Lid (container)

A lid, also known as a cap, is part of a container, and serves as the cover or seal, usually one that completely closes the object. A lid is often a type of closure.

History

Lids have been found on pottery dating back as far as 3100 BC. Ancient Egyptian canopic jars with lids held the organs of mummified bodies as early as 2686 BC. The coffee lid market is valued at roughly $180 million. An estimated 14 billion lids were sold in 2009 in the United States.

Some containers such as tubs or jars now have a plastic film heat sealed onto the container: this is often called a lidding film.

Cultural references

The word is used metaphorically, as in "keeping the lid on the secret" and "flipped his lid".

An old saying that you never have to put a lid on a bucket of crabs (because when one gets near the top, another will inevitably pull it down) is often used as a metaphor for group situations where an individual feels held back by others.

An old Yiddish saying, that "every pot will find its lid" refers to people finding an appropriate match in marriage.

System

A system is a set of interacting or interdependent component parts forming a complex/intricate whole. Every system is delineated by its spatial and temporal boundaries, surrounded and influenced by its environment, described by its structure and purpose and expressed in its functioning.

The term system may also refer to a set of rules that governs structure and/or behavior. Alternatively, and usually in the context of complex social systems, the term is used to describe the set of rules that govern structure and/or behavior.

Etymology

The term "system" comes from the Latin word systēma, in turn from Greek σύστημα systēma: "whole compounded of several parts or members, system", literary "composition".

History

According to Marshall McLuhan,

"System" means "something to look at". You must have a very high visual gradient to have systematization. In philosophy, before Descartes, there was no "system". Plato had no "system". Aristotle had no "system".

In the 19th century the French physicist Nicolas Léonard Sadi Carnot, who studied thermodynamics, pioneered the development of the concept of a "system" in the natural sciences. In 1824 he studied the system which he called the working substance (typically a body of water vapor) in steam engines, in regards to the system's ability to do work when heat is applied to it. The working substance could be put in contact with either a boiler, a cold reservoir (a stream of cold water), or a piston (to which the working body could do work by pushing on it). In 1850, the German physicist Rudolf Clausius generalized this picture to include the concept of the surroundings and began to use the term "working body" when referring to the system.
