Why would anyone name a car company after a guy famous for delusional overpromising?

One doesn’t learn much history in Electrical Engineering skool. I had a dim perception of Nikola Tesla as someone who turn Katherine Clerk Maxwell‘s equations into practical AC generators and AC motors. So it seemed to make sense that an electric car company would be named after Mr. Tesla.

During my recent trip to China, I decided to read up on the pioneers of the technology that has made China the modern industrial powerhouse (so to speak) that it is.

I started with My Inventions, The Autobiography of Nikola Tesla. Tesla wrote the book in 1919 at the age of 63 (he would die in 1943, in poverty and debt, in the New Yorker Hotel at age 86). He is enthusiastic about invention:

The progressive development of man is vitally dependent on invention. It is the most important product of his creative brain. Its ultimate purpose is the complete mastery of mind over the material world, the harnessing of the forces of nature to human needs.

Tesla implied that his personality was inherited:

My mother was an inventor of the first order and would, I believe, have achieved great things had she not been so remote from modern life and its multi fold opportunities. She invented and constructed all kinds of tools and devices and wove the finest designs from thread which was spun by her. She even planted seeds, raised the plants and separated the fibbers herself. She worked indefatigably, from break of day till late at night, and most of the wearing apparel and furnishings of the home were the product of her hands. When

Very quickly the delusions begin

My sight and hearing were always extraordinary. I could clearly discern objects in the distance when others saw no trace of them. Several times in my boyhood I saved the houses of our neighbors from fire by hearing the faint crackling sounds which did not disturb their sleep, and calling for help. In 1899, when I was past forty and carrying on my experiments in Colorado, I could hear very distinctly thunderclaps at a distance of 550 miles.

In Budapest I could hear the ticking of a watch with three rooms between me and the timepiece. A fly alighting on a table in the room would cause a dull thud in my ear. A carriage passing at a distance of a few miles fairly shook my whole body.

Isn’t it a good working definition of “delusional” to hear things that nobody else hears?

Bad news for Tesla shareholders:

If my memory serves me right, it was in November, 1890, that I performed a laboratory experiment which was one of the most extraordinary and spectacular ever recorded in the annals of Science. In investigating the behavior of high frequency currents, I had satisfied myself that an electric field of sufficient intensity could be produced in a room to light up electrode less vacuum tubes. Accordingly, a transformer was built to test the theory and the first trial proved a marvelous success. It is difficult to appreciate what those strange phenomena meant at the time. We crave for new sensations, but soon be come indifferent to them. The wonders of yesterday are today common occurrences.

(I still like Dog Mode, though, having asked for it back in 2003!)

Speaking of Dog, Tesla wanted to compete with God:

One day, as I was roaming the mountains, I sought shelter from an approaching storm. The sky became overhung with heavy clouds, but somehow the rain was delayed until, all of a sudden, there was a lightening flash and a few moments after, a deluge. This observation set me thinking. It was manifest that the two phenomena were closely related, as cause and effect, and a little reflection led me to the conclusion that the electrical energy involved in the precipitation of the water was inconsiderable, the function of the lightening being much like that of a sensitive trigger. Here was a stupendous possibility of achievement. If we could produce electric effects of the required quality, this whole planet and the conditions of existence on it could be transformed. The sun raises the water of the oceans and winds drive it to distant regions where it remains in a state of most delicate balance. If it were in our power to upset it when and wherever desired, this might life sustaining stream could be at will controlled. We could irrigate arid deserts, create lakes and rivers, and provide motive power in unlimited amounts. This would be the most efficient way of harnessing the sun to the uses of man. The consummation depended on our ability to develop electric forces of the order of those in nature.

Though he also believed in God:

[World] Peace can only come as a natural consequence of universal enlightenment and merging of races, and we are still far from this blissful realization, because few indeed, will admit the reality that God made man in His image in which case all earth men are alike. There is in fact but one race, of many colors. Christ is but one person, yet he is of all people, so why do some people think themselves better than some other people?

Tesla was not daunted by failure:

I have refrained from publicly expressing myself on this subject before, as it seemed improper to dwell on personal matters while all the world was in dire trouble. I would add further, in view of various rumors which have reached me, that Mr. J. Pierpont Morgan did not interest himself with me in a business way, but in the same large spirit in which he has assisted many other pioneers. He carried out his generous promise to the letter and it would have been most unreasonable to expect from him anything more. He had the highest regard for my attainments and gave me every evidence of his complete faith in my ability to ultimately achieve what I had set out to do. I am unwilling to accord to some small-minded and jealous individuals the satisfaction of having thwarted my efforts. These men are to me nothing more than microbes of a nasty disease. My project was retarded by laws of nature. The world was not prepared for it. It was too far ahead of time, but the same laws will prevail in the end and make it a triumphal success.

Tesla was an isolationist and would have to agree to disagree with Greta Thunberg:

As I view the world of today, in the light of the gigantic struggle we have witnessed, I am filled with conviction that the interests of humanity would be best served if the United States remained true to its traditions, true to God whom it pretends to believe, and kept out of “entangling alliances.” Situated as it is, geographically remote from the theaters of impending conflicts, without incentive to territorial aggrandizement, with inexhaustible resources and immense population thoroughly imbued with the spirit of liberty and right, this country is placed in a unique and privileged position. It is thus able to exert, independently, its colossal strength and moral force to the benefit of all, more judiciously and effectively, than as a member of a league.

He was interested in aviation:

As stated on a previous occasion, when I was a student at college I conceived a flying machine quite unlike the present ones. The underlying principle was sound, but could not be carried into practice for want of a prime-mover of sufficiently great activity. In recent years, I have successfully solved this problem and am now planning aerial machines devoid of sustaining planes, ailerons, propellers, and other external attachments, which will be capable of immense speeds and are very likely to furnish powerful arguments for peace in the near future. Such a machine, sustained and propelled “entirely by reaction,” is shown on one of the pages of my lectures, and is supposed to be controlled either mechanically, or by wireless energy. By installing proper plants, it will be practicable to “project a missile of this kind into the air and drop it” almost on the very spot designated, which may be thousands of miles away.

He also wanted to do AI and self-driving cars!

But we are not going to stop at this. Telautomats will be ultimately produced, capable of acting as if possessed of their own intelligence, and their advent will create a revolution. As early as 1898, I proposed to representatives of a large manufacturing concern the construction and public exhibition of an automobile carriage which, left to itself, would perform a great variety of operations involving something akin to judgment. But my proposal was deemed chimerical at the time and nothing came of it.

That’s Tesla in his own words. The next post will have some links from a biography.

Colds will become less prevalent due to cashless economy?

From a Mexican’s point of view, American counter-service restaurants and ice cream stands do something completely unsanitary: the person handling the cash is also the person handling food.

At least in the Shanghai region, I noticed that the Chinese usually separate food-handling from customer-handling (not really “cash handling” since WeChat is the typical method of payment.)

I’m wondering if Americans will get fewer colds as we transition to a cashless economy. If everyone who goes to a counter pays by inserting a credit card into a machine or waving a phone, shouldn’t there be less chance of an infection being passed from customer-to-clerk-to-customer?

I couldn’t find good research on this subject. China would be an interesting case study since they have gone mostly cashless in a short period of time. Anecdotally, it was rare to see someone (Shanghai in November) suffering from a cold and I never got any hint of food poisoning.

But maybe this isn’t interesting because the effect will be small and swamped by increased transmission of disease due to increasing population density (from (a) population growth, (b) migration and urbanization).

What’s happening on the Turkey/Syria border?

Just a few months ago, Americans couldn’t live without news about Turkey, Syria, and the Kurds, e.g., “Kurds say Turkey is violating hours-old ‘ceasefire’ in northern Syria” (CNN, October 18, 2019)

Our media is now silent on this topic. Did whatever the problem was resolve itself? Or Americans stopped caring? Or what?

Aviation weather reports at the time of Kobe Bryant crash

Friends have been asking me about the Sikorsky S-76 helicopter crash that killed Kobe Bryant today. weather.com says that the crash occurred on January 26 close to 10:00 am and that conditions were cloudy/foggy.

Calabasas, California is between the Burbank and Camarillo airports. Here are their respective weather reports from around that time (10:00 am California time is 18Z). Burbank was right on the edge between visual and instrument flying conditions:

KBUR 261753Z 00000KT 2 1/2SM HZ OVC011 12/09 A3016

Translation: Burbank airport, 26th of the month, 17:53 UTC (9:53 am Pacific Standard Time), wind calm, 2.5 miles of visibility (“statute miles”), haze, temperature 12C, dewpoint 9C, altimeter 30.06. The nearly adjacent Van Nuys, airport, …

KVNY 261751Z 00000KT 2 1/2SM HZ OVC013 12/09 A3016

(almost identical)

Camarillo, closer to the coast, was slightly better:

KCMA 261755Z 03003KT 4SM HZ OVC017 15/11 A3019

26th at 1755Z (9:55 am), wind from 030 (NE) at 3 knots, 4 miles of visibility, haze, overcast clouds at 1,700′.

Over the hill at the Santa Monica airport that Californians are always getting into fights about?

KSMO 261751Z 12003KT 5SM HZ OVC018 14/09 A3018

(Translation: Santa Monica airport, Jan 26 at 17:51Z (9:51 am local time), wind from the southeast (120) at 3 knots, 5 miles of visibility in haze, clouds 1,800′ above the airport, temperature 14C, dewpoint 9C, altimeter setting 30.18.)

Assuming that it was bad weather that led to this accident, the engineering question is “Why couldn’t the $10 million helicopter fly itself away from obstacles, the way that a $400 DJI drone can?”

A Sikorsky is equipped with multiple computer-readable attitude sources so that the onboard processors know whether the machine is pitched or banked. It has multiple GPS position sensors so it knows where it is. It has at least one terrain database so it knows where the obstacles are. It has autopilot servos capable of maneuvering the aircraft. Why doesn’t it have the intelligence to say “You’re about to hit something, would you like me to take over and fly away from these obstacles and park on the ramp at the Van Nuys Airtel so that we can all relax?”

From flightaware.com:

The track log shows a rapid climb during the last minute of the flight, perhaps an attempt to climb away from terrain (ignore the “PM” after the time; FlightAware translated to Eastern time):

Skyvector chart for the area in question:

Note the red circle indicating a temporary flight restriction around the crash area. Also note the “5.2” above the red circle, indicating that one has to be 5,200′ above sea level in order to clear all of the obstacles in this part of the chart. (Google Earth shows that the highest terrain near the media-reported crash site of the 4200 block of Las Virgenes Rd. in Calabasas is around 1,100′)

An alternative presentation of transponder (ADS-B) data from flightradar24:

A YouTube video puts together the flight’s track with Air Traffic Control communications (presumably from liveatc.net). The pilot reported being at 1,400′ or 1,500′ above sea level. The Burbank and Van Nuys airports are 800′ above sea level. So this was 600-700′ above the ground (low for an airplane, but within the realm of normal for a helicopter) and thus, if the cloud layer had a flat bottom and the weather reports over 1,100’+ ceilings were accurate, the helicopter should not have been in a cloud.

The pilot had held an instrument rating since 2007, though it can be difficult to maintain instrument proficiency in helicopters, which are seldom flown IFR:

He also held a flight instructor certificate, which has to be renewed every two years. He was qualified to act as an instructor for instrument flying in helicopters:

Every American welfare program eventually turns into welfare for rich white people?

“A Surprising Finding on Paid Leave: ‘This Is Not the Way We Teach This’” (nytimes):

One of the biggest arguments for paid leave for new parents has been an economic one: Research has repeatedly shown that women with paid time off after childbirth are more likely to keep working.

But a new study, the largest to be done in the United States, found the opposite. In California, which in 2004 became the first state to offer paid family leave, new mothers who took it that year ended up working less and earning less a decade later. They averaged $24,000 in cumulative lost wages, it found.

For first-time mothers, there was a clear negative effect. After 10 years, the new mothers who took paid leave right after they gave birth were 5 percent to 7 percent less likely to be employed, and those who were employed earned 5 percent to 8 percent less. The researchers said the earnings decreases could be because they worked fewer hours, moved to jobs with lower wages and more flexibility, or became self-employed.

These patterns held no matter the age or prior earnings of the mother, and were true for both unmarried and married mothers, though the decreases in employment were slightly larger for unmarried women

Not too surprising. Pay people to refrain from work and they discover how enjoyable it is to hang out at home!

Usually it takes a while for a welfare program to be co-opted by rich white Americans, but this one was immediately latched onto:

Despite the large sample, the effects were limited to women who took leave immediately after it became available. Only about a fifth of women who gave birth then did so, and that group might have been more inclined to step back from work in the first place.

A variety of research has found that this group was more likely to be older, high-earning, white and college educated than those who took leave after the program had been in effect for a while. Even later, awareness of the program was low, particularly among low earners — exactly the group that research has shown gets the most economic benefits from paid leave.

Brookline Public Schools approve a book about aviation

Good news and bad news for a friend’s 12-year-old…

Bad: he was sentenced to read a book by his teachers in the Brookline (Massachusetts) Public Schools.

Good: One of the choices was on an aviation theme. Maybe this won’t be a painful distraction from video games and learning about technology. Perhaps it will be Fate is the Hunter?

Reality: the assigned book, Fly Girl, turns out to be more about skin color than aviation.

From the Amazon page:

All Ida Mae Jones wants to do is fly. Her daddy was a pilot, and years after his death she feels closest to him when she’s in the air. But as a young black woman in 1940s Louisiana, she knows the sky is off limits to her, until America enters World War II, and the Army forms the WASP-Women Airforce Service Pilots. Ida has a chance to fulfill her dream if she’s willing to use her light skin to pass as a white girl. She wants to fly more than anything, but Ida soon learns that denying one’s self and family is a heavy burden, and ultimately it’s not what you do but who you are that’s most important.

European + Eskimo/Inuit culture = female-led society

My Facebook feed recently lit up with righteous Americans celebrating the a new female-led government in Finland. “Change in Finland: A government led by five women and the world’s youngest prime minister” (Washington Post) was a typical article. More substantive, “Finland’s New Government Is Young And Led By Women—Here’s What The Country Does To Promote Diversity” (Forbes):

The new female prime minister’s coalition government was formed with all five party leaders being women – the majority being under 40-years of age, … Feminists across countries applauded and congratulated the new prime minister inspired what might promise more change and innovative solutions to come. … Research from the past 30 years suggests that quota provisions and the type of electoral system are good predictors for women’s representation in parliament across countries.

The Eskimo/Inuit world, however, reached this milestone decades ago. During our Northwest Passage cruise, I commented to an anthropology professor on board that all of the people we’d met in Nunavut with steady government paychecks were women: the mayor of every town, the teachers and other school employees, etc. She said that it was like that everywhere in the Inuit region of Canada: “Women are the ones to go to college and they run all of these towns, from the mayor on down.”

Here’s the mayor of Cambridge Bay:

In addition to some locally useful content, the library features Women Who Write Are Dangerous:

Traditional Eskimo society, which includes people from the Bering Sea through to Greenland, involved a strong gender-based division of labor (and there were only two gender IDs available). Men were responsible for hunting and making tools. Women were responsible for having babies, taking care of children, technical sewing, and cooking. This was a sustainable way of life for at least 2,000 years.

Europeans barged in with cheap industrial food and factory-made tools, thus devaluing the traditional role of men. Except for the sewing activity, the Europeans made the traditional female role more valuable. Where children had previously been a burden and a woman would have to find a man to help her feed the extra mouths, the government now frees women from all of the costs of child-rearing. As in the U.S., the Inuit woman who gives birth is entitled to government-supplied housing, government-supplied food, and government-supplied health care. What if she has 10 kids? “Every time a child turns 5,” replied a single mom, “the government has to give me a bigger house. It is illegal for children over 5 to share a room.”

The private houses that we saw advertised for sale were absurdly expensive compared to potential incomes for any non-government job. Public housing is $50-100/month; a comparable quality house across the street might be $300,000 to purchase.

(Inuit have among the highest population growth rates in Canada now:

source: https://www.itk.ca/wp-content/uploads/2018/08/Inuit-Statistical-Profile.pdf )

What’s left for the men to do? Some seem to have construction jobs, but there is a lot of alcohol (in industrial quantities, another gift from the European invaders) and Xbox. A teenager told us that his father had 9 children total and had not, as far as he had observed, done anything by way of gainful employment. Suicide statistics are frightening and nearly every Inuit person we met seemed to have a story about a brother or father who’d killed himself.

(https://www.nybooks.com/articles/2019/10/10/inuit-highest-suicide-rate/ : “If Nunavut, the semi-autonomous Canadian territory that is home to roughly 28,000 indigenous Inuit people, were an independent country, it would have the highest suicide rate in the world. The suicide rate in Greenland, whose population is mostly Inuit, is 85 per 100,000; next highest is Lithuania, at 32 per 100,000. Nunavut’s rate is 100 per 100,000, ten times higher than the rest of Canada and seven times higher than the US. When I visited Nunavut’s capital, Iqaluit, in July, virtually every Inuit I met had lost at least one relative to suicide, and some recounted as many as five or six family suicides, plus those of friends, coworkers, and other acquaintances.”)

Why are politicians working overtime on impeachment?

My first exposure to the impeachment show is this evening in a hotel lobby here in Charleston, South Carolina:

Note the time: 10:48 pm. Why are they working beyond normal business hours? Trial courts usually work only 9:30-4 or similar.

If Trump is obviously guilty, why can’t he be convicted on a 9-5 schedule? (Did the House go into these late sessions back in December?)
