Simon Ramo explains Cloud Computing

The ‘R’ behind the Thompson-Ramo-Woolridge (later TRW) corporation passed away a few months ago at age 103. Simon Ramo saw the future and made a lot of it happen in a bygone era when technical people ran corporations. Here, he explains what we currently call Cloud Computing over a lovely guitar score by Nell Hultgren of whom little, unfortunately, can be found.

Fly US to the Moon: von Braun vs. Houbolt

To this day, the questionable Wernher von Braun gets credit for most American space accomplishments of the 1950s and 1960s. He tirelessly aimed at the stars (with the occasional drops on London) but engineering realities were at odds with his grandiose plans and even grandioser rockets. John Houbolt’s Lunar Orbit Rendezvous approach eventually won out and his role in Apollo’s success is insufficiently known. Here’s a comparison.

Ledes of lead

The International Printing Museum in Carson showed (and, hopefully, still does show) visitors a working Linotype machine. Inspiring engineering that lasted a century, now surpassed by digital methods that are replaced at much greater frequency.

Distillation: What goes on in those refineries?

Big tankers tie up offshore and disgorge their contents into brightly lit and mostly inscrutable refineries.   This sixty year old film by Shell Oil neatly explains the chemistry, chemical engineering, and physics of distillation that takes gives us our gasoline, diesel, oils, and waxes. In a different setting, it also gives us many different kinds of beverages.

 

Adriaen and Hadrian: Lost Wax bronzes

I had the great fortune of looking out my grad school office window into a sculpture garden of Rodin bronzes.    The lost wax process used to make these marvels keeps eluding me.  Every time I think about it, I forget steps and/or get them mixed up.   These two videos from the Israel Museum and The Getty go a long way to shoring up a sagging memory.

Back to the garden: So, did we chemists appreciate what we had in front of our eyes? Yes, quite a bit. The program was stressful and we’d wonder darkly whether we were on the wrong side of the Gates of Hell while having lunch in front of it. The fate of an adjacent parking lot stirred a lot of debate between a supportive faction of chemistry faculty, staff, and students and the late Prof. Albert Elsen of the Art History Department, eminent Rodin scholar, and advisor to the Cantor Foundation that donated the works. The Loma Prieta earthquake intervened and gave us all other things to worry about. The statues don’t look any worse for wear decades later despite fears that they’d dissolve into nothing. Careful stewardship and loving cleaning, enabled by a little chemistry, have served them well.

It is now official, humankind has put its toe into interstellar space as Voyager 1 crossed into the heliopause nearly a year ago. This milestone has been hotly debated in the scientific literature as heavyweight teams presented evidence pro and con. It was only in the last few weeks, however, all parties have agreed on what the data from the probe mean. And they agree that it is now past the interface between the solar wind and the great beyond.
