It is a way of thinking. Science invites us to let the facts in even when they don't conform to our preconceptions. It counsels us to carry alternative hypotheses in our heads and see which ones best match the facts. It urges us to maintain a fine balance between a sincere openness to new ideas, however heretical, and the most rigorous skeptical scrutiny of everything. No one has defined science more eloquently than Thomas C. Chamberlin, one of the greatest geologists who ever lived.
Science is a never-ending search for truth.
We may not always reach our goal, but the search is satisfying nevertheless. Why science is important One way to view science is as an approach to thinking that minimizes the chance of being misled by an observation. In other words, it is a set of rules to avoid being fooled. The scientific method teaches us to make many observations and examine them as a group. Bad science develops rules based on single observations.
