[Fullmetal Alchemist] So aside from military/fighting - what is Alchemy used for?

Most of the Alchemists we see in the series are military men and women - Mustang creates fire, Armstrong shoots rocks, Ed and Al smack people with pillars of earth - but what are the other uses of Alchemy? How do they work?

I think we saw someone (might of been Ed actually) use Alchemy to fix a radio, how does that work? Does that mean everything is assembled with Alchemy or are there still electricians/factories around?

There's plenty of occupations still around, because alchemy hasn't been shown to be as precise as human craftsmanship, which is why Ed still goes to Winry to get his arm fixed as opposed to just trying to use alchemy. To justify the radio part, they still had enough broad pieces to just reassemble it, so that's all Alphonse did.

Alchemy has a lot of uses outside of fighting, like Shou Tucker, the Life Alchemist. And just like Zhou Tucker, the state alchemists have to do some sort of thesis of their discoveries in order to renew their State Alchemist status, which was why Tucker was so desperate to find a finding for his research.
