What exactly is marginal cost and marginal revenue?

Would it be correct to say that marginal revenue is the market price of one single unit, and that marginal cost is the cost of producing one single unit (which changes as the level of output changes)?

What are some scientific hobbies which could make me feel fulfilled without having a social life?

How did life begin on Earth?

What are the chances of finding anything interesting after digging a 2 meters deep and 2 meters wide hole in the ground? What are the chances of any archeologically valuable items or interesting rocks, ores and minerals to be found?

How is infrared spectroscopy performed on astronomical bodies? Do we actually emit infrared radiation all the way to the distance astronomical bodies to see the abortion spectrum?

Are there any militant atheist books? In other words, books which explain how to convert other people to atheism.

Please suggest me some interesting scientific hobbies.

My essays always end up being short. How do I write long essays?

If a funding of about 300 billion dollars per year would be given, could we build a Moon base which could be mostly self-sustaining, with greenhouses and shit?

I set up a space colonization promotion website at www.space-colonization.com (it currently has no content) a few hours ago, and need help with formulating and writing content.

I'm also planning to create a cyber-community which would promote space colonization by informing the policymakers around the world of the benefits of space colonization.

How do I calculate the distance which a space probe travels if a constant thrust is applied to it, but the mass decreases all the time, because the fuel is used?

Any documentaries regarding space exploration and/or colonization?

Any documentaries/films with scenes of space colonization and/or men going to distant worlds?

If we start building lots of ships like this with the bombs for them, to launch about 30 of them every year, how soon will we run out of uranium?

I posted a thread about triforce spamming on /b/ to get the administration's attention:

PSYCHOLOGICAL SCIENCE advice:

Hey /sci/, I have a problem:
I like performing various activities with people if there's nothing better to do (ex: bicycle riding, exploring and stuff, but not partying and drinking, though), but I don't get much pleasure from talking about stuff people usually talk about - I'm always left out in conversations, because other people find what to talk about and when with other people very quickly, and relate to each other very easily. Everyone seems very energetic and willing to talk with each other in any occasion, but I simply stay on my own. I had this problem for my entire life, and because of it, I haven't had any friends for a long while. The last time I was able to have proper conversations with people was back to the primary school, when I had a friend who was interested in the topics I talked about (planets and their properties, minerals, coins and such - now I don't talk about it because I know people wouldn't be interested) It feels as if I'm absorbed in my own imaginary space most of the time, cutting off from the real world.

Am I bound to fail to get any normal job and be homeless for the rest of my life because of this? Are there any commonly available jobs for this kind of people? Science-related ones would be preferable.

I constantly think of stuff when I'm trying to fall asleep, which keeps me awake for hours. The stuff I'm thinking about is often schedule related, so I always get up and write it down on a paper, to then never use it later. Does anybody else have this problem? If so, how do you deal with it?

/sci/, I'm 21 right now, and want to get frozen as soon as I die. I'm going to make a tattoo on my arm telling to freeze me, and indicating the phone number and name of the company which does the freezing, so if the technologies would be found to unfreeze me, I would continue living.

I advise you to do the same.
