The basis of modern science is observation and hypothesis.  It involves constructing the best theory to explain an occurrence based on the evidence at the time.

Economist [[Milton Friedman]] said, "In all of science, progress comes through people proposing hypotheses which are subject to test and rejected and replaced by better hypotheses." [http://www.pbs.org/wgbh/commandingheights/shared/minitext/int_miltonfriedman.html#10]

The [[scientific method]] consists of two stages, theory formation and theory testing. In the early 20th Century the scientific method was commonly understood to follow the [[inductive reasoning|inductive]] procedure, whereby general statements are derived from a collection of singular observations. It was thought that through this method theories were constructed; a collection of observations led to the formation of a general theory to explain them. Secondly, at the testing stage, it was considered that a hypothesis could be verified through a collection of singular observations.
