MORE ABOUT LAW

What is law?

A law is a rule made by an authority and that must be obeyed.

A law is commonly made by a government, which citizens must follow or face punishment. For example, in most places there are laws about not stealing. If you are caught stealing, you could be fined or put in jail, depending on the law broken and the punishment set up for that law.

Law can be used more broadly to refer to a set of laws, such as all of a nation’s laws. To say murder is against the law is to say that murder is not allowed in the geographic area being referred to, such as a state or country.

Law can also be used to describe the legal field, especially as a career, as in Zola had always dreamed of a career in law, so she studied hard in law school.

In the sciences, a law is an indisputable fact about the way the world and the forces in it work. Such laws explain what happens but do not describe why it happens.

Example: I believe it is against the law to set up security cameras without posting a sign on the door.

Where does law come from?

The first records of the term law come from before the 1000s. It is believed to come from the Old Norse lag, meaning “laying order” or “fixed tune.” A law is established to keep members of a community in order and fixed to a specific way of life that promotes peace or discourages violence.

Although law generally refers to a rule made by a government, it can also be used to refer to any strong rule made by an authority that must be followed. For example, your parents’ house rules might be described as laws if they must be strictly followed. As well, a behavior a person might do instinctively or spontaneously might also be called a law. For example, trying to save your life when you are in danger might be described as the law of self-preservation.

Scientific definitions for law

law

[ lô ]

A statement that describes invariable relationships among phenomena under a specified set of conditions. Boyle's law, for instance, describes what will happen to the volume of an ideal gas if its pressure changes and its temperature remains the same. The conditions under which some physical laws hold are idealized (for example, there are no ideal gases in the real world), thus some physical laws apply universally but only approximately. See Note at hypothesis.
