Science is both a process of gaining knowledge, and the organized body of knowledge gained by this process. The scientific process is the systematic acquisition of new knowledge about a system.

generally the scientific method, and the system is generally nature. Science is also the scientific knowledge that has been systematically acquired by this scientific process.

Some of the findings of science can be very counter-intuitive. Atomic theory, for example, implies that a granite boulder which appears as heavy, hard, solid, grey, etc. is actually a combination of subatomic particles with none of these properties, moving very rapidly in an area consisting mostly of empty space.

Many of humanity's preconceived notions about the workings of the universe have been challenged by new scientific discoveries.

The terms "hypothesis", "model", "theory", and "law" have a different use in science to colloquial speech. Scientists use the term model to mean a description of something, specifically one which can be used to make predictions which can be tested by experiment or observation.

A hypothesis is a contention that has not (yet) been well supported nor ruled out by experiment. A physical law or a law of nature is a scientific generalization based on empirical observations.
