Hey /sci, what's the best book on astronomy that you could recommend to me? Nothing too advanced, I just want to know more about our solar system, possibly even Milky way as well.

All I know about astrology is the names of the planets in our solar system and their rotations and orbits and nothing else. All submissions are thanked in advance.

because it's caused by an "overmasculanization" in-utero development. High placental testosterone levels cause it.

Dragon has 100 heads. A knight can cut 15, 17, 20 or 5 new heads, but in doing so, the dragon grows 24, 2, 14 and 17 new heads respectively. Can the gentleman leave the dragon without heads?

If there are 16 heads left is the knight fucked and unable to do anything?

>>9093619

You literally cut 17 heads each time, giving you a net average loss of 15 heads. When 10 heads remain, you cut them all (that counts as 17), and the dragon can't grow shit back according to its rules.

I just read a youtube comment that gave me stage twenty cancer: "The law of conservation of energy cannot be used as an argument against the existence of perpetual motion machines."
>nigga what
What makes people believe in things like perpetual motion machines and flat earth to the point where their head is so far up their own ass that they somehow come up with endless counters to any logic?

He is right.

conservation of energy is not the law that precludes perpetual motion machines.

Its only when you bring the 2nd law into play that perpetual motion becomes impossible

/sci/, what's the point of protecting local ecosystems from invasive species?

Why don't we just let, say, Australia be overrun by whatever? Sure all of the native species would be driven to extinction (frankly, improving Australia). And sure, there will be periods of suck as certain invaders have population explosions. But it would stabilize over time, right? Explosion of foreign rabbits is followed by an explosion of foreign foxes is followed by equilibrium. Right?

If we stopped trying to preserve exotic or endangered species and just let natural selection do its thing, could we, ultimately, "standardize" the global ecosystem?

>>9092622
it's really only a problem when it's a problem, like when a local crop or resource is threatened. But by their definition, invasive species do threaten other species, so they overall reduce local diversity, which is in general a net negative (high localized ecological diversity is the best indicator of a healthy environmental area, as ecosystems go).
>>
>>9092622
you are fucking retarded.

Humans are part of the ecosystem too. What happens when the species driven to extinction is cows or corn?

I want to try this DNA testing kit to see my ancestry lineage but I feel uneasy giving my DNA out. I guess I'm concerned of having some mad scientists centuries from now re-create my body and and consciousness with my DNA and my mind is stuck in an infinite long science experiment.

Do you guys think that's possible with just DNA? Or am I overreacting?

Imagine if you will, if a group of almighty aliens gave humanity near limitless power, sci-fi replicators, and intelligent robots that could do any sort of menial or taxing job.

The experiment is to see what humanity would do in truly post scarcity, high automated life.

How would this work in the small scale such as a town? Or a whole planet? It stands to reason people like researchers, artists, and politicians would still exist but what would the layman do?

People actually get paid taxpayer money to write this gibberish? How does that make any economic sense?

>How does that make any economic sense?

You must understand academia economics. The first thing that you need to accept is that someone produces no value to a business then that person gets fired. So the question is, what value do mathematicians produce? The first one is obvious: teaching. Every year many students of mathematics sign up to be taught mathematics and if you do not teach them then they will go away to another place, losing the university money. And usually, math professors teach all over the place, not only in the math department but to scientists, economists, etc.

That said, there is other way in which mathematicians are able to produce value: research. If your university does not produce research then people will hardly consider you a university and you will quickly dip in the rankings and every time a prodigy student to be looks up your university's credentials they will see that your university is shit and therefore their time would be better spent somewhere else. So universities need researchers to keep reputation and to attract the good types of student. Good students pick schools mostly based on who they will be able to do research under. But that is just baseline produce any research type of value. There is another incentive that ties this up: the value of good research. If one of your researchers becomes famous then your university immediately gets a spot in the map. People will want to go to the conferences of your school, and other universities will want to invite your mathematicians to their conferences. This will in turn inspire the new generation of prodigies to get into your university for the possibility of researching under your famous researchers.

And that is the economic value of research mathematics. You are welcome.
