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.

If you search YouTube for Jim Alkha-lili The Double Slit Experiment and fast forward the video to 8:00 you'll find out about ANOTHER version of The Double Slit Experiment that scientists did that kept everything the same ( including the detectors still being there and the light still being the same).The only difference in THIS version of the experiment is that the scientists unplugged the detectors and DIDN'T LOOK THROUGH THEM as they ran the same experiment.Afterwards they examined the plate at the back of the experiment and they found that THE WAVE FUNCTION WOULDN'T COLLAPSE BECAUSE THE SCIENTISTS WEREN'T LOOKING THROUGH THE DETECTORS.NOTHING ELSE PRESENT DURING THE RUNNING OF THE EXPERIMENT COULD COLLAPSE THE WAVE FUNCTION.Also THE ATOMS KNEW WHEN THEY WERE BEING WATCHED AND WHEN THEY WERE NOT BEING WATCHED.
Stupid nonsense video..
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.
Is this Box from Logan's Run?
Fantastic video, I have always wondered about this experiment and have never seen a video that explained it’s significance as well as this one.
I enjoyed the video but the one who made it is too set on ray-traced reflections. Nice to have a Terminator 2 type head explaining and all that but making the barriers reflective just muddles the image.
Dr Quantum Died and came back as a flying head
why does he have the infinity stones?
It's not interference, it's the wall in the middle of the two slits that cause the dark areas. the particles bounce off the sides of the slits and land where they will, but by opening two slits, you introduce a middle column which will appear as dark areas.
Wtf?
Spooky -AF
Has anybody actually been able to shoot electrons through real slits in a laboratory
Ya this script is a copy of the Dr. Quantum video. https://www.youtube.com/watch?v=fwXQjRBLwsQ
Wait this is literally just Dr. Quantum but scary!
very simple break down
it's like when you catch someone taking a shit in the middle of nowhere,the fact that now they're being observed will totally change that moving turd's behavior,because once that turd exits the anus and it's exposed to the atmosphere,it becomes subjected to all physical consequences,here the exiting turd loses all probability of landing on top of the previous turd,by the sudden action of the consciousness that owns that particular anus,isnt quantum shit awesome??
How do you fire a single electron ? And how can you observe it without interfering with it ?.
ok am I the only one who isn't terrfied of this things floating head
Delayed choice experiment
there was absolutely no need for the floating head. a waste of money and time, and was absolutely cringy.
This video is entangled with Dr Quantum video.. ?.
there is no matter
In regards to mystery how an atom behaves wave function and collapses as particle when observed. The answer seems absurdly in plain sight what already has been discovered. There is no material Atom in the first place and its just an illusion and our mind’s perception that we have an Atom, which we shooting out of gun…
I feel ‘Double Slit’ experiment proves ’String Theory’ / ‘Universal law of Vibration’….. and ’String Theory’ / ‘Universal Law of Vibration’ Explains ‘Double slit’ experiment.
Common sense says, we are surrounded by huge ocean of energy which like sea waves, vibes accordingly by the frequencies generated by our brains, some genetically pre-set and others we acquire personally / physically or socially over time.
It’s not the Atom that is pre-reading the mind of observer but it’s the mind of observer creating the Atom itself.
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.
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.
What happened to Silver Surfer
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
copying Dr.Q's video ver batem to what…. get views and subscriptions?? so lame.
Does Dr. Quantum know you clipped his homework ?
I've never seen a demonstration showing the spooky result caused by watching the electrons (or photons) pass through the slits.
Show me what you got!
Finally
I bet this guy graduated at the HEAD of his class….
I thought idiocy couldn't get any lower – then I found this. I feel so sorry for young people having to be treated like morons – by morons.
The interpretations are in both the light and particle models of double-slit experiments are flawed. First, nobody has performed definitive experiments to test whether the pattern formed by light is actually interference or whether instead photons are being scattered at discrete angles. Second, the fact that the pattern with particles disappears when a detector is added can be reasonably explained. The action of a detector would necessarily have an effect on the particle such as an electron (Newton’s 3rd law). The detector would then translate that event into a current which is sent to the counter. When the counter is turned off, the circuit would be broken and so the detector would be unable to exert its effect on the electron (again, Newton’s 3rd law). Thus, any interactions with the surface of the slit that results in the pattern would be interrupted only when the detector and counter are functional. This would suggest it has nothing to do with whether it is "observed". It would be testable, simply by blinding the observer to the results of the counter, but so far as I have been able to tell, that has never been done.
still haven't seen a real life experiment filmed showing the break of interference due to observation.
Um, is that Destro? I'm pretty sure that's Destro…
copied off of Dr quantum
everything alright with this video but the ending part (4:90 and on) isn't correct.
Actually the floating head in a plate is more bothers me than the strangeness of the quantum ^_^
one simple question that bothered me is how is it observed without creating a interference pattern… think of How this would Have to be observed. how would it not have a effect upon the outcome? there's nothing mystical about it. they do not visibly observe the outcome. the pattern had to be effected by the mode of observation. if you cause a wave pattern, expect one. If you want funding overlook the obvious I guess.
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.
Did Dr. Quantum die and come back as a flying head of probability?
any measurement will collapse the wave function. machine measurement or human observer. why are people trying to make it seem less significant? its fucking amazing you dipshits, get over it
What do you expect? Mark Zuckerburg, the cheif honcho of FACEBOOK is a Muslim.
Where is the paper that describes the experiment with detectors inside the slit? I never saw the raw data with single-electron-at-a-time experiment.
