Double slit experiment (quantum mechanics)

[austpom333]

0:20 looks like some sort of eye forming ( third major line across 3/4 up )

[austpom333]

That would be experiment unobserved

[sclogse1]

Probably flourine atoms.

[nickharvey7]

Neat video!

This is an invitation to see an artist theory on the physics of light and time!

This theory is based on two postulates

1. Is that the quantum wave particle function Ψ represents the forward passage of time ∆E ∆t ≥ h/2π itself

2. Is that Heisenberg’s Uncertainty Principle ∆×∆p×≥h/4π that is formed by the w- function is the same uncertainty we have with any future event that we can interact with turning the possible into the actual!

WHAT? AN INTERFERENCE PATTERN?

[edictOFsparx]

so electrons seem to react to being observed????

you know what this mean???

electron porn

[Whelouski]

If the electrons act like particles when observed, it appears they don't mind having their data recorded and observed afterwards. So visual observation makes them behave as a particle but however this video was made doesn't make them shy about doing the wave thing??? So electrons aren't objects but something else then???

you silly particle, why you acting like a wave function?

[Thireus]

Hello, thanks for this video, but where is the similar experiment with an observer that proves the wavefunction collapse ?

[BendableCard]

I'm making short comedy skit videos and am partial towards physics and math humor. I'm going around to popular physics/math videos promoting to try to find a crowd that can understand the jokes. If you have some time please check out my channel and the video subatomic particle party. Thanks for your time.

[Hobbzie22]

@6RE66Y13OY  thats Bohr right?

[6RE66Y13OY]

how do you know that quantum events when observed aren't just optical illusions?

[Nvidiaguides]

People who say "This is wrong" are, in my opinion, ignorant, insecure human beings that cannot admit they are wrong and are afraid of what they cannot understand.

[lewis12121]

does anyone believe this mumbo jumbo? Show me the real experiment, the one that they did originally, not an animated video. Sure it helps of you're stupid, but once you've come to terms with the theory the only way to be sure they're not spinning you a line to justify their billions of dollars of research money is to the thing for real. How strange that there are no videos available!?!

[GuitarMannnnnn]

@lewis12121

Sorry to burst your bubble, but the experiment works. You can do it with pencil leds and a laser pointer. Just in case you want a video of "the thing for real". Here

watch?v=UANVMIajqlA&feature=re­lated

[Soulless99]

@lewis12121

whenever scientists publish an experiment, result, analysis or theory, it is subject to trials by just about every other scientist around the world, trying it out in every way possible. Anything that is faked, dishonest or the likes will be quickly revealed and the culprit blacklisted.

Besides, there are several videos available where this experiment is done in real life, if you just open your eyes and stop being so narrowminded.

[jaysuscrust]

Is it true that observing the outcome changes to results of the experiment like it does according to Dr Quantum? :)

[StrongPrawn]

@jaysuscrust No

The apparent deviation from observation is because the observation interferes with the experiment

[wahrschein7]

Es scheint mir wahrscheinlich, dass dieses Video ein echter Muster des Doppelspalt-Experiments demonstriert. Es verwirft grundsätzlich die Welle-Teilchen Dualität. Das nur teilchen-artiges Verhalten von photonen, Electronen und Atome kan bei der realen und neuen Wellenfunktion bestätigt werden. Diese Funktion wurde zum ersten Mal in dem Artikel “Wave Function, Developed Gaussian Distribution” eingeführt, veröffentlicht in toequest.com, September 2008.

[c3r13e12u5]

you should do this test on the space, not in the earth where many other particles will affect the result such as air pressure between the slit and the wall.

it could be that the particle actually moving in a circular motion like a wave in 3d and when it reaches the slit the air pressure cause the circular motion to narrow and after the photon pass the slit it widen again caused by the 2 slit air pressure changes. which caused the pattern. while in one slit there are no air pressure changes. O.o)

[MaweyPamtseosiyu]

@c3r13e12u5 yea, that.

[martyfmelb]

@c3r13e12u5 I also agree. I think the only way to get a 'clean enough' environment to check this is to run a pair of simulations: one WITH air, light, heat, gravity, ambient magnetism etc (i.e. earth-like) and another without any of those (perfect vacuum, no heat, zero-gravity etc). If you get wave patterns in the former but not the latter then it's Quod Erat Demonstrandum Matuis Futuor :) and quantum mechanics can pretty much be thrown in the bin.

[TheEvilCommenter]

You must allow nature to dictate what is and is not sensible. As Richard Feynman once wrote, "Quantum mechanics describes nature as absurd from the point of view of common sense. And it fully agrees with experiment. So I hope you can accept nature as She is---absurd."

[starsoffyre]

It's not possible to explain it anyway. Since our minds have adapted to the macro world (which is all we need for survival) over billions of years, trying to understand something in a different realm would definitely be out of human logic. Of course, the best we can do is to make observations.

[wahrschein7]

It seems to me likely that this video demonstrates a real pattern of double-slit experiment. Of course, it needs mathematical interpretation. Double-slit experiment (The heart of quantum mechanics) has been explained through the new wave function of probability in the following webpage:

[TheQRabbit]

This is a beautiful experiment. Thanks for showing it. Where was it done?

[joeglimmix]

@TheQRabbit in the ghettos of east st. louis

[jeffkosmo]

Does anybody know...

If in fact the interference pattern is being caused by atoms that are somehow able to interfere with themselves, then it should be the case that roughly 35% of the atoms fired at the slits - don't appear on the screen. However, I've never heard this to be the case. It's implied that for EVERY atom fired, an atom appears somewhere on the screen.

In the meantime, please see my video, "DeMystifying the Schizophrenic Photon" for a different spin on the puzzle.

[formula406mpfi]

Tim Rotter has proven the double slit experiment a total sham. The heart of this truth comes from a simple paradox. What is the difference betewen placing an observer to view the electron's path vs the lack of an observer? Nothing because in both cases, there is a measurement made. The act of measuring controls the action of matter in free space/time. There is ALWAYS a final measurement made in the double slit experience. Therefor it is not valid. Not in the sense we are lead to understand.

[kufr72]

Reference please?

[michalchik]

Which is part why it is so weird. He may have proven it logically but he is simply wrong. Nature does not have to obey our sense of what is possible. When you measure and, if you measure and if you know the results of the measurement all make a difference in how the universe works,

[C0LL1N]

isnt the most important part of the experiment trying to measure which slit the electrons go though which causes them to form a patter of two bands?

[nickharvey7]

In my video Quantum Mechanics an artist view Time has symmetry and geometry that can explain the two slit experiment of Quantum Physics.

[jackofwack]

I went to the doctors. I said "I'm having a problem comprehending reality"

He replied "Really?"

[laughingmandude]

That's funny and I know how you feel. The idea that we are a product of billions of years of a coalescing universe comprised entirely of small amounts of matter (fundamentally energy) just kinda takes some of the comfort from a living, autonomous being. It's actually pretty terrifying to think that what we think is consciousness is really just matter arranged from necessity over time; it seems like an illusion and is very demotivating especially when, given this, death is most probably nothing.

[k7leetha]

@laughingmandude

Or the beginning of ...everything...

Being released from a singularity (life) into the collective quantum reality (death) could be the grandest form and consciousness. Many cultures throughout history celebrate death (wakes) as new life for their loved one, a life free from physical restraints.

[laughingmandude]

@k7leetha The grandest form is formlessness.

[laughingmandude]

@k7leetha Haha, but it is maybe only theoretically possible.

[mrbumpman]

in reality nothing is really there

[MafferDragonhandEyed]

i just do not understand. It like trying to understand how matter created itself out of nothingness or, somehow has always existed. It just does not make sense...AHhthis experiment. If nothing was flawed and this is all true then WTF? HOW> AHh

[seek223]

So... let me get this straight... electrons etc. still behave like a wave when you observe them clashing onto the screen... but if you observe them going through the slits, they'll behave like "normal" particles of matter?

That's rather scary XD.

[tlast2012dude]

lol yeah, this is freaking my mind, i just discovered a few minutes ago, i'm searching the way to do an experiment by myself.

[seek223]

wondering if it works if you just look at it... and why this isn't the case with i.e. light.

Maybe you could use an old tv... don't they have electron "guns" in there?

Why doesn't the picture get distorted when I look at it, XD? ^^

[daevltimi]

This is the case with light, photons act in a similar manner on a small scale.

Obviously we don't see light behaving like this, because it is being observed.

[HomerJ666]

@seek223 what do you mean by "looking" at it? looking at it means shooting photons against it, which then hit our eyes. as the photons hit the other phoeons/electrons the wave function collapses. if you observe them AFTER they hit on the screen / after the slit, it doesn't matter if they still act in their wave function.

[sarahmhmyeah]

Isn't it? It's a crazy world.

[swakleete]

The observation process causes the electron to collapse into a single state of probability.

[rooflee]

@swakleete How does the electron know it is being observed?

[Tanarune]

it doesnt, its becouse of what heisenberg says. As long as we don't observe it, it can be on different places, it's by observing it that we are forcing it to be on a specific place

[quidproquo2004]

@rooflee When the term "observation" is used in the context of quantum mechanics, it does not generally have the same meaning as it does in colloquial speech. There is no support for the notion that it must be a conscious being measuring the state of a particle to cause its wavefunction to "collapse".

[daevltimi]

They don't neccessarily behave like a wave, but they give the same results a wave gives.

We can't know how they behave because as soon as they are observed they begin to stop doing things that are seemingly impossible, and just behave like larger matter.

[sasasay2001]

what would happen if you place a wall between the slits (behind the slits) so that electron wave does not intefere with wave from next slit?

what would happen if you force electron onto one slit only (by making gap btw slits wider, leaving the wall between the slits behind the slits)?

the results of the above can through some light if observer causes the electron to behave wierd or any obstruction would change electron behavior. I think electron would behave as matter for above 2 experiment

[sasasay2001]

"I think" is different from what might happen .. but would only know if someone tests these .. which unfortunately i cannot do :(

[Bowman1084]

Are these photons attracting each other? You can see not all photon particles land together in the wave pattern. They could be flying through the slits and be attracting each other and moving left or right to to where they are attracted. Then the measuring device used could be building a stronger attraction keeping them in a more 2 slit line on the backdrop. Just a guess. I am no quantum physicist Thats for sure.

[meusicalentall27]

lol..photons? no

[Bowman1084]

What is this measuring device? What frequencies is it running at? Does it create a magnetic field? Does it give off some kind of wave to make these photons act a certian way? What is the backdrop made from? Does the observing device charge these particals and and they are attracted to certian areas of the backdrop by magnetic fields? There are so many possiblities to why this happens.

[DogsinSpace1]

The measuring device does not affect the photons, it depends on weather you look at the data collected by the measuring device that has the affect, if you have the measuring apparartis active for the experiment but destroy the data before you look at the screen, there will be an interference patern on the screen.

[gyro5d]

@DogsinSpace1

There's a probability of wave or particle until a conscious being observes the data. Have Schrodingers cat or a chimp look at the data, see if the photon collapses into a single state of probability..

[Sonicku]

soooooo.... it dosent exist unless we see it? or is the observer not meant to see the truth?

[ChewieFlakes]

It is a wave of possibilities until we observe it, the wave function collapses

[aletorno]

You can see a REAL double slit experiment in my video called Double slit experiment. Thanks for the video.

[xGLAVONJAx]

why the fuk do you mix god with science....god is not what you think it is son! YOU are god , I'm god we are the creators.....once you accept that you'll live a better life ;-)

[sergiomarchelli]

hihi this is a great delusion too...

[RMProdux2008]

hell yeah

[Andylocksigma]

The entity making the conscious decision in light is...God. "God is light" I John 1:5.

What does God have to say on Quantum Chromo Dynamics and Quantum Electro Dynamics?

[Sonicku]

so what are u sayin that god dose not want the obserever to see the univerese? or the truth? so it changes tthe outcome so that the obserever can not understan the universe and understan God?

[tomelsmith]

An electron bouncing of the side of the slit does not create a wave-like pattern, why would it?

[Rybach]

any one who sais this is nonsense must remember that the finest minds in the world have been working on this for years,And You are?

[exponentialnegative1]

What makes you think that the "finest minds in the world" aren't just scientists accidentally influencing their experiments to get the results they want? That would support this quasi-scientific understanding of how the individual relates to the experiment.

Essentially, I think the issue is that science doesn't include the observer. Religion, the opposite, worries all about the observer without any science.

[AngeCord]

I am pretty sure, because there is always some techology guy one step behind the physicist trying to apply the findings on some new invention. If the theory is wrong, the gadget won't work.

[andrew1381]

Stoned again!

[xlcollins]

@Rybach a physics student and just because it works doesnt mean its right, actually schrodinger himself invented his famous paradox( which people always misundertsand...) to show that the something in the fundaments of quantuum theory is wrong

And, you are?

[Zico31]

I came across this experiment/theory just yesterday and obviously have not seen an actual live recording of both possible results. How did the scientists discount or remove the possiblity that the electron may be deflected off either the side of the slit causing the appearance of a wavelike pattern?

[vi67]

This video is misleading, as:

"The observers are not robotic blinking eyes but other particles bouncing of the test particles. Yes thats right,they are physically altered by the method of observation."

[tubemaster6]

ok but then you have to explain how test particles in the area of the experiment could make electrons behave like matter again and not waves, although the video should've mentioned that fact

[dmtforme]

let me get this right.... The electron goes both in the slit and not at the same time, if you were to make a device that when the electron was fired it killed a cat when it went through the slit and nothing happens when it doesnt. does that mean the cat is both dead and alive at the same time when the electron is fired?

[Tchebu]

The electron (or any other particle) goes through both slits (there are two) and then lands at one precise place on the screen. If you were to put a measuring device in front of the slits to see which one the electron "actually" passed through, the interference pattern that you see in the video will disappear.

[jasontimmer]

Have you heard of the Schrodinger's cat thought experiment? Look it up. Schrodinger says yes, the cat is both dead and alive, or according to the multiple worlds theory, the cat splits into two different universes, one in which it is dead and another in which it is alive.

[dmtforme]

yes i have heard of the cat experiment, but forgot the conclusion, thanks for clearing this one up.

[phuturexy]

schrodinger was a silly old fool, how can cat split into two universe lol

is still same cat in box, alive or dead

[vstankovski]

I believe this is nonsense. The electron passes through one of the slits. That's it. There must be something else, which is disturbed by the photons, which makes the electron to fly like a bullet. :)

[jasontimmer]

In a more complex experiment I saw performed elsewhere, they did the experiment, went away for a day, and came back. at this point, they decided whether or not to look at the information gathered by the measuring device at the slits. If they decided to look at the info, it would turn out two slits appeared. If they decided to just discard the info, an interference pattern appeared. A decision they made today affected an occurence yesterday. We are finding more and more that this is not nonsense.

[Mankano1]

You're talking bullshit.

Read something about decoherence theory, schrödinger's cat and quantum theory in general before posting some random crap.

[Goldiney]

Sorry, you're wrong.

[vstankovski]

Who is wrong? Could you please explain? I am very curious about this experiment.

[RexNunc]
