This seems fucking cool. But please, no space communism.

What I find strange is how it looks like it's melted in some places.

it looks like an artifact/fossil of some sort, if youre sure its a stone hit it with a hammer and take a picture of that.

>>8628683

/pol/ how do you explain this picture that NASA released?

I am legitimately curious. Do you see this as a problem? Do you think the change is reversible?

>>8628683
rip arctic it could change but its very unlikely even if you believe climate change is happening for different reasons

what i wanna know is why most scientists and people think that the water levels would rise?
does earth not follow displacement laws?

Here's a rundown of humanity's options.

long arms tend to be an advantage in pulling movements like deadlifts, but a liability in pushing movements like bench press

>>8644899
>are people with long arms stronger?
Generally yes

>>8644899
no, if you thought about it for even a second you would realize that no leverage is given when the applied torque is at the same point as the fulcrum

That is until power structures came to be.
If you are the ugly son of a rich man then odds are some slut will marry you.

For the past thousands of years even being middle class and ugly allowed you to marry and fuck.

And now that there are ugly populations, everyone can fucking mate. So that shit stopped being true a long time ago.

From an evolutionary perspective it was quite recent.

Yeah yeah, whatever. You are going to die in 50 years.

It's too verbose. You should try python desu

Go do your homework somewhere else, OP.

>>8644341
I made it verbose so you could solve the problem. It's example code.

Is there actual research that proves this?

I minimize my use of "scented" products. Only exception is deodorant and cologne. For keeping my room smelling fresh I bought an oil diffuser which works wonders

As a toxicologist, you have no fucking idea how fucked up shit is. Synthetic polymers are the devil and will destroy the world from how absolutely terrible they are for the environment around us, let alone us, but they're extremely economical materials so absolutely nobody would ever go against it. fucking idiots.

>>8644263
Here is a small list of what makes up those scents you get in products like in the OP...

>Butylated hydroxytoluene
>Acetaldehyde
>Benzaldehyde
>Butylphenyl methylpropional
>Ethyl acetate
>Limonene
>Methyl pyrrolidone
>Propylene Glycol

...all highly toxic to some system in your body. Now obviously unless you are huffing this stuff chronically, it won't kill you, and the greatest concern is the effects on prenatal humans, but you're not doing your body any favors by being exposed to them. Hell, you have Bisphenol A and Bisphenol S in all of your water bottles too, which disrupts your endocrine systems and mimics estradiol, AKA estrogen. You're basically drinking estrogen every time you drink anything from a typical plastic container, all because of synthetic polymers. These synthetic compounds are also toxic to our environment. I could go on and on about the effects of just these two singular compounds and not touch anything in that list above.

non biofag here

wouldnt continually making more antibiotics just lead you to superresistant bacteria that have a higher chance of taking us out? is there not some middle ground humanity needs to stay within?

No, we either have something to prevent children and people from dying from superficial cuts, elective surgery, malaria, etc- or we don't.

>>8644209
I agree, social studies, art and such should always exist only by the grace of useful science. What scraps can be spared from real work can go into these trivial pursuits.

unless you already naturally sleep that way, then no.. the amount of sleep we need is almost entirely genetic

>>8644120
>is it possible to function normally?
Yes, I rarely get more than 4hrs a night unless I'm sick.
You don't need to take it in shifts, I just sleep from around 12-4 or 1-5

>Can the average 4channer do the same?
Sure why not.

6 hours on the average day for me but 5 hours when I don't feel like going to bed on time and 4 when I really don't want to go to bed.

It's probably a 70 20 10 split across all three.

I could probably do with four hours per day but I'd be hella tired by midnight.

It's only a one level simulation though.

Not op but you left out the if.

everyone does this, which is why the textbooks do. Electrons have negative charge so a flow of positive charge is the negative of the flow of negative charge.

I'm not an electrical engineer, but my assumption would be that people wanted to work with a quote-on-quote "positive" property and it has simply been the convention ever since

WARNING: Having the following information is dangerous.

This is a conspiracy. The powers to be do not want technology to develop beyond a certain point. Misleading nomenclature and unnecessarily complicated process descriptions are a way to obfuscate knowledge and understanding. The economic realities make it impossible to work if you do not operate inside this system of deception. A good portion of scientific theories accepted as truth break down if you formalize them in a clutter free notation. And yes, this was done deliberately and knowingly.

>>8643721
The textbook seems to imply that the positive charges are physically moving. Also current can flow in an open circuit under the right conditions.

Knowledge is created by making lots of mistakes and taking small steps in the right direction. Alchemists were on the right track though, but became outdated by newer and better insights.
