[Fullmetal Alchemist] Why do the alchemists that we see in the series all practice just one type of alchemy?

I'm sure it's in part due to them specializing in that type of alchemy -- a theory supported by the fact that state alchemists are required to present research in their chosen fields -- but is that all there is to it? If so, why don't more alchemists research and use the techniques used by, say, Mustang or Kimblee, considering how powerful they are? Is it all "just science," as Ed has said? Or does it ride off of Hohenheim's explanation that only a few people are able to draw upon the energy necessary for alchemy, and, as such, people are better attuned to different types?

**TL;DR:** Alchemy: "Just science" or innate characteristics?

Throughout the series, alchemy takes a lot of study. It might be "just science" but most alchemists spend considerable time studying.

State Alchemists are military. Just like the military has a standardized style of combat, the state alchemists learn a standardized method of fighting with alchemy.

And just like there are many different martial arts of varying effectiveness, some alchemists work with special styles or methods. Like the Armstrongs who apparently pass their techniques down the family line.

So yeah it's just science. Most of our scientists also get stuck doing routine work and research while a few rock stars stand out. So it is with state alchemists and their more talented peers.
