Review: Thunderstruck by Erik Larson

In The Devil in the White City, author Erik Larson interleaved the story of Chicago's Columbian Exposition with that of a particularly depraved serial killer operating nearby at the same time.  Similarly, his also nonfiction Thunderstruck tells the story of Marconi's development of radio and another sensational crime.  I bought the book because I was interested in the early development of radio.

While the crime at the center of the book has many peculiar and suspenseful aspects, I was quite disappointed in the history of Marconi.  Larson has unearthed many stories of his fanatical dedication, and his struggles with rivals and competitors, the book, and I expect the author, is almost entirely innocent of any discussion of the actual technical difficulties encountered and overcome.

There is much about giant towers and antennas, their destruction by weather, giant sparks illuminating the darkness and shattering the silence with their thunderous booms, their is almost nothing about what is really going on in the electromagnetic spectrum.  Marconi was not a physicist.  Like Edison, he operated by cut and try.  Even though his efforts won him the Nobel Prize in Physics,  he confessed his lack of technical comprehension his acceptance speech.

Crucial details about the waves generated, and how they were tuned, are completely absent.  We are told  about the crucial role of tuning, but not told anything about how Marconi did it.  We are told that the invention of the thermionic valve (a vacuum tube diode) was important, but not told anything about its role (or even that it is a vacuum tube diode)).

I give this a B-, because the story is interesting and otherwise carefully told.

Anti-Libertarian: re-post

The most pointed critique of social security and liberalism in general is the libertarian critique. The problem with libertarians, for a liberal, is that we have too much in common. We both believe in individual rights, tolerance of individual differences, and dislike government prescription of religion. The basic difference, it seems to me, is the different answers we give to Cain's (with thanks to the Captain - my original version had the corpse asking the question!) famous question: "Am I my brother's keeper?" That's not really my basic bitch against the libertarians though. My real complaint is the same as my complaint against most religion - its premise is a fraud. For those who can't stand to wait for the punchline, I believe that trying to implement libertarian principles leads to tyranny or social disintegration. Demonstrating that takes some historical (and pre-historical) context. For all but the last 15,000 or so of the 100,000 years the human spec

Uneasy Lies The Head

Uneasy lies the head that wears a crown ........... Shakespeare Henry IV, Part II. So it is with us and our slightly distant primate cousins , so it seems. A 9-year study of wild baboons in Kenya by Princeton University and the Institute of Primate Research may turn conventional assumptions of alphas males upside down. The study found that alpha males have high testosterone levels, which allows them to dominate other baboons, get access to more food, and attract better mates. This is expected. Surprisingly, though, the alpha males also have high levels of stress hormone glucocorticoid, which scientists measured from their feces samples. In fact, the stress of alpha baboons was on par with low-ranking baboons. The convention wisdom is that access to food and females provides life security and thus less stress for dominant males. Conversely, weak males who are constantly threatened by starvation and physical violence from stronger males are thought to be more stressed. The st

We Call it Soccer

The US played its best, and maybe only good game of World Cup, but lost thanks to brilliant goalkeeping by the Swedish keeper and the bizarre method soccer uses to settle ties when three US stars could not put the ball on frame from the 12 yard spot.  At the end it came down to a blocked shot that spun in by maybe a couple of centimeters. Well, that's football - too much like life.   Which brings me to a modest proposal.  Replace the thirty minute overtimes with as many 7-player 15 minute periods as needed to settle it.  Scoring should be much easier with fewer players.
