Imagine the world today without aeroplane? This 20th century invention is no doubt one of the fastest means of transportation today. Before its advent, traveling around world used to be an uphill task which only nations and corporations could afford due to how capital intensive it used to be. The narrative has over the years completely changed as moving from one continent to another involves boarding a plane and spending some hours in it.

It was the Wright brothers, Wilbur and Orville, in 1903 who invented the first powered, sustained and controlled airplane flight. In working on different mechanical projects and keeping up with scientific research, the Wright brothers closely followed the research of German Aviator Otto Lilienthal. When Lilienthal died in a glider crash, they decided to start their own experiments with flight. Today, aviation has become a mega industry connecting people to different parts of the world. It has tremendously enhanced globalization and reduced the world to a global village. It has also enhanced nation economic and multinational corporation’s growth.

Light Bulb

It was US inventor, Thomas Edison, known to have invented bulb. However, the basic idea of using electricity to create light was first investigated over two centuries ago by the English Chemist, Humphrey Davy. He showed that when electric current flowed through wires, their resistance caused them to heat up to the point where the gave out light.

In 1879, Thomas Edison, came up with a ‘bright’ idea: the carbon filament light bulb that has solved the world’s lighting challenge. This invention has brought tremendous positive changes and development around the world as it has created beautiful scenery in the night ever since.


Despite being subjected under serious disagreement about who built the first telephone between Elisha Gray and Alexander Graham Bell, the later was awarded the first U.S. patent for the invention of the telephone in 1876. He is today recognized or credited as the inventor of telephone.

Telephone has evolved over the years with innovations, especially in the 21st century and revolutionized the world. It has made global communication easier, affordable and accessible.


Arguably, the first computer was the abacus or its descendant – the slide rule, invented by William Oughtred in 1622. However, Charles Babbage, an English mechanical engineer and polymath invented the concept of a programmable computer. He is recognized today as the father of modern computer.

Having passed through several developmental stages, computer has become indispensable device in our contemporary society. It is very useful such that no sector in the society can grow or survive without it. In fact, its usefulness cannot be over-stressed.


What began as a means of sharing information by government researchers in the 1960s has grown to become a mega and indispensable invention of the 20th century. Today, we use the internet virtually for everything, and for many people, it would be impossible to imagine life without it. The Advanced Research Projects Agency Network (ARPANET) became the first wide-area packet-switching network with distributed control and the first network to implement the TCP/IP protocol suite. Both technologies became the technical foundation of the internet.

In 1991, the internet changed again. A computer programmer in Switzerland name, Tim burners-Lee introduced the world wide web – not only sending file from one place to another but was itself a “web” of information that anyone on the internet could retrieve. The internet we know today is the brain child of Tim Berners-Lee.


The possibility of radio communication was made by an Italian inventor, Guglielmo Marconi. He sent and received his first radio signal in Italy in 1895. Similarly, the world’s first electronic television was created by an inventor named Philo Taylor Farnsworth in 1927.

Today, these two inventions are regarded as the most potent and effective means of mass communication. They are quite accessible and affordable. Although there are other means of mass communication, radio and television however, remain unbeatable in the business of information sharing. Today, they are found in every household to show how important they are.


Life would have been hell without automobile. It is to land what airplain is in the air. It makes land transportation easier and faster. It was a German inventor, Karl Benz, in 1886, birthed the modern car – he patented the three-wheeled motor car, known as the “motorwagon”. Today, it has become so useful and indispensable such that with it, the modern society would stand still.

Printing Press

Imagine a world without books? What we now have as the modern printing press has passed through several evolution such as Woodblock printing (200 AD), printing press (c. 1440), solid and ink printing (1987) and digital printing (1991). It is regarded as one of the most important inventions of all time. Its invention revolutionized bookmaking and distribution around the world. Also, the advent of mechanical printing press had contributed largely to the social change of the era and the age of enlightenment/science by which ideas were transported to various parts of the world.
