Joking aside i did this last year in school. It is stupidly confusing.
Rofl, no comment...
Wait, that was a comment!!!!!!
Meh, in for a penny, in for a pound...
Douche bag, when calling "ppl" uneducated, check grammar and don`t use abbreviations like "ppl..." Seriously! Ppl these days....
Lol, just kidding
With the "Ppl these days...." comment that is, not the rest of the comment...
"Consciousness . . . is the phenomenon whereby the universe`s very existence is made known."
I mean, I`m bored, but not that bored that I`m gonna watch an old fart explain some physics phenomenon...
... Sorry. This is nuts.
Oh, no less a figure than Richard Feynman said, "the result of the double slit experiment is the CENTRAL MYSTERY of quantum theory". He then corrected himself, saying that in fact it is "the only mystery. If you understood it, you would understand quantum physics, but nobody understands quantum physics"
So, though the explanation of this experiment is technically acurate, don`t go thinking you can alter reality with nothing more than willpower; such logic is likely to land you in a detox facility or in a room with padded walls.
By the way this is terribly Copenhagen interpretation biased!!! As a MWI proponent, I`m offended.
Cool vid btw.
Look at it this way. If two electrons were fired, side by side, one at the left slit and one at the right, we would assume that each would pass thru its respective slit, and interfere with each other on the far side, causing a wave pattern on the wall. But if a detector is placed in the right slit, the electron that passes thru that slit is slowed down minutely by having to interact with the detector. This throws off its timing with the other electron, so they no longer interfere with each other. This process works the same with just one electron, as shown in the video. The detector that is used interferes with the experiment, and causes the particle pattern to appear instead.
To professor: Nice outfit.
Go google "Heisenberg uncertainty principle" or "quantum mechanics" or "wave duality" or "planck`s constant" -- there is a ton of very interesting and comprehensible material out there (be warned that the math involved is highly complex).
A last note to the subjects of my first remark -- I thought exactly the same way as you did, then I decided to major in physics in college...
Wow. Thats drating cool.
That`s actually one thing that I`ve always gone crazy over. How do I know that the refrigerator (or anything else) doesn`t act differently when no one is watching it?
The observer in this scenario was some sort of electrical device so you can guess that those electrons where affected by the device the same was a magnet would be affected by another magnet.
Basically, light is magical.
But hey, I guess I learned something.
"So it has NOTHING to do with the fact that someone is `watching` the experiment. Electrons don`t change their minds of what to do based on whether someones watching or not."No, that really IS a phenomenon that happens. Just because they weren`t watching it with their eyes doesn`t mean they weren`t perceiving what was happening.
First off, when they talk about `observing` the electron, they don`t mean putting a camera and `watching` it, as the video suggest. What they do is put tiny detectors in each of the slits which monitor whether or not an electron passes thru. So it has NOTHING to do with the fact that someone is `watching` the experiment. Electrons don`t change their minds of what to do based on whether someones watching or not. So quit talking about trees in forests and ur reflection in the mirror (it doesn`t disappear don`t worry). The world does not change just because you watch it or not.
Now about electrons. True, they do have negligible mass, but they still travel at near the speed of light, meaning that an electron CAN be at many places at once. When you turn a light on, it immediately fills the room, and an electron can almost do the same...
::is a perv::"man, i was thinking that the whole time.
"and its ppl like you that makes most humans uneducated"uh, you just said "ppl". i wouldn`t call someone uneducated, especially just because they believe something different than you.
EVERYBODY GO RENT/BUY/WATCH WHAT THE BLEEP DO WE KNOW. good movie. especially if you`re into quantum mechanics.
I don`t believe it for a second...
I love how he was all "now, with two slits it should act like particles and make 2 markey things... WHAT?!"... Wacth it again and you`ll see what im talking about...
They`re now building a 27km circumference accelerator which will use 1/10 of switzerland`s power at full speed.
Hopefully, they will uncover the "Higgs Boson", aka the "God PArticle", aka the thing which makes gravity!! Hoverboards could become a reality guys!
Either way, Wiki it, its well interesting.
Good clip--VERY clearly explained. I wish we had watched THIS show in science class instead.
An easy way to do a double slit experiment at home is to bounce a laser pointer off of a glass (it has to be glass) mirror at between a 45` to 60` angle.
If you do it right, you should see an interference pattern on the surface the laser reflects onto.
This is because the surface of the mirror and the back of the mirror will reflect at slightly different angles and emulate two slits that the same laser beam is going through.
You can also try to cut two slits in a piece of cardboard but they mush be no further apart than the width of the laser beam and is a pain.
We never did the electron version of the experiment, I guess because this way they manage to teach us about the photo-electric effect and (wave) superposition at the same time. then use wave superposition to explain quantum superposition.
They don`t state the method in which the particles are observed, but I would assume that the observation method is tainting the results by distorting the wave (electromagnetic device?) and making the particles flow straight again.
I wonder why they always have to use such childish presentations. Then again it must be like trying to explain IT to management: fall back into kindegarten speech ;)
You gotta be open to everything even if it seems weird to you, it just might be right.
^for the above it would help if you were willing to accept that everything in the world is connected "and one" as well as the ability to manipulate the world/energy you are connected to.
2) As far as God goes (assume you believe) who`s to say he didn`t "think" us into existence then allow us infinite electrons to create our own environment and settings as per His allowance to us of ultimate free will. (If you don`t believe, don`t argue, it`s a theory not a religious rant). 2b) we have advanced because we have grown in our ability to create and manipulate the electrons.
Here`s one1) Electrons must `materialize` because we (eyes and brains) cannot comprehend something being in more than one form.1b) This however, leads to another conclusion that can be drawn (if you believe in this kind of stuff) That we actually control our environment with our consciousness. So things exist, because you believe they do, and not just that you do, but the popular opinion agrees that you actually are seeing what you`re seeing. Perhaps you`ve seen something differently than another person and then you`ve disagreed, that could possibly be your mind constructing something to your own personal view. Which happens often when someone (2 people) observes something completely objective.1c) Also have your eyes ever "played tricks on you" who`s to say that in your peripheral or even frontal vision your mind didn`t construct the electrons to match something your sub
And at the movie, it`s interesting, but weird. how did they `observe` something with the speed of light anyway? Would be fun they actually tried this in a CAT-scanner and go like `OMG now it`s making round patterns! we do not understand! D:` ... uh well, assuming electrons are attracted to magnets..
Oh my gosh, calm the f*ck down, kid... anywho, I`ve seen a video of the double slit experiment somewhere else, but they never talked about waht happens when the particle is being observed... way cool!
::is a perv::
Kinda makes you wonder just how much we don`t understand, doesn`t it?
Really makes one think... when someone tells you not to look, would the course of history have remained the same if you actually looked/not looked?
Maybe we just perceive it as two bands when we`re observing it because we can`t fathom existing in 2 places and existing and not existing at the same moment...
But interesting nevertheless
opens a hallway with a million unopened doors
but how does an obsever effect the pattern?
