Timeline of Invention
In music, an invention is a short composition with two or three part counterpoint. See Invention (music)

An invention is a novel device or technique.

One question that society often asks is, "What conditions lead to the development of an invention?" There are two main opposing viewpoints on this; one school of thought argues that a lack of resources leads people to invent, whereas, the other school of thought argues that only an excess of resources will result in inventions.

Castles in the air (or castles in Spain) are creative ideas which cannot be created due to more earthly considerations. The history of invention is full of such castles, as inventions aren't necessarily invented in the order that is most useful. For example, the design of the parachute was worked out before the invention of powered flight. Other inventions simply solve problems for which there is no economic incentive to provide a solution.

Following the terminology of political economist Joseph Schumpeter, an invention differs from an innovation. While an invention is merely theoretical (even though it might have been filed with the Patent Office), an innovation is an invention that has been put into practice.

Significant inventions, arranged in chronological order

Note: Dates for inventions are often controversial. Inventions are often invented by several inventors around the same time, or may be invented in an impractical form many years before another inventor improves the invention into a practical form. Where there is ambiguity, the date of the first practical, fielded, version of the invention should be used here.
