As the man said after the Eagle landed: “You got a bunch of guys about to turn blue. We’re breathing again. Thanks a lot.”
The James Webb Space Telescope, largely designed, built, and tested at Space Park in Redondo Beach, has launched, raised itself from the spacecraft, deployed its 5 layer sunshield, and put its primary and secondary mirrors into place. It will take another few months for the telescope to cool in the shade and then to commission the instruments before science measurements can begin.
It has been a long and contentious wait but the magnitude of this accomplishment is worth celebrating.
Playing the piano is damnably hard. I have accepted that I will never practice consistently or wisely enough to reach my original wildly unrealistic goals of competence and am contenting myself with slow progress and occasional discoveries. Coaxing a good sound requires talent, coordination, flexibility, and freedom of movement. There’s nothing that can be done about the first item but occasionally something in the joints unsticks enabling a small improvement in the rest. I feel kinship with weekend athletes who get that occasional moment of grace amid hours of futility.
One of the many frustrations is pressing a key in the same place with the same pressure five times in a row and hearing no sound two of those times. The hammer misses the strings by a fraction of a millimeter and flops back with a click and a dull thud. This makes any kind of phrasing next to impossible for the duffer. He either settles for good enough or goes nuts trying to adapt as the instrument itself changes with the time of day and the weather. It never bothers the professionals who figure it out on the fly.
The piano action itself is a bizarre marvel of wood, felt, physics, and prayer. It is surprising that it works at all and there are eighty eight of the bloody things that have to work consistently. It is a lot to ask, perhaps too much. Robert Grijalva of the University of Michigan explains it in painstaking detail using a model of his own invention. For those with less time, a Dutch animator posting as Hoe Ishetmoegelijk (hoe is het moegelijk = how is it possible) has a concise summary.
Silicon Valley has reshaped the earth, Hollywood has driven our perceptions of it, and not always for the better. Less well known is the outsized role California has played in understandingour universe. Mt. Wilson, Mt. Palomar, and their astronomers have had a Copernican impact on where we stand in the grand scheme of things. The word ‘vision’ gets bandied about a lot these days but George Ellery Hale had it in spades. Here’s how the two observatories that housed Hubble, Humason, Shapley, Zwicky, Baade, Rubin, and Schmidt came to be.
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.
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.
Modern ejumacation has gone multimedia and Powerpoint, often multimedia within Powerpoint. Some like 3Blue1Brown are brilliant at it (the multimedia, not Powepoint), others less so. Here’s a random assortment of lectures where good old chalk and boards prevail: E&M from IIT Madras, chemistry and cryptography from Ruhr Universität, Bochum, Fields Medalist Cédric Villani on something-or-the-other, and an early calm-for-him presentation by Jens Fehlau on the Leibniz integration rule made famous by Feynman. Finally, a tribute to a popular chalk, recently discontinued.
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.
Page 1 of TRW’s Hybrid Engine patent, submitted on 17 March 1969 and issued 2 March 1971 (Click to enlarge)
It has been fifty years since a group of engineers submitted what would become United States Patent 3566717. Entitled “Power train using multiple power sources,”Baruch Berman, George Gelb, Neil Richardson, and Tsih Wang of then-TRW in still Redondo Beach described the hybrid gas/electric vehicle. As a satisfied Prius owner since 2012 and likely repeat customer, I only recently learned that the core engine technology was invented a mile from my house and possibly yards from my office.
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.
