How much time will it take to fully terraform Mars with nuclear weapons?
Is it worth it?

It can't be done with nukes, regardless of the amount you use. You need asteroids and comets to smack into it after slingshotting around the sun or whatever trajectory would be best.
How can I statistically compare these lines?
I've been struggling with this for weeks, but I know its a basic question and just don't know the correct terms to google.
I basically , I have several ‘lines’ on a line chart, each representing what is known as a ‘spectral profile’ for different plant species.
What I am hoping to output, is some sort of quantitative value, that can outline how ‘unique’ these profiles are from each other.
I've been told PCA but that isn't making any fucking sense.
Unique in what way? Shape or the dependent variable?
>>8855125
Dependent - I'm trying to numerically explain that the grey one is much more different than the yellow, etc...
>>8855111
It looks like a hat.
Did you know this?
How do you compare hats?
I've extended my PhD already by 3 months to write up. I am overwhelmed by writing and report writing in general. I feel like I'm average-above average intelligence and a good researcher, but I can't put my thoughts on paper. moreover, I feel like I don't have an extensive vocabulary, and spend far too long looking for thesaurus alternative words. anyone with experience getting a PhD done during the final stages?
>>8855027
What's your PhD in? STEM writing is meant to be terse. Don't use "alternative" words for no reason. Terminology should be consistent
>>8855027
thank you anon this makes me so happy
>>8855523
Yeah, you should know all your words because they are directly relevant to what you are working with.

>The idea that race itself is a purely biological immutable quality is also understood today as being simply untrue. Instead race is thought as a socially constructed category of people, who share biological traits that society has deemed important
>Human beings vary a lot in how we look, our skin color, facial features, body shapes, hair textures, but those visual markers only become a race when members of society decide that specific markers constitute a specific racial group.
What did scientists mean by this?
>Human beings vary a lot in how we look, our skin color, facial features, body shapes, hair textures, but those visual markers only become a race when members of society decide that specific markers constitute a specific racial group.
or when you need a bone marrow transplant and will reject the transplant if you get it from someone of the other race

Beforehand, you may freely flip a coin as many times as you want.
Will flipping a coin until it lands on heads 5 times in a row increase your chance of landing on tails in the real coin toss against me?
>>8854696
No. Each flip is independent of the last.
Babby-level question for babbies who don't understand the independence of events.
If you have any understanding of epistemology, you'll know that absolute knowledge is impossible.
Here's why:
1.Either all of physics are infinitely regressive, particles within particles within particles etc, hence not anchored in any solid way
2.Either it's somehow circular, thus not anchored in any solid way
3.Or all of knowledge hangs on some random/weird type of phenomena
There's nothing else, all of science, no matter how rigorous or how far into the future, is just an approximation.

So, a science to tell us that science will fail?
Your conclusion is correct but your reasons are baffling and implausible.
Yes but the more vast and detailed our scientific knowledge, the more godlike our technology will become
"Why do I have to learn Algebra if I never use this in real life?"
What do you say?
>>8854216
It helps you improve your problem solving skills, which is useful throughout your life.
>>8854222
Then why don't they just teach logic instead of algebra?

If you love science, why didn't you go to law school and become a politician?
Nuclear energy won't be getting off of the ground anytime soon.
Fossil Fuel cronies are lobbying the fuck out of the government and its working.
Green? What is that.
Evolution, STEM cell research/cloning and similar activity with genes is being attacked by religious folks
Most importantly, your precious precious funding is in constant danger in top public institutions such as Georgia Tech etc
If you claim to love science, why won't you protect her and go to law school instead anon?
>>8853621
>you FUCKING love science
>but you won't even talk about genetic differences in race
>while on the topic of gov't funding can't even imagine corruption of the scientific method
>don't even realize green energy is a major league sink hole of tax payer money
>AND you have the GALL to consider morals when extracting info from the spines of dead babies and the possibility of cloning another human being
My science is saging
>>8853621
You can promote science / protect cute scientists without getting involved in politics.

Sigmund Freud postulated that men compensate using a strategy whereby one covers up, consciously or unconsciously, weaknesses, frustrations, desires or feelings of inadequacy or incompetence in one life area through the gratification or (drive towards) excellence in another area.

This rocket was designed to lift the same payload to LEO as Musk's rocket (550 tons)

It flopped. Therefore Musk's rocket will flop too.

I'm programming something that needs super efficient collision detection, and figured that rather than checking collision per-frame, I could use the velocity and acceleration of objects to create parametric functions that show when and if those objects collide.
However, it only works for collisions of spheres, because I'm finding when the distance between the spheres is r1+r2..
I hear there's similar stuff that works for non-spheres, can someone educate me on this?
>anime picture
Haha, no.
Sage goes on both fields guys, remember.
>>8852662
Collision detection is inherently expensive, and there will always be a trade off between accuracy and speed.
What's the specific application you're developing it for?

If we invent the singularity will it be awesome when the machine assists you when you research stuff? Granted that the singularity does result in a superintelligence it could solve the Millennium Prize Problems in hours. Imagine the computer showing the way and giving you tips while you research them yourself. It would be like a chess computer.
How are gas powered items like weed eaters tested before sent to the retailer? Do they actually put fuel in them ? If so what happens to it after?

How to discover a graviton?
>>8848139
a graviton is not a real particle in reality. a single graviton would have the form of the entire universe one oscillation back in space-time. gravity is a multi-tool of energy balance, but it does not interact through particles. it is the connection between them. the unified universe is a graviton.

I had read that it was a hypothetical particle, thanks for the clarification
