Scientific laws or laws of science are statements, based on repeated experiments or observations, that describe or predict a range of natural phenomena. [1] The term law has diverse usage in many cases (approximate, accurate, broad, or narrow) across all fields of natural science (physics, chemistry, astronomy, geoscience, biology).
Before Newton’s law of gravity, there were many theories explaining gravity. Philoshophers made observations about things falling down − and developed theories why they do – as early as Aristotle who thought that rocks fall to the ground because seeking the ground was an essential part of their nature.

The constants listed here are known values of physical constants expressed in SI units; that is, physical quantities that are generally believed to be universal in nature and thus are independent of the unit system in which they are measured. Many of these are redundant, in the sense that they obey a known relationship with other physical ...
Natural law [1] (Latin: ius naturale, lex naturalis) is a system of law based on a close observation of natural order and human nature, from which values, thought by natural law's proponents to be intrinsic to human nature, can be deduced and applied independently of positive law (the express enacted laws of a state or society). [2]
Conservation laws are considered to be fundamental laws of nature, with broad application in physics, as well as in other fields such as chemistry, biology, geology, and engineering. Most conservation laws are exact, or absolute, in the sense that they apply to all possible processes.
For example, physical laws such as the law of gravity or scientific laws attempt to describe the fundamental nature of the universe itself. Laws of mathematics and logic describe the nature of rational thought and inference (Kant's transcendental idealism, and differently G. Spencer-Brown's work Laws of Form, was precisely a determination of the a priori laws governing human thought before any ...
While the numbering of the laws is universal today, various textbooks throughout the 20th century have numbered the laws differently. In some fields, the second law was considered to deal with the efficiency of heat engines only, whereas what was called the third law dealt with entropy increases.
Nature is an inherent character or constitution, [1] particularly of the ecosphere or the universe as a whole. In this general sense nature refers to the laws, elements and phenomena of the physical world, including life.
