  • This guy is awesome, great video. Anyone know more about him?

  • He is my grandfather. He was a professor of physics at Michigan State University and, later, at RPI. He earned his PhD from Yale in 1948, after immigrating from Austria during World War II.

  • No offence intended, but is he still alive? If so, I hope you tell him how interesting everyone finds these videos.

  • Yes, he is. His youtube username is: ale86itn.

  • This is amazing to watch. It's great learning about this subject, but I have to say that I love the feel of it all....the simple black and white photography, the very practical editing, the voice of the narrator. He is a very good speaker. Very clear, and captivating. An artifact from another time, yet still very relevant today.

  • Mind blowing facts. Why isn't this shown in grade school? I believe it would compel a child's mind into pursuing education to its limits and push knowledge further. Instead, it's Jersey Shore and American Idol. We are ignorant dolts! This is amazing work. Thank You for uploading this.

  • Wow ... Unreal!

  • Your grandfather is a great teacher.Thanks Alfred!!

  • why couldn't it?

  • F00L

  • Nothing short or miraculous, Helium II allows us to see the quantum concept of uncertainty at a naked eye, non atomic level. A real life Schrodinger cat :)

  • no friction. Which means it if sped up, it could possibly exceed the speed of light

  • well... you see. He summed it up in the very end but in even simpler terms.

    Superfluid is a sentient being that can pat its head while rubbing is tummy

  • i have watched all the series ... can someone please sum up all the most important expressed in here ??
