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

[–] theksepyro@lemmy.ml 2 points 6 days ago (1 children)

Glass not being a polymer still does suggest they're talking out of turn

[–] Krelis_@lemmy.world 1 points 5 days ago

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.

Hear about pluto? Pretty messed up huh?

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

"You need to learn this because you won't always have a calculator on you!"

[–] Moobythegoldensock@lemm.ee 45 points 1 week ago (4 children)

That wasn’t so much a β€œfact” 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.

That I was a republican. The teacher gave out this political alignment quiz that was incredibly biased asking things like "do you like lower taxes or higher taxes?" and "do you like more freedom or less freedom?" All the questions basically lead you to the same answers. So the entire class basically had the same result.

This was in middle school so I wasn't even politically engaged yet. I didn't realize how crazy this was until years later.

That tastes have specific regions on the tongue. We actually had to protest when that shit was taught at our son's elementary school. Don't know if it came up for our younger daughter.

Poor kids at school had old atlases where Germany was still separated. But I guess that's just obsolete and not false knowledge.

[–] CanadaPlus@lemmy.sdf.org 42 points 1 week ago* (last edited 1 week ago) (2 children)

Yeah, I remember that one. We even did an experiment to "prove" it. I was like, "I kinda taste it everywhere". I don't remember what the punishment for that one was exactly, but it was pretty severe, and I didn't do anything wrong.

Trickle down economics (well, it's not like there was a time when it was true)

[–] will_a113@lemmy.ml 65 points 1 week ago (3 children)

That humans came out of Africa once and then settled the rest of the world. In reality there was a constant migration of humans in and out of Africa for millennia while the rest of the world was being populated (and of course it hasn’t ever stopped since).

I love how much DNA analysis has completely upended so much β€œknown” archaeology and anthropology from even just a couple decades ago.

Taste buds are arranged by flavor in four sections of the tongue. Complete load of horseshit.

Multiplication tables (I still know them mostly). I have a calculator on damn near every device now.

Things will always get better <-- this one is the biggest lie of them all

[–] itsworkthatwedo@sh.itjust.works 34 points 1 week ago (5 children)

The multiplication table is still fact even if you have a calculator.

I would say "cursive is how adults write, you'll need to know it", but that wasn't true then either.

I was taught the Philippines was a US territory. I just learned last night that hasn’t been true since 1946. I went to school in the 90s.

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.

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.

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.
