Magic and science are essentially the same thing in Zemuria. Science is what allows mankind to utilise magic! You'll notice when playing the games that a lot of the characters who are tech-heads are also strong mages, and vice-versa. It's the same "language" so there's a lot of overlap.
Trails in the Sky actually has a little lecture right at the start of the game to explain things better than I can.
