Human beings have always worked towards creating new inventions and changing the world along with that. But with new inventions, the ongoing development of technology is all ready to overcome human society. We have become so much dependent upon technology that it may overpower the whole human civilization someday. But there are some inventions by people that have changed the entire globe. Let’s have a look at the top 10 greatest modern inventions that have changed the face of our entire world.

10.Printing Press

Hand-inked books were for the higher class people that could not be afforded by the lower class people. But the printing press exponentially increased the speed with which the book copies could be made at an affordable price. It was used in academic institutions to print books, novels and plays. The politicians also printed pamphlets and papers to distribute among the public. By 1500, 20 million volumes were printed in Western Europe. Later on, the classical wooden blocked machine was replaced with movable metals that created efficiency and stability.

9.Light Bulb

According to historians, there were around two dozen people that were working towards inventing incandescent lamps in the 1800s. But it was Thomas Alba Edison who created the complete functioning light bulb in 1879 that had a generator and wiring with a carbon-filament bulb. In the beginning the bulb had a 40-hour life light but finally Edison made it to last up to 1500 hours.

8.Penicillin

PenicillinThis invention was an accidental one by Scottish scientist Alexander Fleming. He left his Petri-dish filled with bacteria with an open lid and noticed that the sample was contaminated with mold. The interesting thing was that the bacteria was dead everywhere where the mold was present. Later on in 1928 he found that the fungus was Penicillium on which the chemists worked for two decades to purify it and develop a drug called Penicillin. By 1944, it was produced in mass and was broadly used in World War II to rid the soldiers from different kinds of venereal diseases. Penicillin is still used today to fight diseases like gonorrhea, syphilis, pneumonia, cellulitis, etc.

7.Camera

Obscura-cameraJoseph N. Niepce, a retired French Military Officer was the first person to design a camera and was named as “Obscura”. It was made of two wooden boxes in which one box had a lens and the other one had a screen that was green in color. Then, he invented a diaphragm that assisted in clarity by sharpening the image. However, Friedrich Risner, a German Mathematician was the first person to discover the camera. As the time passed on, there were more developments leading to quality pictures that had color, flash and film. The invention of camera has helped people to capture beautiful moments and preserve them for the future.

6.Automobile, Airplane

automobiles-airplaneHenry Ford from USA was an intelligent man who wanted to replace wagon wheels with a modern form of transportation. He wanted to develop a car that was affordable, competitive and profitable. The rich people were ready to interest in this fast transportation and by 1901, 425 automobiles were made and sold. The city life drastically changed with automobiles that were fast easy. The farmers could carry huge loads to and from industries which was a major advantage for them.

The Wright Brothers were devoted to mechanics and their dream to fly like birds took many years of hard work and testing that led to the development of airplanes. The first “flying machine” rose to an altitude of 10 feet, travelled 120 feet in 12 seconds. After a few more successful flights, their invention was accepted making them famous throughout the world. With the invention of airplanes, tiresome journey that took days and months could be completed in a matter of hours in a safe and comfortable environment.

5.Calculator, Telephone and Smartphone

With this invention, people could perform large mathematical calculations and get the results within a few minutes. Today, students and professionals use them on a daily basis.

Another great invention is the telephone. There were many inventors that worked onto create telephone but Alexander Graham Bell was the first one to be awarded for this invention in 1876. With this invention, the use of letters to communicate reduced immensely. People could communicate with their relatives and friends and receive instant reply. As time passed on, mobile phones were developed in 1977 that were small and portable. Today there are smartphones that are improvised in a way that they carry features of a computer, camera, video recorder, calculator, music players and televisions. They are affordable and is owned by almost half the population of world.

4.Radio, Television and Internet

televisionRadio was invented by Nikola Tesla and Guglielmo Marconi in 2001. The first radio telegraph message was sent from England to Canada. It became popular in no time with one way communication and broadcasting news, music and game commentary.

Television is a great modern invention done by J.L. Baird in 1926. The core concept of radio was manipulated to give a visual output. It took almost 2 decades for television to become a household utility. It is mainly used for entertainment purpose and communication in real time.

The internet does not need any kind of introduction. Internet is defined as the global system of interconnected computer networks that is used by people all around the world. There were many people who put their head together for this creation but the credit is given to Lawrence Roberts, a computer scientist. With this invention, people are capable to exchange emails, documents, photos and even phone calls. Long distance communications is possible making the world seem smaller and closer to us.

3.Robots, Artificial Intelligence

Robots-Artificial-IntelligenceRobots are designed to resemble human beings that are capable to do all human related work with more efficiency without being tired. AI, on the other hand are machines that use ultra-technology to perform tasks without human guidance. They are faster, more reliable and accurate than computers in completing their tasks. The Hollywood fiction movies are not that far from being real.

2.Banking, Credit Cards

credit-cardsThe start of banking was in the early renaissance Italy in 1472 from a bank called Monte dei Paschi di Siena. With this invention, people can get loan, deposit money and gain interest over a period of time. Trade and business has blossomed with banking. The credit card was invented as an electronic way of banking by John Biggins in 1946. This led to transactions between customers and traders. Credit cards are popularly used for local and international banking.

1.Electricity

electricityMichael Faraday from England and Joseph Harry from US both worked to build models of electricity generators in the 1800s. When Volta invented the cell, ac and dc currents helped in transmissions of electricity. All the gadgets that have been developed later are mostly based on electricity. Without electricity, our day to day life may turn into mishap.
