Hi everyone, thanks for checking out this video! :) Please let me know if you have any questions or suggestions. I'm still cooking up parts 2 and 3, so I'm hoping to modify those based on your feedback. Edit: lots of great responses so far, thanks everyone! A few of you pointed out that the transitions between 100, 200, and 210 are more complicated than I’ve shown here, and you’re totally right, when thinking about angular momentum and such there’s more nuance involved than just shooting any old photon at the atom. We’ll talk more about that in the next video :)

Here is a question. Why you don't have thousands likes and more? I really cant understand...

I love that real reason you switched to mu is because you want to use "m" later to mean something else! Honesty/self-awareness is the soul of analysis. Keep it up. Some days the biggest frustration of mathematics is running out of, and keeping track of symbols.

Just a couple of points about your video, since you asked for suggestions: (1) The 1s to 2s transition is a forbidden transition, so it requires two photons to have it work, not one as you illustrate (1s to 2p is fine and 2p lives in the excited state about a billion times less long). This plays an important role in the Lamb shift experiment and in the proton charge radius experiment. (2) You seem to be using an ontic viewpoint of the wavefunctions, as if the electron is the wavefunction. Some people do use this picture, but it can have a lot of issues with interpretations of quantum phenomena. It might be useful to explain these issues. (3) I am not sure if this is your first discussion of kinetic energy as a Laplacian, but because for waves on a string, the second spatial derivative is the potential energy, some additional discussion of why it changes for quantum mechanics might be helpful to your audience.

This is perfection. After having finished my first quantum course (working up to the hydrogen atom), I found some of the later material as explained in the Griffith’s book to not be so intuitive (especially on 3D wave functions). So this is a really nice bridge between intuitive clarity and rigor, as others have mentioned. Thank you for the awesome content!

Really glad I found your channel, love to hear the enthusiasm in your voice! I feel the same way about physics, very late to the show, but I'm kind of hooked now. There's always a little Eureka moment when I try to extrapolate on what I'm learning and then have it confirmed or fail, which leads to more learning. Something very Promethean about it, music synthesis really gave me a lot of insight into wave forms, helps visualize the math and make it fractionally less daunting!

"let's solve it for PSY, how hard can it be?" - To be continued Perfect cut x) Good video thx

This video is fire! I think it's one of the best resources out there for learning and understanding quantum physics. In my opinion, there are three main aspects to learning: knowledge, understanding, and motivation. We know that 2 + 2 is four, but unless we understand how addition works, we won't be able to solve 2 + 2 + 2 on our own. And without motivation, learning becomes challenging. I particularly enjoyed the beginning of this video. The excellent animation made me contemplate how atoms truly behave and why. It sparked my curiosity and motivated me to learn more. Your video has fantastic visuals that help us grasp the concepts, and your explanations are well-timed, clarifying everything effectively. I liked everything about this video, but I do feel that its length wasn't sufficient. However, it's great that you made it that long, as it doesn't intimidate viewers. It also provides breaks and leaves us eagerly anticipating part two. What I would suggest is creating separate videos. I would love to learn more about how quantum physics developed since it's complete beginning. How did Schrödinger derive his equation? Why do we use Hamiltonians? It would be wonderful to see examples of their use. For instance, pose a simple question and provide a solution using the Hamiltonian.

Great introduction. Looking forward to watching following videos. I'd like to share one tiny observation I made (only recently) about spherical coordinates that no-one seems to mention, but when you see it, it's one of those 'how could I have missed this?' moments. And that's that phi essentially looks just like a circle with a line of longitude drawn through it, and theta looks like a circle with a line of latitude drawn through it. This must have been why these Greek symbols were originally chosen, but I've never seen this easy aide-memoire written down anywhere.

@RichBehiel

Thanks! :) Yeah I’ve wondered that too actually, hard to imagine those letters were picked coincidentally, but no one ever talks about it.

I don't usually write youtube comments, but this is one that I truly feel I owe to you, the creator of some of the most comprehensive and thought provoking study videos in the physics side of KZread that I've personally come across. Another reason I don't comment much is because I'm a serious yapper, which I assume anyone who reads this will soon find out, and I doubt anyone has the time or interest to read what will inevitably be at least two or three paragraphs of melodramatic nonsense. If you'd like to skip the context, the last paragraph is really the only one I hope for you to see and recognize. I'm a 26 year old who always had a passion in physics, but grew up constantly telling myself that I'm not cut out to understanding these things. That would mostly stop me from even persuing that passion into something greater. Every now and then, though, I would be inspired. I would be so inspired that nothing else in the world would matter to me. There were times my life would literally be falling apart around me {a bit of an exaggeration, but it's better for the story} and even still, I could only think about solving the problem which inspired me, and that's where all of my energy would go until I was able to come back to some sort of normalcy. I've never gone to school, so I don't have any formal education of anything beyond AP Highschool. This has made it difficult for me to accept my interest in this subject due to some sort of asinine supuriority complex I was projecting onto myself. For a long time, I didn't even think I had a right to be interested in learning something as deep as Harmonic Oscillators, the Schrodinger equation, or other principles/equations that could go as far as being the necessary tools to begin explaining the abstract nature of the vacuum and how it acts as some sort 'medium' (Not aether, although I'm not going to completely rule it out until I can understand the math that tells us it's impossibility) to bring Bosons and Fermions together to form what we know as matter. Or, at least, that's at the core of the question I'm currently trying to disprove for myself. Whether or not I'm successful is inconsequential, as the further I delve into these equations, the closer I come to understanding the nature of the universe. Although, it sometimes feels like every answer puts me 10 steps backward, lol. I'm still a complete novice, but I've accepted the fact that my mind is curious and creative enough to think more deeply about these notions, even if it is currently misguided due to an inexperience with the language that the math forms around physics. I've been subscribed to 3Blue1Brown for years now. I found your channel after watching his Essence of Linear Algebra series, and I have to say, it is likely one of the greatest channels I've come across. You go into the detail. You present it in a way that is entertaining. You show visualizations to help with making the equations more intuitive for those of us who aren't familiar with the mathematics of it all, yet. I haven't actually visited your channel yet, but even the first 5 videos I've watched from you has filled at least 10 pages of my journal with notes either from your direct lectures, or from the subsequent research that your lecture spun me into. Last night it was the harmonic oscillator, which I then spent 4 hours researching and studying. Today.... It will likely be the same because there's a lot that goes into that. The point is, though, that I hope you are able to recognize the inspiration your videos provide to others, and that you are genuinely the 3Blue1Brown of physics youtube. I don't like comparing people to each other, especially in this manner, but I mean that in the most complimentary way possible. You're amazing at what you do with these, and I sincerely hope that you keep making this content. Or, at the very least, that you walk away knowing that you made a hugely positive impact on at least one person's journey through this never ending whirlpool of theory and calculations. I've only just begun watching your videos, and I can already say that you've made that impact on at least me. Cheers 🍻

Thanks, glad you enjoyed the video! :) Declination angle actually already has a definition in astronomy, which is closely related to the theta angle here, but I believe it starts at 0 at the equator and then has positive and negative values. The theta we’re using in this video is formally called the colatitude angle, but people often call it the polar angle or, or speaking casually someone might say elevation angle or latitude or inclination. In the context of distinguishing between the angle that goes up and down, vs the angle that goes around, any of those words are ok, I think. The most important thing is defining what the degrees are and which way the coordinate goes, for example theta = 0 is the North Pole and 180 is the South Pole.

I think this is the correct way to teach those you really have to move at kind of a clip, because if you slow down, people will get bogged down in the weird notation and all the symbols and things which are very easy to understand if you just look at the whole picture quickly and then let your brain figure it out, but every difficult if you let your brain get really granular. My professor opens this topic with teaching Dirac notation at the same time so obviously it didn't go super well.

From the classical world the leap to the quantum world is like a transition from physics to metaphysics, when the act of observation measures its effect on the whole world. Like the imaginary number i can express orthogonality and also permit factorization of all polynomial as real numbers are replaced by complex numbers forming a field, stretched on all sides to infinity. This change from physics to metaphysics enables us to enact QC functions, conjectured by Maldacena to encompass the whole universe and all processes in it, as the universal complexity gives rise to life, consciousness, soul and faith.

This video has exactly what I was looking for. Thank you.

Really love this Richard! I barely understand anything here, but I want to go deeper and grasp it properly. Keep doing this, I hope to see the other two parts in the serries! The presentation and the way you explain this is captivating and very easy to follow, that is before all the math creeps in and starts crowding the place. If I would ask a quiestion, it would be when you define the wave function ... is it a quaternion? Is this why it belongs to the complex numbers? Or is the time component considered an imaginary part? Does it evolve back in time? Or is it that the spherical coordinate components are each imaginary numbers like in a quaternion (like i, j, k)? I see in previous slide (@5.35) there is a complex phase, but a phase supposes two waves that need to be in or out of phase by a certain time maybe? So I guess the time is the Complex value in the wave function then? If you could expand on this, it would be great!

There is a relationship between time and phase in quantum mechanics, for example the phase of an eigenstate will oscillate with angular frequency E/hbar.

To clarify that, it's harmonic oscillator-like because the electric potential term is attractive and the the kinetic energy term (the gradient or divergence of psi, the Laplacian) acts like it's repulsive, and that bounds the electron position into the geometry of those energy states?

@@cademosley4886 yeah exactly, there’s that balance of energies, electrostatic pulling in and kinetic energy pushing out when the electron gets too close, with various equilibrium states occurring when things are balanced. So it’s sort of like a 3D cousin of the harmonic oscillator. The hydrogen energy eigenstates can then be thought of as resonant modes, sort of the ways in which a 3D quantum springy thing can vibrate. That’s just a loose metaphor of course, but it’s how I imagine it at least.

@@RichBehiel I think it's more than a metaphor because you can consider the effective potential from the electrostatic + the radial contribution from the Laplacian.

It’s funny, 31k is already beyond my wildest expectations 😅 The response to these videos has been so wonderful, not just in terms of numbers but just the positivity and good vibes coming from everyone. I feel very fortunate to be able to talk to people who are also passionate about physics.

I’m looking forward to parts 2 & 3.

you are the first one dealing with quantum mechanics i didnt pause the video

I really like this format and the way you explain the maths. Which I urgently need to make my semi-schizo rants slightly more coherent. You actually read them, which is surprising. I wonder how many university physics departments' blocklists my email address is on by now... On this subject of QM, I'd love to one day to see some tie-in or expansion on the Mach-Zehnder interferometer. I learned of this in the MIT OpenCourseware on QM I watched a couple of years ago. I think it demonstrates "quantum reality" more interestingly than double-slit experiment and really puts the universal causality "missing link" into perspective. I also wonder about phase conjugation in nonlinear optics and this "distortion correction" principle and what the math there looks like with respect to time (wavefront / time reversal). How that relates back to what this interferometer shows. Really, I'd love to have more understanding of optical phase conjugation all around. Just throwing some ideas out there. Thank you for this content! It's very inspiring.

Thanks for your kind comment! :) Yeah, there’s a lot of cool stuff that can be done with Mach-Zehnder interferometers. If I remember correctly, there are quantum counterfactual experiments that seem pretty interesting, but honestly I haven’t really looked into them. Could definitely be an interesting topic for a future video though.

This was done really well!!! Thank you 🙏🏼
