Quantum Physics Explained - Basics - General

Hey, I don't know if you're interested in this stuff, I was way into quantum physics and stuff for a while when I was 11, but now I kinda laid it off a bit. I was wondering if anyone else shared the same interests... If you do great! If you dont, take a look at the video below, its enough to get you questioning how weird the universe is. the purpose of this thread is basically to expand the understanding of the weird universe we live in. Oh and dont worry, its [I][U]really[/U][/I] [B][I][U]really[/U][/I][/B] easy to understand, all you need to know is what an Atom and a electron is, then you are set. [B]Video[/B] 100% Intrigue guaranteed Quantum Physics Introductory - Double Slit Experiment [media]http://www.youtube.com/watch?v=DfPeprQ7oGc[/media] EDIT: By the way, I think you should care. And yes, it is funny. Also I was into the basics at that tender age, of course I would need intense mathematical training to understand the whole probabilities of it. Fine I was 12, happy? And thank you very much for clarifying that johnnymo1 :D [B]PEOPLE CURIOUS ON HOW TO DETECT/SENSOR ELECTRONS[/B] [url]http://en.wikipedia.org/wiki/Double-slit_experiment[/url]

Hey Eudoxi- Oh wait.

What the bleep do we know is a horrible movie.

The funny thing is you think we care. Why is the guy talking an animated pedophile.

If people want to learn about quantum physics, I don't think facepunch should be the outlet anymore. I've seen more than a few threads lately about abstract scientific concepts. It just isn't original.

[QUOTE=GoodAyres;22452152]I was way into quantum physics and stuff for a while when I was 11[/QUOTE] You are a LIAR!

I've come to learn that whenever someone presents complicated physics in a simple and cartoony way, they're almost always lying. The main problem with the video is that, yes, while viewing the electron supposedly makes it act differently, have any of you ever asked what our method of observation are for things on that scale? Do you think we just get a really big magnifying glass?

Wait, is that the voice of Breen?

They have a sensor... But then again, that's the way I would explain it.

In short, Quantum theory has been buttfucked by a bunch of smacktard Arizona liberal new age hipster fucks who don't know their own asses from a worm hole.

You're doing nothing but taking the word of a cartoony propaganda piece as utter fact.

[QUOTE=adamater;22452182]The funny thing is you think we care. [/QUOTE] I am interested.

I want to know what the actual method of observing a particle is.

[QUOTE=Eudoxia;22452562]I want to know what the actual method of observing a particle is.[/QUOTE] It's a giant eyeball, silly. Didn't you watch the video?

It seems I am subject to flaming here. I found it very interesting. And by the way Mr. Scorpio, The double Slit Experiment hasn't only been mentioned in What the bleep do we know, it was first theorized in the [B]early 1900's[/B]. What are you tying to accomplish, completely wipeout any form of quantum physics from the face of the world? I assure you won't manage that, instead you come to a thread and decide to ruin it for others that are interested? And just to prove my point that it is true, [url]http://en.wikipedia.org/wiki/Double-slit_experiment[/url] there you go. Happy? I just proved you wrong besides the fact I wasn't making propaganda for the movie, which is a steaming hot pile of shit, I was making propaganda for the experiment itself. Thank you. This is Good Ayres signing off. BTW method of observing the particle is above. :) I'm sorry!!! If you are really worried about mixing it up with space age stuff, disregard the last part when the guy says "because it knew it was being watched"

No, GoodAyres, he's just complaining about the new age pretentious hipster retards who believe in Quantum Mysticism and the power of mind over matter.

Scientists use electron microscopes, which fire electrons at a surface. Different atoms interact with the electrons in different ways, so by analyzing the different signals that are reflected, scientists can determine what an atom is.

Thank you for explaining.

Keep calm and carry on, jeez.

[quote]Hey, I don't know if you're interested in this stuff, I was way into quantum physics and stuff for a while when I was 11[/quote] no you weren't..

Double slit? :smug:

[b]What!? An interference pattern!?[/b]

While this is a good explanation of the double-slit experiment, What The Bleep Do We Know? is a scientific masterpiece on par with Insane Clown Posse's Miracles.

I might be coming off as sarcastic but I have a legitimate curiosity for this kind of thing. edit: clocks please.

You can't sense electrons by firing more electrons at them.

[url]http://hyperphysics.phy-astr.gsu.edu/hbase/quantum/davger2.html[/url] This kind of explains what the animated wackjob was talking about. Matter behaves like a wave, which is what this experiment proves, and gives the equation of that wave.

[QUOTE=greendevil;22453524]You can't sense electrons by firing more electrons at them.[/QUOTE] Actually, that's one way that scientists discover new subatomic particles. By firing electrons (might be something different, not sure) at an atom of known mass, other subatomic particles are ejected from the atom, and using simple conservation of momentum principles, scientists discover new particles (my former physics teacher speculated that this is how they discovered the mass of the electron).
