    I'm an engineer with a great passion for science. Videos and instructors like these are incredibile. Totally on another level.

    Holden's videos are great. His manor of presentation is captivating. I love his statement about cleaving the crystal and calling it a "stunt". This was done I believe to identify with the audience who at the time used the word often. His classes would have been a treat to attend. Lab presentations that aided the understanding of the subject are outstanding. I'm now searching for his videos. Thanks for your thoughtful selections of fabulous lectures.

    I don't know what I expected when I clicked this video. IT's exactly what it said it would be. Thumbs up for no clickbait.

    Not afraid to say I don't know what an atom is! I can only tell you where they are and how they are arranged....

    My Grandfather (1901-1985) at the kitchen table. They're so close, you can see his brain working with his facial expressions. Same and similar mannerisms and colloquialisms. "Granite's a good example, here's a hunk of it." You can tell when they rolled credits, he fired up a Viceroy.

      Currently, there's a transcript if you scroll down a bit after clicking for the description.
      Can't vouch for it's accuracy, however.

    I think the bubble experiment should be conducted in a vacuum... Did he establish a growth rate for alum? I witnessed symmetric exponential growth... Temperature is a factor.
