This shift dramatically altered the look of cities and made it possible for much larger numbers of people to live and work in them. Before the advent of mechanized agriculture, farmers had to devote a portion of their acreage to raising grain to feed horses and mules since these animals helped them to work the land.
By the s, farmers were already using steam-powered machines, but the machines were cumbersome and dangerous, since a spark from the boiler could set fire to a field.
But an Iowa inventor named John Froelich devised a solution. With the help of his mechanic, Will Mann, Froelich replaced the steam apparatus with a single-cylinder gasoline-powered engine. Gas-powered tractors proved pivotal in boosting agricultural productivity and enabling American farmers to feed a growing population. The first safety razor Invented by King Gillette, c.
But in , a traveling salesman named King Gillette got the idea for a razor with a handle that used a tiny, disposable metal blade that could be discarded in the trash and replaced when it eventually got dull. In , Gillette and Nickerson formed the American Safety Razor Company, and Gillette obtained a patent for the safety razor with disposable blades in Guglielmo Marconi, Italian physicist and radio pioneer. The invention of the telegraph in made it possible for people to communicate for the first time instantaneously over long distances, but they still were limited by the need to have miles of wires installed to connect the sender and the receiver.
But starting in the mids, an Italian inventor named Guglielmo Marconi developed a better method—transmitting messages through radio waves. List of Partners vendors. Share Flipboard Email.

It was made in its hundreds throughout the 18th century,. This was an improvement on a crude steam powered machine built by fellow Englishman, Thomas Savery, whose machine had no moving parts. It was, however, still dreadfully inefficient; it required huge amounts of coal to function.
It was introduced commercially in and became the basis for future developments that saw the steam engine become the main source of power for a large variety of British industries.
The journey had an average speed of c. This was the most advanced locomotive of its day, winning the Rainhill trials as the only one of five entrants to complete the one mile track in Lancashire.
The trials had been put on to test the argument that locomotives provided the best propulsion for the new Liverpool and Manchester Railway. The next year they installed the system along thirteen miles of Great Western Railway from Paddington to West Drayton. It was the first commercial telegraph in the world. In America, the first telegraph service opened in when telegraph wires connected Baltimore and Washington D.
One of the main figures behind the invention of the telegraph was the American Samuel Morse, who also went on to develop Morse Code to allow the easier transmission of messages across telegraph lines; it is still used to this day.
