Science isn't something arcane, intended only for the few. Everyone of us - whether a poet, janitor, or nuclear physicist - has to be able to think scientifically, and to understand some science, to get through with our lives. Every day we face decisions that hinge on science, such as whether to smoke, what to eat, with whom to have sex, and what protection to use (if any). Even for decisions that don't depend on specific scientific facts, science remains the proven set of best methods for acquiring accurate information about the world.
