Quantum

[aashbourne]

hey everyone,

i was wondering if anyone on here is fascinated by quantum physics, i have been watching some videos about it on the internet, and it is crazy stuff. i just want to hear your views on it.

ps, this is cool

Wait a minute, let me get my pocket protector and I'll be right with you.

[tippy]

ha ha, smarty pants.

Hey Alex, I watched the video and know next to nothing about qp but after watching my two comments are (1) in the video they showed the observer as a rather weighty mechanical object which of course has it's own matter as particles and waves to contend with and (2) what about all the matter within the experiment space to begin (with the anti-slits and the backdrop).

Oh that crazy wacky physics! Reminds me of the good ol' days when we just laughed and laughed our way through it in the 10th grade.

[Squaredancecalling Steve]

And Alex, at 16, most likely is in 10th or 11th grade.

[Jimmy Cantiello]

Action-Reaction Law - For every action there is an equal and opposite reaction.

Hey, Alex, why don't you get together with one of your female classmates and test out this theory.

[Squaredancecalling Steve]

James! Are you trying to get this fine young lad in trouble?!

[Jimmy Cantiello]

Who, me? Nah, just tryin' to teach him about quantum physics and the laws of nature.

[aashbourne]

hey everyone,

yes, i just graduated from grade 10, next year i will be taking physics, but one of my co-workers started me on qp, i just think it is really interesting.

but tippy, if they are doing this test with electrons, wouldnt it have to be in some form of vacuum or something so that there is no interference with other particles?

cheers,
alex

[tippy]

fair enough except for the observer obviously emitted some force on the experiment but maybe the robotic eye- that looked much like a 1950s hairdryer - in the cartoon was an exaggeration.

[aashbourne]

hahaha very true

The study of classical physics is very different from the study of quantum.

"Action-Reaction Law - For every action there is an equal and opposite reaction."

This is from the classical study of physics, not the study of quantum physics.

[Vince Kargatis]

Quantum is hard.

Reminds me of a friend of mine in his master's oral defense. A prof asked him to explain charge exchange, and he answered "something to do with quantum mechanics?". That busted us up. Except for that prof. Who failed him (i.e. gave him a terminal masters, unable to proceed to the PhD).

Now there ya go gettin' all serious on me. Sometimes you're no fun, Bo.

Just sayin.....haha.

If I understand correctly, quantum physics demonstrates that really, really tiny things act weird--and have funny names! Do we really need huge scientific research budgets to tell us that??

Yup.

[Gary Sisco]

Actually, what it seems to be telling us, based on evidence and well-grounded theory (so far), is that everything is made out of those really, really tiny things with strange names.

It's not so much of a leap if you remember that more traditional physics said the same thing about atoms, also mighty tiny things. Particles are tinier, that's all, and there'd be no atoms without them.

I like to read about these kinds of things, though I'm far from grounded in the science itself, and am usually some years behind the most current work. It bends the mind, pretty well, and is a good workout for the brain.

Actually, the subject is so rarefied, even mildly informed people (myself included) are probably decades behind the most current work.

[Gary Sisco]

True. The last book I read, a short while back, was published ten years ago or so. Still, fascinating stuff. I haven't time to keep up with it as it happens but like to tune in now and then to work out the brain.

[bobetterblues]

I just read a good book entitled "Entangled Minds" by Dean Radin. It's basically a study of psychic phenomena, like premonitions, mind reading, etc. But Radin comes from a quantum physics standpoint. In the quantum world matter becomes "entangled" for mysterious reasons, and moves from one plane to another, while still entangled..... Radin applies this and other quantum theories as well as more scientific research to prove that "psy" exisits. Cool book.

[clinthopson]

I was hoping for more string theory.

[Gary Sisco]

Thing that gets me about particles is that they can exist in different places at the same time.

[Tom Storer]

The last layman's physics book I read (ahem... the only layman's physics book I read) was "Dance of the Wu Li Masters" or something like that. It was extremely mind-bending for someone like me, whose hard-science quotient is near zero. As much fun as the bit about particles being in two places at once is the bit about particles going backward in time. Cool!

[Jimmy Cantiello]

I'm in the same boat as Tom except that if I read any book having to do with quantum physics I'm positive my head would explode.

[Gary Sisco]

It really does a number on the concepts of time and distance. They may well be irrelevant concepts outside our own minds.

The last book I read said there are an estimated 100 *million* black holes just in our own galaxy. There are nth-thousands of other galaxies out there, just the ones we're able to see from this planet.

[Jimmy Cantiello]

Oh Christ! My head is starting to hurt.

[bobetterblues]

A good book to start with is called "what the Bleep do we Know" and it was published after a movie was made with the same name. The movie sucks, so don't watch it, but the book is great.

It covers qauntum physics, brain study, emotions and their effect on the body, psychology, religion, etc and ties it all together. But it is all is layman's terms. It's a fun rabbit hole of a book.

[Gary Sisco]

Alex -- Thanks for telling us your age. This place can rock pretty hard sometimes, so hopefully we will remember before we flame.







Nah.
