TV Series Review: “American Genius”

Over at The Lexicans, Bill Brandt posted an item about an 8-part TV series titled ‘American Genius’…it is about a selection of inventors and entrepreneurs who have had a major impact on technology, society, and history.  It sounded worthwhile and I’ve watched about half of the episodes–thanks, Bill!…definitely worth watching, but OTOH I think there are a few things in the series that should have been covered a little differently.

Edison vs Tesla  is about the AC-vs-DC power wars, and correctly reports on the sleazy fearmongering tactics that Edison used in his unavailing attempt to maintain DC’s dominance.  The show referred to George Westinghouse, who was Tesla’s sponsor in this battle, as “sort of a railroad baron,” completely ignoring the fact that Westinghouse was himself a major American inventor.  Most people would think of a ‘railroad baron’ as someone who owns or manages railroads, not someone who invented the air brake.

Farnsworth vs Sarnoff  is about the battle to dominate the emerging television industry.  It was presented as a David-versus-Goliath story–though Goliath was in this case named David (Sarnoff)–individual inventor versus ruthless tycoon.  Sarnoff was indeed ruthless, indeed could be fairly referred to as a prototypical crony capitalist…but it would have been interesting to point out that he wasn’t always a Goliath, wasn’t born to that position, but had in fact come to this country as an impoverished Russian Jewish immigrant and had encountered severe and career-threatening anti-Semitism on his path to Goliath-dom.

Space Race  is focused on two individuals, the German/American Wernher von Braun and the Soviet rocket designer Sergei Korolev.  Korolev was played by an actor who looked a little too young for the role at the subject time period:  more importantly, it should have been mentioned that Korolev had been arrested and sent to the Gulag, where he lost most of his teeth due to the brutal labor-camp conditions.  There were psychological scars as well–Boris Chertok  , who worked closely with Korolev for years, said that there was only one single time that he saw the man really happy.  In a series focused primarily on the leading characters and their conflicts rather than on technical details, these things deserved to be covered.

The program refers to a successful Soviet test in 1957 of a missile with intercontinental range, shortly before the launch of Sputnik.  Actually, the test was a failure because the warhead disintegrated on reentry…and reentry, while a critical factor for ICBMs, is not important at all for one-way satellite launches.  The American belief that Sputnik meant all of our cities were vulnerable to Soviet missiles was a little premature–not much.

I thought Wernher von Braun got off too easily in this program.  The show did mention that the V-2 missile was assembled by slave labor in an underground factory adjacent to a concentration camp: the truly horrific nature of V-2 manufacturing (this was possibly the only weapons system ever made that killed more people in its making than in its employment) could have gotten more emphasis, and the evidence is that von Braun was fully aware of what was going on in this place.

I’m also not convinced that von Braun was as absolutely critical to US missile and space programs as the show implies.  The program to build the Atlas missile, which was developed in roughly the same time period as Korolev’s R-7, was directed by USAF General Bernard Schriever, with technology expertise provided largely by the newly-formed Ramo-Wooldgridge Corporation and by Convair.  I see no reason why this team could not also have conducted a Moon program, had they been so chartered.

The show does point out that von Braun, in addition to his technical and management contributions, played an important role in popularizing the ideas of rocketry and space travel…I had been unaware of his work with Disney to this end.  So, in addition to being a genuine rocket scientist (and, arguably, a war criminal in at least a moral sense), von Braun was also one of the great PR men of the century.

Again, with the omissions and missed opportunities, the series is still very much worth watching.

The Sun

From NASA TV, here’s an image of Mercury transiting the sun today:

That image gives  a good feel for the scale of the planets versus the sun. Earth would appear a little more than twice that size.  Here’s an amazing 4k time lapse video of the sun in various ultraviolet wavelengths. Based on the scale of Mercury in the image above, pick out a small feature in this video and consider the entire Earth would probably fit inside it. Then by comparison, consider the scale and the energies of the loops and streams and mass ejections in this video.

The video is even more amazing just left running in full screen on an HD monitor . It’s completely mesmerizing.

The Mars Chronicles

Little noticed by many, but SpaceX has moved another step towards a Mars landing (from Nasa Spaceflight).

SpaceX has entered  into an agreement with NASA for a Dragon mission to Mars, set to take place as early as 2018. Known as “Red Dragon”, the variant of the Dragon 2 spacecraft will be launched by the Falcon Heavy rocket, ahead of a soft landing on the surface of Mars. The mission is also part of an agreement with NASA to gain further data on Mars landings.

Getting mankind to Mars was the original purpose for the creation of SpaceX. Everything they have done, from building the Falcon rocket to creating the commercial launch service, has been to lay the technological and financial foundation  for putting people on Mars, permanently. The next developmental step is to build and test the Falcon Heavy, a three booster version of the Falcon rocket.

Falcon Heavy

Falcon Heavy will generate over 5 million pounds of thrust from 27 Merlin engines  (9 engines x 3 cores) and have a payload of 119,000 lb to LEO and 30,000 lb to Trans-Mars  Injection orbit (TMI) and 26,000 lb direct to Mars. Launch cost, minus payload, is expected to be around $90 million. According to Elon Musk,  “Falcon Heavy will carry more payload to orbit or escape velocity than any vehicle in history, apart from the Saturn V moon rocket.” Falcon Heavy is expected to debut this year and make its maiden voyage from Vandenberg AFB. According to their agreement with the USAF, certification to carry national security payloads will occur after 3 successful flights and 2 successful consecutive flights.

CRS-8 Dragon: Hosted Webcast

It’s steps like this that move the space program forward. Notice this wasn’t done by NASA or ULA or the ESA. It was done by a private company that didn’t exist 15 years ago. 37 minutes, including the launch, recovery of the 1st stage, and deployment of the Dragon capsule.

BTW, very cool to me that Spacex did not require the help of a traditional media company for any of this. And it’s actually much better than anything they typically produce. In addition, the people in this video are in the Hawthorne, California, SpaceX facility where these rockets are designed and produced. They designed and built this rocket. And they’re watching it perform almost real time. How amazing is that?

The Fermi Paradox and SETI

The Atacama Compact Array
The Atacama Compact Array

In 1950, amidst the UFO hoopla that was sweeping the world, Italian physicist Enrico Fermi posed a simple question, Where are they? By that he meant with lots of people making the argument that in a universe full of stars presumably with planets there should be lots of intelligent life out there. That seems plausible. So, he wondered, how come there isn’t a shred of evidence for it? After all, if we lived in a city full of people, wouldn’t we see them or at least see evidence of them being there? So why don’t we?

Kepler

In 1961 astronomer Frank Drake, interested in that very question, made an estimate of how many intelligent civilizations should exist inside our galaxy. The Drake Equation has seven terms, each a guess, from how many stars are born per year and how many of those have habitable planets through how many of those planets have developed technologies (like radio) that allow them to be detected. In 1961 there was not enough data to give reliable estimates to any of the terms. In the intervening 50 years we’ve accomplished enough basic research to apply actual values to the first few terms.

The Milky Way produces about seven new stars per year. Virtually every star forms within a disc of gas and rock/metal dust called a protoplanetary disc that eventually condenses into planets. According to research derived from data collected by the Kepler spacecraft, at least 22% of Sun-like G type stars have an Earth-like planet in the habitable zone, the habitable zone being defined as the distance at which water neither boils off or is continuously frozen. Result: the number of habitable Earth-like planets in the Milky Way is at least 50 billion.
