Deep Space 9 and gaineg experience

Well, we had back story available to us. By the time we got to Deep Space 9 we were in the fifth season of Next Generation - we'd done close to 150 episodes of Next Generation, at that point, and we were getting pretty well grounded. We've all gotten a good, scientific education over the years, and we continued to have people like Andre and others who were there to help us.

When Voyager came around, a few years later, and even now, when the new series is about to begin, we continue to build our background of scientific knowledge and also to get a better idea of where to turn when we need some help.
