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.

What is Biological science?

the scientific study of life or living things

What is Physical science?

It deals with the study of nonliving things.

What is Physics? It deals with the understanding of

the fundamental laws of nature.  The branch of science concerned

with the properties of matter and energy and the relationships between them. It is based on mathematics and traditionally includes mechanics, optics, electricity and magnetism, acoustics, and heat. 

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?

because it employs the scientific method

What is Scientific Method?

It is the application of a logical process of reasoning to arrive at a certain law or principle that is consistent with experimental results.
