I was taught that Jupiter had 17 moons, Saturn has 12 and Pluto has 1. Many more have been discovered since.
Then there’s the whole “different areas on your tongue taste different flavors.” Like you only taste sweet with the tip of your tongue, the middle tastes salty, etc. I remember being given various substances by my fifth grade teacher like sugar, coffee, lemon juice, table salt etc. and we tried putting them on different areas of our tongues and we were like “…no, we taste everything everywhere.”
Were you guys eating coffee grounds in your 5th grade science class? Your next teacher either hated it because you guys were bouncing off the walls or loved it because you were all wide awake and paying attention.
A tiny amount on like a q-tip. Not enough to effect anything except flavor
We were each given like a quarter teaspoon of grounds and a toothpick.
I was always so confused by the tongue areas because it never seemed to work for me. Especially sweet, I tasted sweet far more at the back than on my tip.
The United States operates on the principle of three co-equal branches of government, which check and balance each others power.
This is painful.
Basically everything I can recall being told in D.A.R.E program classes (war on drugs era propaganda taught in public schools in the USA) was utter nonsense and fabricated bullshit. After actually having personal experience with most of the substances they vilified, none of the effects - good or ill - are what I was taught in that ridiculous program.
On the contrary, some of the fear tactics they used made me curious to investigate on my own. The breathlessly scared rural teacher describing the mind bending effects that “magic mushrooms” was supposed to have sounded fascinating to teenage me. In reality, they are very fun and therapeutic to use, but nothing like the wild Alice in Wonderland mind journey they made it sound like it would be.

Drugs Are Really Excellent?
Supersize me was fake and tonsils are not a useless byproduct of evolution.
Mantle convection as a primary driver of tectonic plate movement
A huge number of aspects of the US’s geopolitical enemies, and its own mythologization of the Founding Fathers and early settlers.
There was also a really bad political test with liberalism on the left and conservativism on the right, and we had to take a test and put what we got in front of everyone, which was very strange.
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
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.

Edit: I had to do this in a wind tunnel during one of my undergrad courses. It was fun playing with the wind tunnels, would recommend
hm, I just read through a few publications pertaining the Navier–Stokes equations and the scientific community still didn’t seem to find out why they’re not 100% accurate even in lab conditions because of threedimensional interference, is that correct?
The wing experiment with hundreds of pressure sensors shows lower pressure on top and more on bottom.
NASA has a webpage on aeronautics that says lift is the mechanical force created by a solid object turning a flow of liquid or gas. They also have an equation for calculating lift for any solid object/fluid combo.
The D.A.R.E. program.
We congratulate drugs for winning the war on drugs.
I’m addicted to dopamine, and I’ll take any drug I can to get more of it.
“Those bullies will be working at a gas station while you’ll be the boss!”
the bullies have weird families with 4 stupid looking kids, but im still getting laid and i have no debt
Allergies are entirely genetic. Apparently they ain’t or so I hear but it’s a bit above my paygrade biology wise
Epigenetics in general really messed with what a lot of people learned in school
TIL new word. Fascinating. Thanks!
That glass is a liquid at room temperature, just a very viscous one so it doesn’t appear to flow. It’s not. It’s not a crystalline solid so it has an internal structure similar to a liquid, but the structure is definitely solid at room temperature because the components are not capable of moving relative to each other like a liquid would.
It’s also not the reason church windows are thicker at the bottom, a common myth that my ex-colleague with a PhD in polymer chemistry(!) somehow bought into
Glass not being a polymer still does suggest they’re talking out of turn
Not a polymer but an amorphous solid like many polymers; I believe she popped that nugget while explaining crystallinity and glass transitions. She was quite knowledgeable otherwise but that little false factoid must have slipped through.
I was taught that Pluto is a planet. How could they have been so wrong???
Everything about Christopher Columbus.
That fluoride and vaccines are bad for you… tbh, I only believed it for 2-3 weeks until I did my own research, but it was a frightening clarification. Didn’t believe that teacher a single word after that.
I think people underestimate the problems with teeth hygiene. It can cause dimensia, so teeth should be brushed before you eat, though avoid mouth wash.
And don’t forget to floss! As soon as I learned that my gums don‘t bleed because of the metal thing, but because food between my teeth decays and that decaying decays my gums, turning it all into poop, I started to floss every second day.
Why should I avoid mouth wash though? My routine is floss - mouth wash - brushing
Just the cancer causing it does. I’d read a study on it one time, I believe it’s accurate.
Mouthwash cancer?
A lot of mouthwash uses alcohol, which does cause oral cancer
Yeah, you start seeing the full multiverse. It’s crazy.
Fluoride can be bad for you, just at much higher doses than they put in water supply. It can cause issues with bones and neurological development. Again, only in very high doses over a long time. It happens a lot in poorer countries where they can’t treat well water.
Making grimaces and being told that your face may remain that way if you don’t stop making them… 🤡
