Humans can be very innovative. During our existence on the Earth we have invented some amazing and useful things that are making our lives much easier.
Here is a list of the most popular inventions we are using almost every day:
The wheel was invented in 3500 B.C. like a result of the humans needs to transport more staff to far distance. Most important part of the invention was connecting the rolling cylinder to not-moving platform (wheel-and-axle concept), an axle connected with two perfectly round wheels with hole in the center. The invention of the wheel changes the human’s life significantly, improving the transport of gods and people to far distances.
Before compass was invented sailors where using the stars for navigation, but that was not useful during the day. The compass was invented by the Chinese Han Dynasty between 300 B.C. and 200 B.C. and was made of a naturally-magnetized iron ore (lodestone). Invention of the compass enables safe navigation and contributes in discovering new worlds and raising the sea trade.
The Printing Press
The first mechanized printing press that transfers the ink to paper was made in 1440 from Johannes Gutenberg, German inventor. Invention of the printing press enables making books copy faster and providing humans to gain knowledge easily. By 1500, around 20 million book copies were made in Europe.
The Internal Combustion Engine
The internal combustion engine enables energy released with combustion of a fuel to be converted into mechanic work. Many scientists have made designs and during the Industrial Age started its wide usage. This engine was the basis for inventing many machines like cars and aircrafts.
The first practical telephone was patented in 1876 by Alexander Graham Bell, Scottish scientist and inventor. His deaf mother and wife were the main inspiration. The invention of the telephone brought revolution in the global communications.
The Light Bulb
In 1879, Thomas Edison was the first scientist who builds fully functional lightning system. The invention enables people to be active when there is no natural light. Now day’s light bulb is widely used because of its easy embodiment into electrical systems, low-cost and energy efficiency.
The most famous drug was discovered in 1928 by Alexander Fleming, Scottish scientist. Penicillin is effective against many bacterial infections and its massive production started during the World War II. Because of its extensive usage many bacteria types became resistant to the drug.
Lawrence Roberts, American computer scientist and group of other people build the ARPANET, predecessor of the Internet in the 1960s. A “packet switching” data transmission method was used to connect the computers in a network for exchanging information. Today, billions of people are using the Internet all over the world.
