ANW’s tribute to myth, art, and engineering is both visually dazzling and a chutzponic choice for this temporary breather from the pandemic. Water is everywhere – onstage and on the audience – as a gifted cast seamlessly weaves eight stories and a coda from Ovid to impressive stagecraft. The play is sufficiently well-known that there’s no point in recapping the fables-for-grownups by Mary Zimmerman, a brand unto herself. Locally, Stephen Legawiec’s long-departed and much lamented Ziggurat Theatre Ensemble did exceptional service to myth. The Sacred Fools and Coeurage also deliver technical miracles on a budget. Zimmerman ups the ante requiring an onstage pool central to her theme. ANW has built the resources over the years to afford the rights, the engineering, and the resident ensemble to pull it all off. The costs must be astronomical especially for a barely four week run, an oddly appropriate leap-of-faith in art over economics.
On top of the usual artistic concerns and choices, director Julia Rodriguez-Elliott has to see to the safety of her performers who are feet, knees, and backs in the water as much as they are out of it. This is no mean feat given costumes (Garry Lennon), props (Shen Heckel), walking continuously on a wet stage, and a disease spread by droplets. The company has hewn to its resident artist model (six of the nine performers) although it seems to have gone away from its roots in repertory. It is interesting to note the changing of the guard having followed the company closely in the 90s to mid 2000s and sporadically thereafter. Geoff Elliott remains a constant of the motion with Rafael Goldstein and Erika Soto now regular members along with unfamiliar faces with extensive company and classical credits. That Shakesperean training pays off handsomely with uniformly rich, resonant, and nuanced voices inhabiting instead of reciting the text. It’s a heady mix of comedy, drama, pathos, and bathos. Trisha Miller is excellent as Alcyone, Sydney A. Mason as a nasty Aphrodite, and DeJuan Christopher as Ceyx. Elliott is all the fathers; Pythonesque as Helios negotiating with Phaeton (Kasey Mahaffy) as well as Midas and Cinyras navigating daughter problems. The physical demands are great as the cast have to carry one another in and out of the water throughout the piece where one slip could end many careers. The level of trust engendered by long and close collaboration must be off the charts and hard to conceive with a team assembled for one production.
But, oh, that engineering – Francois-Pierre Couture (design), Ken Booth (lighting), and Robert Oriol (sound) – deserves a loud, two-syllable, “Damn!” Even if we take the pool for granted, electricity, water, and people don’t mix. This constrains the high powered lights to surround the stage and there again from safe a distance – yet nothing essential is in shadow. Glowing orbs are undoubtedly enabled by LEDs. Their collective play off the water and onto the walls are a splendid touch – carrying the audience along waves of action floating on Oriol’s effective yet unobtrusive soundscape. And we should not take any of this for granted. Going from page to stage is a tough artistic job but no easier than taking a technical concept through design, build, test, and delivery. ANW’s timelapse shows the large uncredited crew that made it happen and glimpses the kind of backstage preparation area accessible to very few of the city’s theatremakers. Yes, there are a couple of songs but … what are you going to do? Barring extension, only five performances remain so act accordingly.
Note bene: While there are no bad seats at ANW, the raised stage does obscure the water’s surface from the front rows. There is a benefit (and certainly no harm) in going to the middle or even the back of the house. Those up front will get splashed.

Sports Illustrated quoted this Japanese proverb back in 1975 in conjunction with Cal’s championship men’s gymnastic team of that era. The adage abides with the James Webb Space Telescope now in its halo orbit around the Sun-Earth L2 point, its optics and instruments slowly cooling to their ultimate cryogenic temperatures, the better to collect the faint signs of heat from the early universe. Little has been said to the public about the instruments nestled in the big box behind the 6.5-m primary mirror. This is perhaps not surprising. There are no secrets here, just that the real science goals and the optical engineering to meet them are fiendishly complex. Friendly Neighborhood Astronomer Christian Ready tackles the challenge, explaining where the precious photons will go and what will happen to them once they arrive. The comment section clamors for more detail on the MIRI cryocooler which will take the mid-Infrared Instrument’s focal plane array below 7K. Here’s to hoping for a full video on this beast, built across the hall from me, and on which I spent a couple of weeks when the team was shorthanded.

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.

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.

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.

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.

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.

Addendum 25 September 2020: EPFL has reorganized its webpages and the cavitation videos have disappeared. Here is an American Physical Society report on that research.

Our society depends on standards in countless, mostly invisible ways. If we can’t agree on how to measure weight, length, temperature, or time we can kiss manufacturing and our manufactured world with its specified, engineered, and interchangeable parts goodbye. Actually creating and maintaining these standards is hard and the methods change over the years. The meter was once defined in relation to earthly distances until the realization that the earth changes over time. Now it is defined in relation to the speed of light which we are pretty sure does not. The second used to be defined in terms of the day, now it is based on a fundamental property of the cesium atom. The kilogram has just been redefined in terms of Planck’s constant which then turns into a combination of the second and the meter.
Making any of these measurements is difficult and requires a lot of fancy equipment, often involving lasers, vacuum chambers, electromagnets, and/or racks of electronics. Here’s how NIST’s new F2 atomic clock works schematically and here’s a package from its inventor on the details. As the F2 becomes a practical albeit sophisticated standard, even fancier methods are under development for the future.
The Kelvin, fundamental unit of temperature, is a nice exception to this complexity. It is defined in relation to the triple point of water; that temperature at which the liquid, solid, and vapor phases of isotopically controlled, gas and contaminant-free water are in equilibrium. Measure this and the Kelvin is 1/273.16 of that. The aptly named triple point cell requires appropriate water, a skilled glassblower, and some patience. Thermometers can be calibrated against this standard within and across laboratories.
The Fluke Corporation, despite its name, has long been a respected supplier of a wide variety of test and measurement equipment and they sell such a triple point cell. In the right hands, it can allow the temperature of 0.01C (the Centigrade and Kelvin are equivalent) to be measured with an uncertainty better than ± 0.0001 °C. Here’s Fluke’s Matt Newman showing how it is done and not a laser to be seen.
Addendum 20 February 2019: The Kelvin has also been redefined as of November 2018. It is now tied to Boltzmann’s constant, k. NIST says that not much will change for the moment since the triple point cell is a known, reliable tool.
From back in the day when cars had teeth: An assortment of dental excellence from El Segundo’s marvelous Automobile Driving Museum. It looks like a showcase of lovingly restored and superbly maintained American cars and it is all that. And the side of fries? Machines are meant to be used and on Sundays, they take a rotating subset onto the roads and let the public ride along.
I went in not knowing that the museum was actually closed for a private party but no one said anything and I browsed the collection at leisure. When I go back – and I will – I look forward to opening doors, sitting in the seats, and enjoying the insides of these artefacts of a bygone era. That’s also allowed and encouraged.
