We now examine a phenomenon, which is absolutely impossible to explain in any classical way, and which is at the very heart of quantum mechanics; the famous double slit experiment.
To understand this experiment we first need to see how ordinary particles, or little balls of matter, act. If we shoot small objects, such as marbles, at a screen containing a single slit, we see a pattern form where they went through the slit and hit on the back wall.
Now, if we add a second slit we would expect to see two bands directly behind the slits. Now, lets look at waves. The waves hit the slit and radiate out striking the back wall with the most intensity directly in line with the slit. The line of brightness on the back screen shows that intensity. This is similar to the line the marbles make.
But, when we add the second slit, something different happens. If the top of one wave meets the bottom of another wave, they cancel each other out. So now, there is an interference pattern on the back wall. Places where the two tops meet are the highest intensity, the bright lines, and where they cancel, there is nothing. So, when we shoot particles, such as matter, through two slits, we get this. Two bands of hits. And, with waves we get an interference pattern of many bands.
Good, so far. Now, lets go quantum. An electron is a tiny bit of matter. Like a tiny marble. Lets fire a stream through one slit. It behaves just like the marbles, a single band. So, if we shoot these tiny particles through two slits, we should get ... like the marbles ... two bands.
What? An interference pattern! We fired electrons. Tiny bits of matter through. But we get a pattern like waves. Not like little marbles.
How? How could pieces of matter create an interference pattern like a wave? It doesnt make sense. But, physicists are clever. They thought maybe those little balls are bouncing off each other, and creating that pattern.
So, they decide to shoot electrons through one at a time. There is no way they could interfere with each other. But, after an hour of this, the same interference pattern is seen to emerge. The conclusion is inescapable. The single electron leaves as a particle, becomes a wave of potentials, goes through both slits, and interferes with itself, to hit the wall, like a particle.
But mathematically, its even stranger. It goes through both slits, and it goes through neither, and it goes through just one, and it goes through just the other. All of these possibilities are in superposition with each other.
But physicists were completely baffled by this. So, they decided to peek, and see which slit it actually goes through. They put a measuring device by one slit. To see which one it went through, and let it fly. But the quantum world is far more mysterious than they could have imagined.
When they observed, the electron went back to behaving like a little marble. It produced a pattern of two bands. Not an interference pattern of many. The very act of measuring, or observing, which slit it went through, meant it only went through only one not both.
This led to many questions. What is matter? Marbles or waves? And waves of what? And what does an observer have to do with any of this? It was as if the electron decided to act differently, as though it was aware it was being watched. It seemed as if the observer somehow collapsed the wave-function, simply by observing.
However, physicists eventually realized that any type of measuring device, no matter how small, always interacted with the electron, subsequently destroying the interference pattern.
Werner Heisenberg proposed a new uncertainty principle describing this. The Uncertainty Principle can be stated in terms of our experiment as follows:
It is impossible to design an apparatus to determine which slit the electron passes through that will not at the same time disturb the electron enough to collapse its wave-function, destroying the interference pattern.
And it was here that physicists stepped forever into the strange, never-world of quantum uncertainty.

This is the same as the Dr. Quantum video, except that it explains at the end what Heisenberg said (from Feynman's lecture) : “It is impossible to design an apparatus to determine which hole / slit the electron passes through, that will not at the same time disturb the electrons enough to destroy the interference pattern [collapse the wave function].” One of the most misconstrued terms used to explain the double-slit experiment is "observe." This doesn't simply mean we're standing across the room and looking at an electron passing through the slit. It means we are taking a measurement of its position or momentum. Andrew Thomas does an excellent job of explaining "observation" at a quantum level:
"How would we measure the position of the smallest, elementary particle? We could only do that by interacting with it, by getting the original particle to collide with another (measuring) particle - thus inevitably modifying the very position measurement we were trying to obtain! [The interaction between the detection apparatus and the electron affects the behavior of the electron, since quantum entities are so small that even contact with one photon will change their position or momentum]. Even with large objects we have to modify them when we take a measurement. For example, when we take the temperature of an object we have to remove a small sample of heat from the object. Or when you check the air pressure in your car tyres you have to take a bit of air out of the tyres. These effects are so small with large objects that we do not notice them, but we can't ignore these effects when we deal with quantum objects."
+McAllister Pulswaithe , excellent observation! ;-) I totally agree with you that the word "observe" or "observer" can be very misleading, especially when some examples use an eye to depict an observer, implying the observer is just watching and not interacting with the subject. Also, good job on pointing out that "measuring" in this case involved interacting with the subject. Personally, I don't like the word "measure" either because there are many cases where we measure something without interacting with it. We do it all the time in astronomy and cosmology.
so, how do you explain the fact that scientists actually let the measure device be on just without collecting the actual data to see if the patterns behaved the same way then. Which mean the measurment device had the same interference as before just not recording the data. The pattern then broke up in multiple stripes. When they then did nothing else to the measurment device except actually record the data, it again changed the pattern to two single stripes.
Interesting distinction. Without it, the Deepak Chopras of the world are associating the idea of "consciousness" with observation, taking it even a step further into a gray area. They hypothesize that it is somehow that mind is interacting with matter in order to produce the results. Personally, what I would like to see is exactly what sort of "interaction" was taking place in the measurement of the position of the electrons. The experiment seems always presented in a way that not only obfuscates the methodology, but also fails to show the actual evidence in the form in which it is collected, presumably on a piece of film.
It's also unclear in the many presentations I've seen what is meant by "measuring" in a way that would show exactly how the measuring device might have interacted with the experiment. All presentations seem to make it out to be such a mystery without giving enough information to attempt to solve it, even hypothetically. If it is true that (as many suggest) that consciousness is involved, then it should be fairly easy to control/double blind that to show whether consciousness is involved.
The alleged methodology of measuring only the photons coming through one of the 2 slits would seem to be insufficient to collapse the wave function of particles coming through the unmeasured slit in any case. Yet, as presented, ALL of the photons look to have their wave function collapsed, including the non-measured ones. If anyone knows otherwise, please comment.
It would seem that if only half were measured, then the other half would go on without collapse. If a second filter with 4 slits were placed AFTER the first filter, and positioned and sized such that one set were directly in line between the light source and each of the original 2 slits, and a barrier is placed between each set (so no interaction between the two sets), then it would be interesting to see if the resulting pairs produced 2 line or multi-line patterns, AND if they were the same. We could predict that the "never interfered with" pair would produce an interference pattern. But it would be especially interesting to see if the originally "collapsed" particles continued on to "uncollapse" their wave function. Anyone know if this has been done?
Why don't air molecules 'disturb' the photons then?
What makes a particle from a measurement device different from regular air/dust particles?
Plaar i had also the exactly the same problem,if you know the answer now please share
Did Dr. Quantum die and come back as a flying head of probability?
ModestConfidence we are not allowed to ask about Dr. Quantums life, or lack thereof. We can only ask about the probability of him being a flying head of probability, probably.
its like every word is repeated verbatim ruclips.net/video/DfPeprQ7oGc/видео.html
nope.. this is dr manhattan.. totally different person
The question I think he is indirectly proposing is, would we exist if we were not being perceived? Is it the very act of perception that causes things to manifest materially. If that is so then who is perceiving? Is it all life accumulatively? or is it one higher being? whatever "it" is it is not a thing. It is a "personality" or a "them" or an "us".
There needs to be dramatic music playing at the end when the camera rotates and we see, in the reflection, that floating silver-head has been talking to itself this entire time.
The "Uncertainty Principle" does not debunk the theory that observation is what collapses the wave function into particles. Do a search for "Quantum Eraser Experiment." Essentially, the Quantum Eraser delays the choice of whether or not we know which path was taken by the particle until after the screen pattern is formed. The apparatus is monitoring the particles both when an interference pattern occurs and when it does not occur. The apparatus is uniform in both cases and the ONLY difference is whether or not we know the path.
@@margarethacker4982 oh god... It's that li'l jr. High school thing again...
Yeah, it's well understood mathematically... Now Explain it.
@@margarethacker4982 yeah I just re read that awful thing. It says nothing about Why the DCQE was conceived; and like all those who disrespect von Neumann and his ilk, never actually addresses Why people start talking about consciousness in this context. But you have to fully apprehend the double slit experiment to understand the DCQE, and he obviously doesn't. Haha, he probably believes that thing about having to probe an electron with a photon causes collapse of the wave function.
This video is entangled with Dr Quantum video.. 😱.
It’s also entangled by Jada Pinkett Smoth 😂
This one is clearly Older!! 13 yrs!!
Dr. Quantum is just 9 years!
Actually the floating head in a plate is more bothers me than the strangeness of the quantum ^_^
Hahahah🤣🤣🤣😎👍
The double slit experiment proves the universe isn't what a lot of people think it is. There is no way to make sense out of photons changing based on our observation. I see many here think up scenarios to explain it, but those hypotheses have been proven wrong. If you research more videos, you will see that. It has been proven, just exactly as this video says, that it truly is the act of observing that changes the nature of a photon. This is intelligent design folks, very clearly.
just saying that the head got to much reflection, :P
That floating talking head was kind of creepy. That oldschool computer animation takes me back, though....
My chemistry teacher showed my class this video and we all burst out laughing because of the way the head that looks and turns and she said we're the first class act like that for her.
So if a tree falls in the forest and no one is there to hear it does it make a sound?
Would it make a difference if the sensor recorded the passing photon on the other side of the slitted wall? Essentially letting the photon choose its direction uninterrupted and then recording the outcome on the other side.
I also heard the comment about them deciding.
But his wording was not sounding like he wanted you to think that they thought.
He was saying that they act as if they think, but then he goes on to explain that they are really just being interfered with by any object nearby, the sensor.
Its a hard subject to explain, and I think they explained it well.
You may get a fundamentalist who chooses to misinterpret, but those people are helpless and you cant really help them no matter how you word it.
I noticed too, it is very similar. However they have removed the "quantum quackery" at the end of that video and made it more scientifically correct, that's a welcome change IMO.
In order for the sensor to detect the particle some of the particle's energy is absorbed by the sensor.
Try experimenting at home with a flashlight and varying the size of the slits. The two separate slits are causing the electrons to change their behavior from particles into waves.
The detector dosnt take energy from the electron. Use any measuring device. Hell shrink down and watch it yourself.
@@infamouszephon There have been subsequent experiments in the intervening 12 years since my comment. It seems that there is confusion about what a "single particle" is exactly.
www.popularmechanics.com/science/a22280/double-slit-experiment-even-weirder/
If a "single photon" can be split into two, then that shows that our idea of a "discrete particle" is a misleading us. The measurement of a "single particle" is better understood as a discrete amount of energy. Photons can have varying amounts of energy.
www.nature.com/articles/srep04685
When you "detect" a "particle" you are measuring the amount of energy that impacts your detector. A "particle" will lose energy from interacting with other "particles" which is what the detectors are measuring.
home.cern/science/experiments/how-detector-works
Consider that the observing is a confounding variable; such as the light used to see the particles impacted the speed of the particles and hence it presents as the particle pattern as opposed to a stream/wave pattern (much like slowing down a running tap). Or perhaps the observing tool creates an electromagnetic field that impacts upon the particles hence altering the resulting pattern. This leap to "perhaps some how the particles know we are observing them" is very unscientific. Would be good to know if they corrected for the above mentioned possible confounds before assuming the improbable
All matter is made of packets of waves. The electron (a type of wave packet) passes thru both slits not one or the other. Detecting the wave packet at one slit, alters the wave packet in some way and prevents the interaction between the two waves.
Wow, this is amazing stuff. I am glad you put this up. I have always wondered about the slit experiment. I am glad this was so well explained.
This is the best ever explanation about the double-slit experiment
The important question is how do you observe which slit the electrons are passing through? If it's done by recording some electromagnetic effect by the detector, then there must be some sort interaction between the electron and the observer. The electromagnetic signal which has been recorded has an energy level, so there must have been a transfer of energy from the electron to the detector. This can explain why observing the passage of the electron changes the pattern it makes on the screen.
Another experiment to demonstrate the existence of quarks is to decompose the light beams as flip-flop particles according to some private investigations already done ... in which you find that the light or rather: reflected luminance product of an energy source is actually in more than two places simultaneously. In other words, quarks are the beginning of a new theory that will bring down relativity. since the field of gravity is not present in all sectors of space.
my theory, matter is like water waves, it moves up and down like a wave, but when an observation unit is set in place it absorbs the energy (in order to detect something that something needs to give off energy to be detected) and that loss of energy makes it go in a straight line. now I just need some equipment to test this thorey.... I'll get back to you ^.^
@HowellBarclay The electron experiment is done in a vacuum (extremely small and narrow tube, not like this video shows, but same idea). Photons have no mass, so they pass the air, they don't travel along it. Photons, although truly mass-less, are affected by gravity at extreme levels (i.e. black holes are black because they even affect light).
The video did vaguely mention this. However, it should have been explained further.
"However, physicists eventually realized that any type of measuring device, no matter how small, always interacted with the electron, subsequently destroying the interference pattern."
"It is impossible to design an apparatus to determine which slit the electron passes through that will not at the same time disturb the electron enough to collapse its wave-function, destroying the interference pattern."
Zetimenvec,
I didn't mean to imply it was a problem with quantum mechanics, my complaint is that this video is ripped from a Dr Quantum video. If you look into Dr Quantum you'll find Fred Wolf who talks about the interrelation of consciousness and quantum physics.
His works include The Spiritual Universe, Mind into Matter, Matter into Feeling ,The Yoga of Time Travel: How the Mind Can Defeat Time.
I think if that experiment would be replaced with a canon sand( not laser canon) would happen the same thing. It means : the experiment doesn't show anything because sand is particle, that( same thing ) would happen with all things as : water, sugar grain,salt grain, sand grain etc...( the photon doesn t interfere with itself but crashes with border of slit part (ricocheted the lips/borders of the slit )
How do you know it turns into a wave if you cant observe it?
Because it was moving like a wave Until we observed it. But it had to be Moving like a wave to make the... Well.... Wave pattern. When we 'observe' which slit it went through before it hits the back wall, it hits the back wall in the particle pattern, not the wave pattern. So in the first case; it had to be behaving like a wave before it hit the back wall.
part 2:
what if you purposely interfere with the wave pattern? keep moving the observation device closer and closer, and see how the final results change depending on the distance of the observation device
They did something similar. They turned the machine on after the particle went through the slit but before it hit the wall. What appeared to happen was the electron somehow goes back in time and does the same thing as if we observed it. Even crazier huh?
instead of measuring the particle going through the slits.....fire one particle at the slits and capture it as it splits to go through both slits at once. A single particle might be captured as two particles as it passes through the slits.
Or cover the slits with a thin membrane...then fire a single particle and see if it busted a whole through both sides of the slit. Like a kid throwing a rock through a window you can see the damage left behind.
I hope teachers are all like this one in the future; then we could throw the teacher around the classroom like a frisbee when we had questions.
I have a problem with the "observer" debacle. How does one NOT observe, or is it just observing with a camera up close as opposed to afar with the naked eye? Nobody observes until the final result?
There seems to be so many interpretations of the double-slit experiment. From my understanding, the electron is believed to take every possible path simultaneously connecting its firing point to the screen - it has no definite position, only when observed. I believe that the uncertainty principle is due to Plank's constant which deems we can not measure simultaneously two complementary variables; it does not have anything to do with the act of measuring the position as it emerges from the slits.
So does this mean that when we observe the universe through our senses, that the way we perceive matter causes the potential waves to collapse into the particles that fit our view. And consciousness itself is directing the universe?
still haven't seen a real life experiment filmed showing the break of interference due to observation.
Exactly. I want to know how they measured, and if anyone has figured out why the measuring process broke down the wave function. Geez, they've had almost a century to figure this out!
There is something about the uncertainty principle that states you can never know where a particle is and know it's velocity with absolute certainty. The more you know about one, the less you know about another. It makes sense if you think about all matter as superpositions of waves.
what device was used to observe? since it was the variable in the experiment, maybe the type of matter of the device used to observe was the one interfering the electrons causing them to act like marbles, instead of like waves.
Human double slit experiment.
For many years, I met a friend with the same spiritual name as mine. While speaking, I acknowledged much congruency. After dancing meditation, he sat across to me against a wall, as I did also.
A question arose inside of me: Who is the other being?
Now, I asked myself who are you? Where he immediately disappeared. My eyes were open. I felt my self as being present and he was gone out of sight. I saw the wall and some dancers. Moreover, I DID NOT SEE HIM ANYMORE. I shook my head and he was there again.
Where I again asked myself: Who are you? With the result, he was gone again.
Astonished I went out of the room, asking myself why does this happen.
Finally, I found that the mirroring aspect did not function anymore. I could not see him, because I did not ask him whom he was/is.
Now I meet often scientific doubled split experiments. Where I now can view this experiment out of another spiritual position.
. There is a position of the observer projecting and a position of the receiving wall, where in between those slits are present.
. There is a position of observing inside a human being, where the "wall" is also inside.
. There is a position of receiving inside a human being, where an inner instance perceives.
The pre-conditions for a material and/or spiritual doubled split experiment are:
Visible light is a wave of points, where these waves embraces a frequency, vibrations and distance. The points of the waves do not touch each other. Thinking and sensing happens.
Invisible light has no-waves, so base on points, which are bound with each other. Feeling happens by the lines of space-time bending.
The spiritual human experiment for visible light.
In this case, I as an observer am visible light.
I am situated inside the back part of the split big brain.
In this case, I am bipolar (split, dual) light.
I have two eyes at the front of my big brain, where my eyes are the doors/slits for mirroring the inner world of my bipolar big brain and the bipolar outer world. Where I move through my big brain as a projection.
Mirroring.
Looking inside a mirror it is obvious that by touching mirror glass with my left hand, the mirrored right hand meets my left hand. Of course, this happens with all extremities. However, it is remarkable that this does not happen with my nose, because it is present inside the midst of my body. Here is found an entanglement by extremities and an alignment by the midst.
By the way:
Such a mirror absorbs much of visible projected light reflected, which does not pass the mirror.
The eyes.
It is possible to observe with the right eye, the left eye, with closed eyes and with both eyes.
Closed eyes help to observe of what is going on inside the big brain. Therefore by night and by daylight.
By two open eyes, it is very easy to lower the upper eyelid on many positions, even until the eyes are closed. This has an impact on observing the observed.
By one open eye and one closed eye, it is impossible for me lower the upper eyelid in different positions. Maybe this is for other human beings possible? A total closing is possible easily.
I am talking about healthy eyes, where otherwise some muscle injuries could affect the impact of the eyes. Also must be recognised that glasses or other means for helping to observe right cover many eyes. For sure, the eyes now are not healthy enough.
The eyes are now in fact the slits inside a wall, representing the slits.
The outer wall receives the light send and is here not a mirror, as showed above. Scientists have to interpret here.
This is shown by all scientific doubled slit experiments.
The process of spiritual observing.
Observing happens by visible light of wave-points passing through a distance, where inside this distance visible light is present in all varieties of colours. This happens inside the big brain.
A perceiving process inside differs.
Both eyes.
I as the observer move myself (light particle) from the back of the split big brain. Pass through the "doubled" big brain. Pass both eyes into the outer world.
The nerves of the eyes are crossed over related with the back of the bipolar big brain.
The observer moves as carried by a light particle, which can have a colour or not.
Because of the waves and frequencies inside the brain, I observe and recognise the outer world. Here a distanced observation becomes accepted as a perception. Moreover is in fact a perception with a certain uncertainty.
By the eyes a rainbow is observed and recognised inside, where the wave of colours appeared by broken white light. This must be possible also by a scientific slit experiment. I am curious when a scientist could arrange this.
Anyway, my spiritual experiment confirms the scientific experiment for both eyes, doubled slits
One eye.
For hitting a point in the outside, so not a wave, the human being must focus on such a point.
This is done by a laser-light used by scientists, projecting one light particle through a slit, now hitting the wall as a particle.
A sniper, using one eye and closing the other eye, does this also. Such a sniper hits a point even when this point is moving as a wave.
Olympic shooting by bullets and arrows happens the same way by one open eye.
Now, my spiritual experiment confirms scientific experiments for one eye and one slit.
Results.
The results of doubled scientific slit experiment is observed, where a colourless wall received the projected signs of a point or/and of a wave.
The results of a doubled spiritual slit experiment is observed, where a coloured wall (subject) received the signs of a coloured point or/and of coloured waves.
Amount of experiments.
Many scientists showed their experiments clarifying what happened.
I now ask them, whether they are aware of the fact that they copy a procedure of observing all day long with their own spiritual eyes.
Is it not remarkable that all living beings with eyes do this the same way!
So what is the mystery?
By the amount of human beings on earth of ca. 8 billion people, they are observing and experiencing all what is all around and even can discover of all what is happening inside.
It is for sure so that very less people are aware of this self-experiment, which happen 24 hours a day! Now it is possible to use the doubled slit experiment for becoming aware and conscious of whom/what I am.
When I look a bit closer,
in this case, I am a steadily slit experiment.
Still the concern is scientific and spiritual experiments happening inside visible light for observing related with a distance. Here I miss the transcendent position of the perceiver.
Regarding to my experience of not seeing any more my partner, as clarified above, I now can say: My observing impact was not any more directed to the outside, concerning my partner, because I did ask it my self. Therefore, it was logical that I did not observe him anymore for some time and did not see him.
More bipolarities.
Besides the two eyes, there are two ears, two holes inside the nose, two arms or two kidneys etc. Now in a spiritual way, the holes inside the nose and inside the ears are a part of a double spiritual slit experiment also! This also can help to become aware of what/who I am.
The midst.
Between the slits inside the wall, there is a midst. In between any distance, there is a midst, as shown by the mirror clarification. Where by the extremities/dualities/bipolarities all the many sense organs are used, now I say that there is only one feeling organ, presenting itself in the midst.
That means, observing happens by sensing and thinking, where perceiving by feeling is the most important happening inside life.
However, the attention all over the globe is in connection with observing, where only a view people are aware of the difference between sensing and feeling. Therefore is observing related with a double split and must perceiving be connected with a singular split.
The singular experiment of felt light.
I meanwhile experience an inner perceiver, which I feel as being situated inside my middle brain. Because inside feeling there is no bipolarity anymore, I must state this is the instrument responsible for feeling singularity.
By this singular feeling, it is possible only to experience the related singular feeling inside a partner. The one who is at home inside this singular feeling can feel the singular feeling of the partner, even when this partner is not aware of it.
That is a complete different experimented story as the known doubled slit experiment.
I wanted to show how this double slit experiment is active for all inside spiritual universe, where a spiritual evolution is happening.
Therefore, I am an organism by observing and perceiving.
Its AMAZING!!! This proves that nothing in this Universe works without being observated by a bigger and powerful consciousness. We humans are indeed being observated.
hi! Can you further explain how this proves that nothing in this universe works without being observed.
@Danisfail "It wasn't because it was being watched, it was simply because the measuring device interfered with it" - Then explain the delayed choice quantum eraser experiment where the only measurement is made on an idler photon AFTER its entangled signal photon has already been absorbed by a detector, and the signal photon STILL, before any measurement is made, either shows the interference pattern or not, depending, seemingly, on whether or not we make the measurement in the future.
Dr. Quantum verbatim. Wow
I'm confused.
Firstly what is a device that measures electrons and secondly how does measuring which slit the electron passes through cause interference?
Does it have something to do with the electro-magnetic force as presumably any device to measure electrons would be electrically powered?
I wish there were physicists who would comment on the BestofScience's video series because it seems to be predominately ppl like me with some science education but still struggling to understand.
Could this experiment be explained if we had an emergent interactive process unfolding photon by photon? This idea is based on: (E=ˠM˳C²)∞ with energy ∆E equals mass ∆M linked to the Lorentz contraction ˠ of space and time. The Lorentz contraction ˠ represents the time dilation of Einstein’s Theory of Relativity. We have energy ∆E slowing the rate that time ∆t flows as a universal process of energy exchange or continuous creation. Mass will increase relative to this process with gravity being a secondary force to the electromagnetic force. The c² represents the speed of light c radiating out in a sphere 4π of EMR from its radius forming a square c² of probability. We have to square the probability of the wave-function Ψ because the area of the sphere is equal to the square of the radius of the sphere multiplied by 4π. This simple geometrical process forms the probability and uncertainty of everyday life and at the smallest scale of the process is represented mathematically by Heisenberg’s Uncertainty Principle ∆×∆pᵪ≥h/4π. In such a theory we have an emergent future unfolding photon by photon with the movement of charge and flow of EM fields. This gives us a geometrical reason for positive and negative charge with a concaved inner surface for negative charge and a convexed outer surface for positive charge. The brackets in the equation (E=ˠM˳C²)∞ represent a dynamic boundary condition of an individual reference frame with an Arrow of Time or time line for each frame of reference. The infinity ∞ symbol represents an infinite number of dynamic interactive reference frames that are continuously coming in and out of existence.
ok, what about this? its kinda hard to explain but, the protons somehow jump into the forth dimenion, when we try and place a messuring device there. measuring devices can only measure the 3rd dimention. relitivaty suddenly realises that the whole thing doesent work and so it quickly goes back into the 3rd dimention againgiving the 2 slit effect again. theres a big gap... but im thinking..
1:48 “Now, let’s go quantum”
Cameras work by bouncing photons off an object. The reflected photons are captured by the camera's sensor/film. Photons are powerful enough to collapse the wave function.
The silver surfers disembodied head is the best teacher.
The double slit experiment is very simple to understand. Particles can't exist at C and are a wave of possibility in future location and time.
Maybe if the world wasn't this weird, watching us try to work out what's going on wouldn't have been entertaining for god to have bothered.
Hello sir, how are you doing tonight? Might I please respond to your comment?
I did say the "evolution" but could just have easily replaced that with any naturalistic explanation for why were here. But you're right, you did not specifically mentioned evolution.
And I believe in making rational decisions, very much. So I think we both feel that's important.
On your other part, Yahweh has revealed Himself to us in ways others have not. It's not "silly."
There are many interpretations of quantum mechanics that try to explain this effect. My favorite is The Transactional Interpretation (google it, it's interesting), where particles interact via waves which "handshake" through space-time.
There are cameras that can take pictures of things like that and you can enlarge them. There are also detectors that can detect if a photon passes through it. (can't answer the rest but could answer that). In fact the large hadron collider smashes particles together breaks them into smaller particles and takes pictures which are then magnified.
I know the answer....and it is sooo unbelievably simple it will blow your mind. Everybody just over-thinks it. In fact, I refuse to believe no one has thought of it before. I am therefore leaving this comment as a record for future refrence.
Silver Surfer's head know a lot about physics.
an electron has a negative charge, so you could set up a coil so that as it passes through it could induce a currentit is possible that the current created which measures the elecrton interferes with the electron, as a current produces a magentic field.
so basically, electron passes thru coil, current is produced which is measured, the current produces a feild and the electron is disturbed
@XxzeldawolfxX All he says is "Some scientist we've never heard of has concluded that the observation device is interfering with the particle". He doesn't explain HOW its interfering with the particle's wave function, or why it even interferes with it. Thats the whole point. Why does an observer interfere with the wave function. You're clearly missing it.
Could you please do a video about Quantum Eraser. It actually contradicts this one a little bit, because it *does* matter if we 'observe' or 'interfear'.
"Perhaps we need a material that we yet to discover to use for experiments like this one were we want to look at electrons with out using electric instruments"
The problem is, it can't be done, hence the Heisenbergs uncertainty principle which state that it is impossible to measure both position and momentum at the same time. That is not a statement about the limitations of a researchers ability to measure, but about the very nature of the particles themselves.
This is THE MOST BASIC (and most necessary) sentences that one uses to explain such peculiarities of nature. They could have made it more perplexing by invoking new words and confusing the already befuddled audience. They can get original (...can only introduce new "words" or "explanations") only in a 4 year (or more) course, whereby they will explain each and every word that they are gonna come up with. One (probably) cannot get more elaborate than this in a meager 5 minute video.
Is this apart of parallel universe theory? so if we watch the proton it only goes through one slit, meaning in another universe it goes through the other? I'm probably wrong, i don't understand much about parallel universe, but knowing this makes me think it links the two together.
Ok if a photon travels in all directions simultaneously as a wave, and only materializes as a particle in a spot which is being observed... try this.. Put the emitter in an opaque sphere with the two slits. Do not observe the two slits, or what goes through the two slits, but instead measure the rest of the inner sphere. Do particles appear all around the emitter? If so do they make a pattern or just randomly appear all around. Lets see the results.
this is an excellent video. a brilliant explanation of the double slit experiment.
Wow, this video is informative because it explains the thought process of the physicists with clear exmaples. I understand now.
we are made of matter and vibration does that mean once we start observing our selves we will start acting differently? Because we are observing hum...
Maybe its just leaving a wake on some level that can't currently be measured, when the next particle comes along through the second slip it interacts with the wake left by the first and so wave pattern
Listen to the text. It's almost entirely from the What the Bleep video. I understand that the Twin Slit Experiment has been around since about 1809 and much has been happening more recently, and that it's important for people to know this stuff. I just don't understand why the author didn't use his/her own words to explain it. Why plagiarize?
I have always liked the quantum world even with Einsteins reservations.
P.S.
Cool video ★★★★★

An electron has spin & it orbits a nucleus. To strip it away from it's nucleus stops it's orbit, but not it's spin. That is the "matter" used in this experiment.
The University of Geneva split a quantum particle & "shot" each 1/2 particle 7 miles in opposite directions. They then physically changed the "spin" of one half & the other half (14 miles away) instantaneously changed it's spin - faster than the speed of light - proving some type of "entanglement". Crazy yet?
Peace.
@minteko
Electrons are not self aware. They act as a wave until disturbed. Observing quantum events require disturbing the observed particles that collapse their wave-function, thus making it behave as a particle.
Holy crap something just blew my mind - Maybe when you experience a certain reality your mind will perceive that everyone else is also connected to this reality even though its just one of many realities...In other words maybe consciousness is so powerful that it can interpret information however it wants to the point where you are going through an experience that has little to do with anything but you...
Bro i know this comment is 7 years old but that blew my mind lol
harshm2u,
I don't understand your comment to me... you could easily explain the double slit experiment without bringing awareness into it, without making it any more perplexing and without making up new words. I'm not asking for it to be any more elaborate just to check their sources.
My problem is they copied a known spiritualist word-for-word including all of his misleading sentences.
If you take time out of the equation the electrons wont be acting as a wave and wont be interfering with themselves but each other
This was good, but I prefer the more natural ones with an offscreen narrator (who always comes back for other episodes).
Yes the lesson is in what I wrote. Don't make up words if you haven't heard them before.You might've thought that word existed because it sounds like how one makes a word in that tense, but you were wrong.If you haven't heard the word used, or read it used,then don't use it.No literate person would use that word.It's also possible that you heard some illiterate use it (AS I SAID).In which case you shouldn't have learnt it from them anymore than you would learn how to spell from somebody dyslexic
I suppose it was only part of the visualiation that they had what seemed as quite a long distance from the slit to the wall. However your point is interesting. Would the pattern be different if the distance of the wall is different?
Observing doesn't simply mean using your eyes though :) , no scientist saw an electron go through any slit, we cannot see individual electrons, we use instruments to do the observing, either firing a stream of photons(light) and look for a dip in the amount of photons hitting the back plate, a receiver, the dip is the electron passing through the beam of light. No your eyes do not alter reality :).
Going back to our own individual perceptions... I just had a thought. What if time, energy, and perception were directly related? Our perceptions are completely unique and never accurate at the same time as always accurate. It all depends on what you are relating it to. Everything material follows material laws (such as relativity). So time is not necessarily a consistent flow. The overall accumulative flowing river of time may be, but time has also an individual flow for each perceiver?
and I do apologize if you are exceedingly more brilliant than you seem. Is there a new theory of yours involving refraction off of a single atom? in regular groupings? in exactly the shape of a wave interference pattern? That would be a curious thought...
Why don't they just say that time is irrelevant for things moving with the speed of light? So, simultaneously interfering with itself is possible. Even space does not have a meaning anymore in the "eyes" of a photon or electron or neutron. By now, the physisist know that the universe is made out of waves, not particles. We only perceive some wave functions as particles. Particles are an emerging property of the universe in the eye of the beholder.
@XxzeldawolfxX Yes, although he does say they came to the conclusion which led to the Uncertainty Principal. If they are uncertain and particles act as if they are self aware then what other experiment would show conclusive that the particle is aware or not? See Roger G. Vogelsang's STI device where he discovered that the particle is indeed aware.
Watch the jim Al-Khalili double slit experiment video - the last 1 minute is even more eye opening
So every electron is self aware, to the extent that it is being observed..
So what is the difference between the electrons we use to observe those electrons?
Interesting... I am having trouble rapping my brain around all that you said. Would you mind explaining a little further and simpler? or if you can refer me to a video, that works also. Thanks!
A single point on a 2d graph could actually be a line in a 3d graph, so doesn't it make sense that it could technically be in many places at once by existing in more than 3 dimensions?
ok i got a question what if you put someone in the room at the same time of doing the experiment and not letting them know about whats going on would it still act as if it is being observed???
Question? how do the electrons move across space. The marbles move atoms away to get to one point from the other and are affected by gravity. Do photons move across atoms like electricity, from one outer shell to another? They seem be resistant to gravity. Do this experiment in a vacuum.....
Can physicists a little bit change this experiment and install those electron/laser sensors not only at the end as it is now but also on the sides so area between the slit barrier and the back sensor is surrounded with another sensors from every direction? Maybe there will be also patterns on those side sensors and not only on the one in the video..
I see the problem. It's at 5:18 when dude said "It's impossible."
I'm sure he meant, "We don't yet know how..."
IT IS amazing how people find anything and everything as proof of a higher power of some sort. They will even slant and bend truths without realizing. I agree that there are many religious people with biased perceptions (all of them). You may not like to admit it, but your perception is biased also. For instance, when you posted that comment you completely missed the scientifically stimulating thought behind it all.
hold on now, this sounds more like the origional test was flawed. if we're going to say that the sensor apparatus caused the waveform to collapse, then why wouldnt the slit apparatus do the same? why wouldnt the sensor on the wall cause this collapse?
how doi you detect electrons?
for all I know, you have to make it hit something. The slit apparatus is not a measuring device, because we are intrested in electrons passing through the slits, not hitting the apparatus.
Any measuring device must be inside one of the slits and therefore would interfere with the electrons.
Well, thats how I see it, but I am not a physicist, so ask someone more competent in case I am wrong...
I don't think I could do the explanation justice in under 500 characters. I'm still working on the particulars of my theory as well as a working model that would explain everything without all of the mystical mojo. It is pretty simple though once you look at it differently. If you do want a better explanation of the double-split experiment though you should look at Richard Feynman's leture on it. You can find it on youtube.
Its a stupid question, but I am wondering how they know how it behaved without being observed?
isnt it obvious the particle split into 2 bands in our superposition yet it split off into another universe and created a interference pattern when we were not looking at it
.
Looks like an improvement of Dr Quantum to me. Far more concise. And, it doesn't dwell on this idea that the mere act of observation causes the collapse. It mentions and swiftly, that it's the measuring device (which I don't think is quite accurate either, though it's better!) . It's our ability to know that does it.
thats better than the dr quantams video ...it even explains what an observer is
Simpleton, the video improves it, by saying it's the detector that's the issue, not consciousness. Though now they've actually built detectors that don't interfere, thus showing heisenberg's uncertainty principle to be wrong. So quantum theory is less weird in that area. Thankfully
Um, is that Destro? I'm pretty sure that's Destro...
why do physicists deny possiblility that electrons are actually waves?
I know there was such theory, but one guy said that "the fact of observing electron, changes its position" and after that nobody ever questioned if its wave or not.
Even if all math works well, if we consider electrons as waves, maybe even better... (sadly im not physicist, i dont really know)
@XxzeldawolfxX
Unless you explain how a measuring device interacts with an electron then it is just a theory, not an explanation
