Describe an invention that changed the world
You should say:
What the invention was
What it can do
How popular it is
Why it is an important invention
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.
