Tell that to the Education big wigs who think algebraic concepts should start in elementary even though it's not until middle school when kids start to grasp "abstract" concepts.

Do those same people who cook, shop, hang a painting and drive use, say, US History? Or Civics?

Dang it! Can't type the division symbol used.

50 / _____ = 25

How is that different from:

50 / x = 25 ?

It's not. That is the algebraic concept

It used to be more along the lines of i

50/2= _

Even when I was in 2nd and 3rd grade we got things along the lines of
Something math operation box = something.
Kids could do it. But replace the box with x and people lost their minds. They couldn't grasp that a letter could represent a number. To me that's where a lot of the "can't do abstract algebra " phobia starts.

"What's the vector, Victor?"

Oh shoot, I started the Jame Bond with too 1.25X too much vodka what do I do? The guy/gal with zero algebra would trash it in frustration and start over. The guy/gal with a glimpse into algebra with simply use 1.25x as a multiplier and make it work. Stipulation I realize a few recipes do not scale up or down as easily.

Science fiction in the 40s, 50s and early 60s was different from what most of it is today. Of course it was mostly written by White Men who were almost certainly racists but they had a different attitude about science and technology than what you will get today.

Check out: A Fall of Moondust by Arthur C Clarke

It is very funny since he writes about infrared and Lagrange points and we now have the James Webb Space Telescope at the Earth-Sun L2 point doing infrared telescopy. Clarke would love it.

SF was invaded by literary intellectuals who didn't know much science writing what they called science fiction. Someone told me that Isaac Asimov couldn't write. So what really matters in SF, the science or the writing?

Compare The Dispossessed by Ursula K Le Guin to Voyage from Yesteryear by James P Hogan. Both are about socio-economic dichotomies but I would bet that Hogan knew more about technology and economics.

Checkout Space Cadet by Heinlein, originally written in 1948. In it he has the Space Patrol headquarter in Colorado just east of Pike's Peak. In one of the very opening scenes he has the newly arriving cadets talking on his portable phone and another mentioning he packed his so his parents couldn't call.

Today the Space Force is currently in Colorado Springs and cell phones are everywhere.
