Heisenberg, Bohr: the Friendship behind the Copenhagen Interpretation of Quantum Theory

The Copenhagen Interpretation was born of the friendship between Werner Heisenberg and Niels Bohr. How did they meet, how did their friendship change science and how did the outside world damage that friendship? Watch this video and find out!

I found the Copenhagen interpretation very fascinating, however I had no idea the history behind it. Amazing video!

Cool video. I study at the Niels Bohr institute in Copenhagen. And have my experimental setup in the very old building where many of these ideas were made. Niels Bohrs office and the old auditorium A remains unchanged to this day.

Loved your video, as usual! As a physicist myself, I always felt like I didn't know anything about the human history of my own field. So I am grateful for videos like yours.

Kathy, I am blown away with your passionate storytelling about Bohr etc. They inspire me and help me understand the importance of relationships behind the scientific discoveries - I love it. Very original and riveting.

This channel is an absolute treasure. Glad you have found it! 👏

I love the exposure of the interplay between the characters involved. When you beat your head over lines in a cold stolid text book and feel stupid for not seeing it as so easy - it is nice to see that the formulation wasn't so easy in the first place.

I have no idea if it has been translated to English, but there's a great book in Danish: Det Udelelige ("The Undividable") describing this amazing period in physics that people still struggle to understand this day and age

After some extra reading on Wikipedia I found something curious that was unknown to me - one of Max Born's grandchildren is Olivia Newton-John, i.e. Sandy from Grease! (among other things)

Thank you for filling in so much of Bohr's personal history. I always respected him as a physicist, but was unaware of his heroism during WWII.

I find the personalities behind the science very interesting and you cover that topic as well as can be done in 15 minutes. Who are these people who can come up with such extraordinary scientific advances in a time when the horse was still a major form of transport.

Excellent story, of how politics changes the curiosity of people and turns them into weapon making ideologues. This should be made into a documentary! Thank you for the lesson.

[PhilMoskowitz]

I think it might add a little more to the story if you also discussed Einstein and Heisenberg's disagreements on the inclusion of only "Observables" in a theory. In it, Heisenberg lays one of greatest burns in science history.

Absolutely stunning! I just started digging deeper into QM and this vid added so much meaning and fun to those theories. This is just awesome, keep up the good work!😄💎👌👌

I can’t believe I just found out this wonderful channel! Outstanding work, I have spent a lot of time to connect science and history out of personal curiosity and interest, so glad to find someone with this passion and goal. You should be proud of your work Kathy 👏👏👏 absolutely inspiring summary you put together here.

It's not "Lip-sig", it's more like "Lype-sig". Otherwise - a subject that always fascinated me! Thanks!

Max Born was the grandfather of Olivia Newton John, and both Olivia and Albert Einstein visited Born's house often. Olivia's (and Einstein's) approaches were "Let's Get Physical, " while Born's (and Heisenberg's) approach was "Let's Get Quantum."

Kathy, I love you’re videos!! It would be great if someone (hint) published a YouTube video each week entitled “One Hundred Years Ago This Week in Quantum Mechanics.” It would help slow learners like me. 😊

[renzostefanmp]

Keep it up please, you have a beautiful way of tell these stories! You deserver a lot of subscribers.

Very interesting narration, great job, but I missed a must mention of Louis de Broglie when it comes to the period of 1921-1930. Very nice presentation of historical accounts along with conceptual milestones
Gratitude
Best

Kathy, I love your videos. You have great enthusiasm for your topics! Your explanations link to the "why" of the names we had to learn!
