Quantum entanglement can transfer information in a way that isn't bound by the speed of light.

    in a way that isn't bound by the speed of light

    But also in a way that is utterly useless for faster-than-light communication.

    Isn't quantum mechanics fun? :)

    didnt i read that birds are a direct lineage offspring of dinosaurs? i think that one is actually not made up. hm, wait. does it count as extinct if you produce offspring that survive but they arent your species anymore? or is that just dead.

    Yeah actual answer is that only the non-avian dinosaurs died out (along with many other creatures, including some that folks mistake for dinos like pterodactyls and plesiosaurs).

    But birds are obviously still around today and they are true dinosaurs according to most biologists/zoologists/geneticists/etc.

    'Species' is an astonishingly hard thing to define though so I'm not gonna touch that one.

    Perovskite photovoltaic cells are named after Andrej Perovski, who invented them in 1965 in St. Petersburg. The technology was shelved for decades due to poor longevity and high costs at the time, and Perovski never lived to see it picked up again and developed like it is now.

    All humans have 46 chromosomes and as the most complex organisms that's the highest number among all species.

    I think due to genetic mutation that some humans have 45 and some have 47, but by and far the largest majority of humans have 46 chromosomes.

    When I was a teen, my sister came home one night hammered. She was worried that she had work the next morning and was going to be hungover.

    I told her I saw something on the discovery channel (early 00s) that businessmen do to reset their internal clocks when they travel! They put small flashlights in their socks, pointing them at the back of their knees. Yeah! Apparently if you expose the back of your knees to light while you sleep it totally resets your internal clock!.

    Not only did she wedge two flashlights into the couch cushions and sleep on the couch, it placebo worked so well she went to work and told everyone about her new life hack.

    you can tell species apart really easily! if they mate and produce offspring theyre in a species. its that simple!

    The female lesser prairie chicken, the only remaining wild chicken, will peck holes in their own fertilized eggs in times of scarcity making it one of the only other species on Earth that perform intentional abortions.

    There is a small chance that this is actually a true fact, but I've never been able to find any source that backs it up. I haven't looked hard, but I have looked, and my google-fu is usually pretty good

    I remember hearing once that "blue raspberry" flavor exists because when food scientists were trying to come up with a formula for artificial raspberry flavoring they just couldn't get it quite right, they got pretty close, but not quite close enough for people to buy that it tastes like raspberries. But some marketing guru decided it was good enough and they'd just color it blue and people would accept it "of course it doesn't taste like regular raspberries, this is blue raspberry, it's different, it's supposed to taste like that"

    And yes, blue raspberries kind of actually exist. They probably used that as justification banking on the fact that most people don't actually know what they taste like.

    There's also some stuff about a certain red dye being banned at one point, and marketing also wanting to differentiate raspberry because people already associated red with flavors like cherry, strawberry, watermelon, etc. and those are probably true as well, but I don't think those reasons are incompatible with this explanation.

    I think the marketing history of using blue to distinguish raspberry from other red fruit flavors (cherry, strawberry, etc) is true. Sources also say candy and drink companies wanted to get away from unsafe Red 2 dye like you mention.

    Fruit flavors can be complex combinations of esters and other compounds. But the core taste/scent of raspberry seems pretty straightforward though, mostly just a ketone and ethyl formate.

    Here’s a few for you:

    Electricity is electrons flowing through a conductor.

    In an atom, electrons orbit around a collection of protons and optionally neutrons.

    In an atom, electrons exist as energy “shells” at varying layers around the proton/neutron core.

    Bonus points to the people who can explain why these are all false and what the reality (as we currently understand it) is. Transformers are a clue for the first one :)

    For the electricity one, I'm guessing you're thinking of AC, where electrons move back and forth instead of continuously. But DC current does actually involve electrons moving continuously in one direction. Even a DC transformer is theoretically a thing, though I've never known one to be used as a transformer (usually a similar thing is used for electrical isolation, but it's a similar idea under the hood).

    Or you're making the distinction that electrons don't move through a conductor, they move along (the outside) of a conductor (mostly).
