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

Hear about pluto? Pretty messed up huh?

Racism used to be a problem until Lincoln and MLK fixed it.

Some children are taught in school that God created the earth. Some of us were allowed to learn that humans cannot effect climate change, allowed to discuss it openly, and allowed to graduate with that idea without ever being corrected. Children are being taught today that slavery and colonialism were good things for some people.

I was taught that Pluto is a planet. How could they have been so wrong???

[–] [email protected] 17 points 1 day ago

It was false then but my seventh and eighth grade science teacher told us that blood was blue. My mom was a nurse so I knew that it was bullshit but was definitely confused because he was my science teacher.

I had a substitute teacher who saw the Swift Boat Veterans For Truth ads against John Kerry and repeated it to the class like it was 100% fact.

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.

[–] [email protected] 6 points 18 hours ago

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.

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.

@turnip

> It can cause dimensia

I'm sorry, what the fuck? And what is "dimensia"? Does it have anything to do with spacetime dimensions?

Yeah, you start seeing the full multiverse. It's crazy.

And don’t forget to floss! As soon as I learned that my gums donβ€˜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.

The United States operates on the principle of three co-equal branches of government, which check and balance each others power.

The myth that glass is a very thick liquid. It's actually much weirder than that. https://gizmodo.com/the-glass-is-a-liquid-myth-has-finally-been-destroyed-496190894

[–] [email protected] 3 points 15 hours ago

I tried to argue this with a science teacher who chose that specific material for a question about phases, and I assumed she was asking for this tricky reason. She marked me wrong and wouldn't accept my personal research on the topic as makeup. I was humiliated. I hope she's dead now.

I have one that was proven false, and then later re-proven true: the existence of the brontosaurus.

When I was in elementary school, we were taught that they existed, they were big, etc. Then, at some point while I was in college, I discovered that actually what we thought was a brontosaur was a brachiosaur or an apatosaur. And then, when my kids went to school and learned about the brontosaur, I discovered that actually, they did exist!

The moon was spun out of the same stuff as the earth. That was fact in the early years of my education. A few years later there were multiple theories: co development, captured a wandering planetoid, the Thea impact, and a fourth one I can’t remember but I think it was something dumb like planetary mitosis. By the time I graduated the Thea impact was considered the only viable theory.

By the time I was in school the Bohr model was already proven inaccurate, but was taught anyway because the orbital model is too esoteric for teenagers πŸ™„.

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."

[–] [email protected] 3 points 19 hours ago

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.

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.

[–] [email protected] 1 points 10 hours ago* (last edited 10 hours ago)

The only hallucinogen that lives up to D.A.R.E hype is DMT. Things like mushrooms and LSD will give funny visuals and make you think in different perspectives, but you're still "you" and still on Earth.

DMT though? You can straight up leave this reality and lose yourself if you take enough. You can see things and creatures that couldn't possibly exist. You can meet God, and live entire lifetimes before crashing back into reality 15-20 minutes later.

I was chucked into Christian school.

So... a lot of it.
