The third video from Corning’s Museum of Glass shows that the path to science is not always smooth and that learning from mistakes is the norm. The original 200 inch pyrex disk for the Palomar primary did not go according to plan and had to be recast. The second attempt succeeded and even so, it took ten years of painstaking grinding and polishing at Caltech before it was ready for use.
The web’s archive of older industrial films is a recurring delight. Jam Handy, Coronet, and other firms crafted these with an attention to detail, calm explanation, and rigorous science that is harder(*) to find today when most equivalents are about sales rather than fundamentals. Jeff Quitney has uploaded a wonderful 1954 cleaned-up film to his Vimeo page on color theory and practice by the Interchemical Corporation. It begins with the importance of color to society – especially in packaging goods and people – and then gives a marvelous account of the optics involved. I’ve worked in the field for years but I learned to see things (pun intended) differently thanks to it.
The second film from 2016 looks at color in packaging through its emotional impact and its influence on design and designers. ‘Color In Sight’ resembles like Hustwit’s ‘Helvetica.’ A number of prominent designers talk about how they use and think about color in order to evoke a response, surface a memory, or reveal a part of the spectrum to the color-blind. I have no idea what I’d say to a nail-polish maker but Suzi Weiss-Fischmann (8m18s in) comes off as a fun seatmate on a long plane trip. I had a similar feeling about Helvetica’s Paula Scher. Interestingly, it is produced by TeaLeaves, a Canadian company specializing in very high-end teas for hotels. Judging by their Youtube page, they must spend a fortune on short films – many of which have little outward bearing on their products. I’ve never understood the appeal of tea but the videos are well worth a look.
The mere detection of gravitational waves two years ago was cause for celebration and, for those of us skeptical of LIGO, eating of crow. Now gravitational wave detections regularly cue electromagnetic observatories on the ground and in space with tighter integration to come.
Youtuber skydivephil puts the camera on several researchers active in developing the next generation GW systems and the ever more ambitious cosmological probing that these observatories will enable.
Skydivephil and the unnamed narrator are self-effacing providing few details about themselves, not even their names in the nonexistent credits. They also have enviable access to many leading physicists and institutes, largely on the theoretical side. The style is simple: Let the speaker speak. It is a refreshing antidote to the modern space documentary which highlights the doom-and-gloom with an explosion and visual effect every fifteen seconds. Whatever one may think about string theory, loop quantum gravity, or their alternatives, it is refreshing to hear about them from the purveyors. Here’s the “Before the Big Bang” playlist with an assortment of views on modern cosmology (note that the episodes are in reverse chronological order.)
At one time there were several Youtube channels that found, cleaned-up, and uploaded public domain training films and other documentary-style educational videos for a grateful audience. wdtvlive42 and Historia-Bel99TV were summarily deleted a couple of years ago. This week the hammer fell on Jeff Quitney who had presented over five thousand films that he had spruced up. Youtube does not seem to have an appeals process. They first demonetized him based on (most likely spurious) copyright claims against music that was part of a few of the soundtracks. Now, his channel has just disappeared. Fortunately he has at least partial backups at Bit.Tube and Vimeo. His goal is to ultimately have everything restored but that will take considerable time. I’ve linked to him many times and have found at least temporary replacements from the Internet Archive as well as from other Youtubers. Still, it is a shame what happened to him.
Periscope Film of Los Angeles still exists, providing watermarked films from their commercial library. Let’s hope they remain and grow.
Addendum 7 April 2019: Looks like he’s making Vimeo his go-to site for old and new videos. Click the image to go to his Vimeo page.

As time marches relentlessly on, it slowly erodes what you think you know – especially those things you never knew in the first place. Despite all of its cruft, marketeering, and self-promotion there’s still a small corner of the internet that hews to its educational roots. The structure of subatomic particles like protons and neutrons is not conceptually easy, the mathematics reserved for a few. Eugene Khutoryansky’s colorful and surreal videos do a great service in making abstract concepts concrete. The underlying classical music soundtrack is in subtle contrast to the extremely non-classical physics.
Integrated electronics make us forget about them. Tiny packages with millions of transistors encapsulate so many functions so effectively that we don’t or can’t know what all they do. This is a boon to manufacturers since repairing anything is all but impossible. In the not-too-distant past, these functions or a small subset of them, had to be implemented in metal. Techmoan does a stellar job of rediscovering old technology. Prof. Bill Hammack of UIUC is also a master of this. Here he explains how the whiffletree mechanism enabled the IBM Selectric typewriter to work its magic. Beware – it is easy to lose a day watching his other videos and searching on the nuggets he finds.
These videos provide excellent overviews of proteins and enzymes – what they are and why they are important. They are produced by the Research Collaboratory for Structural Bioinformatics (RCSB), a part of the worldwide Protein Data Bank Archive. The RCSB site has additional educational information for non-specialists through its PDB-101 subdomain including curricula for teachers, video challenges for high school students, and a “molecule of the month” providing interactive views into complex protein structures.
