I really hope this channel keeps uploading content, it’s a gift to humanity

Please dont stop bringing content like this. It simplifies concepts that take months to understand in colleges and I can even visualize it. This deserves millions of views I hope you reach there soon! All the best

I currently have the (electro)magnetic chapter in physics, so this is actually very helpful!

6:01 it is worth noting that some animals can actually see light polarisation, eg. some insects recognise polarised light and use this ability to detect pools of water (its surface reflects light with horizontal polarization more strongly than with vertical polarisation), kinda like they were wearing polarised sunglasses. Fun fact is that even some humans have very limited ability to see polarisation - look for "Haidinger's brush".

without a doubt the most clear, thorough, and engaging science education content on youtube. no stone left unturned, all perfectly parseable. you are a treasure. thanks so much for what you do.

You are simply genius physicist. I think none in world right now has such talent to explain very complex phenomenon with beautiful demonstration or animations. You caught human mind's ability to understand pictures in motion...

Watching this channel is like having a secret master key to the unknown that you can temporarly use to access the mysteries of the universe. Amazing as always.

Thanks for making these. I want to show my support and hopefully make it worth your while to keep writing and producing these types of videos. Happy holidays! I look forward to your next release.

Today I learned why the sky is blue and how 3D cinema works. Thank you!

Thanks! It was a great video, please keep making these . You covered a great amount of knowledge into this small video.would love to see more of these !

I have always wanted to know how polarisation and especially the emitation of EM-Waves from objects that are heated up works. I asked my physics teacher, and even my dad who studied Physics, but they didnt really know. This video explains it so well, that I understood it at first glance! Thanks!

Alessandro Roussel and Octave Masson-you two are the very best; good at public speaking, using resources at the highest advantage and make learning fun. Thank you for the hard work and effort that goes into these videos. We definitely appreciate it.

This is the best physics channel on KZfaq, and I've watched many. It's ability to cut right to the heart of a concept, explain it in simple terms, and apply that principle to explain disparate practical phenomena

I’m stunned by your simple, clear and yet comprehensive and sophisticated explanation and presentation. I can bet reading old school physics books wouldn’t help understand electromagnetic waves, the way your 12 minutes clip would help. Much appreciation

Wow! I am 50 years of age now and from the age I went to, what was called Middle Technical School or MTS here) I had majors in Chemistry, electrical engineering / technology , physics, mathematics and all. Every major educated their own little part of the whole story and up till now I haven't seen a combined basic explanation like this which should be the basis of all above mentioned majors! Why, because your video literally gives a concrete understanding about the foundation of all that's teached and how all the bits you learn is actually just one basic fact about particles, matter, how this behaves and what follows as a consequence out of this fundamental behavior. In my quest to such an explanation as I wanted to now exactly this, people only repeated what was said in school or evade an answer by saying that it is to complicated to explain. And here you are (!) doing it in twelve and a half minutes! This basis shows also what I already thought for years and just recently showcased by the wonderful youtube channel Veritasium by Derek Muller. That, in electrical current, it's actually the electric-magnetic waves that carry the energy and not the flow of electrons, because electrons hardly flow anywhere! They just pass on the electric energy to their neighbor and the electro-magnetic field which they create through the excitation brings the energy over to the other side. That's why the material of the wire, their width, wheter it's a bigger solid core or separate strands and isolation can make a huge difference in how that current or signal is distorted or not. Also, as all matter interacts with each other through their electro-magnetic fields, no matter how significant. As such, we, as a big lump of matter, radiate the combined and averaged result of all the matter we exist off and unconsciously influence each other fields. Most people would say that the influence is so insignificant that we would even notice it, but it would explain a lot of phenomena in which people "sense" something that they can't explain like somebodies mode, intentions or why sometimes you feel attracted to somebody who, physically, at first appearance wouldn't attract your attention. Maybe a bit far off, but not in the basic sense of this fundamental physics fact. Long story short, Incredible how you managed to bring this subject so clear and yet in such a short amount of time!! Thank you so much! ☺🙏

Love your videos. They really help improve my level of understanding of the universe.

This channel is the best at explaining complex topics in a simple and easy to understand way.

A new ScienceClic post!!! I love this channel. Octave is a fantastic narrator, and the content is always engaging and hugely interesting. Thank you!!

I've seen a lot of videos about this topic and this is the very best. The clarity of the explanation and the visual representations are above anything I've seen so far.

Crazy how this video sums up 5 different experiments that I have had in my first semester in the Physics laboratory!!!

It would great if you could somehow visualize how a classic EM wave arises from a number of photons of the same frequency, and what it means for a photon to have frequency in the first place. Thanks for all the videos.

This is awesome! I usually just think of light as particles because wave particle duality is hard to think about, but there's so much more to be understood using the wave interpretation.

You have no idea how much of a difference this channel is making. It reimbursed my love and curiosity for science. Please keep on working.

Please, if you could make such an animated video on the physics of conductors and insulators (dielectrics) -- especially polarization of dielectrics, that would be unbelievable. Your animations are changing lives -- please don't stop.

What a phenomenal video. As an A-level Physics teacher, this is pure gold.

This channel is criminally underrated

I'm in my 50's. I studied IT but also studied numeric analysis and some higher mathematics. One of my friends (mathematician) went through Special and General Relativity with me. I understood some of it but never understood it properly. Thanks to Alessandro Roussel, now I do. You're an awesome scientist, mentor, teacher and human being. 🥰 I just want you to know that. Your channel is BY FAR the best explanation of difficult scientific concepts I have ever come across. Your channel should be compulsory viewing for all Physics students in the UK.

I’d love to see an in-depth video on quantum entanglement. You’re definitely the best channel on KZfaq for explaining physics

2:37 Awesome! I have never understood the source of thermal radiation or incandescence before. Everyone always talks about luminescence and the source of those photons, that’s easy to find. I just have never been able to find much information about the source of photons from Incandescence. Looked all over Reddit, KZfaq, Wikipedia and there’s literally only a sentence about it on Wikipedia, I checked the articles for Thermal Radiation, Electromagnetic radiation, Black Body radiation, Incandescence, and the only thing it says about it is “The kinetic interactions among matter particles result in charge acceleration and dipole oscillation.“ which didn’t seem helpful at all. Those articles are all huge, I can’t believe they didn’t say anything else. It seems pretty obvious now. Thank you!

bro casually explains 10x all of high school physics in 12 minutes with 300% understandability

I'm really glad that people like you exists, you explain that well this topics and get people excited to understand them.

This is by far the greatest science-education channel exists on KZfaq! The music is just LOVELY

He just explained the wave behaviors!! His videos are always amazing. You can tell he puts time and effort into making each video very wonderful, keep up the great work!

Your videos are in different leagues, true knowledge. Thanks for your hard work.

This is the greatest explainer video on electromagnetism I have ever seen. Everything is tied together well and is presented so clearly that you literally can't help but understand (given the minimal prerequisite knowledge). Thank you, so much.

I appreciate the clean and straightforward approach to these topics. They are presented so well that a complete novice in science can grasp at least 50% of what you present. Thank you.

I was reading up on Cherenkov effect just a couple days ago, and this explained it so much better than any article. I love your videos, very easy to understand while at the same time going into more depth than usual.

Thanks for another excellent video. Clear & informative. These videos are always worth watching at least twice. With every video I learn something new, or re-learn something I'd forgotten. Please keep them coming.

Thanks much for describing these concepts with such wonderful artistry and clarity. The enthusiasm and sincerity is most evident. Have a wonderful New Year filled with beautifully shared illumination!

Amazing video! I have been searching for a proper explanation of electromagnetic waves but I didn't find a video remotely brilliant and well-explained such as this!

This channel is just amazing. Such clear explanations. It feels like it should have way more views and subscribers

Clear & concise. Thank you.

I have watched a bunch of stuff lately to try to understand EM waves, and this one video had several moments where my understanding improved. Excellent.

This is genuinely the best explanation of electromagnetic waves amongst tens of previously watched videos. Can't thank you enough!!!!!!!!!

These videos are absolutely fantastic! I could honestly listen to and watch a ScienceClic video about this for hours... I'm always introduced to things through these videos that I had no idea about. I learned the basic information, like reflection and refraction, but I never learned about their inner workings. And some things, like why the sky is blue, have been answered elsewhere, but this explanation is still unique and gets more into the physics behind it. (I would have liked to have seen info about red sunsets as well... Maybe in a future video...) The worst parts about your videos are when you say things like "Finally" or "To sum up". I just don't want them to end so soon!

The way you describe physics is really neat. You are clearly gifted.

Thank god I found this channel. And of course you for making these videos. I had accepted for a long time that EMW are something that can’t be really explained rather we only observe them. But I have a hard time to really be fascinated without a clear explanation of the HOW and WHY. That is why I LOVE physics. It’s the world view that is changed.

This channel literally expands my imaginative perspective as a person who wants to find the theory of everything. Thank you for your amazing animations.

I'm an Electrical Engineer and it's nice to have more of the physics side of the equation so we can understand what were simulating when we make 10 million assumptions and approximate equations.

it was very cool to see an explanation of reflection since I had little luck finding it recently. But I would also really like to see more in-depth explanation on how interference work the way that angle of reflection exactly matches the angle of incident.

The fact that "jiggling atoms" (Feynman's explanation) is connected to heat never made sense to me - until now! Brilliant explanatory video. Keep up the amazing work Alessandro!

Best Physics channel on KZfaq

I can't believe how easy it is to understand content from this channel. I wish we had this when we were in school. Amazing work!

Wow. The 3:54 - 6:00 on polarization really clarified things for me. I comprehend it much better now. Thank you.

I had some questions which maybe you could address in a future video: 1. You said that when a charged particle moves, it produces both electric and magnetic waves, but didn't mention why it has to be particularly accelerated, because I had studied in high school that moving charges produces only magnetic field when at a constant velocity, and accelerated charges produce em waves. 2. Why does it actually bend during refraction? I slows down because the field interact with the atoms inside it, but why bend? I mean what is the mathematical equation behind it. Huygen's principle can explain it but it doesn't explain from the perspective of the atoms. I have an engineering degree but didn't study physics after school, so I watch these videos, and would like to thank you for the quality content you put out here.

This is the clearest, yet in depth, description of the wave nature of light I have yet seen. This will be shown in my science class. Next, I would love a video about the particle nature of light i.e. ultraviolet catastrophe, photoelectric effect and compton scattering.

Love this channel so much. First watched the video on string theory as I followed Thomas Harvey's works since then. Never stop making these videos at this quality. Would love a more frequent upload schedule, but quality over quantity. Could you try QCD next?

Good quality video and finally I know the proper reason why light refracts, thank you soo much for your hardwork and beautiful illustrations.

Very well presented. Clear narration, and at a speed that was not to fast to be absorbed by us slower thinkers.

I never had a good formal education in physics and I suck at taking exams, but I have been fascinated by science since childhood when I began studying physics out of pure curiosity and enjoyment. Between your videos and KZfaq my education continues!

I'm learning about elecro magnetic waves by the help of electro magnetic waves 😂

This has completely updated my understanding of electromagnetism and it's phenomenal ❤️

That was probably the most beautiful introduction I've seen on this topic.

the way he explain things get so clear.Wonderful teacher

Thanks for the great visualization and explanations. You are my favorite channel. Also, Musique mystérieuse is such a focussing piece of music that I use it while studying. I can focus on the subject for hours while developing software.

I think we haven’t been visited by aliens yet because they found this channel first and got all the answers they would have wanted

Amazingly well done! Easy to understand and answers so many questions effectively! I enjoyed this greatly.

The writting and narrating of this channel are just amazing!!!!

As usual, Scienceclic produced the most understandable video on complex topic👏👏

Fun fact: typical 3D glasses DO NOT use linear polarization (mostly because tilting your head would start bleeding in the wrong image for an eye into the right one) but circular polarization (which is immune to this issue); but this can play merry hell with the heads of folks who are only used to how good old linear polarization (think LCD screen foils) works, as in two filters 90 degrees to each other = opaque, rotate one of them another 90 degrees = transparent.

Hi. I have watched around 100 videos regarding this section of physics. Of all that time I spent watching men's explanations of light propagation and creation, of all those videos, you made the clearest and most concise one. It is significantly better than anyone else's.

Awesome!!! i studied about reflection, refraction absorption and scattering of light in high school, but i didn't knew why did it happened, you've explained it in a very articulated way , thanks man!!!

If you ever can, upload a video on fluid dynamics, its often and overlooked subject in its potential for intuitive "aha" moments but it's worth a shot for sure!

Thank you very much , even though i go into thinking of why everything happens you have stated out everything clearly and you have given me something to think of and ponder about , also the animation is just so cool

No channel has allowed me to understand these physics theories and concepts better than ScienceClic. The animations are truly the closest thing we have have to visualizations of these phenomena.

This is superb. I am amazed by, and grateful for the verbal clarity, and the beauty of the illustrations. Thank you .

Your videos make visualising and understanding things fun and exiting. Thank you.

Awesome, thank you for posting :)

This is about the best video on electromagnetic waves I've seen. Well done!

This video summarized and explained more than a whole semester in the college. Thank you very much!

Love this channel so much: Quantum Electrodynamics next?

Loved it! Now do the QED interpretation of the phenomena described here.

bro what a legend you are. nobody explained this concept this clearly. you cleared all my doubts . thank you this is what i was asking when i asked someone what is an electromagnetic wave

ScienceClic is the BEST science channel on KZfaq!!!

Love your content! Pls keep posting more videos like this💯

Pls, make a video about. Bell's theorems. How to find hidden variable? And also about hiw probability in quantum physics work?

It's nice how a lot of info is put together and got connected in a way that made it easy to understand and remember

This is very good. Compact, to the point, understandable. Thank you. It was a long time ago when i learned thus much in thus short time. This is because you tell the essence of the cause of the explained phenomena, as it is, without side-excursions and without leaving out something necessary.

Enjoyed every second keep up the good work

at 4:40 you say: "The sun's heat is transmitted from its surface via electromagnetic waves through the vacuum of space." What exactly is being transmitted in terms of substance or matter? Do these electromagnetic waves physically exist as objects?

This is so good! Also your other videos about quantum mechanic stuff .... can't believe it can be visualized and explained so well! keep it up! One of the best science channels!

This is really really good content. No easy topic and also not easy to catch everything right away but maybe the best explanation possible to understand this complicated field.

One of the best videos about electromagnetic waves I've ever seen. The only thing I didn't really get, is what are the directions of electric and magnetic waves (when we are talking about polarization). Are they directed such as mechanical wave's top and bottom points? Or it is just a simplification like image of an EM wave as a sinusoid?

Awesome video :D Just some feedback: Could you look into using a de-esser for your microphone as its really harsh on the ears with those high notes.

This channel is top concepts of modern physics book crammed into quick and easy to understand videos with stunning and accurate visuals.

Wow you explain thing in much better and more accurate way than anyone else on YT! Thank you!

Sir pls explain about quantum tunneling

Woah I forgot about this channel and I just rediscovered it. Amazing videos.

Well I'm sure you've already heard this a million times but you have no idea how much this helped, thank you.

Oscar Shu 0 seconds ago I work as an EE engineer for a decade, I thought I knew electromagnetic wave well in my daily work, but I still learn so much in this video, really like the explanation for diffraction, reflection, refraction from the perspective of atoms and how light wave slows down in material but the speed of light did not change.
