great video! a lot of profs have hours of videos online, but no one understands what they are trying to say...

I finally understand what I got wrong in my midterms...I had a misconception...thanks for this clear explanation

Nice

Very nice.🎉

This is false

Im a Saha too😅

Muy bonito y toda la teoría del ruso pero viola la segunda ley de la termodinámica Y Cómo dijo Homero aquí en esta casa se respetan las leyes de la termodinámica😂😂😂😂😂

Examples of real physical systems or simplified models for such, that don't satisfy detailed balance? Or even more interesting,are there any that don't achieve equilibrium but forever oscillate somehow? Sorry but such questions have pestered me for a while now... thanks for presenting detailed balance in this way I found it interesting .

hi very nice presentation In r direction there not radiation?

great video, really helped me sanity check something for my research!

stop yapping

Thank you for sharing your knowledge. Much appreciated.

thank you for your lesson, very clear

0:39 Is there not a density factor missing in this integral? And in the second term on the RHS of the radiative transfer equation.

Excellent simplistic explanation, keep up the GOOD work !

Best explanation!

Thanks a lot!!

Good explanation

Thank you, very clearly explained! Super helpful

Watching this a day before my Radiative Processes exam. It honestly cleared up so many questions I had about the subject.

Fantastic, thank you very much for that explanation. Could you please suggest a book to learn more about Inverse Bremsstrahlung Absorption and Fresnel Absorption.

Very clear explanation. Well done.

Yes... amazing....! Perfect video for EEng...thanks for sharing

my goat

excellent video

Outstanding, but its not obvious current has that factor \sqrt( n A L)

While your explanation is clear and easily understandable (good job!), the theory of what’s going on is totally bonkers! 😂 First of all, let’s be honest, okay? Honestly, can you say that you have ever in your life “seen an electron” either “in the lab” or from the reference frame of ‘the electron’ itself? I think not! That would be like me talking about that unicorn ‘I saw’ in my backyard last weekend! 😂 It doesn’t exist. So it doesn’t matter what imaginary reference frame you are talking about… unicorns don’t exist, and neither do ‘electrons’. 😂 Now the explanation for synchrotron radiation is rather simple… what you call ‘an electron’ is nothing but a transverse electromagnetic impulse in the Aether medium. It’s a wave of luminiferous Aether, nothing more, and it contains both current or ‘charge’ and it generates its own magnetic field 90 degrees perpendicular to its direction of travel. So, the reason why you have synchrotron radiation is because you are essentially colliding two magnetic fields together - one magnetic field from the ‘electron Aether impulse’ with a second magnetic field of the magnetic field of the cyclotron itself and that collision of two magnetic fields causes secondary emissions or waves in the Aether to occur. Those secondary waves are what you call ‘photons’’ or ‘Xrays’. And that is what synchrotron radiation is in a nutshell. It has nothing to do with Relativity, time dilation, or Lorentz contractions…etc…

very helpful!

Very nice explained for me that has installed e TS experiment and obtained nice spectra. It would be interesting to hear a lecture that include a large magnetic field. I think that maybe the cross section could change. It would be needed to add the Lorentz force F= q vx B I think. Congrats

This is a masterpiece of a summary. What about a follow up video of any new science discoveries in the last 10 years that have impacted or answered further questions which you’ve laid out?

@ 2:29 Make that - 1/tau. Then we have exp(- (1/tau) . t) and a decaying exponential.

6:19 Nu is frequency of what?

Wow! ❤A Must Watch, again 👌 Thanks for Sharing ! Hope all is Well, ❤

1st!🎉 hello?? 😅

Im Here!🎉 9yrs later❤😅

@ 4:32 So its probability is very, very, very small.

very good video, so much thanks

Amazing video! Thank you for the explanation ❤

Good job! A very clear explanation.

Thank you so much. I was nervous about my spectroscopy exam cuz I didn't understand these concepts well, but now I understand much better by your explanation.

thank you so much for the great explanation

Aaron, love your videos. Well-produced, informative, and to the point. Thank you.

Nice explanation. Thank you for sharing this. This made it really easy to understand those previously mysterious Einstein coefficients. I kept coming across those with regards to radiative transfer and line shapes, but didn't really understand them.

I've never come across a nicer explanation of this. Thank you! It's very understandable.

Really amazing, from great explanation and analogy to precise and rigorous foundations. So, Thanks!!

Thanks! Finally I find a clear explanation of the concept!

I love considering how people might've discovered these phenomena. Because obviously we're learning from the motion of the electron upwards but scientists probably noticed noisy current out of the resistor and tested different environments to discover it's cause. Fucking love that.

Amazing! Many thanks for uploading this, Aaron. It was very helpful.
