It is really tough to pick one particular scientific invention that had

positively influenced human race as there are possibly hundreds and thousands of

such inventions. I would like to pick the 'Light Bulb' as one such invention

that has very positively influenced the human race.

This single invention of science has uplifted the human race towards

prosperity and the modern world. Think about the world without any lights in the

dark and we would have been no different than living in a cave. The great

scientist Thomas Edison is credited to invent the light bulb and till then many

improvements have been done to it.

The bulb is the main source of illumination and light at night time when the

Sun is hiding at the opposite side of the world. We are so habituated with the

electricity and light bulbs that we might wonder if it is a life-changing

invention or not.

But think about living your life for few days without the bulbs and then you

would realise the true importance of this single invention. Some may argue that

fuel powered lighting system could have been alternative to it, but the reality

is that that would have been too expensive and could not have been an easy

source for lighting the houses,

Think about the other living beings other than human; they mostly get back to

their living place in the evening and except some nocturnal animals and birds,

most of them stay at their living place till the morning.

They rarely do anything at night and that's because they are afraid of the

dark and have no vision to see at night. As the human, we could have some

lighting system if we did not know how to illuminate the light bulb but that

would not have been so widespread without the invention of the light bulb.

Scientific inventions are interrelated and one invention or theory inspired and

accelerates the invention of other important inventions.

The Light bulb is one such invention that has inspired the invention and

research of other inventions. This is the single invention that has made us free

from being active only at day time when the sun is there.
