Very interesting video! So many important discoveries in those years, sadly the wars had their influence on the scientific community.
About the Auger effect, it doesn't seem to have been misattributed to Auger instead of Lise Meitner. In fact, she even used the term Auger effect in 1926. You can find a discussion of this in Pierre Auger - Lise Meitner: Comparative contributions to the Auger effect, published in the _International Journal of Materials Research_ (formerly _Zeitschrift fuer Metallkunde_ ) in 2009. You can find it on RG, but I won't post the link (cf note.
Note: My previous 3 attempts sent an error message when I was trying to correct a typo or some formatting issues and seems to have disappeared when I cancelled the edit. Maybe it was caught by a filter. I tried removing the links at first, then the mention of the RG scientific social network, and finally I had to remove the DOI of the article I'm referring to. Hopefully, said missing comments won't reappear as duplicates of the present one.

Many physicists seem to think that Heisenberg's uncertainty principle is at the heart of the strangeness of quantum mechanics. But, in reality, it only expresses what Jean-Baptiste Joseph Fourier had already explained in comparing measurements in the time domain with measurements in the frequency domain. Just as these two domains are linked through the dependence of frequency with time, the domains of position and momentum are similarly linked (momentum is the derivative of position. The mutual limitation of precision described by Fourier is the same reasoning behind the mutual limitation of precision described by Werner Heisenberg. It is simply a limitation on being able to measure the position and momentum of a particle simultaneously; it is not a claim that either position or momentum ever is lacking a precise value.
So the uncertainty principle is independent of the mysteries of quantum mechanics, only becoming more significant at small scales due to its being easier to observe there.

These are great. I've largely watched topics I am quite familiar with. The accuracy has been super and the presentation clear and interesting.
Real physics, real history, and not over-simplifying into meaninglessness. Thanks for producing something I can share and recommend to curious non-scientists. And 15 or 20 minutes at a time isn't a giant commitment.
These really capture the spirit of some of my favorite layman-accessible pieces of real science in a bite-sized chunk. That's impressive. The kind of things I'm thinking of: Feynman's The Character of Physical Law lecture or Darwin's On the Origin of Species or the old The Strange Story of the Quantum even Feynman's QED. I recommend all of those things, too. But they ask a lot more of the audience.

20 years ago I read The Making of the Atomic Bomb by Richard Rhodes. I was hoping to learn about the science. Instead, the book discussed at length the political and social forces that shaped the scientific landscape that influenced the research and discoveries that resulted in the making and deployment of the bomb and its repercussions.
A fascinating history that I highly recommend.
(Yes, the book did give me the science and technologies of the bomb that I was hoping to get in great measure. Which is why it is 700 pages)
Your many videos revealing the personalities behind the science compliment and embellish what that book started.
Thank You!

Einstein originally saw the curvature of light in terms of an equivalence investigation of a photon with a rate as it was incident to a accelerating box. The result from this was not correct, and was not really the curvature of space time idea he generally made. If there is a 'curvature', or more like difference in spatial dimension from place to place, is your guess if it really exists, but there is some data affirmating time dilation, and gravity waves. It is possible the other forces are the same argument applied to other forces. That is the sort of logic Einstein used in the Photo Electric effect.

If you really want something unbelievable try a step up transformer just using the basic counter and clockwise layers you don't need metal. But you have to layer one coil at a time. when pulsed. the other receives a voltage step up by adding core material amps are also increased. I believe Tesla thought it was to simple to create more from less. . I have tested it 5 volt's in 40 volt's out. I Thank you This is my way of returning the favor. equal length's of wire and same gauge. Thanks. If only we as a world weren't dumbed down by greed. Imagine the wonder's

Thank you for this well-documented and historical objective lecture on history of science.
Max Planck was a genius on the top of a group of geniuses, knowing in advance who was scientifically right, and who wasn't. He was harmonising science and people as consequence.
Lenard was an anomaly in my opinion. He reached the end of his scientific tether, and begun using politics to hide his limits; all of who followed him, attempted to further advance theirs careers by political means, and no longer because of study and research.

Kathy you're wonderful. I started watching one clip abouyt electricity so I could understand better it's usage. Since that I just can't stop! I am not a physicist or anything close to a science buff (I am a welder. But I really enjoy your way of compiling all those figure larger than life who transformed so much of the appreciation of the world we have today. So has the birth of all those theories so vital in all aspect our day to day lives. Thanks!

A well researched account thankyou. describing how a bunch of highly intelligent people got it so very wrong using confirmation bias created the century old religions of relativity and quantum nonsensewhy? (space and time have attributes only, not properties.
The missing secret of light, a wholly induction process, is the dielectric longitudinal pulse component mistaken as so called particle/photon. this destroys Relativity and Quantum)

I'm plowing through many of your videos and enjoying all of them. I've tried reading Heisenberg's original paper on the introduction of matrix mechanics, but I find it pretty incomprehensible. which leaves me pretty depressed because it makes me feel like I'll never understand how quantum mechanics was discovered. I don't suppose you know of any more reader-friendly versions or guides for understanding Heisenberg's work?

Ive known about all of these people through my studies, but not like this! The connections, the relationships, and all of the personal circumstances have such a big part in how thing played out. It makes me wonder what it would have been like if Plank hadnt helped keep German research alive during the difficult years around WWI. You really make it all come to life. Another great video!

Physics history especially around the start of the former century is mind blowing. And Planck besides his overwhelming patriotic spirit. Were worth a Nobel price. But knowing madam Wu couldnt get a price because she was a woman, I guess we dont have to judge it by todays standards. I dont understand they dont give it post humt. Maybe it will come

What is shocking is how intellectuals of great intelligence can believe that they are less affected by propaganda and cultural movements than the average person. Planck was just as enthusiastic for the Great War as was anyone. Bottom line: just because you are smart does not mean that you are right.

I just LOVE the when races were still pure. Bleeech! 5 Kathy, Don't let em' get you down. I'm 70 y. o, fluent in German, and the speeches made by the MAGA right in the US sounded better In the original German. We live in interesting times. (A Chinese curse)

It is deeply moving to have some insight into the tragic struggles face by these giant of physics(and Chemistry. What a shame they had to discover the mysteries of the atom at the same time the world was losing its mind

When i think of Plank, I think of length. It's worse than trying imagine infinity. The last we all know, impossible! But the former? There is no limit in that direction. Well, until you hit infinity again: )
