and explain how it has positively influenced human race.

Follow-up Questions:

· Why should we invest more in research?

· What is the single most important invention in your opinion?

Possible Answer:
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 human race.

This single invention of science has uplifted the human race towards prosperity and modern world. Think about a 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 in 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 realize 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 dark and have no vision to see at night. As human, we could have some lighting system if we did not know how to light a bulb but that would not have been so widespread without the invention of light bulb. Scientific inventions are interrelated and one invention or theory inspired and accelerates the invention of other important inventions.

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.

Discovery is exploring and finding out something that preexisted and nothing new to the world. Only people did not know till the discovery if it existed or not. Meanings of discovery are: to make known; reveal; disclose and from these meaning we can find that discovering means to reveal something of finding something that already existed but we did not know where. For instance, discovering America.

On the other hand Invention is creating/ giving idea or making something entirely new either using objects that preexist to create something entirely new or to create something that is first of its kind. Meanings of invention are: to come upon, to create. From the meaning we can say that invention is creating something entirely new of its kind. To invent this new thing the inventor may use preexisting materials but the final outcome has to be completely new. For instance, we say invention of telephone.
