In the last few decades, science has progressed much.

Numerous inventions have changed the living style of people and also ways of working.

But Here I would like to describe an invention that has made people's lives easier compared to the past.

It is the invention of the light bulb which has removed the darkness from people's lives.


It was invented by Thomas Edison in 1879.

Before the invention of the light bulb, people were dependent on natural light and there would be no nightlife without the bulb.

Their work also relies on daylight and they had to sleep early.

But after the discovery of the light bulb,
Individuals have become more productive, they prefer to do their work till midnight as it extended the working hours and also declines the sleeping hours.

Moreover, it has brought new hopes and aspirations for the people because the bulb allowed travellers to travel at the night.

It allows people to have more leisure time and activities.

It also made it easier for people to perform work-related tasks and study.

In the 20th century, Nick Holonyak discovered the LED bulb which is the upgrade version of the bulb, that is more eco friendly.

This invention enhances the beauty of houses as the masses use these bulbs for decoration purposes.

Nowadays, scientists use bulbs in outer space to invent other things.

I think now we can't imagine our life without bulb.

So this was the invention that has changed the lives of people.
