I love your videos. The combination of history, technical details, and elaboration are so engaging and enjoyable. Thank you very much for making these.
In my opinion, this by far the best theoretical video on the subject I've seen so far. I've even watched it multiple times! The actual math is going at an extremely high speed, which is I guess okay, because otherwise this would be a very long video. I think though that on a detail level it will be difficult to follow along for many viewers. But I very much appreciate the general overview that it also contains: how the fluctuations in energy in a confined system holding electromagnetic radiation can be described as a combination of wave and quantized properties, whose relative importance is dependent on the frequencies contained in that system. In a way that aligns quite well with my own view that a photon is merely a quantized interaction between radiation and matter (or vice versa). If you think about how energy fluctuations can come about in a system , it's only because of energy interaction / exchange with the external system. Depending on the nature of the interaction and wavelength, the interaction will bring out the wave- or quantum nature of radiation. The reason that I personally consider the photon to be an interaction is that it allows me to easily make sense of interference and diffraction experiments with light. Anyway, your videos are top notch, so please keep making them!
8:58 That is so gorgeous. The main feature that determines how quantum objects behave is their wavelength. Low wavelength, high frequency objects behave like particles, so high energy photons such as gamma rays participate in processes such as Compton scattering which is basically an elastic collision between billiard balls. Whereas large wavelength, low frequency objects behave like waves because we can measure their wavelike properties more easily (since obviously their wavelength is larger). This corresponds to things such as electrons in energy eigenstates of the atom, or low energy infrared photon absorbance causing molecules to oscillate with the wave. That the low frequency and high frequency fluctuations are given exactly by the number of wave modes and quanta respectfully is an *exact* illustration of this duality. As always, your videos are as informative as they are entertaining. Keep it up!
2 very pretty equations today. What is the meaning of the first one- variance of energy = partial derivative of average energy wrt beta. Is that not a form of entropy?
"True, nobody accepted his idea, but his physical reasoning and calculations were flawless" How to impress the scientific community through sheer balls
That is how you defend an idea: provide solid physical and mathematical foundations so nobody can ignore it, then drop the mic and move on to develop a new theory of gravitation (General Relativity).
@@jkzero it used to be like that. Today you need approval of the community to even try posting on arxiv, or be part of an institution to even be considered for peer-review in a journal.

Just saying 'pure quality of reason' is no longer enough because it won't even get noticed
Woah, that's an interesting analogy on wave-particle duality of life. I've always assumed before that it's both a wave and a particle, but somewhere I learned that it's not a wave, it's not a particle, but it's also not both. That cellphone analogy makes it a bit easier to digest now.

The fact that 1/M and 1/N are added instead of multiplied indicates their relationship. Two sides of a square are multiplied to get the area, but two squared sides are added to get the square of the hypotenuse. So the question is what does the hypotenuse of 1/M + 1/N represent? Figure that out and you figure out how the object is producing both. My hypothesis is: the field itself or time. Or to put it another way: √(1/M + 1/N). This simplifies to √(N+M/M•N), which is √(/) = Eᵥ (Volume of Energy). Since E simplifies to bare time³, then Eᵥ = 𝘵³, which is to say, the velocity of time, generating a 3×3 temporal matrix field. At its center is a particle, and its boundary produces the wave. As the wave (boundary) expands, its mass increases. This effect increases when the field interacts with other fields. So while the wave does no work, the field works to give mass and the density of the field causes repulsion. The field is not a background, but a mathematical bubble relative to other similar fields.
Excellent video, as always! I'm really excited for the next videos on the De Broglie postulates and other developments in the history of Quantum Mechanics
incredibly unsubtle hint that QFT might be a topic later... very awesome thank u for these videos they are genuinely works of art, I like how u don't shy away from the math it feels less like you've plucked ideas out of thin air and makes them feel more like the rigorous ideas based in what was known at the time
I like to present ideas and developments that at less known but always providing the sources to the originals so anybody can go and check by themselves, there is no need to believe me, the math is there, which is the best way to support wild claims
Oh yeah, people celebrated his papers on Brownian motion and special relativity, but ignored him completely on his paper of light quanta (the one incorrectly called "photoelectric-effect paper"). If you watch my video about Compton effect (ruclips.net/video/Ap9os356CZA/видео.html), which completely confirmed Einstein's hypothesis on light quanta, you can see several instances in which people like Planck celebrated and supported Einstein although they considered his light-quanta to be nonsense. Even Bohr during his Nobel lecture in 1922 insisted that light quanta were not a real thing.
Absolutely wonderful video! Thanks for going further into the history and math of the light wave-particle duality! The De Broglie teaser surely sounds nice!
Amazing video! I can't believe how beautifully you've tied everything together. Even those little side mentions of Bose's new method and Uncertainty principle hiding in plain sight, I wanted you to go deeper into! So fascinating
Still haven't finished the video yet but it is interesting to see that it's denoted as . I am taking a (rather) introductory course on Statistics right now and we use E bar for denoting the expected value in the moment. That said, our E is expected value and not energy so it might be different. Still, Einstein did denote it as E bar in 4:25, so.
I think the bar is most commonly used by mathematicians; physicists used it until modern quantum mechanics appeared (mid-1920s) because the bar over a symbol can lead to misunderstandings when it is used for complex conjugation or spinor notation. The notation avoids that problem and it directly matches its use when Dirac notation gets introduced later.
Dr, I simply love your videos. With the addition of mathematics, it me realise how these scientists arrived to their discoveries and conclusions, even though the math is beyond my scope. However, your narration when u present the equations and how u manipulate them to arrive to the result, makes it Simpler for a person like me to follow along. Thank you for hard work you put in, making these high quality, well researched complex topics for us.

I just realized that I have been answering the question wrong. “Is light a particle or a wave?” I’d usually answer yes. Now I am understanding it’s neither but it’s a quantum object that exhibits properties of both. 20:03 The de Broglie teaser demands I keep coming back!!!

I am with you here, love the fact that Jordan just added this at the end of the paper as extra material but it completely started a new field and a new way of doing fundamental physics
3:33 How did Einstein come up with the idea to determine this derivative (the change of the average energy by the change of β (1/kT))? What was his physical motivation for this?
There is no physical motivation, it is a standard trick in statistical mechanics, in which there is a function called the "partition function" that can be used to generate many thermodynamical quantities by taking derivatives. Using this approach, taking the derivative of the average energy in reality is hiding a derivative of the partition function. In other words, after you take any introductory course on statistical mechanics and this is almost a natural to do.
Following you the whole series. Excellent videos, as well as aspiring, I have always wanted to see the matrix mechanics in QM but haven't come by; it would be great if you could make a video on it. And can you tell me where you are finding these original papers?
An intro to the first breakthrough by Heisenberg and the follow-up matrix mechanics will come soon. All of Einstein's papers can be found in the link below; however, I don't include the translations in my videos because they are copyrighted einsteinpapers.press.princeton.edu/
Excellent video! This channel is the best. It explains thing without dumbing it down. I love the historical references, and how you explain how these things developed and how the interactions between the scientist were at the time. I would love a video on matrix mechanics too. Also: I read that something called SeaStar algebra represents a potentially deeper and more fundamental approach to quantum mechanics than the Hilbert space formalism. Do you know anything about this, and perhaps also how it can solve the measurement problem of quantum mechanics?
An intro to the first breakthrough by Heisenberg and the follow-up matrix mechanics will come soon. I am not sure about SeaStar, maybe you mean C*-algebras, which is a set of mathematical conditions used for some types of Hilbert spaces, very relevant in quantum mechanics. There are also objects called c-numbers used by Dirac in the early days of quantum mechanics.
@@jkzero Seems like I misunderstood. I knew about the C* algebra, but I was under the impression SeaStar was something more than C*, but probably just because I did not investigate what I heard on a physics podcast enough. Thanks!

Hmmm wouldn't the energy fluctuation formula show the distinction between wave and particle nature of light since M and N are accounted for separately? How far can the values of M and N be from each other?
Your content could be a really good basis for a semester-long elective for non-physics, technical majors with an interest in physics and history. Call it Classical to Quantum: The History and Development of Modern Physics, with the lectures being akin to your videos showing the historical context for each development, the course work being working through the mathematics to arrive at the results, and a final project of choosing and writing a paper/video demonstration of the development of some result in their major field. I think it could offer a unique way to develop scientific communication skills. I would've jumped at it as a young engineering student 😁 The majority of educational resources I've interacted with (articles, lecture series, videos, etc) seem to be written for either an expert in that field or a layman without a scientific background. Neither is bad, but they both require a lot of additional reading to understand fully (either for context in the former or more detail in the latter). Your videos fall perfectly in the middle, a splendid balance of history and mathematics, where I rarely feel other texts are a prerequisite for a full understanding of the topic presented. Apologies for the long comment. Keep up the great work! I always look forward to your videos
I appreciate the long comment. You got me, what you see as video episodes here are my dream course to teach. I am sure that many STEM students would love to have such an introduction to modern physics filling the gap between superficial presentations and systematic courses on the relevant topics. I even think that this should be mandatory for physics students. I was one many years ago but I was never taught most of the stories that I have presented here. Many physics students and professional physicists have written to me because they had no idea about many of the stories and calculations presented here. So yes, thanks for the encouragement, it is one of my goals turn my notes into a course and/or a book one day.

I love the way that most fundamental physics is explained through an historical perspective on the derivation of matters and equations... Including the historical discussions and motivations.. It's very useful to understand where all this quantum physics come from. Today I just had a huge surprise to see that again a quantum concept comes from statistical mechanics...and I was thrilled to see how the seed to QFT appears already in a 1925 book by Jordan et al. Wonderful. Wooah!!!
The problem with the historical path to quantum physics is that it's false. They guessed the final result correctly, but most of the concepts that were used along the way are 100% false, so you are basically learning all the wrong lessons and none of the correct ones. The idea that quantum mechanics comes from statistical mechanics is certainly false. Quantum mechanics is a non-commutative solution of Kolmogorov's axioms, but it is NOT a slightly different version of statistical mechanics. The latter requires contact between thermal baths, while quantum mechanics requires complete isolation.
Thank you Doc for your vids, I binge watched all of them after last Tuesday and they have been very helpful to my sanity. Seeing this one come up on my recommendations was joyous.
I loved the iPhone analogy. In a similar fashion, the measurement procedure forces the quantum system to give you a result that you know how to interpret, but this measurement only gives us one aspect of the true nature of a quantum system.
Thank you for this video. Somehow I never heard of this derivation, and now I really want to sit and profoundly think about what this means. Thank you again for showing me something Idid not know about. And of course, as always, you do this with an incredible video and explanation
It is really amazing and well done video, chapeau. So let me interfer with you as a wave and as an old-school physist, the Planck formula of a 'dark' body radiation (it is a very shiny object in IR range!) is derived under equilibrium conditions between light as waves and matter as quanta. therefore it is quite logic to have both nature appear in Planck formula. In contrast to open systems or out of equilibrium systems (more general optical systems), such as laser systems. In such systems the Planck formula is not a valid approach either for lasers nor for interference nor for diffraction phenomena! Hope that would to clarify a little bit more the duality principle. the mystery of duality is still ongoing! Dr MANI
Btw, on Einstein's assertion that light itself is quantized into photons (instead of quantization being a mathematical trick), I've seen sources that present the idea that instead of light being composed of flying photon "dots" while in travel, photons are actually _events_ occurring at the detector. The quantization ultimately manifests when *light and matter interact* . Notable sources are videos from the channel Huygens Optics: ruclips.net/video/NVqT2Gbrvxs/видео.htmlfeature=shared ruclips.net/video/5V8VCFkAd0A/видео.htmlfeature=shared ruclips.net/video/gijtzP8iVzs/видео.htmlfeature=shared ruclips.net/video/SDtAh9IwG-I/видео.htmlfeature=shared Any thoughts on this?
Interesting that you mention this work, I had originally included the first hints to the 1916-1917 papers on radiation by Einstein but then I had to remove this part because it took the story in a tangent. But yes, I will make sure to come back to this work in the near future.

I didn't quite understand why it would be more particle like at high frequencies (or low wavelengths) and wave like at low frequencies? Isn't the electromagnetic spectrum continuous and therefore all any frequency is lower or higher relative to any reference point? Or is it all in reference to the planck length? Can someone explain?

It has to do with the quantum system the photon is interacting with. In The metal, there are discrete energy levels deriving from the structure of the material, therefore to extract an electron I need to give it at least the amount of energy that separates it from the potential of the vacuum of the other side of the metal/vacuum interface. This quantity is a constant dependent on the properties of the metal and is known as its "work function". A free electron is different, it can take on any energy level, so when a photon interacts with it the energy can be distributed between the two in a continuum of states. However, they also need to obey momentum conservation, which is why the electrons taking part in compton scattering are not actually free, but bound to nuclei with which they can exchange the excess momentum needed to obey energy and momentum conservation at the same time. The electron can still be thought as approximately free because the energy of the incoming photon is high, so that the discrete gap bounding it to the nucleus is negligible compared to it. So it actually all depends on the energy of the incoming photon: if it is very high compared to the electron's binding energy, then you can have Compton scattering, if it isn't, you won't
@@raffaeledivora9517 That was a beautiful explanation. Thank you very much for that. So if I understand correctly, the photon is not an indivisible packet of energy, and the actual "quantumness" is exclusively a property of the electron who's ability to absorb light energy and convert it into kinetic energy is dependent on its state. Well, that just makes everything make sense. Thank you again.

I disagree with the analogy at the end of the video. When describing the light wave-particle duality theory, we are dealing with unknown unknowns and abstracted away from the reality by layers of calculations with some foundational assumptions. In the case of the gameboy and Walkman, we can clearly define the terms and its is not at all surprising that one device could have both functionality.
Sonwhere is the math that shows N is not just a counting of wavemodes related to emissions from the material of the cavity, aka how many quantas worth of wave energy is in there? I don't see a duality just an accountant counting energy.
So does this mean quantum objects like photons and electrons are neither a wave nor a particle but a new entity call a wave packet that has a dual characteristics?

More than a wave packet, the more correct term is "fields;" photons and electrons are excitations of the corresponding photon field and electron field.
Another duality, of “at least 2”, shows up with lossless sampling: en.m.wikipedia.org/wiki/Nyquist%E2%80%93Shannon_sampling_theorem Now imagine breaking that barrier.
It is very confusing calling a massless quantity for a particle independently which other properties it exhibits as the masses are so central and to be honest, not explained at all until today. Light quanta is a good name for photons.
Mass is effective mass. It's just an effective dispersion relation, not a fundamental quantity. There is ontologically no difference between massive and massless field quanta. They are all combinations of energy, momentum, angular momentum and charges. The only difference is the relationship between energy and momentum.
I tend to think of light in terms of impulse and resonance. The wave nature is an artifact of the mathematics. Particle nature is a prior in the mathematics and is an error. The question is what is continuity in physics AND this goes back to Zeno and is still unresolved.

Also, the usual portrait of a "quantum hater" as shown in popular books is totally wrong, the guy was pro-quantum when Niels Bohr was still an undergraduate student playing football.
I love your videos. The combination of history, technical details, and elaboration are so engaging and enjoyable. Thank you very much for making these.
Thank you very much!
In my opinion, this by far the best theoretical video on the subject I've seen so far. I've even watched it multiple times! The actual math is going at an extremely high speed, which is I guess okay, because otherwise this would be a very long video. I think though that on a detail level it will be difficult to follow along for many viewers. But I very much appreciate the general overview that it also contains: how the fluctuations in energy in a confined system holding electromagnetic radiation can be described as a combination of wave and quantized properties, whose relative importance is dependent on the frequencies contained in that system. In a way that aligns quite well with my own view that a photon is merely a quantized interaction between radiation and matter (or vice versa). If you think about how energy fluctuations can come about in a system , it's only because of energy interaction / exchange with the external system. Depending on the nature of the interaction and wavelength, the interaction will bring out the wave- or quantum nature of radiation. The reason that I personally consider the photon to be an interaction is that it allows me to easily make sense of interference and diffraction experiments with light. Anyway, your videos are top notch, so please keep making them!
Dr. Diaz, the math and your smartphone analogy make the wave particle duality of light simple in a way my professors never did. Outstanding.
Thanks, I came up with this silly analogy long ago and I wasn't sure if I should include it, so I am glad that you found it useful
8:58 That is so gorgeous. The main feature that determines how quantum objects behave is their wavelength. Low wavelength, high frequency objects behave like particles, so high energy photons such as gamma rays participate in processes such as Compton scattering which is basically an elastic collision between billiard balls.
Whereas large wavelength, low frequency objects behave like waves because we can measure their wavelike properties more easily (since obviously their wavelength is larger). This corresponds to things such as electrons in energy eigenstates of the atom, or low energy infrared photon absorbance causing molecules to oscillate with the wave.
That the low frequency and high frequency fluctuations are given exactly by the number of wave modes and quanta respectfully is an *exact* illustration of this duality.
As always, your videos are as informative as they are entertaining. Keep it up!
Thanks!
Thanks so much for your generous support.
one of the best video series on youtube. I eagerly await each new episode
Excellent, thanks for watching. I am having a blast presenting all this content that it is usually left out in QM lectures and textbooks
2 very pretty equations today. What is the meaning of the first one- variance of energy = partial derivative of average energy wrt beta. Is that not a form of entropy?
Thanks so much for your continuous support.
It's amzing that general result is exact sum of particle and wave limits
This result is such a beauty

That is how you defend an idea: provide solid physical and mathematical foundations so nobody can ignore it, then drop the mic and move on to develop a new theory of gravitation (General Relativity).
@@jkzero it used to be like that. Today you need approval of the community to even try posting on arxiv, or be part of an institution to even be considered for peer-review in a journal.
I'm don't wish to defend unsound reasoning without solid mathematical ground that plagues the work of many outside spammers. Just saying 'pure quality of reason' is no longer enough because it won't even get noticed
That the relative energy fluctuation works out to 1/M+1/N is kind of cool.
I find that result quite awesome
Fascinating video. I had never heard about Einstein's calculation of the energy fluctuations, super clear exposition of this
I am pretty sure that even many physicists don't know about this
Very nice video, and I think you make the central point about duality very well.
Thanks, glad you liked it
Woah, that's an interesting analogy on wave-particle duality of life. I've always assumed before that it's both a wave and a particle, but somewhere I learned that it's not a wave, it's not a particle, but it's also not both. That cellphone analogy makes it a bit easier to digest now.

The fact that 1/M and 1/N are added instead of multiplied indicates their relationship. Two sides of a square are multiplied to get the area, but two squared sides are added to get the square of the hypotenuse.
So the question is what does the hypotenuse of 1/M + 1/N represent? Figure that out and you figure out how the object is producing both.
My hypothesis is: the field itself or time. Or to put it another way: √(1/M + 1/N). This simplifies to √(N+M/M•N), which is √(/) = Eᵥ (Volume of Energy).
Since E simplifies to bare time³, then Eᵥ = 𝘵³, which is to say, the velocity of time, generating a 3×3 temporal matrix field. At its center is a particle, and its boundary produces the wave.
As the wave (boundary) expands, its mass increases. This effect increases when the field interacts with other fields. So while the wave does no work, the field works to give mass and the density of the field causes repulsion.
The field is not a background, but a mathematical bubble relative to other similar fields.
Excellent video, as always! I'm really excited for the next videos on the De Broglie postulates and other developments in the history of Quantum Mechanics
An intro to first breakthrough by Heisenberg and the follow-up matrix mechanics will come soon.
incredibly unsubtle hint that QFT might be a topic later... very awesome thank u for these videos they are genuinely works of art, I like how u don't shy away from the math it feels less like you've plucked ideas out of thin air and makes them feel more like the rigorous ideas based in what was known at the time
I like to present ideas and developments that at less known but always providing the sources to the originals so anybody can go and check by themselves, there is no need to believe me, the math is there, which is the best way to support wild claims
Great job on a really challenging topic!
I did not know that Einsteins works of 1905 were not recognized for a long time. Intresting!
Thank you for the video.
Oh yeah, people celebrated his papers on Brownian motion and special relativity, but ignored him completely on his paper of light quanta (the one incorrectly called "photoelectric-effect paper"). If you watch my video about Compton effect (ruclips.net/video/Ap9os356CZA/видео.html), which completely confirmed Einstein's hypothesis on light quanta, you can see several instances in which people like Planck celebrated and supported Einstein although they considered his light-quanta to be nonsense. Even Bohr during his Nobel lecture in 1922 insisted that light quanta were not a real thing.
Absolutely wonderful video! Thanks for going further into the history and math of the light wave-particle duality! The De Broglie teaser surely sounds nice!
I think we are now ready for de Broglie's theory
Amazing video! I can't believe how beautifully you've tied everything together. Even those little side mentions of Bose's new method and Uncertainty principle hiding in plain sight, I wanted you to go deeper into! So fascinating
Thanks, I am glad when people appreciate also the little details that I like to include
Love the videos. They're always an instant must watch once I get the notification. Keep up the great work
Awesome, thank you!
10:58 1/M + 1/N very satisfying!!
beautiful, isn't?
Still haven't finished the video yet but it is interesting to see that it's denoted as . I am taking a (rather) introductory course on Statistics right now and we use E bar for denoting the expected value in the moment. That said, our E is expected value and not energy so it might be different. Still, Einstein did denote it as E bar in 4:25, so.
I think the bar is most commonly used by mathematicians; physicists used it until modern quantum mechanics appeared (mid-1920s) because the bar over a symbol can lead to misunderstandings when it is used for complex conjugation or spinor notation. The notation avoids that problem and it directly matches its use when Dirac notation gets introduced later.
Dr, I simply love your videos. With the addition of mathematics, it me realise how these scientists arrived to their discoveries and conclusions, even though the math is beyond my scope. However, your narration when u present the equations and how u manipulate them to arrive to the result, makes it Simpler for a person like me to follow along. Thank you for hard work you put in, making these high quality, well researched complex topics for us.

I just realized that I have been answering the question wrong. “Is light a particle or a wave?” I’d usually answer yes.
Now I am understanding it’s neither but it’s a quantum object that exhibits properties of both. 20:03

The fact that the matrix mechanics paper casually invented some of modern quantum mechanics just to get additive entropy sounds so insane
I am with you here, love the fact that Jordan just added this at the end of the paper as extra material but it completely started a new field and a new way of doing fundamental physics
3:33 How did Einstein come up with the idea to determine this derivative (the change of the average energy by the change of β (1/kT))? What was his physical motivation for this?
There is no physical motivation, it is a standard trick in statistical mechanics, in which there is a function called the "partition function" that can be used to generate many thermodynamical quantities by taking derivatives. Using this approach, taking the derivative of the average energy in reality is hiding a derivative of the partition function. In other words, after you take any introductory course on statistical mechanics and this is almost a natural to do.
Love your videos. Thank you for making them.
Following you the whole series. Excellent videos, as well as aspiring, I have always wanted to see the matrix mechanics in QM but haven't come by; it would be great if you could make a video on it. And can you tell me where you are finding these original papers?
An intro to the first breakthrough by Heisenberg and the follow-up matrix mechanics will come soon. All of Einstein's papers can be found in the link below; however, I don't include the translations in my videos because they are copyrighted einsteinpapers.press.princeton.edu/
Excellent video! This channel is the best. It explains thing without dumbing it down. I love the historical references, and how you explain how these things developed and how the interactions between the scientist were at the time.
I would love a video on matrix mechanics too.
Also: I read that something called SeaStar algebra represents a potentially deeper and more fundamental approach to quantum mechanics than the Hilbert space formalism. Do you know anything about this, and perhaps also how it can solve the measurement problem of quantum mechanics?
An intro to the first breakthrough by Heisenberg and the follow-up matrix mechanics will come soon.
I am not sure about SeaStar, maybe you mean C*-algebras, which is a set of mathematical conditions used for some types of Hilbert spaces, very relevant in quantum mechanics. There are also objects called c-numbers used by Dirac in the early days of quantum mechanics.
@@jkzero Seems like I misunderstood. I knew about the C* algebra, but I was under the impression SeaStar was something more than C*, but probably just because I did not investigate what I heard on a physics podcast enough.
Thanks!

Ladies and gentlemen the wait is over 🔥
Hmmm wouldn't the energy fluctuation formula show the distinction between wave and particle nature of light since M and N are accounted for separately?
How far can the values of M and N be from each other?
Are the number of wavemodes and the number of quanta even independent from each other?
Your content could be a really good basis for a semester-long elective for non-physics, technical majors with an interest in physics and history. Call it Classical to Quantum: The History and Development of Modern Physics, with the lectures being akin to your videos showing the historical context for each development, the course work being working through the mathematics to arrive at the results, and a final project of choosing and writing a paper/video demonstration of the development of some result in their major field. I think it could offer a unique way to develop scientific communication skills. I would've jumped at it as a young engineering student 😁
The majority of educational resources I've interacted with (articles, lecture series, videos, etc) seem to be written for either an expert in that field or a layman without a scientific background. Neither is bad, but they both require a lot of additional reading to understand fully (either for context in the former or more detail in the latter). Your videos fall perfectly in the middle, a splendid balance of history and mathematics, where I rarely feel other texts are a prerequisite for a full understanding of the topic presented.
Apologies for the long comment. Keep up the great work! I always look forward to your videos
I appreciate the long comment. You got me, what you see as video episodes here are my dream course to teach. I am sure that many STEM students would love to have such an introduction to modern physics filling the gap between superficial presentations and systematic courses on the relevant topics. I even think that this should be mandatory for physics students. I was one many years ago but I was never taught most of the stories that I have presented here. Many physics students and professional physicists have written to me because they had no idea about many of the stories and calculations presented here. So yes, thanks for the encouragement, it is one of my goals turn my notes into a course and/or a book one day.

Thank you so much for the deep study combined with the historical context.
I love the way that most fundamental physics is explained through an historical perspective on the derivation of matters and equations... Including the historical discussions and motivations.. It's very useful to understand where all this quantum physics come from. Today I just had a huge surprise to see that again a quantum concept comes from statistical mechanics...and I was thrilled to see how the seed to QFT appears already in a 1925 book by Jordan et al. Wonderful. Wooah!!!
Glad you liked it! Yeah, I find it fascinating that the last part of a paper casually starts a new way of doing physics, I had to share that detail.
The problem with the historical path to quantum physics is that it's false. They guessed the final result correctly, but most of the concepts that were used along the way are 100% false, so you are basically learning all the wrong lessons and none of the correct ones. The idea that quantum mechanics comes from statistical mechanics is certainly false. Quantum mechanics is a non-commutative solution of Kolmogorov's axioms, but it is NOT a slightly different version of statistical mechanics. The latter requires contact between thermal baths, while quantum mechanics requires complete isolation.
Thank you Doc for your vids, I binge watched all of them after last Tuesday and they have been very helpful to my sanity. Seeing this one come up on my recommendations was joyous.

You are amazing Professor 😍
Thanks, I appreciate that. One of the reason that I started this channel is that I miss teaching.
It is really amazing and well done video, chapeau.
So let me interfer with you as a wave and as an old-school physist, the Planck formula of a 'dark' body radiation (it is a very shiny object in IR range!) is derived under equilibrium conditions between light as waves and matter as quanta. therefore it is quite logic to have both nature appear in Planck formula. In contrast to open systems or out of equilibrium systems (more general optical systems), such as laser systems. In such systems the Planck formula is not a valid approach either for lasers nor for interference nor for diffraction phenomena!
Hope that would to clarify a little bit more the duality principle. the mystery of duality is still ongoing!
Dr MANI
Btw, on Einstein's assertion that light itself is quantized into photons (instead of quantization being a mathematical trick), I've seen sources that present the idea that instead of light being composed of flying photon "dots" while in travel, photons are actually _events_ occurring at the detector. The quantization ultimately manifests when *light and matter interact* . Notable sources are videos from the channel Huygens Optics:

Interesting that you mention this work, I had originally included the first hints to the 1916-1917 papers on radiation by Einstein but then I had to remove this part because it took the story in a tangent. But yes, I will make sure to come back to this work in the near future.

I didn't quite understand why it would be more particle like at high frequencies (or low wavelengths) and wave like at low frequencies? Isn't the electromagnetic spectrum continuous and therefore all any frequency is lower or higher relative to any reference point? Or is it all in reference to the planck length? Can someone explain?

It has to do with the quantum system the photon is interacting with. In The metal, there are discrete energy levels deriving from the structure of the material, therefore to extract an electron I need to give it at least the amount of energy that separates it from the potential of the vacuum of the other side of the metal/vacuum interface. This quantity is a constant dependent on the properties of the metal and is known as its "work function".
A free electron is different, it can take on any energy level, so when a photon interacts with it the energy can be distributed between the two in a continuum of states. However, they also need to obey momentum conservation, which is why the electrons taking part in compton scattering are not actually free, but bound to nuclei with which they can exchange the excess momentum needed to obey energy and momentum conservation at the same time. The electron can still be thought as approximately free because the energy of the incoming photon is high, so that the discrete gap bounding it to the nucleus is negligible compared to it. So it actually all depends on the energy of the incoming photon: if it is very high compared to the electron's binding energy, then you can have Compton scattering, if it isn't, you won't
@@raffaeledivora9517 That was a beautiful explanation. Thank you very much for that. So if I understand correctly, the photon is not an indivisible packet of energy, and the actual "quantumness" is exclusively a property of the electron who's ability to absorb light energy and convert it into kinetic energy is dependent on its state. Well, that just makes everything make sense. Thank you again.

I disagree with the analogy at the end of the video. When describing the light wave-particle duality theory, we are dealing with unknown unknowns and abstracted away from the reality by layers of calculations with some foundational assumptions.
In the case of the gameboy and Walkman, we can clearly define the terms and its is not at all surprising that one device could have both functionality.
@2:11 "a course in sadistics"?
Sonwhere is the math that shows N is not just a counting of wavemodes related to emissions from the material of the cavity, aka how many quantas worth of wave energy is in there? I don't see a duality just an accountant counting energy.

Now imagine breaking that barrier.
It is very confusing calling a massless quantity for a particle independently which other properties it exhibits as the masses are so central and to be honest, not explained at all until today. Light quanta is a good name for photons.
Mass is effective mass. It's just an effective dispersion relation, not a fundamental quantity. There is ontologically no difference between massive and massless field quanta. They are all combinations of energy, momentum, angular momentum and charges. The only difference is the relationship between energy and momentum.

To the concluding question posed at the end of this video, Yes, just look at an Electron Microscope
Yippe!
The video title is a misnomer: studying the statistical distribution of emissions by electrons tells you something about ELECTRONS. I don't understand why some people bend over backwards to claim "quantization of light ", while observing electron dynamics.
Light is neither a wave nor does it consist of particles. It's the excitation of the electromagnetic quantum field. The so called "discovery" of wave-particle duality was a trivial dead end. Nature doesn't work that way.

4:44 Einstein finding something found earlier by someone else. What a surprise! 😂
Wave is wave particle is particle. Simple. Particle can not be a wave. You have to detach from this 100y old wrong idea
Photons or light is modelled with complex numbers.
Real is dual to imaginary -- complex numbers are dual.
Photons or pure energy is dual -- probability waves are dual.
Structure (syntax) is dual to function (semantics) -- proteins in biology.
Protein shape or structure determines their function or behaviour (purpose) -- protein folding is dual.
All life is built from proteins.
"Always two there are" -- Yoda.
The Schrodinger representation is dual to the Heisenberg representation -- quantum mechanics is dual.
Everything is Ok but why do you always pronounce "s" instead of "z"??? Is it so hard to pronounce correctly?
Pretty sure those are German names and in German z is pronounced more like "tss"
@robertstuckey6407 German title Zalzburg he pronounces like "Saltsburg"...
Thanks!
Thanks so much for your very generous support.
I’d like to see some numerical examples to fully appreciate the role of wave modes vs. photons in different circumstances.
