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.
Tiny photocell powered calculators used to be everywhere. There were “thin” ones to fit in your Costanza sized wallet, Mousepads with them built in, and my wristwatch in 6th grade had one with tiny rubber keys.
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.
I don’t think that would surprise anyone. The GOP has been a giant grift since at least Reagan. A loooot of people out there can’t tell when they’re getting scammed.
It’s one reason why educated voters tend to be further left on the political spectrum.
That's funny. I had a teacher do something like this but in the other direction. All the questions had answers that pretty much forced you right into the blue. Shit like "do you think homeless people should be given assistance or should homeless people be shot and dumped into the sea?" Or "I think everyone deserves to find love vs gay people are the spawn of Satan".
It is worth noting that I went to a very left leaning and notoriously "hippy" private school (against my will). I eventually managed to get expelled for smoking weed and not snitching on all my friends.
I don't think teachers really should be pushing their political or religious agendas no matter what. School is for learning core basics in various categories.
It's less that I don't want them mentioning anything that connects to politics and it's more about wanting them to just present information without any additional spin.
So "Trump has put tarrifs on x countries for x amount" vs "Trump has stupidly put x tarrifs on x countries because he's a hateful tyrant" or whatever. I think you get what I'm trying to say.
I have absolutely no problem with talking about politics as it's pretty much impossible to mention anything in history without it, but it can be done so in very different ways. I would prefer that teachers remain as neutral as they can while presenting only factual information on whatever political topics comes up.
Kinda how I wish the news would go back to facts first reporting as opposed to this current "rush the story out before we fact check anything and make the headline as polarizing as we can to generate maximum clicks. Who cares if we have to issue a correction later on page 97 in .5 size font (or at all) we just want clicks!" Type of "news" we have now.
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.
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.
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.
There's a weird thing here. I totally accept that the traditional tongue map is pseudoscience and debunked, but if you're paying attention to something like wine or good chocolate, letting it spread across your whole tongue really does seem change the flavor and bring new aspects to what you're tasting.
My subjective impression is that there is some effect to exposing the whole tongue to a stimulus, and I'd really like to understand it more - but when you search the web, you pretty much just get deconstructive articles about the old model, and not much about what might actually be happening.
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 “known” archaeology and anthropology from even just a couple decades ago.
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.
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.
When dealing with base 10 representations, multiplying by 10 is a simple matter of adding zeroes;
dividing numbers that end with a zero by two is (usually) an afterthought;
doing both operations in that sequence is (usually) equally trivial, the only effortful thing I have to do is adding or subtracting a multiplicand, once or twice or thrice.
It's not easier than having the result imprinted in my memory, but it cuts away ~ three quarters of the table.
Is it so bad to know your multiplication tables? It’s lowk a quality of life thing yknow. imo it’s just a good thing to know so you aren’t entirely reliant on the calculator for an answer.
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
Pluto is a great test for what type 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 and everything has to be how they first learned it.
If they do say pluto is a new kind of dwarf planet they are more accepting of new information and belive in the scientific method and love to be wrong. Since it means we learn something new.
I recently heard that they discovered hundreds of Pluto sizes "planets" beyond Pluto, so they had to decided do we add 100 more planets or just demote Pluto to planetoid and ignore the rest
Or the third option of they recognize that scientifically Pluto is a dwarf planet and no longer a 'full' planet, but they also anthropomorphize everything to an unhealthy degree and don't want to hurt the feelings of Pluto by saying it isn't a planet anymore
I know - can the person accept hundreds of planets and that ours is less special, or do they need to change a definition (including exceptions) to keep their world view.
Well, Pluto being reclassified as a dwarf planet doesn't really have anything to do with the scientific method. "Planet" is a manmade concept, we just changed the definition for that classification to avoid having to add the dozens of bodies we discovered since Pluto that would have also met the old definition.
Did we conclude that, I thought its still heavily debated.
Some argue in the 50s and 60s the US was spending Europe's gold to build highways and infrastructure, gifting Americans the wealth with a continuation of the new deal, they then defaulted in 1971 as inflation eroded foreign debt owed.
Some feel some form of debt accrual is how we derive such a consumption focused standard of living, which is misallocated capital that ends in someone holding the bag when it can't realistically be paid back, or when population doesn't grow fast enough like in Japan or most of the developed countries.
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.
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.
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.
This really depends on what exactly you're ingesting and how much of it. Because it can definitely be crazier than Alice in Wonderland. Depending on factors.
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.
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.
I've been working on my hand writing, and these kids can't read cursive. I worked real hard and my young coworkers were like bart.Bart. I developed my own short hand during college. My notes might as well be encrypted. I can't be old! I'm still with it!
My handwriting turned around after I got a fountain pen. I went from doctor to pre-med handwriting. Having to think more about how to form the letters has me taking my time. No need to rush when I'm writing with a fancy pen full of cool ink.
The appendix is a vestigial organ that doesn't actually do anything in humans. (It might still fit the definition of vestigial, but it's far from useless and we keep learning more about how valuable gut health is.)
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
Their belief system is based on an a being that can't be sense that banished people to infinite torment for following instincts that he designed them with, then sent part of himself to be tortured and killed as a sacrifice to make up for a curse he put on them, but only if you it was necessary. A ridiculous age of the earth is hardly the craziest thing schools like this teach.
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 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.
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.
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.
Source: Im getting a PhD in aerospace engineering
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?
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
Haven't seen anybody post this but how gender and sexuality is, schools are so fucking about straight mom and dad only relationship and nothing else. Man and wife bullshit when there's infinite amounts of gender and sexuality and diversity out there. Fuck I hate Amerikkka
I am from germany. Sex ed is not just manditory but also part of normal lessons all two years. The body, genetics, sex itself and how a baby is made and how protection and STDs work and which are there next to condom and pill
Funnily enought i wasnt present the whole male sex ed part so idk if they talked about queernes. Being in a psychiatric hospital they only had german, math, english, classes so litterly only the essentials
I went to a trades school which offered IT computer systems as a 2 year diploma. Fast track to a job back in the early 2010s. That path would never get you into IT today lol
The specific class I mentioned was windows system administration
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.
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 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."
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.
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.
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!
"This is the best time of your life, it will never be as easy."
I wasted more time at school than at work and I didn't have Fridays off, so that was a lie.
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.
In my college Econ 101 class I was taught that "economic liberalism" would lead to political liberalism. I knew that was a myth back then, but my professors insisted. Twenty years later we've got economic nationalism and political fascism taking over everywhere.
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.
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.
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
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.)
Junk DNA is still a thing - some parts of thr genome are verifiably junk, and the rest is just "unkown". It's just that some of the "unknown" bits back in the day have now been found to actually be useful. At least this is my understanding as a non expert.
Previously it was thought that non-coding sequences were junk, and enormous numbers like 99% were thrown around at the time. Later, we found out that more and more of the non-coding regions actually do various other things, and the scope of junk DNA got narrower as years went by. Nowadays, you don’t really hear that term much, because future scientists have a tendency of discovering new functions for sequences that were previously thought of as non-functional. There’s also debate as to where do we draw the line.
As usual, biochemistry is a fast moving target, and people have gotten cautious about these things. As more and more is discovered, older notions are updated or even thrown away.
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 🙄.
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
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.
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.
I learned that it’s not ok to be intelligent but completely incapable of remembering to do things or remembering the things that the teachers thought it was important for me to remember.
I dont remember anything that was proven false.
I remember i butted heads with my history teachers constantly. Having history as my hyperfocus of my autism, and hyperactive talking from adhd, i had to correct one teacher a lot.
Saying the classic "the HRE was neither holy nore roman nore an empire" but nobody called it that back then. It was known as just "the empire". And the "holy" part was due to shenanigans with the pope, and it defenetly was an empire in the sense of span. Yes everything was autanomouse, but it was an empire by size of who swears loyalty.
I learned more that the things i back then saw as useless and "why are we being tought that" is actually really important.
Example: text analysis if grammer, way of phrasing things, wether the autor clearly frames things threw choice of words, if it is a story, news article or comment
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)
For two and three, even if there weren't a genetic component, the lifestyle and dietary habits of a family absolutely do impact the next generation of the family. Learned behaviors that increase the risk of alcoholism or heart disease absolutely count as "runs in the family". Further, "runs in the family" never meant "everyone in the family absolutely has it".
(None of this directed to the comment I'm replying to, just continuing the thought of the comment.)
I dont follow, if you are talking about lifestyle choices there is really inst any similarity, neither in weight, eating habits or work or living conditions .My grandma and grandpa lived in a village until there 40s. Also heart disease is not the only genetic disease in the family. Both my mom and her mom had ovary cancer.Diabetes runs in the family both type 1 and type ,both sets of grandparents and both there siblings and parents,both sets of aunts and uncles, me and my sisters plus alot other relatives. My grandma(father's side) had bipolar, so does my uncle so does my sister and all of this is just counting genetic disease and not everything else like baldness(both me and my uncle started at 16), i have a single string of blonde hair growing in exactly the middle of my forehead and so does my aunt's daughter(our moms are twins) and we both have a baby tooth that steal didnt follow at our 20s with the adult one growing behind them
The question wasn't wether there are inheritable health issues, diabetes, some cancer, etc are demonstrated to have a heredity component. I'm not even arguing that heart disease 'isn't' hereditary, I'm just saying that in the context the argument, you saying that several of your family members had it doesn't prove that specific thing is inherited. Everyone does of something and the fact that you can find 3 to 5 people in your lineage that died of that does point to it being inherited.
he fact that you can find 3 to 5 people in your lineage that died of that does point to it being inherited
It does though? like it doesn't have to be 100% beyond a shadow of a doubt genetic like say type 1 diabetes, and with everything else it most likely is
are demonstrated to have a heredity component
I am of the believe that most health issues are genetic, be it mutation or hereditary. I haven't looked into it much but from experience ppl tend to believe most diabetes are caused by being overweight(or general life style) and that's no the case in my experience. I feel believing its life style choices hurts ppl more in the long run than it helps(the number of arguments i got with non-diabetes ppl about my own diabetes for example)
But also like what does this have to do with anything?
Heart disease runs in families. Nope.
the OG commenter said it doesn't runs in families and we both agree it can, why does it matter whether it runs specifically in my family or not. People with health issues know about their own medical history, when someone tells you heart disease run in the family, take them at their word(plus they probably talked to doctors and what not)
It only 'matters' to the extent that OP claimed it doesn't run in families, and you seemed to be claiming it does 'because' you had 3 -5 relatives that died from it. All I'm saying it's that anecdotal evidence doesn't refute an assertion like that.
If you'd said 'it does run in families and here is a statistically significant sampling across variable x, y and z' i wouldn't be arguing, I'd likely be reading an article about it. But it's worth pointing out when people use unscientific reasoning in a forum where other people might be influenced by an argument if no one calls out the fault in logic.
"You need to learn this because you won't always have a calculator on you!"
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.
wat
Tiny photocell powered calculators used to be everywhere. There were “thin” ones to fit in your Costanza sized wallet, Mousepads with them built in, and my wristwatch in 6th grade had one with tiny rubber keys.
It was a magical time till be alive. 5318008
Yep, back in the 90s they were in some places. My local supermarket had one like this, except without the annoying ad on the left side.
The same was told to me even as everybody already had mobile phones with calculators in them or even iPhones
Basic mathematical literacy is a prerequisite to being able to use a calculator.
I feel have super power by being to calculate accurate tips without needing to crack out my phone.
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.
the quiz:
Seems like the teacher was ahead of their time, or way behind it depending on whether they drew inspiration from Moms for liberty or Adolf Hitler.
Ironically, I have read that there was a study that found that the most gullible kids in elementary school grow up to be republican. I'm not kidding.
I don’t think that would surprise anyone. The GOP has been a giant grift since at least Reagan. A loooot of people out there can’t tell when they’re getting scammed.
It’s one reason why educated voters tend to be further left on the political spectrum.
That's funny. I had a teacher do something like this but in the other direction. All the questions had answers that pretty much forced you right into the blue.

I blame Reagan.
Political alignment tests have a serious case of intentional sampling bias

Yeah, a lot of people seem to become teachers because they like being in a room full of people who won't question them.
That particular teacher in the story was also let go at the end of the year, though, related to her treatment of students. It was kind of dramatic.
There's a weird thing here. I totally accept that the traditional tongue map is pseudoscience and debunked, but if you're paying attention to something like wine or good chocolate, letting it spread across your whole tongue really does seem change the flavor and bring new aspects to what you're tasting.

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
The multiplication table is still fact even if you have a calculator.
6 x 6 mothefuckers. Y'all tell me that didn't immediately form "36" in your brain.
I was thinking of a bed for some reason
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.
What? How is multiplying by 5 more convenient than any other number?
When dealing with base 10 representations, multiplying by 10 is a simple matter of adding zeroes;
dividing numbers that end with a zero by two is (usually) an afterthought;
doing both operations in that sequence is (usually) equally trivial, the only effortful thing I have to do is adding or subtracting a multiplicand, once or twice or thrice.
It's not easier than having the result imprinted in my memory, but it cuts away ~ three quarters of the table.
Is it so bad to know your multiplication tables? It’s lowk a quality of life thing yknow. imo it’s just a good thing to know so you aren’t entirely reliant on the calculator for an answer.
I need to use multiplication at work every single day, it's extremely handy to remember them.
Study and work hard will make you successful.
Depends on your definition of successful
Broadly speaking, failing to put in effort does tend to lead to worse outcomes.

I would say "cursive is how adults write, you'll need to know it", but that wasn't true then either.
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
cursive sucks ass. im not reading that garbage
I actually use it myself sometimes when taking notes. It's just the natural way to write for me. It's faster and more space effective.
I cant even read my own cursive from back then.
Now i know how my teachers felt and why they constantly told me i write unreadablely. Used to be able to read it fluently lol
PLUTO IS A PLANET!
I thought it was Mickey Mouse's dog 🤔!
IT'S BOTH AT THE SAME TIME
What? As in Schrödinger's cat? Interesting!
Why does a mouse own a dog? And how come the mouse is also friends with another dog? What’s going on there?
Ok Jerry.
This was my first thought as well!
Pluto is a great test for what type 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 and everything has to be how they first learned it.
If they do say pluto is a new kind of dwarf planet they are more accepting of new information and belive in the scientific method and love to be wrong. Since it means we learn something new.
It's a great quick test when meeting new people.
I recently heard that they discovered hundreds of Pluto sizes "planets" beyond Pluto, so they had to decided do we add 100 more planets or just demote Pluto to planetoid and ignore the rest
Yep https://en.wikipedia.org/wiki/Eris_%28dwarf_planet%29
Eris? Didn't Sephiroth kill her?
Or the third option of they recognize that scientifically Pluto is a dwarf planet and no longer a 'full' planet, but they also anthropomorphize everything to an unhealthy degree and don't want to hurt the feelings of Pluto by saying it isn't a planet anymore
I know - can the person accept hundreds of planets and that ours is less special, or do they need to change a definition (including exceptions) to keep their world view.
Well, Pluto being reclassified as a dwarf planet doesn't really have anything to do with the scientific method. "Planet" is a manmade concept, we just changed the definition for that classification to avoid having to add the dozens of bodies we discovered since Pluto that would have also met the old definition.
Did we conclude that, I thought its still heavily debated.
Some argue in the 50s and 60s the US was spending Europe's gold to build highways and infrastructure, gifting Americans the wealth with a continuation of the new deal, they then defaulted in 1971 as inflation eroded foreign debt owed.
Some feel some form of debt accrual is how we derive such a consumption focused standard of living, which is misallocated capital that ends in someone holding the bag when it can't realistically be paid back, or when population doesn't grow fast enough like in Japan or most of the developed countries.
I was chucked into Christian school.
So... a lot of it.

the bullies have weird families with 4 stupid looking kids, but im still getting laid and i have no debt
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.
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.
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.
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?
This really depends on what exactly you're ingesting and how much of it. Because it can definitely be crazier than Alice in Wonderland. Depending on factors.
That blood is actually blue until it gets in contact with air
Easy to proof: Vaccumated capsule to draw blood.
No contact with air and still red.
I remember my science teacher in seventh grade saying this. I was just very confused because my mother who was a nurse said it was just a dark red.
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.
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?
Along with Franklin, I believe a grad student, Raymond Gosling. I feel I'm forgetting about another big contributor, but who knows.
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.
Oxford comma for life!
I was taught to use the Oxford comma by my parents, Ayn Rand and God. I had a strange upbringing.
It’s useful, helps with the flow of the ideas, and is more like the sentence is spoken.
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.
Thank you for your continued support of the Oxford comma.
Oh I didnt think of the Pluto thing! Thats a good one
I've been working on my hand writing, and these kids can't read cursive. I worked real hard and my young coworkers were like bart.Bart. I developed my own short hand during college. My notes might as well be encrypted. I can't be old! I'm still with it!
My handwriting turned around after I got a fountain pen. I went from doctor to pre-med handwriting. Having to think more about how to form the letters has me taking my time. No need to rush when I'm writing with a fancy pen full of cool ink.
-Coequal branches of government
-Separation of Church and State
-Life terms for SCOTUS ensures political impartiality
-The second amendment was so that we could defend ourselves (see: redcoats)
-Bohr system
That CO2 makes up 0.03% of the atmosphere. But it was true then.
When was that?
Late 70s early 80s.
The appendix is a vestigial organ that doesn't actually do anything in humans. (It might still fit the definition of vestigial, but it's far from useless and we keep learning more about how valuable gut health is.)
My appendix came damn close to killing me. I vote “not valuable”. :)
The asteroid that killed the dinosaurs was seen as just one of several possible theories, rather than accepted fact.
My favourite one was that the earth is 6000 years old
Where did you go to school? Everybody knows its 2025 years old.
I am a Christian and I don't believe that. I could go on at length about how the Bible doesn't support that idea.
It's called a Christian school, i wouldn't recommend it
They exist. There's one in my town.
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
I'm not even American mate
Funny? Do you think religious schools don't exist?
Shouldn't exist. That's different.
Their belief system is based on an a being that can't be sense that banished people to infinite torment for following instincts that he designed them with, then sent part of himself to be tortured and killed as a sacrifice to make up for a curse he put on them, but only if you it was necessary. A ridiculous age of the earth is hardly the craziest thing schools like this teach.
Religious schools exist!
Going to college was guaranteed success in life.
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 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.
How planes generate lift.
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.
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 wing experiment with hundreds of pressure sensors shows lower pressure on top and more on bottom.
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.
Source: Im getting a PhD in aerospace engineering
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?
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
Haven't seen anybody post this but how gender and sexuality is, schools are so fucking about straight mom and dad only relationship and nothing else. Man and wife bullshit when there's infinite amounts of gender and sexuality and diversity out there. Fuck I hate Amerikkka
I am from germany. Sex ed is not just manditory but also part of normal lessons all two years. The body, genetics, sex itself and how a baby is made and how protection and STDs work and which are there next to condom and pill
Funnily enought i wasnt present the whole male sex ed part so idk if they talked about queernes. Being in a psychiatric hospital they only had german, math, english, classes so litterly only the essentials
can you be more specific
My sysadmin professor told me to not learn about tape backups because they are going away soon
Like 3 years later ransomware was invented
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
can i have a job at your place
No but look into datacenter night shift work. Where i am nobody wants that shift. Working in a datacenter is pretty fun
interesting. what sort of resumes are you looking for in a data center? security clearances? i have a devops resume, AWS, Linux etc.
Pretty much that but also ability to use tools and basic knowledge of air conditioning etc
how do I find a data center role in particular? normally i am searching "Linux" to get devops roles.
holy crap a sysadmin class? that is wild, son. i must be an old man
I went to a trades school which offered IT computer systems as a 2 year diploma. Fast track to a job back in the early 2010s. That path would never get you into IT today lol
The specific class I mentioned was windows system administration
We had one in the lab though and just ignored it
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.
Making grimaces and being told that your face may remain that way if you don’t stop making them… 🤡
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 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."
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.
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.
We were each given like a quarter teaspoon of grounds and a toothpick.
A tiny amount on like a q-tip. Not enough to effect anything except flavor
Supersize me was fake and tonsils are not a useless byproduct of evolution.
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
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!
"This is the best time of your life, it will never be as easy."
I wasted more time at school than at work and I didn't have Fridays off, so that was a lie.
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.
Gravity Waves didn't exist according to my highschool science teacher
Racism used to be a problem until Lincoln and MLK fixed it.
In my college Econ 101 class I was taught that "economic liberalism" would lead to political liberalism. I knew that was a myth back then, but my professors insisted. Twenty years later we've got economic nationalism and political fascism taking over everywhere.
I was taught that the moon landing was fake.
Jesus Christ, how? Why? I'm so sorry
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.
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.
https://en.m.wikipedia.org/wiki/Skeletal_fluorosis
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?
@Nikls94
Yeah, you start seeing the full multiverse. It's crazy.
Dementia is what they mean.
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
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.)
Here's video evidence from a documentary I watched abouy what happened and why they ended up with 10.
Junk DNA.
Junk DNA is still a thing - some parts of thr genome are verifiably junk, and the rest is just "unkown". It's just that some of the "unknown" bits back in the day have now been found to actually be useful. At least this is my understanding as a non expert.
Previously it was thought that non-coding sequences were junk, and enormous numbers like 99% were thrown around at the time. Later, we found out that more and more of the non-coding regions actually do various other things, and the scope of junk DNA got narrower as years went by. Nowadays, you don’t really hear that term much, because future scientists have a tendency of discovering new functions for sequences that were previously thought of as non-functional. There’s also debate as to where do we draw the line.
As usual, biochemistry is a fast moving target, and people have gotten cautious about these things. As more and more is discovered, older notions are updated or even thrown away.
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 🙄.
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.
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.
I learned that it’s not ok to be intelligent but completely incapable of remembering to do things or remembering the things that the teachers thought it was important for me to remember.
Hear about pluto? Pretty messed up huh?
You know that's right!
I was taught that Pluto is a planet. How could they have been so wrong???
I dont remember anything that was proven false. I remember i butted heads with my history teachers constantly. Having history as my hyperfocus of my autism, and hyperactive talking from adhd, i had to correct one teacher a lot.
Saying the classic "the HRE was neither holy nore roman nore an empire" but nobody called it that back then. It was known as just "the empire". And the "holy" part was due to shenanigans with the pope, and it defenetly was an empire in the sense of span. Yes everything was autanomouse, but it was an empire by size of who swears loyalty.
I learned more that the things i back then saw as useless and "why are we being tought that" is actually really important. Example: text analysis if grammer, way of phrasing things, wether the autor clearly frames things threw choice of words, if it is a story, news article or comment
Never heard this before!
I just realized that this was about things learned in school. Nevermind 😂
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.
What
Mantle convection as a primary driver of tectonic plate movement
Everything about Christopher Columbus.
There is no such thing called umami.
Well there is, its just not a flavor like salty, its a way of taste from what i learned. Idk how to discribe it myself
You can describe it as umami
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)
For two and three, even if there weren't a genetic component, the lifestyle and dietary habits of a family absolutely do impact the next generation of the family. Learned behaviors that increase the risk of alcoholism or heart disease absolutely count as "runs in the family". Further, "runs in the family" never meant "everyone in the family absolutely has it".
(None of this directed to the comment I'm replying to, just continuing the thought of the comment.)
That's like saying black lung runs in families because your family all worked in the mines.
I dont follow, if you are talking about lifestyle choices there is really inst any similarity, neither in weight, eating habits or work or living conditions .My grandma and grandpa lived in a village until there 40s. Also heart disease is not the only genetic disease in the family. Both my mom and her mom had ovary cancer.Diabetes runs in the family both type 1 and type ,both sets of grandparents and both there siblings and parents,both sets of aunts and uncles, me and my sisters plus alot other relatives. My grandma(father's side) had bipolar, so does my uncle so does my sister and all of this is just counting genetic disease and not everything else like baldness(both me and my uncle started at 16), i have a single string of blonde hair growing in exactly the middle of my forehead and so does my aunt's daughter(our moms are twins) and we both have a baby tooth that steal didnt follow at our 20s with the adult one growing behind them
plus we aren't from America.
The question wasn't wether there are inheritable health issues, diabetes, some cancer, etc are demonstrated to have a heredity component. I'm not even arguing that heart disease 'isn't' hereditary, I'm just saying that in the context the argument, you saying that several of your family members had it doesn't prove that specific thing is inherited. Everyone does of something and the fact that you can find 3 to 5 people in your lineage that died of that does point to it being inherited.
It does though? like it doesn't have to be 100% beyond a shadow of a doubt genetic like say type 1 diabetes, and with everything else it most likely is
I am of the believe that most health issues are genetic, be it mutation or hereditary. I haven't looked into it much but from experience ppl tend to believe most diabetes are caused by being overweight(or general life style) and that's no the case in my experience. I feel believing its life style choices hurts ppl more in the long run than it helps(the number of arguments i got with non-diabetes ppl about my own diabetes for example)
But also like what does this have to do with anything?
the OG commenter said it doesn't runs in families and we both agree it can, why does it matter whether it runs specifically in my family or not. People with health issues know about their own medical history, when someone tells you heart disease run in the family, take them at their word(plus they probably talked to doctors and what not)
It only 'matters' to the extent that OP claimed it doesn't run in families, and you seemed to be claiming it does 'because' you had 3 -5 relatives that died from it. All I'm saying it's that anecdotal evidence doesn't refute an assertion like that.
If you'd said 'it does run in families and here is a statistically significant sampling across variable x, y and z' i wouldn't be arguing, I'd likely be reading an article about it. But it's worth pointing out when people use unscientific reasoning in a forum where other people might be influenced by an argument if no one calls out the fault in logic.
