Science is not truth, but rather it is a way of thought. It is a process by which experimentation is used to answer questions. For the members of the MacDoth Clan experimentation was real life.
Scientists are generally curious about their surroundings.
This curiosity leads them to ask questions about the world around them. As scientists formulate questions, they naturally try to answer those questions. Those attempts to answer questions lead to hypotheses, or some would say guesses, regarding the question's answer. Of all the steps in the scientific method, the one that truly separates science from other disciplines is the process of experimentation. In order to prove, or disprove, a hypothesis, a scientist will design an experiment to test the theory.
