LAW: Generally accepted, verified, fundamental principle of nature. Laws have been tested and verified through the scientific method. As a house is constructed from concrete, lumber, and nails, a theory is constructed from laws. To be a fundamental law of nature, a principle must capture a cause-and-effect relationship about the workings of the world.
