Dr. Quantum Explains Double Slit Experiment

[SLemonspunk]

I'm sort of new to this whole quantum stuff, but doesn't it have to do with uncertainty? Correct me if I'm wrong because I don't want to go around acting like I know what I'm talking about if I don't.

Holy fuck

It's Jimmy Neutron in the future!

holy fucking shit my mind is blow

HELLO EVERYONE, I HAVE CREATED A SCIENCE APPLICATION USING THE DOUBLE SLIT EXPERIMENT. I WILL ENCODE BINARY DATA USING PHOTONS WITH EITHER A 0 or 1 AND WILL BE CAPTURING THE WAVE INTERFERENCE PATTERN PHOTONS USING 5 INFRARED PHOTOTRANSITORS TO SEE IF THE DATA IS THE SAME OR DIFFERENT THUS POSSIBLY PROVING THE "MULTI-VERSE" THEORY.

Feynman's book: QED (strange theory of light and matter) treats this quite well. It is a book for the layperson and I would recommend it. There are a dozen other gems in there.

Feynman: "If anyone ever says they understand Quantum Dynamics - they probably DON'T."

[CanaryKeeper]

This sounds like something out of Doctor Who...@_@

2:22 - A wild interference pattern appears!

[crazdaveed]

Quite sure as physicists they tried any and every type of monitoring device because this baffled even Albert Einstein and every other scientist who has lived... but no it shouldn't interfere with the wave pattern anyways. Quantum mechanics states that all matter at a quantum level can exist everywhere at once until "observed" and this supports just that. Weird :)

[MusicIhave]

where's the rest of this video?

[dogonname]

um... so my question is what type of measurement tool are they using, because if that is emitting electrons just because of the type of tool it is. As amazing as this is, could that tool be the differentiating factor that made them change?

[soulkillerk36]

@dogonname

yes you are right, this video doesn't explain what "observing" is, and they make it seem like a scientist goes up and looks at the slits, but in actuality it comes down to the fact that every type of measuring device has to bounce of some sort of energy on what its measuring, but even when they measure with the smallest possible unit, photon, it still has a effect on the electron by collapsing the wave function. By why this is, and how to measure it is still a mystery

Highdeas sent me here

[DirtyBaseKids]

@StratoBlaster420 Same here man haha

[MrCODforME]

@StratoBlaster420 yip :D

[CRFisFTW]

i think the camera disrupted the wave pattern somehow, im no scientistjust a guess but could this be true?

[3Dthermalunderpants]

Well, the reason that stuff in quantum physics acts differently when it is being observed is because the measuring machines, which are the observers, are shooting photons at the particles in order to measure them, not because the light is conscious. The act of observing in quantum mechanics is not some passive act, rather it is involved with the experiment and will influence the experiments results.

@3Dthermalunderpants sooooo lets get the fock out from big brother society and leave life in its beauty FREEE and NORMAL IN ITS LAWS,.. LEAVE LIFE ALONE ATEISTS,..SCIENTISTS,..LEAVE LIFE LIVE FREE

[dootmc]

Quite alot of these comments seem to be from people who already know more than the video is teaching.. So I just want to speak for anyone who's learning this for the first time in saying, "holy shit, what the fuck!?!?!?!"

[longjap]

Wasn't the elektron smart enough to know it was still being observed afterwards? Elektrons are dumb.

Our space is abstract, the minute your conscienceness tells you it's oughta be, its oughta be. Right now i'm flying with my lap-top over Rio. See ya in the 3D world.

[vi67]

To observe electrons would interfere we have no instrumentation to do the detecting that would not interfere.

[1DR31N]

I wonder what happens with one observer in each slit

[DoggyMan2222]

Lol he looks like my physic teacher.

[RobAlone]

Not that it matters, but they don't mention that the waveform collapses even if you 'turn on' the detector after the electron has already been 'fired'. The point is still made with this video.

[Chrisboe4ever]

Perhaps the data used during this animation was out-of-date.

[tritisan]

This is a fantastic visualization of a very tricky subject. Things get even weirder with a new variation on this experiment that seems to break the law of causality: Google "Scientific American Do-It-Yourself Quantum Eraser".

[ltzippy2]

Wow! I never understood the quote "collapsing the wave form" before. It's good to learn.

[aslipperyslope]

Just subbed. think I'll stay awhile. Compelling & wonderfully presented.
