Top 10 Inventions that Changed the World

Internet

-The Internet has revolutionized the way people obtain and disseminate information. Billions of people use the Internet every day and without it society would process at a much slower and economic growth would be nowhere near where it is today. The Internets beginnings can be traced to computer scientist Lawerence Roberts, who was working for the Department of Defense on a way for computers to communicate within the agency. 



Telephone

-The telephone revolutionized communication throughout the world, as people were only able to converse long distance via snail mail, which would take several days if not weeks. The telephone was invented by Alexander Graham Bell in 1876, as he was the first one to have a communication device that could relay audible signals to the person using it. 



Printing Press 

-Johannes Gutenberg invented the printing press around 1440. The printing press is in my opinion the most important invention of all time. It represents the beginning of recorded history as well as the widespread dissemination of knowledge. Gutenberg created a hand mold for moveable type that enabled nearly 3,600 pages to be produced in a single day. 

Light Bulb

-Thomas Edison invented the light bulb in 1879, which was merely a bulb connected to a generator via electrical wiring. The light bulb enabled people to do many more things at night including reading and cooking. The light bulb had a huge impact on people productivity levels as they can do anything at anytime now instead of only when there was sunlight. People use to go to bed when the sun went down, but with the invention of the light bulb people now go to bed much later in the evening.



Airplane

-The Wright Brothers are credited with inventing and build the airplane that completed the first successful flight. The airplane has enabled people to move across the globe in much shorter amounts of time, making traveling more pleasurable and economically feasible. For example, the airplane enables us to travel from the United States to Europe in 10 hours, when a boat ride would take 3 months. 

Combustion Engine

-The combustion engine is the basis for travel, as it is the basis for how airplanes and cars are able to move at the speeds that they do. The combustion engine turns chemical energy into mechanical work. The engine releases a high temperature gas that applies force to the pistons in the engine, thus moving them. The combustion engine was instrumental in the success of the Industrial Age, as it replaced hand tools with more efficient mechanical technology.



X-Ray

-The X-ray machine was developed in 1895 and had an immediate change on how doctors detected disease and diagnosed injuries. It has a huge impact on the daily lives of people, from medical detection to high tech security at airports. 

Penicillin

-Founded by Alexander Fleming in 1928. It has been instrumental in the killing of bacterial diseases and does not cause harm to humans. Penicillin became mass marketed to the public around 1944, and enjoy instant success and effectiveness. 



Refrigerator

-The refrigerator has had an immense impact on the way people interact with food. With refrigeration, people are able to store foods for longer periods of time and do not have to constantly go to the market. The Refrigerator enables us to also quickly cool things down, as opposed to having to use ice. The refrigerator has enabled us to keep more fruits and vegetables on hand, thus increasing our nutrition. 



Wheel

-The wheel was invented in 3500 B.C. and revolutionized the way that people moved themselves and their cargo around. The wheel had a huge impact on agriculture at that time, and today is used everywhere including airplanes, which were an invention that was named above. The wheel is instrumental in having time effective transportation, which is crucial to our economy and making all humans daily lives easier.
