The spinning wheel was also a precursor to the spinning jenny. [30] The earliest programmable machines were developed in ...
Sewing machines were invented during the first Industrial Revolution to decrease the amount of manual sewing work performed in clothing companies. Since the invention of the first sewing machine, generally considered to have been the work of Englishman Thomas Saint in 1790, [ 1 ] the sewing machine has greatly improved the efficiency and ...
A simple machine is a mechanical device that changes the direction or magnitude of a force. [1] In general, they can be defined as the simplest mechanisms that use mechanical advantage (also called leverage) to multiply force.

1974: The lithium-ion battery is invented by M. Stanley Whittingham, and further developed in the 1980s and 1990s by John B. Goodenough, Rachid Yazami and Akira Yoshino. It has impacted modern consumer electronics and electric vehicles. [509] 1974: The Rubik's cube is invented by Ernő Rubik which went on to be the best selling puzzle ever. [510]
