You are one of the best science historian here in youtube, and far better than the ones I knew when I was in college. Thanks for this video!

Thanks for this wonderful video. Every physicist knows something of these stories, but you are putting them in the context of real history. Planck, Einstein, Bohr, Boltzmann, Schrodinger, and Edison vs Tesla and more are becoming more vivid to me.

Fantastic. The fact that Planck and Einstein were buddies who had a little band together warms my heart. I wish there was a movie about their friendship and discoveries

I love this stuff. Putting this together and presenting it like a history lesson and avoiding getting bogged down in mathematical minutiae is so enjoyable to watch. Thanks!

I wish I had discovered this channel earlier. It is unusual to find the details of physics and history intertwined and not dumbed down. #consilience #howtounderstandeverything

Great video! Thanks a lot. Had a lot of fun captioning it too... Can't wait for the second part!

That was awesome! Thank you for gathering all this together in one video.

Kathy, of all your wonderful videos, this is one of the best! Seamlessly weaving the personal with the scientific information truly brings the stories to life. Great stuff.

Thank you for your work and stories and for speaking clear, easy to understand English (for the non natives ) it’s all good 👍🏿 😅

Your videos are excellent. In addition to the stories, they bring us scientific content that I always liked.

Hey! It's finally here, nice looking out Kathy. PS it's as awesome as expected.

His brother Sam had a nightclub in America. I left my heart in Sam Plank’s Disco!

I have only recently discovered your videos, I love the historical bits that you have compiled.

Brilliant and entertaining. Human and heart. Well done!

You are just wonderful, I just found your channel . Some how you have made a video about everything that I’m pashonet about. Thank you .

Thank you for your videos. They are well researched, to the point, very interesting and sober. I especially appreciate the fact that you do not try to sensationalise your material in a misguided attempt to generate “interest”.

Such a hero ❤️. Thanks for making such awesome video

First video and I'm subbed. This was great. You have a way with words and your delivery is excellent. I stayed focused throughout the entire video which doesn't usually happen. I can't wait to see part II.

Thank you for this video. By bringing Planck to life the lesson is made so much more interesting. Not being educated in mathematics, I was only tangentially acquainted with Planck so this was very enlightening. Great work.

Thank you. Thank you so much. An inspiring story. Really love listening to you. It reminds me of my physics and chemistry classes from over 30 years ago

Very informative. Thank you!

Thanks for all the love and effort you put in your videos!

Thanks! Can't wait for the next videos!

WELL DONE. It is so good.

Wow! Living the life. Thank you!

I loved how detailed yet how concise you made it! Being a professor, I must say your zeal and delivery was fantabulous! Cheers!

thanks Kathy ❤

Wow, you're great. I'm glad I discovered you :) - I'm glad You discovered you and make these.

Thank you. Thank you for Planck’s quote on entropy being an additive magnitude and probability being multiplicative. I never understood the origin of Boltzman’s constant. No professor or book has explained it so succinctly as Planck!

You are such an amazing Teacher

Also it appears Max invented the Rockabilly Hairstyle way back when! "Go, cat, go!"

Thanks Kathy, love your videos as always. I always know more after watching your video, no matter how much I thought that knew before watching.

Congratulations for all your videos! They are all so well documented and well told thay I've rushed over almost all of them. What about astronomy? There are fantastic histories there, like the one that Johanes Kepler was so miope that he never saw a single star and, yet, he came with his famous three laws, thanks to the histeric Tyco Brahe's data. It's a lovely history!

Excellent as always !

This is great. I love listening to her!

EXCELLENT AND VERY INTERESTING.

Thank You !

You, "Darling" are fabulous! So enjoyed this video. 🙏

Kathy ,you"ve done it again,still love your channel and my young ones still use you channel as a learning tool,keep up the good work!!!

Thank for a very interesting and informative presentation.

Superb! Thanks for doing this!

his genius is amazing; he's a very funny man. Great wit and hilarious. Great German man; lol...

I wouldn't want to be a bystander in your videos, Kathy 😛 Can we call the Solvay Conference the Mustache Conference? All the men but one or two had mustaches.

Thank you ❤❤

Youre just amazing!!!

I would give a penny to hear the duo of Einstein and Planck

Suchna great video. It shows how one discovery is related to another in science.

Thanks for all video

great video, thanks :)

Thank you for this very interesting lecture from Germany Graduate from Max Planck High School Kiel

obdurate - you nailed it. Thanks for another well crafted video.

Thanks

I like Max Born another blessed physicist!

Looking forward to part two.

Fantastic insight!

Kathy Loves Physics, History & E. Rutherford 😁

Great video💚 but I expected better (to talk about his early life in Berlin, about his enthusiasm as a young man, and about the German government’s investment of millions in the Technical Research Institute in Berlin where Planck’s appearance was from there) But I loved it very much especially the Nernest part and the Solvay Conference I did not know this before Thank you **I have added an Arabic translation to the video and I hope that it will be accepted .

your videoe are highly interesting and helpfull thanks

amazing woman.....AMAZING YOU LADY

This should have a million views.

Love the video. I always got bored with classes like business statistics so I bought three or four books on the history of Math, and found I could easily take the teacher off subject and into more interesting discussions on the people's lives and history in the given formula of the day. In concern of your discussion though, at time 5:54 when you say, "but then Planck had a problem", I feel (by experience in studying math) you may have skipped two years worth of pre thought, scientific introspection, and re-hashing of everything he had read and learned, not a fault of your speech, in fact it was said well, as most math teachers all uniformly use the same language in proofs, for instance, "It therefore follows", usually means twenty steps later in the proof, :) I feel there is a bit more I will be looking into to explore what the two or three sentences involve, after that time stamp. The inability for anyone to explain the physical relationship of Plancks constant to the classical physics has always upset me. Currently I am believing Frank Znidarsics explanation of Plancks constant as being that missing classical physics link, "simply put", by considering it derivable by finding the change of velocity from a standing wave to a traveling wave of a electron wave, and placing that inside hooks law for springs, and searching for an impedance match in the system. alienscientist.com/files/Znidarsic.pdf

Damn this is interesting. keep it up!

Great videos. No need for me now to hurt my eyesight reading books.

Awesome

Thank you very much please don't be late

I am going to reread George Gamows book "Thirty Years that shook physics" because of these videos.

this genration of scientists were great with the limited equipment they had using their minds they peeked into the small things of the universe

One of a kind, brilliant, funny and creative, That is (Dr. ) Kathy, not Planck. Thank you for another fabulous lecture. I love this channel. Raphael NYC

Thanks Kathy. In my own ideas,entropy has to stop at absolute zero as there is no motion of atoms. If there is no actions of the particles,entropy has stopped.

AMAZING ! WHAT OUR ADMIRABLE MAX PLANCK IS AND WHAT HIS REVOLUTIONARY IDEA OF ATOMIC ENERGY ! THANKS !

Wow excellent 😘

Wish these have sound effects and fun video transitions. Otherwise these videos have amazing educational value!

MAM THIS INFORMATION IS IMPRESSIVE

your videos are awesome. Could you make a video on how Bose-Einstein letter and their collaboration made the concept Bose -Einstein condensate?

One of the amazing things about your talk is how you show this scientist influenced this one. Or this one was not influenced. Both important in seeing the science and physics moving forward and developing.

Thanks Kathy, another great video - fascinating and informative. I look forward to part zwei! So much cousin marrying is v disturbing, I wonder if they got the idea from Charles Darwin!

I was hoping to find an explanation of the connection between the macro-view of entropy (Q(1/T1 - 1/T2) and the micro-view of it with Boltzman's constant. Have you done that elsewhere?

There is a very good video by Physics Explained on the Ultraviolet Catastrophe with the mathematics behind it. It shows how much of a genius Max Planck was by changing the formula from integral to sum in short terms.

Kathy, I enjoy your channel and it's dive into the personal history of physics! P.S. Who is the artist of the oil painting in many vids? Ridling? Riding? I'm trying to find this and other examples from his or her portfolio. Thanks

Please make video on history computer in depth knowledge and Alan Turing scientist

Planck: My wife calls me 'uncle.' Einstein: My wife is nowhere near when I'm with my cousin.

This channel is so underknown

Great. Keep it up. Osho

This is a nice summary about Max Planck, you got one minor detail wrong. Max Planck was born in Kiel, yes he died in Göttingen. (Sorry for being a smart ass, but I am also a German engineer)

Planck was a great composer. Are any of his works still around? His home was destroyed by allied bombing. Would love to hear Planck's piano works.

Can you please do a video on Mileva Einstein-Maric? Did she ever get any credit on Einstein’s papers?

Please do Sommerfeld and Pauli. They are underrated.

My mother got her undergraduate degree I music in about 1930. They had to take a class on the theory of sound. It was based on Helmholtz. Same guy? Music students + Helmholtz! They hated it.🤣

Hey Kathy, is Helmholtz the same guy that subwoofer ports are tuned to? Secondly, is Wien the guy the oscillator feedback bridge is named after? If so, I'd love to see videos about them in the fall! Love your videos!

Wait!! But he was born in 23 April 1858 in kiel , Germany. You are wrong.

The history of physics is so interesting. 😎

Seems like the scientists were so busy with their theories they ended up having relationships with close relatives. This is also know as relativity. 😬

Galileo's Musical Mathematical Measurement timing-spacing realization was a wave-packaging formation, which should be why Newton demonstrated the superposition of frequencies of light using two wedges of glass to separate corpuscular envelopment alignments and reconnect them. But this is a product of hindsight, Planck and Einstein had to rethink it. Given that the ancient knowledge of Eternity-now Perspective positioning here-now-forever is available to everyone, continuously, it seems like active avoidance not to deduce QM-TIME Completeness Actuality from all the work of Sciencing done down the centuries. This is why we've reached "Critical Mass", where if we explain the Vacuum as hyperfluid and hyper-hypo superposition at multiphase-locked resonance to uncluttered minds, ..can we save the planet from impenetrable denialism?

I think the best way to teach physics to teenagers , is by using this kind of storytelling.

Sources?

I see Marie Curie has also attended the Solvay Conference.

It is weird that all of the things described in here happened when kings/emperors and military generals prepared to kill each other. And used their findings to create weapons to kill each other

Could you possibly do a deep dive on Vera Rubin? 😍😍😍

"Nernst started talking with a wealthy soda magnate named Ernst Solvay..." I thought, as other might, that Solvay made drinking sodas. Solvay actually "developed the ammonia-soda process for the manufacturing of soda ash (anhydrous sodium carbonate) from brine (as a source of sodium chloride) and limestone (as a source of calcium carbonate). The process was an improvement over the earlier Leblanc process." (Per

I made a discovery while watching this. Jan 26, 2022 E=hv is square. More to come when I publish...
