My sixth grade science teacher thought she was letting us all in a cool fact when she said the gravity holding us on earth was actually centrifugal force. Makes me wonder what else I was told was false. I made a model of a wormhole but with all dimensions shifted down by one so we could visualize bent space as 2d. She really didn’t get it. I think in both cases she had trouble constructing stuff in her mind. Being unable to reason why it cannot be centrifugal (gravity force felt by objects on earth is pointing opposite direction from centrifugal) is probably a more general problem for her. She was real nice though. And taught us how to experiment. I turned out okay, and learning that adults don’t know all the answers is as important as anything else we learn.

My aunts MIL (who lives with them) has almost no proprioception due to a series of major strokes. Thus has caused her extreme anxiety. She broke her ankle recently and my uncle had to pick her up from a wheelchair and literally pivot her to sit her on a toilet. I was there helping and dear god, what happened next... She screamed. Not a little gasp or a single loud exclamation. Nope, she screamed in abject terror for over 10 minutes. Just kept screaming we were murdering her. We had huge issues with her at the hospital that next week. We kept trying to tell them that they can’t raise/lower the head of the bed. They needed to hand her the remote and tell her to do it, but they refused. So they’d move her bed with no warning and she’s clutch at the rails and scream in terror and the nurses would then get mad at her. It was horrible just witnessing it! Thankfully after a week she moved to a rehab facility and after I warned them about the proprioception issues, they instantly went to asking her to move herself. They also called in PT/OT for an extra session each day just to address that issue. And they called her doctor and told him to triple her anxiety drug- which they did do and she’s slowly becoming less terrified. She still hates when people push her wheelchair, though. You can push her forwards at the pace of a dead snail and she screams that you’re going to fling her forward, out of the seat, and she’s going to land 50’ away. I’m the only one she truly trusts to push her slow enough but I’m disabled myself and use forearm crutches most of the time, so I can only help with things like moving her 10’ from her bedroom to her bathroom (I can shuffle that far without falling).

You can't fault people teaching in grade school. Most aren't experts in their field, they are only going by the book. That of course opens up the possibility of being unable to teach an individual. I once witnessed a fellow student in my class who just wasn't getting it and the teacher was unable to explain what was being taught in any other way than what he had just explained. After enough questions from my classmate I finally understood what he was missing so I gave my explanation, the teacher followed up with "right, what he said", and the class was able to carry on. Also I never liked the use of "falling" in the "orbit" explanation. I feel like that could lead to further confusion when giving the explanation to some individuals. And I always assumed thermoception, proprioception, and equilibrioception were just part of the sense of touch.

Slight inaccuracies: Part 1: Astronauts in orbit have *not* done all their acceleration already. When you are in orbit at a constant speed, you're still accelerating under gravity. Your speed is constant, but velocity changes because your direction changes as you move around the Earth. However, that doesn't mean it isn't an inertial reference frame. Freefall is an inertial reference frame, but standing static on the ground isn't.

Almost all primates have 3 cone types, letting us distinguish between red and green with amazing regularity, which is important when you want to eat ripe, red fruit and leave the green ones until next week. Unfortunately, our 3-cone vision really only works in bright light, so most primates will hunker down for the night when we can't see anything, up in a tree away from most predictors and fall asleep, which we have evolved to be a great time to let immune functions operate without all the muscles using up all the energy.

How about this theory? Space-time _is_ gravity? Increasingly _warped_ space-time produces increasing effect of gravity (objects moving along parallel lines that join on a warped surface.) It's certainly no worse than 2:43 "the astronauts are falling at the speed of gravity." There are 2 major things wrong with Hank's statement. Gravity is not a speed, it's acceleration. And, it's not even acceleration because there is no Force (The only force is the ground pushing up). Second, Astronauts are not "falling", they are traveling on straight lines parallel to the earth in its straight line, and the parallel lines intersect on a curved space-time surface. (this from a guy who has a highly viewed KZitem video channel! :( The gravity field IS spacetime. How would you prove / disprove that?

When I was in high school, a couple friends and I looked at the Bohr model and decided that our solar system was actually an atom of fluorine (there were still nine planets back then). We further hypothesized that our fluorine atom was part of a molecule of Freon in someone's refrigerator. Daylight happened when they opened the fridge door and the light came on. We were wishing there were ten planets because then we could be a neon atom in a sign over a bar. (Hey, weird kid, weird grownup. What can I say?)

I think Sci-Show's debunked that. And just about every other science channel or indeed, factoid-spitting channel I've seen. I never really learned where that idea came from, though. No explanation has ever gone beyond basically saying, "some Swedish guy was dumb." No one ever can seem to say what made that researcher think that, or what fallacies were present in his research, or perhaps what biases led him to want to publish those results. It's kind of annoying, really, how little you can hear about when science went wrong, and what leads people to faulty conclusions. A lot of it doesn't go any further than, "this dope thought this, but we, the smart real scientists, tried that experiment and didn't find that result, so the other guy is wrong, and probably a dummy". People seem to be too preoccupied with saying, "we're right, he's wrong, neener neener" to actually give insight as to ways science can go wrong, and what sort of traps scientists can fall into, which I think is a missed opportunity for a pretty interesting topic.

I did have a teacher who explained the atom model is simplified to fit on the printed page, and that the reality is the electrons are flying about in every direction, changing levels, but that in essence the levels depict it abstractly and the numbers in the shells are correct. I was probably 1 of 2 people who understood that. Being that it was 1971 now I wonder what school he went to that taught that subject in an advanced manner. It may have been a particular interest that drove him to extra classes in a subject he fulfilled requirements for years before, and additional reading over the years since. I do that, I read lots of science stuff, especially space stuff, and read just about anything ever written about cars, trucks, off road vehicles (like earth moving equipment). Thu si know more than much more educated people about very narrow particular information that I just find fascinating. This really took my career very far before it was stopped by becoming disabled.

Many fields of study have a really hard time admitting that an issue is more complicated that they can explain, regardless of whether to children or adults. Far more humility is needed in how we articulate how confident we are in results. When I started pursuing my degree in science I was blown away at how huge of a chunk of the information we take as 'fact' is not actually evidence based. Here is a great example, did you know that the speed of light has NEVER been measured to have the exact same value in two different tests, yet we call it a constant? The value we attach to the 'constant' is actually an average of several very similar, but slightly different measurements. Consider the second clip of this video where the woman talks about atoms. Our current model suggests a cloud, yet that's never been observed, so we speculate that our observational tools must be making it go away. In other words, rather than accepting that theyre wrong, they moved the goalposts and said theyre still right, it's just not provable with modern machines. While discussing how every previous model of atoms turned out to be false (even though the technology we made using them worked perfectly fine) the narrator still claims over and over that this time we've definitely found the real one, a claim I'm sure was made by proponents of every single outdated, unverifiable model.

We didn't even get to cellular biology until highschool, and even then anything more was part of a dedicated biology class. We also never had the quote of "mitochondrial is the powerhouse of the cell", we were taught it was involved in converting sugar to ATP among other things I can't remember. We even had to fight to have calculus in grade 12. Shop class was mostly spent in line waiting for use of a given tool, which took at least 5 minutes each person to reset to what they needed then time to use it, so often there would only be one step done in a project per class. All told, school was less useful than it could have been.

School in the 90s taught me that different parts of your tongue had receptors for specific types of taste (sweet, sour, etc.). It was only when I was a second year psychology student that I learned that this is not at all true; each part of the tongue has the potential to experience any or all different tastes. There are also taste receptors in your mouth and throat that were completely omitted in older models

The problem with "5 senses" is that it depends how you define distinctive senses. A lot of people would lump those extra 3 into "touch", maybe because they're all related to how we physically interact with the world - for example you sense temperature when you 'touch' something warm or cold, even if it's the air. I've seen articles that argue we have dozens of senses. What about thirst, hunger, fatigue, the ability to sense the passage of time, pressure (the ability to pick up an egg without breaking it goes beyond the simple sense that you're touching it), the need to pee, the need the breathe (i.e. carbon dioxide levels in the blood), etc.? And then there are senses that follow on from others. For example, you can get a sense of the physical space you're in by listening to how sounds in the environment reverberate. Blind people tend to be very tuned in to this - essentially it's like echolocation. Technically, it's just hearing, but you are 'sensing' a lot more than sound.
