Is there a scientifically perfect way to play Age of Empires 2?
Checkers is a solved game.
Connect 4 is a solved game.
Chess is soon to be solved.

How long until a videogame like Age of Empires 2 is solved? Is it possible to play a "perfect" game of it?

If you have a defined ideal, with no regard for internal ambivalence, then it is always possible to do something perfectly.

Answer from an actual game programmer. Look at it this way AoE2 runs at 30 frames per second. So it's actually a turn based game with a finite grid. So you could solve it for each turn/frame in the same way you would solve chess. You could give all the variables and relation between all variables a cost. Then recursively you could iterate between all possible outcomes of the turn. Then choose the best outcome. For that frame and calculate this for all upcoming frames. It would be computationally very heavy but not impossible.

Can you id this insect?

Pic unrelated

So basically I see only small dots of red in the room flying as if it were an insect, but it's not alight all the time, also they illuminate a bit when close. but it is a brief flash, not continuous.

They are poisonous, I slept a lot when bitten and have been dizzy for quite a while, though I am better now.

Not sure what else can I say, some bits of my face were kinda paralyzed, hard to move more precisely, a part of my upper lip for instance.

Can someone explain in an intuitive way how newtons laws tell you that a particles trajectory is determined for all future time? I.e. that if you specify a position at t=0, you know where that particles going forever?
>>
$\frac{1}{m} \sum \limits_i \int F_i\ dt^2 = x(t)$
>>
Second law: F = ma.

The first law is a special case where F = 0, meaning that a = 0. The third law doesn't matter if you are thinking about a single particle.

The second law says that if you know the force on a particle at all times, then you know the acceleration at all times. If you know the acceleration, then you know how much the velocity is changing. If you know the velocity, then you know how much the position is changing.

It's just a cascade of information.

That's it, really. So you need to know the original position and velocity,...

never heard of this one but I'm a combo guy.

Concrete Math is reeeeeeeeeally good. Pretty much the classic discrete math book for mathematicians.

Generatingfunctionology is a cool next book to read. If you're into graph theory get anything by Bollobas.

If you want to study some "offbeat" combinatorics, check out Combinatorial Designs by Stinson. Best introduction to that field that I've seen.

What are the neural substrates of racism?
>>
>>7643640
Most human faculties that allow for higher reasoning afford the presence of racism. It's a very natural thing.
>>
>>7643640
Many animals have a way of identifying family members, to avoid breeding with them; and a way of identifying things which are too different and thus that they shouldn't try to breed with (like other species). Racism is just the latter such mechanism being triggered.

Are there any devices available that prevent AC from feeding back into a line after a device is turned on / off, etc?

I know very little about electricity. My mother is concerned that ripple in the otherwise (relatively) smooth 60 hz sine wave is interfering with her sleep and general health. I don't really have much of an opinion, I'd imagine it's probably emitting radio waves in a general band that's fairly small. Not certain what a given magnetic field flux and field strength would do, and my own health is so trashed to begin with, I don't...

What is /sci/'s opinion on qualitative research?

I used to think that it was incredibly weak and the reason why people (unfairly) thought of social science as being soft and non-scientific. However I'm currently doing an MSc at a university where they have a strong tradition of qualitative research and they've pushed it pretty hard, and I can now see that it has some value and can answer some questions that quantitative research can't. If I do a PhD, I might look to do it using qualitative methods because it seems easier and more interesting. What do you think?

Might even be better than sociologists misunderstanding statistics and using it incorrectly

Social sciences aren't sciences though.

Are you really saying things like history, law, and economics are sciences?

The first generation of brain uploads would be designed by meat brains, they would try to replicate meat stuff like emotions and individuality, but the computer brains would quickly realize there's no point to these limitations and would redesign themselves to be a single hivemind processing unit.
