How These Four Inventions Changed the World

All humans are born with curiosity, but only some have turned this curiosity into action. Thomas Edison was one of those people.

For most of his life, he tried different things out of curiosity. Other times it didn’t work, but for those times when it did, Edison was able to change the world.

Over the next few years, people like Edison have taken their own leaps of faith in their pursuit of higher knowledge, and it resulted in these four inventions that changed the world in more ways than their inventors could have ever imagined:


What would we all do without electricity today? In a time when we are all highly dependent on electricity for our daily lives, it’s impossible to imagine a life without it. But there was actually a time when people didn’t have the luxury of electricity as a form of energy.

In 1831, however, British scientist Michael Faraday discovered the basic principles of generating electricity while Alessandro Volta also discovered the first practical method of electricity generation.

Since then, the use of electricity has evolved from just illuminating streetlights to now becoming a strong foundation of the modern industrial society.


One of the medical field’s biggest breakthroughs is definitely the invention of the antibiotic. The drug has saved millions of lives for so many years by inhibiting the growth of harmful bacteria on a patient’s body.

It was in 1877 when Robert Koch and Louis Pasteur first described a phenomena of the antibiotic drug called “antibiosis.” But it wasn’t until 1928 when Alexander Fleming identified penicillin, which is a chemical compound that has antibiotic properties.

Since then, antibiotics have spread rapidly all over the world and this drug continues to evolve to keep up with the newer strains of bacteria.


The camera is undoubtedly one of the best inventions that the world has seen and it has evolved immensely since Joseph Nicephore Niepce first used a sliding wooden box camera made by Charles and Vincent Chevalier in 1826.

This produced the first permanent photograph. Several years later, Eugene F. Lally had an idea of taking photographs of the planets while travelling through space.

This gave inspiration for the digital camera, which was built in 1975 by Kodak Engineer Steven Sasson. Today, cameras are already built in with mobile devices to make it easier to take photographs just by using a phone.

World Wide Web

It’s hard to imagine life without the world wide web when most of us rely heavily on it for information. It all started with Tim Berners-Lee, a British computer scientist who worked as a software engineering in Geneva, Switzerland.

He noticed that it was extremely difficult to share information back then, which led him to create a proposal called “Information Management: A Proposal” in 1989.

A year after, Tim already laid out the foundation of the world wide web through HTTP, URL and HTML technologies and we never looked back ever since.

Four inventions, four remarkable journeys that helped revolutionize the world that we all live in now.
