- Quantum physics deals with the foundation of our world - the electrons in an atom, the protons inside the nucleus, the quarks that build those protons, and the photons that we perceive as light. These constitute everything that we are made of, both matter and energy. But how is it any different from regular physics? The 'regular' physics is the physics that deals with Newton’s laws of motion and its related mechanics. This is more formally called Classical Physics.
This is the physics of our day-to-day lives-the rolling of balls, the rotation of the earth, and the mechanics of engines. Quantum physics deals with particles that are incredibly small and hence, the laws of classical physics don’t apply in this world. In this video, we discuss the meaning of quantum physics and how is it going to change how we perceive the world around us.

Hi bro😊
Nerd
Just finished the video! So what exactly is quantum mechanics?
Exactly 😂
The study and research of how particles of matter behave at an atomic [extremely tiny] level is called quantum physics[I guess]
The animation and sound effects were so good, I forgot to understand.
Loved the video and the explanation using "real" examples! Great job, Scott!
Would love a video explaining quarks. Keep the content coming!!
Quark was a short lived sci fi TV show that parodied Trek and Star Wars in the late 1970s starring Richard Benjamin. Also a Ferengi bartender on Deep Space 9. What did you hope to learn?
I really need this level of explanation of Quantum Physics. Much more and I glaze over. But isn't it the most mind-blowing thought that Gautama Buddha, alive 500 years before Christ, perfectly understood that there is no permanent 'me' or anything else. And observed it without any equipment or experiments.
Well I mean, this is very borderline philosohpy so it makes sense that certain thinkers of the past can correlate to this
I learned nothing.
Hi science ABC. Could you do a video on Loop quantum gravity. Other youtubers explain in a very complicated way, but maybe your explanation might be better
Great suggestion!
Any chance on getting a video on the Pauli exclusion principle if it is possible to attempt to simplify it lol😮
I tried to make a joke to a group of scientifically literate friends. I brought up the subject of Schrodinger cat. Then I said, "Being sealed in a box with a tin of poison is not a superposition to be in." Nobody got it.
Your friends are also in a state of superposition as they may or may not understand, because they may or may not be quantum literate, or even if they do, they may or may not care, therefore they may or may not laugh.
Well, you raise an interesting possibility but it was more the opposite. This group was mostly PhDs. They were so hyper focused on actually understanding the theoretical idea behind "Shrodinger's Cat", they missed the joke entirely. It's like I invented a cloaking device. BTW, what is a coat rack... but a cloaking device? LOL Why they let me hang around I don't know. @@HighMojo
It's safer for them not to laugh whether they understood the joke or not. A moan and a small smile would have been nice to at least acknowledge that you had attempted a joke.
This video explained both everything and nothing
😂
Thanks buddy. Love you. Continue to encourage beings ...towards my Quantum mechanics😊
Always!
I loved the pictures and animations used while explaining
Glad you enjoyed it!
An amazing video again! Thanks for the effort
Glad you enjoyed it!
Your explanations are so good bro, thanks for your videos ! ❤️
Glad you think so!
"“If you think you understand quantum mechanics, you don't understand quantum mechanics.”
So i'm in a superposition of both knowing and not knowing Quantum Mechanics?
Wow... you are the first person I have seen online who actually noticed that Feynman made a (poor) joke about superposition there! Congrats. You have a sense of humor. :-)
Particles seem to be aware of what’s going on. They can travel back in time to change an outcome. The double slit experiment is truly bizarre.
Indeed. We know it works. It's easily proven at home in a dark room.. But we don't know how
Finaly I understand that I will never understand quantum mechanics.
Hey the content is good but can you please stop the irrelevant animations and texts on the screen, it is very distracting.
Agreed.
I know the presenter is trying to make quantum physics intelligible to the layman but this video sounded (and looked) like something Kamilla Harris would have offered up.
(Just the cackling was missing).
I loved that
The animations and texts fit this video what are you talking about? It was relevant
Why don't you just read a book then, you know? Lol
No! Don't stop the irrelevant animations, they are the only reason I and a bunch of other subscribers too are here :)
nice videos, i have 1 question which software do you use for animations ..?
We use Adobe Animate for making these videos.
Love how he changed the levels
That was Amazing😍 love from 🇮🇳
I hate how much I would've learned in school, had my classes broke it down further, like this video. Thank you ❤
thanks a lot
What a great video!
Glad you liked it!
Video was good but you not told about maharshi kanak who was provides the theory of atom in their vedas
Bro is confused about quantum physics and trying to confuse the entire youtube with him.
Anyone get 1-2 mins through and realize they don’t really care?
Rewatch the whole thing over and over… you will. it’s worth it.
This explained nothing.
😅😅😅
QM classicalized in 2010. Forgotten Physics website uncovers the hidden variables and constants and the bad math of Wien, Schrodinger, Heisenberg, Einstein, Debroglie,Planck, Bohr etc. So,no.
Well that was interesting 👍🏻
Glad you think so!
The deadpool cameos were epic lmao🤣
Maybe the other dimension that we need in quantum phisics îs the consciousness that îs aware of matter and subatomic particles,our own consciousness
THERE IS MIDDLE GROUND. WHETHER DEAD OR ALIVE, THE CAT STILL EXISTS
You are wrong about even that. So was Schroedinger. :-)
Thank you.great sci fi.
Glad you enjoyed it
How come nobody ever talks about what the monitoring device is? I don’t mean the screen in the background, I mean what is actually used to look at the photons creating this phenomenon.
It's an irreversible energy absorber. This follows trivially from classical physics, we just don't teach very often why and how it does that.
I though I misheard it the 1st time, but he definitely said "Adead or Alive". Lol
So are all the parallel universes sharing the same electrons and we're constantly like flickering with trading electrons with our parallel reality. Like those old flicker films
this turned into analog horror
If quantum mechanics wasn't logical, it would be useless. That's not what Schrodinger's cat was about. Stop misinforming people.
Wait a second I get it now a Deadpool is not actually without motion
Quantum mechanics couldn’t be more different than classical physics. Classical physics is stuck on the wheel while the quantum world is unlimited.
So to sunmarize in simplest of terms: The laws of our world does not work in the quantum world. Particles can exist in seperate states simultaniously, which in Theory could prove the existence of a multiverse? The state of a particle in the quantum world is also affected by observation, Have I got it so far?
No, you got it completely wrong. One couldn't possibly be further from the facts than you are. For starters, there are no particles in quantum mechanics. Quanta are small amounts of energy. We try to teach this in high school, but basically nobody listens.
@@lepidoptera9337 You don’t have to be condescending about it. I’m here trying to learn. You talk about how terrible the school system is which I agree with but then you belittle someone who knows less which is just as bad and also a reason why people don’t learn. Because they don’t wanna ask.
@@hitrapperandartistdababy I am not condescending. It is merely a fact that I am painfully aware of because I didn't listen carefully enough in high school, either. Since I am a physics PhD I had an entire professional life to reflect about the disconnect between what we teach and what we remember. It turns out that a lot of the things we teach at the high school level are far more profound than we think. All of quantum mechanics makes a lot more sense if you can remember these 19 words:
1) Energy is the ability of a system to perform work on another system. (13 words for the definition of energy.)
and
2) Quanta are small amounts of energy. (The most basic definition of "quantum".).
The "strangeness" of quantum mechanics is a direct consequence of the human attempt to identify energy (a system property) with material objects (particles). Even the high school level treatment of the subject allows you to avoid that mistake completely. Properties are different from objects, even in classical systems. In the phrase "red car" we have one property (the color red) and one description of an object (car). Cars and colors don't behave the same. Cars can accelerate, they can change lanes and turn corners, they can even collide. Colors can't do any of that. Colors can mix, though, which cars can't.
So, yeah... language matters a lot for the correct reasoning about reality. That's something that gets lost easily during the teaching of facts.
The following may also sound condescending to you, but it's the key to being a scientist: YOU have to be your own worst critic because nature is never wrong. It is YOU who is almost always wrong. That's a fact that will become ever more obvious the longer you study a scientific subject. So, yeah, if that is emotionally hard on you, then science is not going to give you much joy, I am afraid. It's a life long learning process... and most of what you have to learn is actually the unlearning of your own worst ideas about "how things should be". Only then can you learn to see how things actually are.
@@lepidoptera9337 “One couldn’t possible be further from the facts than you are” Implying my understanding was ‘dumber than average’ on a subject that is notorious for how difficult it can be to understand.
that is indeed a completely unescessary addition to your wording solely written for the intention of showing some kind of superiority and or belittling.
A simple “No, that is incorrect” followed by either an explanation or nothing at all would have sufficed plenty. I’m also sure you are quite aware of that fact. Based on your other responses one would imagine you are annoyed by the lack of knowledge on something you master.
It’s also entirely possible that you aren’t aware of the fact in which case I’m here to tell you your wording comes off as incredibly arrogant and condescending.
Has nothing to do with my “emotional level” (which is also pretty telling of how you view yourself as above others making a comment like that)
its simply about basic common courtesy and respect.
I came to this video seeking some knowledge on Quantum Physics because I find the subject very interesting, my knowledge is completely beginner and I welcome any information and correction. In fact I wrote my comment to ask for responses
Just not when I find it to be belittling or patronizing in tone.
If I where to teach you soccer and you made a poor kick should I also say
“That kick was completely wrong, it could not have been further from proper form” Well it’s certainly the way certain teachers become
“That teacher” No one liked.
@@lepidoptera9337 Science isn’t about smacking people down for being wrong. Has nothing to do with the subject and everything to do with you.
Do a video on why audio levels fluctuate drastically between videos.....
It can happen when they are recorded in different environments with different acoustics.
thank you! i'm more confuse now 😭😭😭😭
oh no, how come?
You’re incorrect about Shrodengers (spelling) cat. He came up with that thought experiment to show how absurd it is to state that the cat is both dead and alive. That’s not how the world works. A cat in a box is either alive or dead. Period. We don’t fully understand the math or the correct way to measure the quantum realm so we can’t describe everything about it.
Yes, we do understand both the math and the physics of this fully. It was Schroedinger who didn't. He wrote an article that was full of confusion and he ruined the subject with his explanation for generations of people who are being deceived by his false reasoning.
Couldn't you think of an even more patronizing title
I can consider myself a pretty smart guy but I simply cannot wrap my head around quantum mechanics. Same difficulty with wrapping my head around the vastness of the universe and light years
They key is the following phrase: "A quantum is a small amount of energy.". Quantum mechanics does NOT describe how objects behave. It describes how energy is transferred between physical systems. Energy is not an object, hence it does not have to behave like an object. Mystery solved. The remainder is some fairly straight forward math.
Quantum physics proves that light is electromagnetic oscillations in the magnetic field.
The magnetic field is not affected by the wall in your example
What scientists are observing is one side of the oscillation on each side.
Half a wavelength at light speed to "change sides" is undetectable by today's methods.
Photon is a measurement (quantity) of energy. Not a particle.
The measurement is not useful and has led to this fallacy that light is a particle.
Quantum physics proves light is an oscillation in the magnetic field
Quantum physics disproves Einstein on many counts. But to be fair other the great people have been disproved on many counts - Sigmund Freud ect!
How does the ability of a particle having multiple possible locations mean that reality could be different?
So as I understood it, (and I literally just watched it myself so I have no idea if I’m right) if a particle can exist in 2 different distinct stages, it would lend credence to the theory that both states of this particle are their own seperate interpetation of reality. We know where the particle should be in a place but at the same time it can be a different place and should be a different place from another alternate reality.
Only thing I’m certain of is that it is merely a theory at this stage.
Maybe this can simplify it: Imagine a quantum car. Since quantum physiqs the car exists both in the parking lot basement and the top floor at the same time, yet you can only see and predict the car to be in the parking lot, therefore an alternate reality of you would see the car on the rooftop.
(Anyone smarter than me please correct me if I missed the mark completely!!! 😅)
Particles don't have different locations. More precisely, particles do not even exist for all we know. Nobody has ever seen one. What we are observing are exchanges of quanta of energy between physical systems, but because "shut up and calculate" works for most users science is not self correcting with regards to teaching the wrong ontology. Most physicists never notice that they have been taught wrong and so they continue teaching wrongly.
Conscious observer collapses the wave and creates one reality or the other. 🤷🏻♂
Tamil explanation video podunga sir
Schrodinger was trying to demonstrate how ridiculous the science of quantum physics was.
Yes, and instead he demonstrated that he didn't understand it.
what do u mean
Lol, so what you're saying is you attempt to teach complicated physical and mathematical concepts, but you don't understand the plot of Avenger's Endgame
Very respectful of you to give a nod to ISRO right towards the end. Well done.
You should state that all you said is theory not knowledge!
I like the Deadpool..
And the BTTF DeLorean...
And the Avengers...
It would not even make the same difference
Nah keep the animations. Its original
nice
Instead of explaining an unproven theory could you try to explain why it contains so many inconsistencies? Or don't you anything about Lorentz Transformations?
Quantum mechanics is not only perfectly consistent with relativity, much of its structure (if not all of it) is caused by relativity.
@@lepidoptera9337 Both are Hollywood style theories and both are still unproven.
Wait till I tell my other self about this bs
I dont understand why everyone always misrepesents the shroedingers cat thing. What about the world from the cats point of view? like it or not the cats point of view is there and it doens entangle with the subatomic realm just like us.
The cat doesn't matter. The point of Schroedinger's cat is to show that there is a non-trivial difference between reversible and irreversible systems. Quantum mechanics expresses that gap perfectly fine, Schroedinger was simply not happy that the gap exists in the first place and it ain't small. It's actually what creates reality.
Mass is occupied areas of space. Cold space is in mass. Mass is in constant maximum velocity momentum propelled through space. Cold resistance is transferring through mass, as mass momentum is in constant forward momentum in resistance. Magnetic fields are created by resistance to forward momentum causing mass to cycle in on itself. The greater the mass the greater resistance to forward momentum. Resistance in mass is in equalization as outward force contained in magnetic fields of forced cycling circulation patterns. Distance is reduced as mass expansion increases resistances to forward momentum. Momentum is constant velocity in entanglement and out of entanglement. Maximum momentum velocity of thermal energy singularity frequencies is a constant value. Frequency is vibrating from avoidance patterns of spiraling through cold resistance that is the fabric of space that is transferring through mass in transitioning areas of occupation time-line. Equalization is maintained in cycling circulation of outward pressure held in magnetic fields of forced flow. Frequencies spiraling rebounding in contained fields of force holding mass together in cycles of maximum momentum velocity of thermal energy singularity frequencies amassed in entanglement.
Does not make any sense. Could you explain in simple english rather than make it so complicated for a layman to understand? The simpler you xan make the bigger expertise you have in the subject rather than going all technical mumbo jumbo.
No jargon please! No long and hard scary-sounding words either! And no complex sentences! Just plain simple English!
Why are the photons so angry?
It saddens me that people will see all these silly movies, and talk like they understand the quantum universe.
People see movies and cartoons, and think they are smart. I've been srudying quanrum physics for a few years now... and it still amazes me! We have no idea of how it works.... but we know it does.
What amazes you about an ensemble theory of energy? It's basically just Kolmogorov's axioms applied to microscopic energy flow.
I still didnt understand nothing
Great ~ ! 💝 💯 👏 🎉 🙏 🚀 👍 🤖 🎅 ✝ 🌝 !

One day, I too will be, “a dead”
switched off at 0:21 with WRONG atom! good luck!
These kinds of topics should not be introduced in schools and colleges as most of the students will fail in their academics.

Cats aren’t in the fundamental world we are in physical world it doesn’t apply it’s just nothin…
Ahhhh, now I get it! 😃
(not really)🙄
Dude the animation and sound is so distracting, I couldn't even finish the video, so annoying
الحمد لله إني وجدت قناتك من بين كل العرب
It’s a very bad idea of explaining something (voice over) and at the same time what we are seeing is different, and even as different text. It’s ridiculous you guys don’t understand the brain can not capture information this way. Sorry, very bad video. It could have been goo doe since the voice over text is not bad.
Thanks a lot for the feedback. This surely helps and we will keep this in mind for our next videos.
i think the animations/visuals are a bit distracting from the information being read out
thanks for your feedback
go back 2 school,
llearn about "position of state"
mood is a factor
Quantum cool 😎
👇if you agree
It's easy, you don't really exist, you're a wave in spacetime. So wanna talk about God yet?
Still don’t understand tbh 🙈
Neither do these guys. They can't teach you what they don't understand themselves.
the animations are very distracting.
Thank you for resisting the type of moronic music track that renders many scientific videos unwatchable.
you have demonstrated you know nothing about QM. you just copy other youtube. this is just click bait.

this doesnt make sense
Hello
can't help but feeling the whole thing was informative but incredibly condescending. this opinion is not effected by my race gender or any other sensitivity.
It was completely false, as well. ;-)
If a tree falls no one’s there does it make a sound??? Of course it does. It’s not not dead or alive in a superposition hahaha 🤣. It’s either dead or alive it’s not a superposition at all. This daft for physics ppl to say it’s equation equations can be solved this is just speculation. Look this cat is either dead or alive because we are physical beings god made is of course it’s alive or dead stop messing around I want real equations
TOO MANY VOICES!

Movies don't have to get it correct. Why? Because they are movies and made for entertainment. They are not documentaries.
They can get more people to watch a movie than they can to watch a documentary.
Why? People want to be entertained not educated.
Its part of the dumbing down of Americans.
Tom Cruise film can earn $1billion dollars full of scenes that would never happen but a documentary an barely earn back its budget if PBS didn't have corporate sponsors to pay a large or all thr expenses of the documentary.
F marvel. Ask Dr. Manhattan
