This topic might have a better name.

Is it Parsec, Parsek, or Pardek?

Talk about it here.

Professor Pardek (or Parsek or Parsec) was the genius behind the flight of the attempt of the Solaros 10 to exceed than the speed of light. It wasn’t a total success as Parsec got caught in the blast of the solar stacks and, in an energy transfer, was mutated into a kind of “neoform reptilioplas”. The Eleventh Doctor's timely intervention saw the effects reversed, the ship stabilised and Parsec and the pilot Sorben both saved. (DWA: Faster Than Light)
