In my poverty I learned how to keep cars running.

Once upon a time I replaced the head gasket of my Toyota station wagon in a K-mart parking lot.

Late 'seventies early 'eighties I drove all over the western U.S.A. and Baja Mexico in that car.

At times I lived in that car as well. With all my tools.

I took my first driver's test in an Volkswagen van. My parents are artists. Of course they drove a Volkswagen van.

The DMV examiner looked at me like I was a freak. I don't remember for certain, but I may have been wearing violet pants. Certainly my hair was long and confusing to people who needed to know if I was a boy or a girl.

My first serious girlfriend was an engineer attracted to the heroin waif look which I naturally achieved without the heroin. She could show me off to her parents as the guy she was going to marry.

I never showed her off to my parents because I was pretty sure they would have told me I was going wrong.

Praise be to God that marriage did not happen, a match made in hell, the David Lynch version of My Big Fat Greek Wedding without the Greek.

She married someone else, a woman who had tried to kill herself in my bathtub. If I ever get some kind of gold star fast pass at the Pearly Gates it's for making that match.

My wife and I met teaching science in the big city.

Back to cars...

When I was driving all over the place gasoline was essentially free. I'd get jobs paying eight to ten dollars an hour. I could fill the tank of my car working an hour. I could get a warped engine head milled flat with a day's work.

That car culture was awesome.

As a rabid environmentalist my secret vice is Jay Leno's Garage...



He talks about Ralph Nader in this video.

Ralph Nader is an asshole.

In my utopia I get up before dawn so I'm running as the sun rises. When I return from running I shower and work six hours or so, no automobile commuting involved.

I've managed to live like that for some of my life. Alas, severe arthritis now interferes with my running, but I still like to watch the sun rise.

The most hellish jobs I had involved long automobile commutes in stop-and-go traffic, leaving for work in the dark and arriving home in the dark.

There's no good reason for anyone in modern technological society to work as wage slaves except that a few powerful people profit immensely from it.

Most of us suffer work that is not making the world a happier place.

This thing we call economic productivity isn't productivity at all. It is in fact a measure of the damage we are doing to our earth's natural environment and our own human spirit.

The high technology world economy now runs on a single universal time. The local time is calculated from that.

Time zones were originally invented by the railroads. Railroads had to run by a single clock, for safety and scheduling reasons. Railroad time was set by telegraph and chronographs.

Before railroad time local communities had their own local time loosely synchronized to "high noon."

Later radio and television broadcasting followed railroad time.

If we wanted to we could go back to local time and use a single universal time only for those activities that require it.

We could even build clocks with variable hours so the day in a community would always began at dawn. That's the environment humans evolved in; that's the rhythm the internal clocks of our bodies follow.

... yet some speculate we humans might be somehow unique and alone in this universe because we haven't yet met any space aliens like us.

If we can't see that spark of sentience and intelligence in our own immediate neighbors, how the hell would we recognize it in space aliens?

Maybe that's why space aliens avoid this place.

I've known many amazingly bright dogs and birds, even a few cats, and I love to watch videos of elephants, horses, and cetaceans who are clearly thoughtful and playful creatures who celebrate life.

It makes me sad there are humans who won't even respect the individuality of fellow humans beyond their own small tribes, and in the worst cases of sociopathy and narcissism, beyond their own selves.

The sole purpose of school sports should be to promote the physical well being and positive social interactions of students.

Maybe these sports once had some evolutionary value in human societies, back when raw physical prowess and testosterone poisoned comradery won wars, but none of that makes sense now, not since humans gained the ability to destroy their enemies by electronic propaganda and economic warfare, or in MAD scenarios, by throwing around nuclear weapons on missiles.

I'm thinking of my grandfather here. He was an Army Air Corp officer in World War II. He joined the Army Air Corp to escape rural Wyoming, see the world, fly planes, and woo the ladies wherever he landed. Unfortunately he was also a klutz. Watching him ride a bicycle, or swim in anything but a small surf, were some of the most terrifying things I witnessed as a kid. Grandpa is going to die! The Army, in its wisdom, did not let him fly airplanes or play with guns. I've heard he flew an airplane once. Just once. And none of his relatives would invite him hunting.

I can still hunt, I like to believe, but haven't in the 21st century. I flew an airplane once. Didn't take off or land. Didn't break anything.

My grandfather was some kind of wizard with exotic metals, and a competent intermediary between ordinary military society and brilliant people far weirder than he was. He never talked about his military service. He did a dirty job that had to be done and I suspect a lot of it was messy and secret. His knack for making impossible parts out of exotic metals is unexplained.

He would talk about bits of metal he made for the Apollo Project. He was fiercely proud of that.

I'm a klutz. School sports culture was hell on me. In sixth grade they used to leave me far out in left field picking through the grass, biologist that I am, even as the innings changed. I was always last pick, after the kid with the tremor and coke bottle bottom glasses because he was always nice. I was not always nice. I could break noses with my elbow.

I quit high school. Never attended a football game or dance. Didn't care.

In college I got to know a lot of people in co-ed recreational running and softball, and that's when I finally understood the value of sports.

I've no concerns that Biden and Harris won't appoint extraordinarily competent people, even people who are not currently political celebrities.

Personally I'd like to see more government positions filled by utterly boring technocrats.

My political utopia looks a lot like Star Trek TNG.

Make it so. Make it so. Make it so.

... others have mistaken arguments put forth by people who are serious (but blatantly wrong) for sarcasm.

This creates a bitter storm of internet controversy.

The people who can't laugh on either side (right or wrong) are the most offended.

BTW, my own response to that thread was sarcastic.

Or maybe not. Is it possible to count the electrons in empty space?

https://en.wikipedia.org/wiki/Quantum_fluctuation

Is it even possible to count electrons?

John Wheeler proposed all electrons and positrons are actually manifestations of a single entity moving backwards and forwards in time.

It complicates things immensely if all the electrons we count are just the faces of a single electron that's very, very busy.

Engineering electronics today, especially on the scale of modern microprocessors and computer memories, requires a fairly sophisticated understanding of quantum mechanics. Naive interpretations of electronics, most especially the "water in a pipe" analogy where voltage is analogous to water pressure, and amps are analogous to the volume of water, turn out to be fairly useless. "Counting" electrons "flowing" through a conductor gets weird.

I've seen know-it-all techs heatedly arguing uselessly with physicists, no information being transferred in either direction, because their understanding of a problem isn't even on the same plane.

When a mathematician argues 2+2=4 they have very precise understandings of objects, integers, and operations. Other interpretations, especially those based in non-rigorous languages, can be dismissed.

The scary thing about human languages such as English -- and the most wonderful thing as well -- is that we can say things that are untrue, things that might be true, and things that are close enough to the truth for everyday use.

But science requires something more precise than "everyday use" and develops its own languages, especially the languages of mathematics.

If we don't know these languages of science we can't make scientific arguments, and it's silly to argue that 2 + 2 = 5 in some alternative context. If there really is some alternative context (not likely...) then it's up to the developer or observer of that context to create the rigorous language that explains it.

Otherwise they are simply stomping on the highly developed and precise languages of others, which may be the very crime they are accusing others of doing, the equivalent of some MAGA hat wearing fool in WalMart yelling "This is America, speak English!" to shoppers speaking Spanish in the checkout line.

This is an amazing book. Check it out.

I hope it's not prescient of our actual future.

People learn their culture's version of a healthy diet as children, which is why learning other sorts of diets as adults seems difficult.

Some cultures have healthier diets than others, but no culture has a traditional diet that is so unhealthy it can't sustain the population.

Human diets evolve. In human history people have created healthy diets by trial and error. They may not have had specific scientific knowledge of nutrition, they just knew which combinations of foods they needed to eat to stay healthy.

In some animals this dietary knowledge is largely instinct, in other animals such as humans, bears, sea otters, etc., specific diets are learned behaviors.

There are seven and a half billion people on this planet now. We can't all eat large quantities of meat every day without doing very significant damage to whatever is left of the earth's natural environment.

About half the people in my extended family are vegetarian, many of them nearly vegan. The reason they have chosen these diets are varied. I've seen children thrive on such a diet and grow up to be very healthy adults.

Times change. Three of my grandparents were the children of ranchers and dairy farmers. All of my great grandparents were Wild West, the meat they ate they killed themselves. As a little kid I used to watch my great grandmas cut up fish, chickens, and small mammals for dinner with awe. Their hands moved faster than I could follow.

My dad doesn't like hunting much, but he's an avid fisherman. When my siblings and I were children most of the animal protein we ate was fish he caught, followed by cheap powdered milk, bulk cheese, and ground up dairy cows.

An even greater number don't let anyone they'd care to shoot live in their heads.

This has severely limited the market for new guns.

It wasn't the worst job I ever had, but it was bad.

He had a property he only rented to women, on the theory that young women were less likely to do serious damage to this property.

Which was probably true. He'd bought it from a woman who told him so.

One Friday morning the water heater failed.

I could have replaced it myself, at some late Friday afternoon cost, but Mr. Slumlord decided it would be less trouble and less expense if he waited until Monday, and told me to go around and apologize.

I should have killed him then, dissolved his body in a vat full of lye, and flushed it down the toilet, but I was just over a bit of psychotic living in my car homelessness and didn't want lose the job.

Really, what's suffering cold showers for the weekend?
