Mod Creation Help

[Ilikepie]

Hi, I'm completely new to the world of modding, and i'm just after a simple change for a scenario i want to make.

Basically, slightly similar to decreasing the game speed, i want all units and buildings to build at the normal rate, but i want to slow down the science rate, so longer is spent in each era. I am wanting the science rate tripled, so say in the standard game speed, technology X was to take 10 turns, i want it to take 30, And i want this doing for every technology.

I have no clues on modding, so could anyone help me out with this?
Also, how would i load this onto a map i have created?

Thanks veyr much to anyone that helps!
