double slit experiment [NOVA]

The double slit experiment explained by NOVA
Episode: Quantum Leap (The Fabric of the Cosmos)

[Wilvin]

This doesn't fully explain the double slit experiment. They're missing the even more mysterious part about what happens when the electron is being observed.

Warning: quantum mechanics can cause dain bramage, I mean, brain damage.

try to observe this shit then it'll act like a fucking bowling ball

[Deathend]

tl;dr Instead of figuring out why the double slit experiment works some dude said, and I quote, "Math, yo.", and came up with a formula to predict where things would end up and said that explains it.

So basically it acts like a wave, we pretend it is a wave, but we chalk it up as magical math instead of figuring out why it happens.

Whenever I am giving a lecture on quantum physics, I feel as if I am talking about Vedas. (Spiritual and scientific books of Hindus written down in 5000 BC and an oral tradition before that). I studied matter for 35 yrs only to find that it does not exist- exactly what Adishankara said (a Hindu sage -2000 BC) long back from the upanishads.

" All that you see does not exist"

This is THE BEST video on this on the Internet by fuckin far. Thank you!!

This forgot to mention the observation part. This is a horrible piece by NOVA and needs to go away like the Chevy vehicle. Oh, and in 2012, this was already known. Author should be let go as well. Really poorly researched segment on this.

[medaphysicsrepository]

Heres the part I don't get, at first I was under the impression that "measurement" was a technical problem (using an electron, photon whatever) the act of measurement would require something interacting with it and cause the probability wave to collapse (mathematically "impossible" by schrodingers equation but Idk shit about math ) into a fixed point (mechanism? who needs that in quantum mechanics) but wouldn't the act of firing an electron or photon or anything be a form of interaction? so the question is how do we define measurement ?

[oguzhan]

Yea this explanation explains nothing.

A photon is a wave. It travels as a wave, always! But its energy is absorved discretly following a probability distribution.

[al]

When an electron (energy, light, heat) travels through these 2 slits (keep in mind these slits are nano size) they give up a minute amount of heat to the slit walls causing its path to be altered. Many of these electrons don’t make it through the slit and are changed to heat on he slit walls.

Also, how is it that these “waves” only spread out horizontal? If light does travel as a wave and/or its all about probability, wouldn’t there be a distinct pattern directly behind the slits at the upper and lower part of the back wall? Light doesn’t only travel like a wave horizontally.

[daffertube]

Wait so how does the observer factor into this? Last thing I heard about this is that the electron will change its behavior based on whether or not it is being observed.

Can someone enlighten me? I feel like I'm not getting the whole story here.

[chloroform]

Seems like everytime there's an explanation, at first they use actual physical bowling balls or big round objects and come to the conclusion of a wave behind each hole. Then they explain it using particles as an example but use computer generation to do so. I've yet to see someone do a physical experiment with bowling balls and small marbles

[deehin]

If a particle is moving through a medium that it is creating a wave in, it can interfere with itself as in the double-slit experiment. Its location on the detector is determined by the location and direction of its greatest amplitude before it hits the detector.

[greggleadbeater]

Here's something I don't know if already been expressed:

Think of extra dimensional planes, like a 4th dimension, of the single photon beam, representing itself as an interference pattern out from the extra slit.
The slit that doesn't have any photons thru it, has an extra dimensional aspect,
paralleling simultaneously with the slit that has the photon beam. Thus creating the interference patterns.

So when only one electron is fired at a time thru only one slit over time, those single fired electrons have a corresponding parallel extra dimensional aspect as well, providing the interference patterns.

Extra-dimensional space Eg: Tesseract - Hypercube expression; of electron/photon beam.

[EvgenyMeshkov]

Everything exists for a precise reason. Too bad we use the word 'probability' so often. Even the formula he talked about shows that we know where and how much light will appear precisely (or almost).

hi im from the future and im lmao.  humans were so dumb back then.  rofl!
