You missed one of the coolest aspects of the raid that rescued Planck... One of the members of that team was a middle aged man named Gerard Kuiper. The father of modern planetary science... "Kuiper Belt" is named after this guy who risked everything to save an icon of science.

[@patrickf.4440]

I had to look around for confirmation of this and finally found it in an old Scientific American article. I taught college astronomy for 27 years and did not know this about Kuiper. It is strange and a darn shame that Kuiper's Wikipedia entry not only neglects to mention his saving Planck but his military service as well. Thanks for bringing this to our attention.

Thank you for all of your efforts regarding the history of Max Planck. Hearing you retell Lise Meitner’s and Otto Frisch’s famous stroll when they collectively realized that uranium atoms were fissioning and releasing tremendous amounts of energy. It is so sad that she did not receive a Nobel Prize for all of her brilliant work. She and Marie Curie are two of my heroes from the early days of nuclear physics and chemistry. Was so happy when they named a new element in her honor - Meitnerium. Please keep your videos coming. They’re truly informative and enjoyable!

A little beside the greatly told story - I can’t rid myself from the feeling that we are in a somewhat analogous time frame today. Other countries, regions and people, but as humans we are increasingly polarized now, than just ten or twenty years ago. More specifically, the ‘08 crisis, the pandemic coupled with increasing social differences, troubled logistics and inflation, racial slur - How are our scientists feeling around the climate challenges and an economy favorable to giant financial powers? The top series on Netflix depicts just that. Are we in a 1918 to 1938 timeframe now? Greetings from 🇳🇴

[@milantrcka121]

I was just thinking about some contemporary parallels within. I am old enough to have seen and remember the cold war and "socialism" goings-on in eastern Europe. Very disturbing.

[@musiqtee]

@@milantrcka121 Yep, I’m 56 myself. Point is, the “socialism” of the Soviet influenced world was a totalitarian non-democratic model - even branding itself as communism. We in the West (myself included) fell for the heavy propaganda, and learned to deeply hate the words themselves. We didn’t learn much about what socialism really means. Of course life was hard for so many ordinary people in Eastern Europe. We should remember that any societal model based on pure power without any democratic influence, is neither liberalism nor socialism - just dictatorship with a fancy name. Taken too far, any -ism destroys society from within.

[@musiqtee]

@@demef758 Empirical insights stand for what they are. Our ability to think critically around those is a personal responsibility. Therein lie the opportunity to reveal other and unacceptable motives behind politics and macroeconomy. So, I agree that corporate powers greenwash for profit, but not with your general standpoint. Harshness will alienate the opposing power, so “being morally right” won’t cut it, just empower hostility.

As a stamp collector I bought at auction a lot which contained a small envelop with a black border addressed to Robert Millikan at Caltech in Pasadena and franked with a common German stamp of the 1940s. The return address on the back said Planck...Gottingen and the timestamp was a week or so after Max Planck's death. So it was evidently the mourning cover that contained the notice of Planck's death. I called the archivist at Caltech and he said he had the notice that was enclosed in the envelop and I wound up donating it to Caltech along with several other covers addressed to Millikan.

Hi Kathy, I have watched a number of your videos over time and find many of them fascinating. Especially many of your ones on electricity and other sciences. This one, especially, struck a chord as my Grandmother, Ilse Rosenthal-Schneider, was a student of Einstein at Berlin University as well as corresponding with him, Max von Laue, Max Plank and lise Meitner until their deaths. I have in my posession a fair bit of correspondence between each of them and her, including ones from Einsten and von Laue, congratulating her on my birth in 1952. Most I have copies of, but the one from Einstein I have the original letter. Most of the other originals were delivered to the Jewish Museum in Israel by my mother in the '90s. after my grandmother's death. Unfortunately, not all the letters survive as in her last years she decided to destroy some of them due to their perceived political connotations. She also published a book in 1980 entitled "Reality and Scientific Truth : Discussions with Einstein, von Laue, and Planck" My grandparents and mother (who was 15 at the time, left Germany in 1937), arriving in Australia in 1938. My Grandfather was Jewish and my Grandmother Lutheren. They managed to leave with all their possessions in two liftvans, basically containers but made of wood, some of which I have to this day, and ended up in Sydney, Australia.
