Where can you get specifics?

[javaslinger]

Is there somewhere where it tells you how much population affects reserach, affects mining, affects intellegence, prooduction ect? What about how much happiness effects these things? What kind of bonuses you get for building/researching/mining on your homeworld vs a colony? Or how much plantet conditions affect these things?

Basically where can I get the details?

Thanks
