Alfred Leitner, is that you? If *yes*, I just have no words. Were were brought up by these vids on our quantum physics lectures in Moscow Institute of Physics and Technology, and now I can say "thanks". Thanks for those great vids and that spirit of western science that encouraged our interest in science and prevented us from sleeping during the lectures :)
@DonXenapo Yes, this was my grandfather's account. He has since passed away. Thank you for your kind words. I'm certain he would have appreciated them greatly. He spent his final years just astounded by the revived interest in his films, since we posted them on YouTube. Google his name and you will find his website.
I wonder how frequently Latner was assaulted in the street due to his spooky resemblance to a particular leader of the National Socialist German Workers Party..
Currently a college student, having loved science all my life, I wonder why it is that science has become such a novelty. This right here is mind blowing stuff! A fluid that defies it's own gravity?! "He2" literally broke the rules of fluid behavior at the time. That was 50+ years ago, and people are amazed more now by getting their inefficient cars to burn less gas and to be quiet. Maybe there isn't much left to discover, but I do hope to be in a video as full of awe as this someday.
I don't understand why it's Liquid Helium II? Can someone explain, and is the theory behind superluidity of He II much different then the theory behind the superfluidity of He IIII >
This is fascinating. I must show this to my friends and family. Should also show it to my science teachers, I think they'll love it. Thank you for putting this up.
Oh, well I guess he also uses the archaic "degrees kelvin", rather than saying "kelvins" as it became after SI made it an official measurement quantity of absolute temperature. But still, it is striking how there is no difference between 1963 and 2010 in their understanding of the science. Compare that to how incomprehensible this would have been to someone in the year 1800. They didn't even know there was an absolute zero then. Or maybe they barely knew it by about then.
I would not say that science didn't advance much. In the 1960 it was said that "He who has studied quantum physics, and found it comprehendable. Has not studied it well enough". Now they are teaching it to first year physics students and expect them to understand it. Also our knowlegde of the structure of the cell and DNA has grown immensly.
But I do agree, I don't think we've had any Einsteins or Plancks in a while.
@rutger5000 I disagree. We don't have fusion power or super-cheap solar power. We don't have artificial intelligence that is smart enough to tell the difference between a shadow and a hole in the floor. We don't have cheap interstellar flight. We don't have a grand unification theory of physics. We don't have room temperature superconductors. We haven't conquered cancer, or even figured out what aging is. The biggest thing we have to say for ourselves now, 50 years later, is cheaper transistors.
@rutger5000 and it's not just that. Much of the stagnation is DELIBERATE. We COULD have redesigned our automobile industry to use electric cars but we chose not to because higher maintenance cars are more profitable. Look up the streetcar and the EV-1. Killed by the auto industry because they threatened their profit potential. And as many people in first world countries believe in creationism and as many oppose the teaching of evolution and fight to push religion into public schools as ever.
Well now we're getting into a difficult discusion. You're saying sience didn't much advance, and I'm saying it did. It's a matter of opinion. I think most people don't hear much about new scientific breakthroughs, because sience is now so far from the common man. Through scientific breakthroughs, just can't be comprehended anymore, unless you're an expert on the subject. As for your other comment. Yes people are stupid and greedy. They always were, and they always will.
What a great video! The best part is that after almost 50 years, the only update that could be made is that a lambda point was eventually discovered for the isotope helium 3 (in 2002 I think I heard about it) - and it's less than 1 millikelvin. But everything else he said and did was so timeless, I can't imagine anyone could possibly make a video more thorough and clear 100 or 1000 years from now. I looked up Alfred Leitner and couldn't find much. Is he still alive?
@Oxstayne This movie was made in 1063. At that time our lab was still using the old Linde air liquefying machine. The delivery of Liquid Nitrogen by truck was just about becoming available around that time.
who posted these videos? Do you still reply?

I wish there where more videos out there that is so concrete and so "right on"!

That double dewer looks very difficult and rather expensive to make. I wondered if it costed a fortune to buy in those days

1963 ! I heard about superfluidity a week ago ! So after almost 50 years they should be very deep into the subject.
