I can still vividly remember being twelve years old. I remember sitting in middle school science class. The teacher liked to show old real-to-real science films left over from the 60’s and 70’s. As we sat and watched these movies the teacher would rush over to the projector and stop the film. She had to explain that the information just presented in the film was outdated and now known to be untrue. She explained that our scientific knowledge is continually developing and expanding and that many things that were recently thought to be truth have turned out to be only partial truths, or in some cases turn out to be blatantly incorrect.
As my twelve year old self sat there listening to the teacher explain this I looked down at the science text book that was sitting on the table in front of me. Unlike the old reel-to-reel film, the textbook was a recent scientific publication. It struck me as odd that the writers of this text book present their information as fact rather than as theory. I wondered to myself how much of the information being presented in this text book will, in the future, be known to be inaccurate or even blatantly wrong.
