Seed Drill
Jethro Tull invented the seed Drill. His seed drill would sow seed in uniform rows and cover up the seed in the rows. Up to that point, sowing seeds was done by hand by scattering seeds on the ground. Tull considered this method wasteful since many seeds did not take root. -
Steam Engine
The steam engine changed the world by overcoming the limitations of men and horses. The steam engine was the driving force behind the industrial revolution, and allowed humans to harness the power of steam and to allow machines to do the grunt work and allow factories to reach speed of production never before seen in the 18th century. -
Spinning Jenny
The spinning jenny changed the world in 1764. The spinning jenny allowed for mass production of yarn which was in very high demand at the time. The spinning jenny was invented by James Hargeaves. -
Improved Stean Engine
The James Watt steam engine worked in that: water was heated using coal in a boiler and this water produced steam which was allowed to expand by pushing against a piston or turbine, whose motion was used to operate the engine. -
Cotton Gin
The cotton gin changed society by making cotton easier to process, and creating more jobs in the newly built textile mills. Farmers were able to plant more cotton. The northern United States and England built more textile mills. -
Improved Steel Manufacturing
English engineer and inventor, Henry Bessemer's name is widely known in connection with the Bessemer process for the manufacture of steel. Another invention from which Henry Bessemer made his first fortune, was a series of six steam-powered machines for making very fine brass powder which was used as a gold paint. -
Pasteurisation
The heat of pasteurization is enough, however, to kill the beneficial lactic acid or souring bacteria—lactobacillus acidophilus—which help to synthesize B vitamins in the colon and hold the putrefactive bacteria in check. Raw milk will eventually curdle and clabber if allowed to sit at room temperature because of the lactic acid bacteria, which, as mentioned, hold down the putrefactive bacteria population. Pasteurized milk, having no such protection, will rot. Hence, the irony of pasteurization -
Telephone
The telephone had several positive impacts on society. This would include the creation of jobs since there are several job positions that the telephone brought about. This would include telephone operators and messenger boys during the earlier years of the advent of the telephone. -
Phonograph
The phonograph changed the world by allowing people to share music. It also changed the world by making it easier to reproduce sound. The phonograph was a step toward the telephone and other technology that reproduced sound. -
Light Bulb
The light bulb changed the world because it allowed for the use of light by electricity. Before that the only light provided was either natural daylight or by candle light. It revolutionized how people lit their homes. -
Kinetoscope
It changed our lives because now we can capture things in one place and show the footage to others who were not present at that moment. -
Automobile (assembly Line)
Yet, the effect on city life has been, if anything, more prominent than the effect on the farms. The automobile has radically changed city life by accelerating the outward expansion of population into the suburbs. The suburban trend is emphasized by the fact that highway transportation encourages business and industry to move outward to sites where land is cheaper, where access by car and truck is easier than in crowded cities, and where space is available for their one or two story structures.
