Wind turbines used to absorb a power surplus?

Civud-19 is caused by an RNA virus. You can send the genome of a virus over a mobile phone link, but building an actual virus that can infect you requires rather more bulky apparatus.

Not that anybody has seen one. The fertile imaginations of the anti-vaxxers has rather outstripped any facts that might support tem.

The first part is right. The second part misses the point that the replacement lens is a a preformed precision optical lens, which is slid in through a slit, which has to be sewn up. There are needles involved it that but the new lens isn't injected through a needle.

john Larkin may have been through the procedure, but he doesn't seem to have been able to see what was going on.

Not gunna happen. There were enough engineers to fix the

At least we understand that critters that don't breed go extinct.

So the question is whether engineering talent is heritable. Of course it is.

And even people who can't spell.

So about 10 times too big to go in the vaccine hypodermic needle.

There's no single engineering talent, but a whole mix of abilities.

Kids get half their genome from each parent. There's no guarantee that the skills that made the father a good engineer are the same as the skills that made the mother good at engineering, and the kid could miss out on both.

I knew one dyslexic engineer. He was brilliant, but we couldn't persuade him to let us check out what he wrote - he though that if what he wrote sounded right when he sub-vocalised it, it was perfectly okay.

Yes, those. Synchronous generators.

Wind can use both that method or variable speed with inverter and MPPT (following a power vs speed curve) to take advantage of changing wind speeds. It used to be, 20-ish years ago that the MPPT method was patented (by GE ?)... I don't know what large wind companies do these days but I only see small wind using MPPT for wind to charge batteries for off grid.

I think from recent events you will find no-one fixed anything in the banking system. In 2008 it was exposure to some Micky Mouse financial products that started the runs and 2023 it's likely to be exposure to the collapsing Micky Mouse cyrpto market.

Those pet chips were designed decades ago when mobile phones were the size and weight of a couple of house bricks and were limited in functionality. Electronics and nano technology has moved on considerably since then :)

Assuming there are genetic components in engineering talent (and I'm not saying there isn't), it's possible that epigenetic factors determine whether those genes will be expressed.

Nothing "goes" extinct, critters that don't breed "become" extinct.

Sadly, the laws of physics haven't changed. A passive identity chip has pick up enough electric power to activate the electronics, and re-radiate some of it as a detectable signal. You can't scale that down.

It is less genetics than familiarity. I came across a study done in Apartheid S Africa where they evaluated competence in basic industrial practice. Overwhelming the people who did best irrespective of race were those whose parents understood and could handle machines. It is terrifying how STEM inept I have seen intelligent bright children become whose parents were ArtStudents. They expect to fail.

That's just part of how DNA works. The epis are mostly heritable too.

If learned skills are epigentically inherited, which they likely are, engineering talent will really run in families, like math and music and athletics.

That always was the case. RPI had sort of a remedial English class for some of the freshmen and it wasn't geared toward foreign students.

My brother, who was the actual rocket scientist in the family, couldn't spell for sour owl shit. You didn't want him to be the guy painting slogans on the missiles.

Yeah, like my family. Like many working class families the first kid to go to college was going to be an engineer.

If your parents had enough spatial insight to do well with machinery, you might have a better chance of inheriting the same talent, if it happened to be a heritable talent.

What do you mean by "become"? If the parents had a talent in one of the arts which doesn't require spatial insight - some of them do - their kids might not have had the chance to inherit the particular talents which help STEM.

Science Technology, Engineering and Mathematics is a pretty broad field. Mathematics is actually an art, rather than a science, and scientists and engineers tend exploit the artistry of mathematicians rather than contributing original mathematical insights.

The common wisdom when I was in school was if you wound up with an Indian lab partner let them handle the paperwork. They were extremely good with theory and a danger with a screwdriver. At least at that time upper middle class Indian kids didn't spend their childhood working on the family jalopy like most American kids who wound up in an engineering school.

I assume that has changed since the '60s as India developed diverse industries. The talent is there but wasn't encouraged by the British colonialists. India is building better Royal Enfields that the Brits ever did :)
