Portal:Science/Intro

Science is a verifiable body of data established through a series of experimental investigations, empirical knowledge of phenomena that can be observed or repeated, and a set of techniques for investigating, through research, repeatable events using a systematic procedure known as the scientific method. Natural sciences such as physics, chemistry, biology, and astronomy study nature; social sciences such as economics, geography--concern themselves with both the physical & the cultural; politics, psychology, sociology, and anthropology study human beings and society.

The concept of reproducibility is the unsung workhorse of the scientific method: Galileo relied on this concept to develop his law of falling bodies. Without this concept, scientists would be unable to verify the claims of others. Without it, technological products would fail upon second use. Reproducibility is a requirement for a law of nature.

The laws of science are (as far as have been determined) consistent throughout the universe. However, because conditions may differ from one location in the universe to another, the results of experiments may differ as well. It has been proposed that there may be other universes in which the laws of science are different.
