How science developed to date???!!!

3. Wait man. What is science?

4. Hey , who are you?

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

6. 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.

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

8. 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.

9. So you guys are more advanced
than us.
I would like to know about
development of science.

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

12. 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.

36. Now I think you have an idea about
Development in science.

37. Yes. Thank you for helping me to
explore the world of science.

38. Do you know what is todays
speciality?

39. No. What is it?

40. Today is february 28 .
National Science day.
It is the birthday of the famous
scientist CV Raman who found
raman effect.

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

42. You are right!
