- A simple and clear explanation of all the important features of quantum physics that you need to know. Check out this video's sponsor brilliant.org/dos
I have spent a lot of time thinking about how best to explain quantum physics and this is the result of all my hours of pondering, and I’m really happy with how it turned out. I decided to just explain it as it actually is, rather than rely on analogies. The video explains the quantum wavefunction, particle-wave duality, the measurement problem, the double-slit experiment, superposition, entanglement, quantum tunnelling, the Heisenberg uncertainty principle, and energy quantisation. Let me know if it was helpful! Cheers Dx

For a more detailed introduction to quantum physics: 'The Quantum Universe' by Brian Cox and Jeff Forshaw is good.
And a slightly more advanced but fantastic description of what we do and don't know about quantum physics is the excellent book 'Beyond Weird' by Philip Ball.

After spending all morning reading different articles and finally getting to grips with the ideas quantum physics puts forward, this video was the perfect way to summarise everything I've learned and put it into objectively understandable terms. Great work, thanks! My brain feels bigger today
Because we didn't get even a tiny bit of it. It's all mathematical abstractions. When you touch a tree in the forest, you're not touching the tree, but a mathematical abstraction.
@@zipsteriYou’re not actually touching anything. The “feeling” of that tree is just the opposite electrical forces of your hand and tree repelling each other
I don't really know why I find myself here, I'm just some random fifteen year old with pretty poor grades who was originally looking for photonics videos, but I must say this was pretty well put together and I actually had some fun with this, I found it pretty easy to keep up with and get what I feel is a decent general understanding of the information displayed. All in all nice video, thank you.

Had a dream I should look up quantum physics, I never really got into science or math. I’m a mainly history guy but I find this video and found it fascinating.
The choices you made in simplifying this are excellent. There seems to be a growing awareness amongst quantum physics teachers that the typical introductory analogies are causing more confusion than anything else.
You've even managed to effortlessly explain the measurement problem in an introduction, in a way that would make anyone nod in agreement.

@@domainofscience I agree but we can adopt better models. Virtual Reality Hypothesis 👌
@@only_your_soul_is_real6104 I'm a big fan of Digital Physics/VR models(& the more purely idealistic the flavor the better imo). But regardless of the flavor, such models at large seem to connect the most dots(by FAR), from BOTH classical physics & QM. & I'd say it is TRUE that the rather simple concept of "rendering" is a MUCH more "sensible"(NOT that it has to be) explanation of the measurement problem than say an infinite # of imaginary universes(but at least they're "physical" or would be if it wasn't so absurd)lol. One perceived "issue" is that without specific mechanisms and/or something else to back that aspect up, it really doesn't say much more than "the Copenhagen" as is. & Ironically(sort of) if true, not being able to say much about the rendering process, is exactly how it would have to be. We need to explore the hell out of such ideas. It's definitely gained(& still is) considerable momentum over the past decade or so. Its like clearly a solid kernel/shell of an actual TOE to fans & simultaneously like an ultimate conspiracy theory to non fans.
@@domainofscience Scientist found a mathematical model that fits the behavior to a very high degree. But they(we) don't really understand how or why it behaves the way it does. Especially in any intuitive way that can be explained by a simple analogy. fair?
@@realcygnus I think I know you from the comment section of a certain big toed physicist named Tom.
I have read several books which attempt to explain quantum mechanics, but until watching this I have never gained a more clear understanding of the concepts. The description of the uncertainty principle I thought was particularly concise and easy to understand. Bravo!
Ouch. The uncertainty principle has nothing to do with quantum mechanics. It's a purely classical fact about linear systems. ;-)

This is really cool! Thank you for posting. Would you kindly make a detailed video on quantum entanglement specifically? It’s such a mind blowing phenomenon! For some reason it leads me to believe that the same happens amongst close individuals.
Incredible animation and general production quality! Very well done!
Well, that confirms it. I'm as dumb as I thought.
At least your not alone.
Eh, no one is stupid unless they believe they are stupid. The rest are ignorant.
Agreed. None of this made sense to me 😭
You're not dumb, it's just that the video isn't that good at explaining quantum physics. It should have stopped around the 5:10 mark and then use the remaining time to make sure the audiences fully grasped just the idea that what we understand to be just these tiny particles might actually be something else entirely. That's already a ton to swallow but the video keeps on going. Seriously, has anyone who never studied QPh actually followed it all the way through?
I've seen it happen many times before: someone who's well familiar with the topic begins an introductory video in a very user-friendly manner but within the matter of minutes he completely loses the notion of teaching the uninitiated. He answers questions the audiences didn't even think to ask ("We don't care if it's called superposition, we don't even understand what the damn phenomenon is supposed to be, I mean, is it like atomic binding or something...?) but doesn't answer those they would in fact pose ("Wait, if the electron can either be here or there, why would we say it might be at two places at the same time? It's clearly just at one!").
The fact that you watched this video shows that you crave intelligence and have a passion for learning. Therefore, you’re not dumb. Dumb are those who think they are intelligent and don’t want to learn anything more than they already know.

Thats precisely ne @ 2am

Bro yess😂
Ye 1am
my guy: she's probably talking to other guys
me:
The movement of the particle (any particle) moves around like a wave. Just like a molecule of H20 moves around in the ocean or lake, like a wave. Taken together, the particles move together in waves. If we stop a particle while it is jumping all around and ask it "where are you now" it gives us an answer we call measurement because we measured EXACTLY where it is this instant. But it keeps moving, so the probability is that it is probably here or there or somewhere at any given moment in time. It's the same with Waldo, in where is Waldo. We can certainly predict Waldo will need to use the restroom. So the probability of catching Waldo in the loo is pretty high, compared to other places.
This video cleared up a lot for me. Ive read over 100 popular physics books and this is what made things most clear for me.
I’ve watched countless hours of quantum Mechanics videos. I mean embarrassing amount of hours and it never sunk in. I actually consider myself to be relatively intelligent but there’s something about the whole the thing that really bothered me. With that being said this video is by far the best explanation I’ve ever seen. A few but very important key things was said that tied things together.

This is without a doubt one of the best explanation of quantum physics on UA-cam.
It should be noted that for tunneling, a "barrier" doesn't necessarily mean a wall. Some people may be thinking of the walls in their house. What it means instead is a potential barrier. In other words, a voltage potential difference, or a different energy state.
Yes, excellent point. I was thinking of explaining this in the video, but it didn't make the cut.
But in microprocessor there in actually a wall . What's your take on that?
@@shrivatsakulkarni9282 That's not how that works. Look up Fermi levels.
Which doesn't differ much from the walls in your house. Isn't it just a bunch of atoms in solid state that would repel anything else approaching with electromagnetic force? How is a potential barrier different? Same interaction type, same force, so a valid analogy.
@@armpap1 No. That is a completely different approach that includes a proton and screening effects. That's not applicable to understanding the basic 1D model of tunneling.
Check out the exchange above. The creator of the video has a PhD in Physics and I'm currently working on my PhD.
Now, we could look at atoms for tunneling INSIDE the atom. But, it has nothing to do with an actual wall.

How do they "observe" which slit the electron goes through? i know its with a measuring device, but what exactly does that entail? is it a stream of photons going past the slit or something and you just measure when there is a break in the stream to determine which slit it went through?
Also how do we send just 1 electron through the double slit experiment, when ever they say that, they always show a laser beam, which i imagine would be many many electrons in a stream, or do they send a pulse or sumut?
I was thinking perhaps, electrons travel as a wave but then collapse to a particle when they touch something, however i found an error in that thinking, because if that were true, the wave should collapse when it touches the double slits.
I would appreciate any input and thanks for the video. Also others feel free to add your input.

Thanks a lot for an engaging way of explaining something I still do not understand, but still find extremely interesting and intriguing:)
I think what Richard meant in his quote was; once you understand it, you need to forget it. What is, isn't always. The rules are constantly changing and evolving. Just like the universe is constantly expanding. It's like finding a cure for a dis-ease (disease). Take for example syphilis. There was no cure for syphilis up until mid 20th century. What I am trying to say is; if you are working to solve something. Then what you are working on is not really impossible. It's more possible than you think.

The Heisenberg uncertainity principle was wonderfully explained!!!
True. I'd always known what the uncertainty was but never had the intuitive understanding of the uncertainty. Great explanation indeed
I knew nothing and now I am a physicist
Very good introduction.
? It wasn't explained at all. Go to 3Blue1Brown for an actual explanation.
Finally a proper explanation! The canonical uncertainty principle is, at its heart, a statement about wave mechanics, not quantum mechanics, and you’ve shown that here.
But then you consider stuff like different spin components and it gets weird!
Yes but doesn't entanglement provide a way to measure one wave and know the properties of the other entangled wave?
Ive always had an interest for quantum mechanics. When I was 13 I started my studies with super complicated lectures. 2 years later im back at it but I’ve found it’s easier when I first have a basic idea of it! So thank you for this

Probably the best explanation of Heisenberg I have seen. Why isn't it taught in terms of Fourier everywhere?
This actually did help demystify it! Most analogies out there make it sound like pure magic, but the analogy of waves from a pebble thrown in water + the insights on how measurements are done and what models are used help understand what quantum physics is actually about

I think, there are two reasons, why quantum mechanics is hard to unterstand:
1. The underlying math is quite complicated. For the basic concepts of classical mechanics like velocity and acceleration you only need basic calculus, with is taught at school. But the fundamentals of quantum physics involves much more math, like complex analysis and Hilbert spaces. In order to understand something like the Heisenberg uncertainty principle from the mathematical point of view, you must be at least be familiar with the Fourier transformation.
2. Quantum mechanics is counterintuitive. The concepts of classical mechanics are closely linked to our everyday experience. The orbital motion of the moon around the earth and the trajectory of an arrow are two aspects of the same thing. But in quantum mechanics we have to abandon intuitive classical concepts like the trajectory and have to replace them with abstract mathematical things like the wave function. Quantum mechanics questions our concept of reality. Physical quantities can be in a state of superposition, so that they are strictly speaking undefined before the measurement. By measuring this physical quantitity, the state of the system is irreversibly changed, simply because of the presence of this information. But without an idea what really going on at a measurement, it is difficult to get an intuitive understanding how quantum mechanics works.
The solution, perhaps, is to approach quantum mechanics from a completely different angle than described in most textbooks. Instead of a particle in a potential well, one can consider an even simpler system: the qubit. A single qubit can illustrate the concept of superposition. With two qubits you get already entanglement. By learning how quantum computers work one can get an understanding about quantum mechanics even without advanced math. So, the real benefit of quantum computers could be that we use them to better understand quantum mechanics.
I sometimes find myself wondering what math is more difficult, that of theory of Relativity or that of quantum mechanics. I usually end up concluding the latter is more complicated... for differential geometry is all about geometry!
You seem like you now where you are talking about. Which books would you recommend for a rigorous foundation of quantum. I wanted to try landau and lifshitz 3 volume after have a good basis of GR. Do you have other suggestions?
@@David-km2ie I own a copy of the Landau-Lifshitz myself and know from experience that learning from this book can be very hard. He explains many things without explicit mathematical calculation, so that much is left to the reader and you have to actively participate. But if you have worked through the entire book, then you probably have mastered quantum mechanics. (But I can only guess, because I never finished it.) If this is not your preferred learning method, then there are alternatives, such as the Cohen-Tannoudji, which I think is a bit more pedagogical.
@@User-jr7vf It depends how serious you want get into the theory. In principal, even good old Newtonian mechanics gets complicated if it comes to non-linear systems. However, the fundamentals of classical mechanics and special relativity can be illustrated quite nicely without math by thought experiment. But these thought experiments relies on our common sense and our intuition, which fails at unterstanding quantum mechanics. It think, since we are left in the quantum world without the guidance by our intuition, the math appears much more complicated.
I'm not sure I'm familiar enough with qubit for it to help me understand better, but thanks anyway for the tip, I'll try and find more info on the qubit.
i’m only 14 but honestly i want to know more. like it’s so interesting to me. my brain hurt bc i watched like 5 other videos today but it’s so worth it. it genuinely makes me want to study this type of stuff in college.
If it interests you never let anyone tell you that you shouldn't be studying it!
I wish I was interested in this stuff when I was your age, I regret going through school just barely scraping by, studying only enough so I get a pass and then forgeting most of it, and the world is so interesting, sigh... Thinking back on school, there is not one subject that is inherently boring.
I'm 22 btw I'm not old or anything I just feel like there is a lot of catching up I have to do
Me too lol
Good on you. don't give up, challenge yourself, and you will go far in life, great to see women taking an interest in science, I'm still freaked out by the twin slit experiment, how do the atoms know we are watching them??
Thank you so much! All I could find on the internet was really complicated shtick, as a person without good maths or physics education all the numbers and unexplained variables quickly threw me off - but this helped! In a very concise way even.
Quite understandable synthesis of quantum physics for almost laymen like me who try to understand it a little better. Thanks for the simplification
That was a great way of explaining the Heisenberg uncertainty principle utilizing the addition of sine waves / fourier transformation.

Yes! Just a drop of water in an endless sea.
All we do crumbles to the ground,
Though we refuse to see. 😁
We are spirit and soul too!!
I think that when you get down to quantum, you are dealing with another dimension of our universe. we can sense and experience 3+1 (3 dimensions plus time dimension, and they think the universe is 10 or 11 dimensions), which explains things like entanglement over long distances.
Thanks to your video, I could understand it. I'm in 12th grade and our books don't have any explanation for Uncertainty Principle or the Schrodinger equation. They just have given the equation and stated it. Also, my chem sir had given a very bad analogy of the Uncertainty Principle ("You're sitting right now, so you have fixed position, but no momentum" . He even said it's easy..) , it's embarrassing tbh. So I would have got frustrated by analogies as such. You were on point. YT is definitely best place to learn. Thanks to youtubers like you.
This video actually does a decent job of representing this.
I’ve just watched this with my 8 year old who has been asking me lots of questions about quantum physics having watched Antman. A bit technical for him just yet, but I learned something! Thanks!
Tanx alot for the video
The wave-particle part is the same for the electromagnetic spectrum as for example: X-rays travel in wavelenghs but interact with matter as particles.
