What was a fact taught to you in school that has been proven false during your lifetime?
-
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 was exactly, but it was pretty severe.
I remember getting detention on first grade for telling my classmate that a whale had beached here in finland. It happened, it was on the news. Same thing again after I told my classmate about some asteroid that is going to kill us all. On 6th grade the whole class was given detention for not having music books with us because the teachers had decided to change the schedule that morning.

tape backups are definitely still a thing. it's one of the cheapest ways to store a shitload of data for a long time
I spend a portion every day removing tapes, shipping them offsite and inserting new tapes
Annoying but must be done

Idk you can only ‘learn’ them if you have one and even the shittiest tape drive I could find as a consumer doesn’t help me at all with a tape library. We have our tape admin (=our architect) who we thank god every day for because we didn’t have to bother with it. Now he’s retiring this year.. F
We had one in the lab though and just ignored it

Physical Vs chemical changes.
It was typically taught that physical changes are differentiated from chemical changes because they could be "undone" or that they had "no chemical reaction." Which was very confusing, because you can't uncut paper, and dissolving stuff in water clearly results in different chemicals being produced, yet both were examples of physical changes (actually the latter is sometimes taught as a chemical change). Furthermore, most chemical changes are actually reversible.
It has since been recognised that this classification is BS, and most changes actually exist on a continuum.
I distinctly remember my fifth grade teacher trying to pull that.

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."

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

I am teaching this next week. It is sometimes painful how simplified we have to make content for middle school. You are expressing what science teachers hope for from students. You were curious enough to explore further and ask questions, the true purpose of science.

Gene sequencing wasn’t really a thing (at least an affordable thing) until the 2010s, but once it was widely available archaeologists started using it on pretty much anything they could extract a sample from. Suddenly it became possible to track the migrations of groups over time by tracing gene similarities, determine how much intermarrying there must have been within groups, etc. Even with individual sites it has been used to determine when leadership was hereditary vs not, or how wealth was distributed (by looking at residual food dna on teeth). It really has revolutionized the field and cast a lot of old-school theories (often taken for truth) into the dustbin.
Wonder how many new ones it's creating.

Sure. You're very funny.
Funny? Do you think religious schools don't exist?

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!

Cursive is such a bad way to write. I used to have to decipher sloppy cursive notes on how to check airplane fixtures. I even learned it in school!
Good cursive flows very nicely. I got to watch my grandmother's handwriting deteriorate as the dementia and Alzheimer's took her. Was always amazed for well she wrote when i was younger, but her handwriting turned pretty incomprehensive as her brain was eaten away by the disease

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.I'm having a hard time fund evidence that AG Bell stole anything from an Italian, do you have any more information to keep me look this up?

There are 10 Commandments.
No - there's 14.
613 mitzvot! ± a couple hundred, depending on whether you're a Kohen, live in Israel, if the Temple has been rebuilt, or are the first-century sage Hillel (in which case there's one mitzvah and 612 articles of commentary.)
