Crystals - Alan Holden 1958

[@scienceotherside2000]

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

Fascinating video. For those dying to hear all the instances of "Alum" by Mr.Holden, here are the time stamps. 01 - 1:37 02 - 1:48 03 - 2:47 04 - 2:59 05 - 3:00 06 - 9:47 07 - 11:42 08 - 16:30 09 - 16:37 10 - 16:50 11 - 17:39 12 - 18:09 13 - 22:41 14 - 23:11 15 - 23:14

Whew!!! Some list!

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 surprisingly, this documentary is a gem.

The older generation was way smarter than the present. These guys were smart and multitalented.

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.... This is science!

Captivating and brilliant. Thank you!

Fabulous! Keep uploading such extraordinary experiments.

Where are these film notes

[@jameswelch5636]

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

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.

I love it

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.

Some expert, didn't once mention crystals' healing and protective powers. /S
