CHAPTER 1 ABOUT SCIENCE 15 We seem to be at the dawn of a major change in human growth, for as little Evan suggests in the photo that precedes the beginning of this chapter, we may be like the hatching chicken who has exhausted the resources of its inner-egg environment and is about to break through to a whole new range of possibilities. Earth is our cradle and has served us well. But cradles, however comfortable, are outgrown one day. So with the inspiration that in many ways is similar to the inspiration of those who built the early cathedrals, synagogues, temples, and mosques, we aim for the cosmos. We live in an exciting time! SU MMARY OF TERMS Scientific method Principles and procedures for the system- atic pursuit of knowledge involving [he recognition and formulation of a problem, the collection of data through observation and experiment, and the formulation and testing of hypotheses. Hypothesis An educated guess; a reasonable explanation of an observation or experimental result that is not fully accepted as factual until tested over and ove!" again by experiment. Scientific attitude The scientific method inclined tOward inquiry, integrity, and humility. Fact A statement about the world that competent observers who have made a series of observations agree on. Law A general hypothesis or statement about the relationship of natural quantities that has been tested over and over again and has not been contradicted: Also known as a principle. Theory A synthesis of a large body of information that encompasses well-tested and verified hypotheses about certain aspects of the natural world. Pseudoscience Fake science that pretends to be real science. R EV l EW QUE S T I O'N S 1. BrieRy, what is science? 2. Throughout the ages, what has been the general reaction to new ideas about established "truths"? Scientific Measurements 3.
