People never thought the earth was flat.

Some human races are less evolved than others.

The Egyptians figured out the Earth was curved by comparing the length of shadows on the equinox. However I'm sure many people still believed the Earth to be flat.

If you could make more neurons, could you copy the connections over while the old neurons are slowly erased? Basically cut and paste?

You could argue it's still you, since you don't lose your stream of consciousness. It'll be like a comparison of you to a year ago, you are completely different but it's not different in a way that the whole teleportation thing works, more the difference of you to a year ago.

>You CAN regrow neurons, although the extent of the effect this has on learning and memory is debated.
...
you sure?
where did this myth come from, in that case?

>>1368602

Did you learn that from Cosmos like I did?

Some people think all races are equal and that men and women are equal.

Humans didn't evolve from monkeys. Monkeys and humans share a distant, extinct, common ancestor. Humans also didn't evolve from apes... humans ARE apes.

mee too

The idea that by observing a particle--for example, by bouncing a photon, off a particle and recording the photon's behavior to determine the behavior of the particle--you inevitably change the particle's position or momentum IS NOT THE HEISENBERG UNCERTAINTY PRINCIPLE

It's the Observer Effect

The great wall of China can't be seen with the naked eye from orbit; its narrower than a highway.

The below sea level land Holland reclaimed with dykes, there's something visible from space.

Does that mean we can successfully have offspring?

>>1368636
what is the heisenberg uncertainty principle?

I mean it's still the statement that you can't know both a particle's momentum and position at the same time, right?

Chlamydia is a genus, not a species.

this.
If this truth were popularized, there would be much less bullshit around here...
I'm afraid that going in depth by saying anything else; I'll ruin a legitimate science thread.
So I'll stop now.

Yes, adults create stem cells. Half of them die from the beginning, the one third of the remaining make neurons. That was what I was taught in school.

>>1368576

Are you referring to very very recent "games"/training created by neuroscientists to increase cognition in the elderly?

ah yeah

tired?

The tongue has many tastes, not limited to four basic ones corresponding to areas of the tongue...

I remember getting in trouble for noting that when I ate a lolipop, I felt the same flavor on all places on my tongue...
Fuck you Brewster Elementary. I hope each one of you teachers gets cancer.

I don't remember, but probably. That series is fucking awesome.

You were smelling that, not tasting it.

Limited testing.
Not the guy who posted it, but when I first heard about this, it was from a muscle mag of my older brother's (lolgaypornforclosetedhomos), and said that the new neurons were only formed during exercise.
>>1368824
Fuck yeah. I know what you mean, man. Fucking teachers.

Water going down a drain in the southern hemisphere doesn't rotate in the opposite direction of water going down a drain in the northern hemisphere.

>>1369037

so how did that myth get started?

>>1369161
Simpsons did it.
Had a roommate once who insisted it was a fact, his expertise being derived from the fact that he played WoW with a fat Australian chick. I never had the heart to tell him it was a fat Australian guy, who'd likely never been harder than when he brought up the subject of BM.

Common scientific misconceptions?

-The universe is infinite

Mixing ammonia and bleach does not produce chlorine gas.

It actually produces liquid chloramine, which is only overly hazardous to breathing in fairly confined spaces.

It is a commonly believed fallacy that evolution is always "improvement" or "refinement."

>>1369649

look at this faggot

"Volts jolt, amps kill"

In reality, it takes a combination of sufficiently high voltage and sufficiently high current at the right frequency, all together, to kill. A very low voltage source capable of high currents will not deliver dangerous shocks, same with a high voltage source with very low current.

Generally a source has to be at least 50V and capable of putting out at least 20mA for a sustained period (at least a few seconds) to be considered dangerous, in most cases there is *fairly little* risk of *serious* injury until nearly double these values.

Frequency also plays a huge role in how a shock effects your muscles, once you get past 10khz the only danger is burning of tissue.

The skin effect applied to humans is basically a myth throughout most of the low microwave range, you can easily get deep burns from a high power tesla coil or radio transmitter.

>Humans didn't evolve from monkeys

actually that's not true.

Humans are apes.
And all apes and modern monkeys evolved from a species categorised as a monkey.

Humans are monkeys, just like humans are mammals. We never become anything other than mammals, and no ape will ever become a non-monkey.

>>1369723

Humans are not monkeys.

They are apes.

Learn the difference between an ape and a monkey.

>>1369696
I thought it had to do with the natural resistance of our skin.

If you insist, just know that repeating it doesn't make it so. I'm done talking to you

Apes and monkeys are both simians. apes don't fall under the monkey catagory
