We were taught blood was blue in school, not just once, in at least two grades. Not in the book mind you, but from the teachers' mouths.
The 7th grade science book did teach us gamma rays move faster than the speed of light, which is bullshit.
The worst misinformation we got was that after erections (which functionally are made via blood flow) boys pee out the blood. Like Jesus fuck lady, what is wrong with your husband.
PSA: Go to the doctor if you're pissing blood.
That's definitely not about her husband, it's about scare tactics. The reason behind using scare tactics can be many, like religion, suppressed sexuality, what she was taught or even just not wanting to deal with her students doing stuff. It's absolutely not ok to say that no matter the reason though.
That's an odd one, since you'd think peeing or not peeing blood would be very easy to verify.
Wat
We still have pictures like this in books! It makes it hard to break the cycle.
Gamma rays do travel faster than light through some media, but obviously not faster than c, the speed of light in a vacuum.
Gamma rays are photons like light no? Is the speed in a medium related to its energy/frequency? Or am I misunderstanding something
Well yeah, the media was that one kid's 7th grade science book
by my grade 7, i had already learned all about dalkon shield and iuds, silicone breast implants and their risks, rely tampons and toxic shock syndrome, roe v wade, aids and homosexuality......
that was just the sex ed units from the regular nightly news.
OK
Came here to say the same thing, for years I was believing my blood was blue before it hit oxygen....
I was going to add the "hitting oxygen" is an important part of the blue blood myth back then.
Which is really funny since your blood is already oxeygenated
Holy shit.
As someone who does not possess the knowledge, is blood white? The deoxygenated channels?
Plasma separated from red blood cells is sorta yellowish beige. At least in IV bags.
It's actually green

That one guy in Carbon Creek is an outlier and should not be counted.
Blood separates into white, yeah. That's basically my understanding of (a type of) pus formation.
