash of light |

yeah, isn't that just ODD? "who is watching the watcher?" |

i dunno. coastguard? |

Aye, the John Gribbin books are very good. And it it's interesting how everytime they think they've found the elementary particles they eventually discover that they're made up of even smaller ones themselves. I wonder if that trend will ever end, and if it did, how could we be confident that we'd reached the end? And as far as the Copenhagen Interpretation (the one that says everything is a wave function that is collapsed by a conscious observer), that has very deep philosophical implications, i.e. it may lead us to a definition of what a conscious observer is. However, that's only one model or possibility for how things are really working.. I need to read up on string theory, I've fallen behind the times a little :P |

I saw Steven Hawking trundle past the shop I worked at when I lived in Cambridge. With 2 burly nurses. I was gonna shout "Alright Steve! What's it all about then eh?" but I didn't. |

Hi Marlow, try also to check the theory of relativity by Einstein, it is weird too! The mathematics is very simple but it blow up your mind! After that check also the theory which is a mix relativity and quantum phisics. Strange, this two theories contradict each other but it works. |

What was it like living with two burly nurses? |

I'm amused at the fact that electrons shoot back energy from the future to interact and interfere with their past selves. Ain't that just WEIRD?? |
||||||||
|
|
|||||||||
| |||||||||
|
|
...and we are electrons, right? what is this i remember hearing about electrons or maybe particles in general being able to "borrow" energy from "nowhere"... and there were specific probabilities invovled (of course); the greater the amount of energy the less probable it is that an electron would "randomly" achieve this sourceless energy. |

when i say that science and spirituality will fuse in the future, i suspect that some think (those that do not skip my posts) that i mean we will take communion from test tubes, or am promoting some sort of science fiction metaphysic like scientology. but i think that science, in conjunction with spiritual inquiry, will enable the discovery of how and why we exist, and aid in the application of this knowledge toward the tranformation of our collective reality. this will involve the perhaps uncomfortable abandonment of cherished assumptions, both scientific and spiritual. we can already see quite clearly our material assumptions about reality being dissolved. truly, when we are ready, a new world awaits us. The opposite of a correct statement is a false statement. But the opposite of a profound truth may well be another profound truth. -Niels Bohr, physicist (1885-1962) |

Yeah quantum physics is the shit! And Quantum is such a cool word. Wave function, photon, muon... physics has much better jargon than chemistry (boron just sounds boring, and it is) and even biology (although epithelial cells and purkinje fibres sound cool, they don't make you sound as clever). |

my physics teacher is just now beginning the quantum unit. |

muhaha you said quantum unit muhaha |

My roommate is a physics major, and he is taking quantum physics this semester. he talks about it a lot, and I realy don't get it or care. it's way over my head. I'm a communications major, for fuck's sake. He makes me feel really dumb :/ |
||||||||
|
|
|||||||||
| |||||||||
|
|
I'm going to be a physics major. Soon as I get out of this hell-hole they call "Pleasant Hill High School". Pwah. |
||||||||
|
|
|||||||||
| |||||||||
|
|
no worries. your talents in the field of communication far exceed his. ;) |
||||||||
|
|
|||||||||
| |||||||||
|
|
So clever! Arrg! |
||||||||
|
|
|||||||||
| |||||||||
|
|
i am also eager to get out of high school. only about 20 days left for me. =) |
||||||||

yeah, something like 22 here. |

marlowe, the effect you mentioned (self-interactions of electrons) is a problem of our mathematical description and no feature of nature, all amplitudes including self-interaction are devergent. it's solved with the renormalization precedure (for quantum electro dynamics in this case). The deeper reason for such problems is that there is a symmetry hidden in nature we haven't found yet and hence can't deal with properly. If for example supersymmetry is introduced to some qft's there is no need for renormalization (to get rid of the divergent self-energy contributions), everything is finite. |

Well, I was planning on going to a movie tomorrow night, but I think now I will stay home all weekend and read about the wonderful world of quantum physics... just sounds so darn interesting!! |
||||||||
|
|
|||||||||
| |||||||||
|
|
hey man, you got any sugested reading on the subject? |
||||||||
|
|
|||||||||
| |||||||||
|
|
yeah, but isn't renormalization an unsatisfactory explaination, a trick, that's been put forth to try and get rid of the infinities? The good thing about quantum physics is there's no "true reality" models that describe everything - you can get wildly different theories that produce the same results; maybe this implies future refinement and theory-fusion? nanotech - some recommended reading: John Gribbin, Schrödinger's Kittens Richard Feynman, QED (Quantum Electrodynamics) Hans Von Baeyer, Taming The Atom J.
