This is the kind of high quality physics content that is lacking on RUclips. It doesn't skimp on the details and doesn't dumb down the content for its audience. Superb work, well done
It might be true for us, that we know and love science. But maybe other people find to "hard". Which doesnt mean the video is superdope. Subscribing right now
I let the advertisement before the video run in full, I really want the creator to get paid well. This is incredibly well explained, bravo to the creator! I wish they had an award for scientific/ educational video such as above for RUclips. The world needs more of this type videos that enlightens and educate the people, this is why we Internet pioneers worked day and night on open source internet in the 90s, so educational materials like this can flow freely and free mankind.
Another remarkably lucid and insightful video; we are SO fortunate to be able to access educational masterpieces such as this. THANK YOU. I came to this after listening to an old episode of BBC Radio 4's "In Our Time" series" on the subject of the PHOTON. I'm a huge admirer of Melvyn Bragg (the host) and regard the "In Our Time" archive as an intellectual treasure trove and was therefore shocked that the three SMEs in the studio, after spending 45 minutes on the wave-particle duality of light, concluded by saying they don't personally believe it; these were not "electric universe" nuts or "flat earthers" but tenured faculty from major UK physics departments! Based on your video, it seems Compton set out, in essence, to replicate Einstein's Photoelectric work with X-Rays instead of UV. It is remarkable that, in his apparently triumphant overthrow of Maxwell, he regressed all the way back to Newton and billiard balls; quite astonishing "out of the box" thinking.
Thanks for the feedback. I can guarantee that there are plenty more videos on their way. Only problem is that they take a very long time to make! The next one is almost ready - it focuses on the Bohr model of the atom and the explanation of emission spectra.
I thought this was a 3brown1blue video. Dammit, I'm still reeling from the Planck constant one. I'll bookmark this and watch it in the morning. edit: Excellent explanation. Very intuitive with no maths stone left unturned. Thanks very much for posting. I like ViaScience's videos which are similarly well done, but your added touch of history and my native British accented narration is very welcome.
@@PhysicsExplainedVideos I know many have told you how amazing your work is. I just wanted to thank you, your videos convinced me of taking a major in physics.
Thanks for the feedback, I really appreciate it. My intention with these videos is to provide a detailed insight into the actual calculations performed by the pioneers of quantum mechanics. I find the history of these ideas fascinating.
I am surprised why so few has subscribed. such top quality stuff . then there are people Vlogging walking around in the PJ's at home and they have a million subscriber. Dont get it at all .. Good job. thank you very much .
Awesome. A clear and elegant video. Shows all the important mathematical steps and gives the essential historical context. Wish all physics videos were just like this.
Fantastic video. I'm about to start studying Compton scattering, I wanted a good introduction which didn't skimp on the physical background and maths, and this ticked every box. I'll be sharing this with my fellow students.
I just found this channel and instantly subscribed. RUclips channels giving science at this level are rare. I love this. This channel will explode. Make a patreon, people will pay for shit like this.
One of the best physics channels out there! Please keep up the good work! I highly appreciate that you don't shy away from some math here, makes the thought processes clearer, not more difficult.
When I took Physics in college years ago, I was wondering about the term Quantum Teleportation. You've remarkably explained how it's possible! Great job!
This guy is a genius. I wish I had access to such a excellent quality of videos of when I was in highschool. Love your work keep it up bro. Edit: You just got a new subscriber (+1)
This is my third visit to this video, and not because I did not understand it the first time. It's a beautiful video packing seamlessly the actual drivers towards learning a concept-the motivation and the wonderful implications. I'm sure this is not my last visit. Thank you for such content!
I would hate to put you under pressure as I don't want you to lower the quality of your videos, but I... want... moreee!!! But all jokes put aside, your content is excellent and I really enjoy watching them! Keep up the great work!
This is a fantastic video. As a physics student who enjoys the history of science, to me this video has the perfect ratio of explanation to rigor. Easy sub and will share.
I really enjoy your videos, and I hope you keep making them, amazing content. I would maybe suggest starting out each video with a stated goal and a summary of the steps you will take, then periodically checking back in with those steps as you move along. It would really help the viewers stay engaged with your process. Thank you for your work on these, they are a boon to youtube regardless.
Yup. If you replace the momenta with the sides of the triangles in the diagram, you get a proof of the law of cosines. This happens because both momenta and lengths of triangles are proportional to the sines/cosines of the relevant angles.
At 12:20, what it means “ the electron is strongly bonded “ ? Sounds like a miracle exception from Neil Bohr’s model of atom in which the strongest bond is in orbit 1. BTW, is there any chance that some photos didn’t hit anything when passing through the material? Or any chance some photos encountered with the nucleus?
Brilliant, it's ages I had to do this at high school but it was fun to see this presented in such a compact way, with a few less shortcuts and so much more readable than my teacher's blackboard writing :)
Never stop making videos, the way you plotted is really cool, it helps me to bring a new aspect in itself. I cordially thank you. Bring these types of videos more with mathematical expressions. Your new subscriber :-D
16:38, I have a doubt sir. This doubt could be very silly, but after you multiply both sides of equation with c, delta p.c can be thought of as delta m.v.c which isn't equal to m.c² since the velocity of an electron can never equate to the speed of light, hence how can u say that it's equal to delta E? And I know in Heisenberg's Uncertainty Principle, Delta refers to the Gaussian/mean distribution of the probability of finding it at many energies when I measure it. And the peak of this Energy distribution is greater than or equal to h bar times c divided by 2L
Another theory is that.. the delta p stays as it is. And since electron can't exceed the speed of light, the mass (m) in p = m.v starts to increase once the v approaches c. (Assuming delta L is approaching a very tiny scale) and the mass simply increases. No need of mc²
Thank you for the great explanation and the nice proof. I want to learn more about other types of scattering too. Rayleigh Scattering/ Raman Scattering / Mie Scattering. And of course, would love to see the continuation to QED. Keep up the good work!
Love the timing. Watched another video of yours several hours ago, and saw you just uploaded another! I've been (casually) studying for the knowledge of a degree in several areas, including theoretical physics. Great quality, it's a lot less boring watching videos like this that are so well done. I'll be referencing these from time to time xD +1 sub
So many comments, have not seen a single question/critique. What could it mean??? 1) 17:00 why energy should create an electron? Why not create a photon(s)? 2) 2:45 What do points apart from peaks represent - why are there other wavelengths? P.S. I join others with praise - good videos overall.
04:32 Please clarify: you say "some of the photon's energy is transferred to the electron" - I thought the whole point was that ALL or NONE of the energy was transferred, "some" isn't possible, hence quantization?!
Amazing. Just amazing. Hunch 1: You are some kind of an educator and this was motivated out of quarantine necessity I suspect? Hunch 2: You did this in ppt right?
Amazing explanation, from the basics to the advance. Love it, keep up the good work. I see your channel has very few videos but they are the best. I wish you do more videos. ☺️
I see. Just one more question, if I may. How does one prevent the parts of my brain that melted, from leaking out my ears? Asking for a friend, of course.
With eardrums intact, there is very little likelihood of drainage via the ear canal. Much more likely, drainage will be through the lower sinus into the back of the throat. There is a theory of how rapid and numerous doses of a fluid called Tequila can slow and even prevent the melting in the first place, thus greatly reducing the risk of drainage. Hopefully, this helps your friend.
Regarding the principle of energy conservation (as discussed around 8:12), why is it always equal before and after? Could it be possible that some energy is lost immediately before and even during the collision of the particles due to some form of interference or other factors and therefore the before and after results are not equal?
Awesome video, at a level of detail appropriate from A-level to masters study. I have seen the derivation done very nicely considering the photon & electrons momenta using the cosine rule for triangles, but there are many ways to skin a cat. Keep it up!
Cheers for the feedback. You are spot on, I have aimed to make these videos accessible to A-level students who are willing to put in a bit of hard work, as well as make them more generally accessible (at least that is my hope). Thanks for taking the time to leave a comment, very much appreciated.
