America was expanding economically in the 1800’s following the advent of the US constitution. William Austin Burt invented the typewriter in 1829 but it was not commercially successful. Typewriters allow people to write faster and neater than they can write with a pen or pencil. American company Sholes and Glidden released a Typewriter in 1879 that succeeded along with the rise of world war 2 they helped transform the american labor force and the roles women played in the economy

alschemes led to the development of chemicals that ignite based on friction John Walker invented matches almost by accident in 1826. matches, simple chemicals heads embedded on a stick are convenient in ways to start a fire, several improvements were made, without patent, leading to the matchbook in 1890 the match helped make smoking popular as well as barbecued leisure. attempts to amplify sound have been ongoing since ancient Greece Charles Wheatstone invented the concept of the microphone in 1827 microphones convert sound waves into electric signals for amplifications torch and transmission after wheatstone furthered progress on the electric telegraph its evolution into the telephone led thomas edison to invent the modern microphone. that is some history.

Economic growth in great Britain created a need to tunnel under the Thames River. Mark Brunel Patented a tunneling shield, inspired by the ship worm. The shield protects tunnel workers from cave-ins. Mark brunel was the first to successfully tunnel under the Thames River. which was completed in 1843. Increasingly sophisticated tunneling devices were increased the scope of modern tunneling accomplishments. Road designs began to improve in the 1700s, John McAdam invented the modern paved road method in 1816. the McAdam road is rather shallow, the layers of crushed stone is durable and efficient. McAdam advertised his road through books and by its own success, improvements in road-building led to the modern interstate system which is the backbone of our modern system. Hospitals were built by the church to provide charity to the sick and needy .Laennec invented his Stethoscope at a teaching hospital in France after watching a particular children’s game, The Stethoscope provides a non-intrusive way of investigating inside of our body, Laennec published his invention and researching in a book and the invention began to improve and spread rapidly.

The flour milling industry was booming in young America, but it was ripe for improvement. Oliver Evans was a creative inventor who got started by solving the millings industry problems. He developed process automation pioneered high pressure steam engines. He was a creative marketer who secured important clients and they promoted his inventions. The contributions made by Evan led to modern manufacturing technology and air conditioned environments. Gun firing mechanisms started becoming more sophisticated in the 1500s. John Forsyth invented the percussion cap system to solve problems he identified while duck hunting. it fired faster then older systems produced less smoke and worked in wet weather. Forsyth didn’t succeed in business but others especially in America did. the system led to modern bullet designs. Military necessity during aftermath of french revolution created demand for new ways to feed soldiers a french chef named Nicolas appert invented canning processing in response to the government prize money. canning cheaply preserves food taste and nutritional over time glass jars were quickly replaced by tin cans. armies were the primary market internally today canned food are important role in the diets of even first- world citizens.

Around 1800 economic growth began accelerating, In the west, this gave inventors greater access and ability to get their inventions out there. Inventions are tools that increase our efficiency letting us do more work in less time. inventors often face adversity, But they may also become wealthy and successful. Over the past 200 years, Newer and newer inventions have helped transform our world quicker then ever before. Ancient bridges were heavy and had several limitations. James Finley combined engineering and knowledge of ancient bridges to develop a newer and efficient design. suspension of bridges are relatively light and cheap structures given their strength others quickly copied his design. Their economic impact has been immeasurable. Networks of buried pipes began to proliferate during the middle ages . Fredrick Graff invented iron fire plugs to replace wooden ones. Fire hydrants provide a convenient supply of water for fire fighters. other towns copied the plug. Hydrants help firefighters save lives and property. Rail transport developed since the 1500s and by 1800 low pressure steaming hinted at high pressure engines Richard built the first locomotive from a small mobile high pressure steam engines in 1801 based on his mining experience locomotives enable efficient long distance mass transport people and goods public demonstrations and trials generated interest by 1900 the locomotive had helped transform Britain and America.
