A talk by  Jensen Huang, founder & CEO of NVDIA, at Stanford.   Very, very good.   Related post and discussion.

Ruxandra Teslo  notes that student protestors in the 1960s wanted less bureaucracy and more freedom…today, most of them seem to want less freedom and more bureaucracy.

It’s not the phones, says Marc Andreessen, referring to the psychological dysfunction that seems to afflict so many of today’s young people.   He’s responding to a post by  Jash Dholani, who says “the young aren’t driving, f******, and drinking because high energy activity is fundamentally incompatible with modern ethics. If you’re always told to be harmless (but also guilty!) then your innate will to power withers. You vegetate. Man, the greatest animal, turned to plant.”

Elon Musk  says:

Many movies exist about a lone inventor in a garage having a eureka moment, but almost none about manufacturing, so it’s underappreciated by the public. Compared to the insane pain of reaching high-volume, positive-margin production, prototypes are a piece of cake.

(Not many such movies,   but one that comes to mind is  Valley of Decision, a 1945 film centered around family-owned steel mill in Pittsburgh.   I reviewed the movie, and the book on which it is based,  here.   Also, there’s Executive Suite, a film from 1954 which involves executive succession at a furniture manufacturer…mentioned in a batch of reviews that I posted  here)

In a comment at an earlier version of this post at Ricochet, Gary McVey noted that

“the eastern Europeans (in other words, the Communists, if not always the Soviets) were pretty good about trying to publicize the drama of start-up, the challenges of production. When we mock those days for films “about a couple falling in love at the tractor factory”, we are mocking something that, if you actually see the films, is in fact objectively a good thing. Some of them, by the Poles, Hungarians, and Czechs, were good. The best of them had little or nothing to do with Marxist theories, just the everyday achievements of construction, engineering, and metalwork that sated Western audiences found dull as dishwater.

A tractor factory’s a good thing to have, if you care to eat. There was nothing contemptible about making movies about it.”

Ashwin Varma  argues that the usual narrative about WWII industrial production is defective, in that it does not give sufficient credit to the role of government.

The Department of Education embarked on a project to modernize and simplify the process for applying for student aid.    It is not going well.

The Biden administration  is supporting the reopening of a nuclear plant in Michigan.   As Stephen Green says, it’s the right thing to do, but the Democrats doing it reeks of desperation.

gCaptain  is a good source on the Baltimore bridge disaster and on all matters nautical.

In my post Visit to a Noteworthy Robot, I described a trip to a store equipped with Amazon’s no-check-out system.   Now, Amazon has decided to drop this system in most of the stores in which it is being used…problem is that too much human intervention (1000 people in India reviewing images that the AI can’t reliably interpret) to be cost-effective.

An argument that the theft of national sovereignty at the Euro level was orchestrated entirely by legal elites – not political, much less economic, ones.

What kind of people tend to block (what they think are) sources of misinformation?

GE’s energy business has now been spun off as a separate corporation, GE Vernova.   They seem to be pretty well-positioned in nuclear; it will be interesting to see how much emphasis they put on this sector vis-a-vis their gas and wind businesses.

Speaking of nuclear, here’s a chart on the temperature ranges required for various industrial processes versus the temperature ranges available from various types of reactors.

A participant writes about the early days of numerical control machining and also discusses how definition of complex aircraft shapes was done prior to the computing era.   Imagine the labor intensiveness of that process, which descended from traditional shipbuilding techniques but surely required a much higher degree of precision when applied to aircraft production.

A Bendix G-15 computer was used for the NC work described at Northrop, with paper punched tape as the communications medium between the computer and the machine tool.   There is a Bendix G-15 at the American Precision Museum in Vermont, along with many machine tools and other interesting exhibits–see my post here.   Recommended visit for those interested in the history of technology.

What kinds of people are attracted to mass movements?   “(Eric) Hoffer emphasizes that creative people–those who experience creative flow–aren’t usually attracted to mass movements.”   (Twitter)   Makes sense, but is this really true?   Seems to me that there were quite a few creative scientists and artists who were strongly attracted to Communism, and I can think of at least one supposedly-creative philosopher who was strongly attracted to Naziism.

Book and Movie Review: The Valley of Decision

by

This 1942 book by Marcia Davenport could be subtitled An Industrial Romance, as could the 1945 movie starring Greer Garson and Gregory Peck.

Pittsburgh, 1873. The Scott family owns a steel mill, and sixteen-year-old Mary Rafferty has just started work as maid in their home.   There are 5 Scott children, but 17-year-old Paul is the only one who truly values the mill as anything other than a source of dividends.   William Jr, the eldest, is   engaged to a young Boston socialite and wants to to maximize his take from the mill to support their joint social ambitions.   Elizabeth is “plain and angular and earnest, full of purpose and good works.”   The twins Constance and Edgar, 9-year-olds when Mary first meets them, are always into mischief–“known in the backyards and nurseries of Western Avenue as holy terrors and limbs of the devil”…as they grow older, Constance dreams of marrying an English aristocrats, moving to Europe to get away from what she sees as her boring famile, and meeting “all the wicked people,” while Edgar prefers life as a rather raffish gentleman of leisure than doing any kind of serious work.

Paul, though, shares with his father William a strong personal bond with the mill, the work it does, and the people who work there. Will Jr, who as oldest is the presumptive future chief of the mill,   has no desire whatsoever to be a part of scenes such as a Bessemer Converter blow:

And now excitement, familiar but primevally keen, swept everything else aside. The great bulbous brute towering above him began to rumble and belch. From its mouth high overhead a stream of scarlet flame threw itself at the acid winter sky. The blower gave a sign. The blow was ready, and suddenly the usual concert of barbaric noises in the shed was drowned in one fearful ear-crushing roar as the cold blast was shot into the converter’s belly.   Element grappled with element, oxygen in a death-struggle with carbon, a battle more terrible and wonderful than man had ever made before.   The flame, steady and fearfully red, began to change color, a descending scale of blinding flashes echoing from the death-and-birth agony of the elements. Inside the beast steel was being born, and from the vessel’s roaring mouth the solid fire changed from red to blue, to orange, to yellow…

Paul does see things differently from his father in that believes that a more scientific approach to steelmaking will be necessary if they are to compete successfully with giants like Carnegie Steel. When he returns from college he sets up a metallurgical laboratory at the mill, and an open hearth furnace is installed to help in the switch of focus to specialty steels.

There is an immediate strong attraction between Paul and Mary, but the are obstacles–not only the very different class positions of Paul and Mary, but the fact that Mary’s brother..a key skilled worker at the mill…is also a labor leader, attempting to organize a union among Scott employees. And while William Scott Sr does care about his workers, he will resist any attempts to interfere with what he see as his management prerogatives.

Mary quickly comes to share Paul’s emotional bond with the mill, and she also develops a strong sense of connection to and responsibility for the entire family..indeed, more of a sense of connection and responsibility that than felt by some of the family’s own members.

The book begins with Mary starting work for the Scott family, but the history of the mill goes back further, to its founding by Paul’s immigrant grandfather–and the book extends the story through multiple generations, up through the early years of World War II.   The mill played an important role in arming Union forces in the Civil War, and a similar role in later conflicts.   The importance of this exemplar of heavy industry to the national defense is played up strongly, as one might expect in a book published in 1941.

Cable news…past and future

The Golden Age of Substack.   Basically, a revitalization of long-form blogging.

Earth Day as a formal religious holiday?   (It strikes me that this fits right in with energy secretary Granholm’s call for electrification of all military vehicles by 2030.   This is so disconnected from any military or technical rationale that it can only be religiously motivated)

Absence of maternal warmth in childhood has some serious long-term implications.

The Golden age of Aerospace:

Aerospace is one of the deepest branches of humanity’s technological tree. It is a telling fact that more countries have produced a nuclear bomb than mass-produced a jet engine. Recent history illustrates how hard it is to build these capabilities.  

China is recruiting former air force pilots from the West.   And see this post about Jeffrey Katzenberg (Dreamworks), Joe Biden, and China.   More here.

Black Powder.   Still militarily important, though as an initiator for more-powerful explosives rather than as a primary explosive in its own right.   The US was dependent on one.single.factory to manufacture this substance.   It blew up.

Fiction as simulation:

Much like the way a differential equation can summarize the properties of a pendulum, fictional literature abstracts, summarizes, and compresses complex human relations by selecting only the most relevant elements. This abstracted level of comprehension also enables one to see how these principles apply elsewhere and how they may be generalized…Like mathematics, narrative clarifies understandings of certain generalizable principles that underlie an important aspect of human experience, namely intended human action.
