Introduction to the World of Science
“Nature and Nature’s laws lay hid in night
God said, let Newton be!And all was light.
-Alexander Pope
Have you ever wondered why the sky is blue and the sunset red?
How and why things work?How do you hear and see?Why is life so different today
than four centuries ago?
What is Science?The word science comes from the
Latin "scientia," meaning knowledge
"knowledge attained through study or practice” (According to Webster's New Collegiate Dictionary)
Science refers to a system of acquiring knowledge…
Why?
Science is…a systematized body of
knowledge that is based on facts gathered through observations, experiences and experiments in order to formulate a verifiable conclusion or law that serves as basis of technology for the benefit of man and his environment.
Fields of science are commonly classified along two major lines:Natural sciences
-the study of the natural world
Social sciences-the systematic study of
human behavior and society
Applied Science- the application of the
theoretical sciences, like those in social and natural sciences.

It is a way of thinking.It makes you ask “why?” all the time.
Why does Physics can not be considered as a natural philosophy?
