TheMachine Age[1][2][3] is an era that includes the early-to-mid 20th century, sometimes also including the late 19th century. An approximate dating would be about 1880 to 1945. Considered to be at its peak in the time between thefirst andsecond world wars, the Machine Age overlaps with the late part of theSecond Industrial Revolution (which ended around 1914 at the start of World War I) and continues beyond it until 1945 at the end of World War II. The 1940s saw the beginning of theAtomic Age, wheremodern physics saw new applications such as theatomic bomb,[4] the firstcomputers,[5] and thetransistor.[6] TheDigital Revolution ended the intellectual model of the machine age founded in the mechanical and heralding a new more complex model ofhigh technology. The digital era has been called theSecond Machine Age, with its increased focus on machines that do mental tasks.
TheYamato and otherbattleships in World War II were the heaviest artillery-carrying ships ever launched. They proved inferior to aircraft carriers and missile-carrying warships.Somelocomotives built in the mid-20th century were the heaviest ever.
Gigantic production machinery, especially for producing and working metal, such as steel rolling mills, bridge component fabrication, and car body presses
Mass-produced governmentpropaganda through print, audio, and motion pictures
Replacement of skilled crafts with low skilled labor
Growth of strong corporations through their abilities to exploiteconomies of scale in materials and equipment acquisition, manufacturing, and distribution
Conflicts between nations regarding access to energy sources (particularly oil) and material resources (particularly iron and various metals with which it is alloyed) required to ensure national self-sufficiency. Such conflicts were contributory to two devastatingworld wars.
