Usually I’m not a fan of presentations on science history. Not because the history isn’t interesting but because there is repetition of that history ad nauseum. I often skip over the first half of many science videos. In contrast this was novel and fascinating from beginning to end. Thank you.

Funniest Tee shirt I ever saw. Late eighties or early nineties. Carsberg had an advertising campaign : "Probably the best lager in the World", and it had a very distinctive font if you saw it in writing. One day I was strolling through a park and a young guy walked by; on his tee shirt was written in that same distinctive font: "Heisenberg: Probably the Best uncertainty principle in the World"

In my University days, we used to call Carlsberg the 'Quantum Mechanics Beer' 😂😂

I am so happy you made this short video. It would be hard to learn all of this anyplace else. Thank you.

A couple of decades ago, as a biology student I participated in a cross-disciplinary seminar on science theory with <s>among others</s> physics students at the Niels Bohr Institute.<br>Knowing what Bohr had accomplished in the early 20th century and the history of the institute, it was awesome wandering the corridors and entering rooms with blackboards that had been filled with chalk formulas by a dozen of the real giants of science 80 years earlier.

You know Carlsberg is a very much Revere beer in Hongkong to this day, just that I'm not sure they are drinking to the legend of quantum mechanics. Beer certainly sells better than the spooky stuff. A captivating video toasting to Carlsberg , Heisenberg and Bohr.<br>Thanks for the effort and keep up the good work.

I'll try and get in first here, before anyone else! 🤭 because all we can probably say about what Heisenberg really said to Bohr in Copenhagen, was that there is an uncertainty in the future of theoretical physics, but it refreshes the parts other beers can not reach. 🍻🤨

Great video, Prof. Al-Khalili, excellent conversation; being the archivist in just a legendary place must be a joy. Bohr's Institute is one of the places that I hope to visit one day.
