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.
I’ve owned and/or used many toasters and toaster ovens. All have been crap. It doesn’t matter how much it costs, it all comes from some noname as cheap as possible factory, doesn’t work as advertised, and falls apart quickly after making marginal at best toast. Paying for quality is no longer an option. Alec from Technology Connections profiles a 1948 Sunbeam classic that still works due to a brilliant, timeless design. His channel and Techmoan both delve deeply into our electromechanical past finding, explaining, and often resurrecting devices we’ve forgotten.
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.)
Baseballs are one-and-done, discarded after even the merest nick or scrape. Cricket balls are used continuously and degrade progressively after countless bounces off the pitch and strokes of the bat. Fast bowlers start off with the new ball giving way to medium pacers and finally the slow bowlers take over when the damage has been done and make the ball dance. Crafting the classic red balls for Test Matches is a fascinating blend of art and manufacture – Dilip Jajodia explains.
In those seven years of hybrid ownership, I’ve often wondered what actually goes on under the hood. Niels Blaauw offers a charming overview of older implementations of the engine and drivetrain. Next, Professor John Kelly of Weber State University dives deeply into the innards of the transaxle that’s in my generation of Prius. His WeberAuto channel is a gearhead’s goldmine.
We have megapixel cameras in our phones and gigapixel cameras on our telescopes. Before digital took over photography (and the world,) we had film. Light struck silver and made a mark and behind it all was some marvelous physical chemistry. It is still awe-inspiring to think of how these processes came about when knowledge and instrumentation were not nearly as advanced as today. Each step could have millions of alternatives and sorting them through brute force would take the age of the universe. Yet somehow it all came together and spawned industries. The American Chemical Society takes us through the science as it was in 1940.
The Event Horizon Telescope team announces its major discovery following two intense and quiet years of data analysis on top of a longer period of development. A nice testament to aperture synthesis and international collaboration as the rest of the world spirals into madness. Damn!!!
We routinely use ultrasonic cleaners to decontaminate all kinds of surfaces. A little solvent, some buzzing, and jewelry, electronic parts, and pen nibs get degunked effectively. Cavitation is responsible. It is also responsible for damaging surfaces such as ship propellers and pump impellers. The first video explains the physical chemistry behind the process and its (mostly) destructive effects. The second shows it applied to cleaning vegetables which, surprisingly, is a research problem funded by the National Science Foundation. Both videos show closeups of bubble collapse making the cleaning/damage mechanism much easier to understand.
