Wait man. What is science?

Hey , who are you?

I am Rumba, an ancient man.Now tell me what is science.

Ok. Science simply means knowledge.

It also has detailed explanations given by scientists.

Wait a minute. I think you were the people who invented fire.

How do you know that we were the people who find fire?

That is what we call history. Through history we studies about our pasts. That is

about our ancestors like you.We have advanced technologies through which we can even find that at what time an animal was born with the help of its

fossils or bones.

So you guys are more advanced than us.

I would like to know about development of science.

OK. Lets take a trip. Lets go...

The word science simply means knowledge. We can see in dictionaries the meaning is given as a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.

Science cannot be developed within a day or a year but it takes hundreds of years for the development of science from ancient science to the kind of science in todays world.

Oh, so we have our discussion in the right day. Isn’t it?

You are right!
