Double slit theory Quantum Physics Animation

[worker1]

Seems legit (not srs)

[alucardseras]

@worker1 you don't understand it?

[therabidliger]

can anyone explain this in depth?

[therabidliger]

@therabidliger and i mean as to why this occurs. what fundamental changes cause the electron to behave differently when we observe it?

[antischaap]

this is ok , but i prefer my double splif experiment :)

[stickfigure578]

Its not the fact that we are watching that changes it, but the equipment we use to watch the particles affects the way the particles act. So it's the interference of the equipment, not a magical force our examination

[sloz100]

im 12, watching this and understanding it, should i be worried?

[NoLastNameX]

@sloz100 no, your just average.

[ThePTB]

So basically, it's the Hawthorne effect but for Physics. Got it. Yeah, something Psychologists figured out long before you Physicists. So much for your "hard sciences supremacy", huh?

[pballskatelax]

@ThePTB no, not at all.

[Quartrez]

That's gotta be the only interesting and accurate thing of the whole documentary, so for those who have only watched the double slit experiment part, let me say that you did not miss much.

[thirumallic]

its very usefull for understanding//

[sagor9002]

nice



[TheAudioart]

How the photon will behave if you place two plates exactly after the two slits ?

[GreenScotsman]

Why did the video just stop. This concept was blowing my mind. Now its all fucking jumbled in my head and leaking out of my ears.

[TornTech]

So what happened! I want to know!

[Quartrez]

@TornTech It's the principle of uncertainty.

[beefking69er]

The big man upstairs is just messing with us.

[FantomL0rd]

@beefking69er I don't have an upstairs.

[TheQuantumMaverick]

Since the interference pattern is caused by a zone where the front-edge diffraction of the two slits overlaps (rather than by mysterious particle-waves that somehow interfere with each other), getting the same pattern by firing particles one-at-a-time no longer holds any mystery.

Particles do no split up, exhibit some mysterious wave nature, interfere with themselves, or interfere with other particles in any way shape or form. Anyone who believes they do is simply deluding themselves.

[TheQuantumMaverick]

Furthermore, experiments have been done as long ago as 1987 that prove you can detect which slit a particle has passed through without completely destroying the interference pattern – debunking the theory that particles mysteriously change their behaviour when we ‘look at them’.

In Summary: Disappointingly, the double-slit experiment is merely no more than a mildly interesting experiment on the effects of diffraction.

[TheQuantumMaverick]

This explanation was proposed by ‘Neo Diffractionites’ (found in a Facebook Quantum Physics discussion)

If a laser is aimed close to, but not above, a knife edge, some photons will bend over the top of the knife edge due to diffraction (demonstrating that diffraction starts at the front edge)

Thus if the slits are close enough (near the ‘wavelength’ of the oscillating particle), there will be a zone where the front-edge diffraction effects overlap; this overlap causes the interference pattern

[bryceguy72]

What if the electron-observing device is damaged or not turned on? The electron won't be observed even though the observation device is present. Will the electron act as a wave or particle?

[AJasinski3]

@bryceguy72 this is such a dumb question. obviously if it wasnt turned on or broken then the electron would act as a wave. a broken electron-observing device is about as useful for observing electrons as a dildo.

[TheHeretic333]

Mind over matter. in its simplist form. The rest of the mind over matter realization has been raped from you.

and all of you let this happen via religion. government. peir pressure.

we are missing trillions of pages of dna. and even with that. we only use 10% of our brains. Earth science has backed itself into a corner. Something is only proven true if it has a terrestrial explanation..

Shake the pillars of philosophy. Wake up earth scientists. You call this intelligent life?

[GJVChristian]

@TheHeretic333 lol. what? It's quite popular now to think of science as some sort of entity. Science is only people, just like you and me. It's no amazing solve-all-world-problems philosophy, it's merely people studying...and people (scientists) are just as flawed as you and me and have been known to make mistakes. Like "oops, science once told us our tap water was okay". Now it's not. Praising science is just a fancy way of saying "praising people".

[ZaPpaul]

@GJVChristian My tap water is fine, what are you trying to say?

[lazurm]

@GJVChristian Actually, when knowlegable people refer to "science" they are referring to a methodology.If this method is practiced as it is supposed to be practiced,the "people factor" should be controlled for.As for your example,the science involved measuring chemicals found in water. Whether these chemicals pose a hazard or not may change as more data accumulates. So, for example,more data may enable better controls for variables not realized earlier, hence the change of conclusions over time.

[GJVChristian]

@lazurm I wish all people knew that, instead of the mentality I usually encounter, not far from assuming scientists are a group of superhuman old men who exist in a world beyond ours and dictate our reality. I'm more of the belief that anyone can be a scientist, and in many cases you don't even need to be "smart". I find it a ridiculous creed that "science is always right" or the it's methods are beyond reason / question. It's probably wise to question everything, even almighty "science"

[lazurm]

@GJVChristian Apparently you have a profound misunderstanding of science.The natural sciences (geology,chemistry,physics,etc­.)study the world with methods that have, so far,the best track record at delivering truths about nature.They are not the ultimate truths, just the best there are to date,proven by inventions born out of the discoveries that came from this knowledge.Science isn't "always right",but,to date,the best tool to discover nature's truths.Questioning is what science is about.

[GJVChristian]

@lazurm What makes you think I disagree with any of that? Which part is a "profound understanding"? The part where I said "anybody can be a scientist" or that it's ridiculous to think that "science is always right"? Let me know....

[shenzhenprostitute]

My girlfriend has only one slit.

[thebeastmaster420]

Quantum mechanics, the dream stuff is made of.

[Clusterfuckkk]

this shit is insaaane. makes you think about everything differently, electrons and matter could be behaving differently when no one is watching them. incredible.

[LouisSammut]

TRIPPY

[LBromoHojo]

Sigh. The electron is not aware it's being observed. Please put an end to this magical thinking. "Observe" in physics means "hit it with a photon", which in this case causes an irreversible reaction called quantum decoherence, wherein the indefinite particle loses its superposition of states.

[TheInfinite91]

@LBromoHojo You seem to know what's going on here. So when they want to measure it, the electron knows it's being observed so it acts accordingly?

[LBromoHojo]

@TheInfinite91 Yes, consciousness exists at every level of abstraction within reality. >_>

[naneux]

@LBromoHojo but he(infinite91) said exactly what you didnt want the video to say which is:

That the particle knows its being observed.

"Sigh. The electron is not aware it's being observed. Please put an end to this magical thinking"

[GJVChristian]

@naneux I don't think this is "magical thinking" but more so an analogy. It's "as if" the particle knows it's being observed...hence, this is the point where more study is required. It may very well have some interaction with observation, for instance the electronic field produced by the observation device.

[naneux]

@GJVChristian Im not the one that said it was magical thinking, I was quoting...

[hankaaron1961]

@naneux I sort of agree with you, but I'm not ready to close the book on that. You should google the recent findings call "Quantum Ignorance".

[maggieclare]

WHAT? AN INTERFERENCE PATTERN!

[sedlfel]

pretty weird

[rEspanator]

i dont get why, when the electrons are measured they act as matter when before they act as waves

[Haokennxt]

Ridicuously brilliant video

[TerraP]

In this 5 minutes I learned more than in 2years of boring and grey physic class -.- THIS is mysterious

[congotree]

@TerraP I really doubt that, maybe more interesting than the topics you learned.

[TerraP]

@congotree

exact same topic ;) i just didnt know what my teacher was talking about back than ;) maybe because he wasn't dressed like quantum man!

[congotree]

I don't think the electron was aware that it was being watched, more likely the interaction of photons emitted by the measuring device...

[LordGrokk]

it just says "never ending world of quantum physics" at the end and goes to the next subject, dont get too worried

[GenoSkill]

@LordGrokk thanks man

[shenaynaybob]

@LordGrokk @LordGrokk thanks i was a bit frustrated and i still am but now my curiosity is satisfied

[deoxy999]

It's the same as CassopeiaProjects.

[Fatb0ybadb0y]

holy balls, what a bad place to cut it off

[KING20007009]

DUDE where's the rest of it ? I wANt IT !!!!!!

[electrum7]

DAMNIT!! This video used to play all the way thru WTF??!!!

[unclejnr]

I recognise the voice of the Doc, it's driving me mad, who is it?!!

[toni05sp]

@unclejnr your mom

[gamervgd]

this was so interesting.Awesome 5 stars

[CHAN4257MARIE]

good stuff ....as kloli sed where's the rest?

[klolipop]

where is the rest of it?

[OhDangShanny]

Its a movie called What the bleep do we know.

[Skibz93]

thanks this sounds intresting

[OhDangShanny]

No problem. I recommend getting the DVD set. It is very interesting and not that hard to understand. (:
