Many of the technological and architectural innovations were of British origin. [3] [4] By the mid-18th century, Britain was the world's leading commercial nation, [5] controlling a global trading empire with colonies in North America and the Caribbean.
The plow is a tool used in farming for initial cultivation of soil in preparation for sowing seed or planting. It has been a basic instrument for most of recorded history, and represents one of the major advances in agriculture. In modern use, a plowed field is typically left to dry out, and is harrowed before planting.
The Second Industrial Revolution, also known as the Technological Revolution, [1] was a phase of rapid scientific discovery, standardisation, mass production and industrialisation from the late 19th century into the early 20th century.
The best-known were James Eddy (1731–1809) and his brother-in-law William Wadill, also an engraver. Most planters, however, purchased English-made silver. [11] In Boston, goldsmiths and silversmiths were stratified. The most prosperous were merchant-artisans, with a business outlook and high status.
A technological revolution is a period in which one or more technologies is replaced by another new technology in a short amount of time. It is a time of accelerated technological progress characterized by innovations whose rapid application and diffusion typically cause an abrupt change in society.
But the rate of progress is also dependent on other factors, such as the number of researchers, the level of funding, and advances in technology. Thus the number of new species of mammals discovered between the late 1700s and late 1800s followed grew exponentially before leveling off in the 1900s; the general shape is known as the logistic curve .
The first major technologies were tied to survival, hunting, and food preparation. Stone tools and weapons, fire, and clothing were technological developments of major importance during this period. Human ancestors have been using stone and other tools since long before the emergence of Homo sapiens approximately 300,000 years ago. [5]
