What was a fact taught to you in school that has been proven false during your lifetime?
-
Unless you are by far the oldest person on Earth, these were disproven far before you were born
Fair, but this is/was still commonly taught in schools. That's what the original question was.

We don't know what the appendix does, the whole pluto thing, I think the Oxford comma is going out of style, and cursive in general.
But I love cursive, mine was "very nice" according to my teachers.
Eh, Pluto isn't really something proven false, just that we found more objects like Pluto that made more sense in their own category. It's classification, like there weren't always separate categories for feature films and short films, there wasn't a separate category for dwarf planets when it was just Pluto.
Oxford comma is useful. I think what's getting popular is just complete disregard for spelling and grammar.

They exist. There's one in my town.

Philippines was a US territory
that hasn’t been true since 1946.
I mean... It was a US territory. Well, at least it was under control of the US in some way. I think one of/the first cruel and unusual constitutional challenges was over something that originated in the Philippines.
I suppose phrasing wins there. I meant u was educated in the 90s that it currently was a territory.

6 x 6 mothefuckers. Y'all tell me that didn't immediately form "36" in your brain.
Nope, went through "(6 × 5) + 6". Slightly slower, but much more flexible since you can do that with any (base 10 representation of a) number that has a reasonable number of digits.

That wasn’t so much a “fact” told in school as it was a prediction, and it was true for them. Some people carried pocket calculators, but most people didn’t. Some supermarkets has calculators built into their carts, but most didn’t.
Failing to predict society’s norms in 20 years isn’t the same as teaching a false fact.
The same was told to me even as everybody already had mobile phones with calculators in them or even iPhones

Did they finally find that out? Last time I checked even PhDs in aerospace engineering still added "we think" at the end of their explanations.
It is known yeah. Another user commented it. If you take a wing and put it in a wind tunnel you can put sensors in its wake to measure the pressure. By manipulating the fluid flow you can change the pressure. So low pressure on top and high pressure on bottom. Multiply that by the surface area and you get a force. Smaller force on top of the wing, lower force on the bottom of the wing. So the wing goes up. Of course theres some physics going on in the fluid that explains the change in pressure, but this is just a quick and simply-put explanation because I took a fat amount of zquil and am tired.

Basic mathematical literacy is a prerequisite to being able to use a calculator.
Literacy, sure. Like I can see say a formula for a median, or how to plot a simple linear regression, but I cannot actually do that math myself on paper without fucking it up. The more steps the worse it gets. I might genuinely have dyscalculia or something idk.
With a calculator though? No problem. Never any issues with doing budgeting or some basic statistics. If anything I'm kind of known as the math-sy one amongst my peers just because I know a bit more than an average person about statistics due to my interest in economics and politics, and a little bit about electricity from my hobby in electronics with breadboards and shit.
Heck I remember writing a calculator app for my mobile app dev class in my compsci bsc and one time testing it while hunting for a weird bug, a result looked wrong, but as it turns out it was actually me that was wrong, and the result was right.
In my cybersec MSc I got really fucked by them inexplicably making us do IP address calculations in binary, but then I can also count on my fingers in binary, and made a full adder circuit once.
Tomorrow I'll be calculating memory offsets to practice buffer overflows, but I still don't even know most of the multiplication table, and subtracting or adding double digit numbers takes me a minute in my head.

What? How is multiplying by 5 more convenient than any other number?

Not only in School, even at university I was taught the DNA structure was solved by Watson und Crick. But they stole data from Rosalind franklin and even openly admitted it years later.
Edison ivented the light bulb in the US. No, it was Tungsram in Hungary. Edison did employ him as a result though.
Bell invented the telephone. No, it was Edison labs. Bell stiole the patent from an Italian guy when he was working in the patent office.
Philco invented the TV set. Nothing to do with it, it was Edison-Marconi. The CRT controller was invented in the Soviet Union hence the Philco invention story. -
"You need to learn this because you won't always have a calculator on you!"
Yeah but its such a hassle to find, so...

How planes generate lift.
What doesn't help is that plane pilots are basically taught a different version of physics to spare them from liquid dynamics and to see the forces on an aerofoil as independent ones which makes it all pretty confusing for a layperson trying to get a basic understanding of both and marry the two

I was taught that the moon landing was fake.

Sure. You're very funny.
I was also taught this in school, along with many very unscientific things. When they eventually taught us about evolution (they had to because of national curriculum) they couldn't stop stressing how it was "just an outdated theory" and showed us additional videos which "disproved" it

Pluto is a great test for what types of person someone is.
If someone says Pluto is still a planet. They have a personality where they are immovable and can't accept scientific change.
If they do say pluto is a new kind of dwarf planet they arw more accepting of new information and belive in the scientific method.
It's a great quick test when meeting news people.
So presumably NASA is anti-science ?
Because they have redetermined that Pluto is a planet.

Dont know about the first two, but heart disease do. heart stroke happened to my mother and both her parents, her dad died from it. My fathers dad died of brain store and doctors say he heart is also weaken(mostly from smoking 30+ years)
