What is Science?

Science word is derived from a Latin word Scientia , which mean ' to know ' or 'knowledge'.

 Definition of Science 
  • Science is an organised , systematic and formulated knowledge obtained through observations, experiments and verifications .
  •  Science is the systematic study of the structure and behaviour of the physical and natural world through observation and experiment.It is an organised body of knowledge on an object.
  • According to Einstein ," Science is an attempt to make the chaotic diversity of our sense experience correspond to logically uniform system of thought".
  • According to Webster's New Collegiate Dictionary " Science is knowledge covering general truths of the operation of general laws, esp. as obtained and tested through scientific method concerned with the physical world."
Scientific Method : The procedure , which the scientists use in the pursuit of science is known as scientific method. It consists of systematic observation , proposing a hypothesis and performing experiment which lead to a conclusion know as theory. Theory can be modified in light of new observation.

 Classification of Science
 1. Real Sciences (Natural Sciences)                    2. Social Sciences ( Pseudo Sciences)

   1. Real Sciences ( Natural Sciences) :The study of the natural world , in real sciences the laws and theories does not change with place, time and person.These are valid everywhere in the universe.
 For example : Newton's law of gravitation is valid for all masses in universe.

 2. Social Sciences ( Pseudo Sciences): The systematic study of human behaviour and society. It is a social paradigm or changing reality.
 For example : Economy of different countries is different.                       

In universe subject matter of Real sciences divided into two broad categories Living and Non Living things.
Living things are studied under Biological Sciences and Non living are studied under Physical Sciences.

CLASS 12TH PHYSICS EXPERIMENT To find the value of v for different values of u in case of a concave mirror and to find the focal length.

Image
To find the value of v for different values of u in case of a concave mirror and to find the focal length. Apparatus : Optical bench,concave mirror, optical needle,a meter scale. Theory: By Mirror formula , 1/f=1/v+1/u, f=uv/(u+v), where, u = distance of object from the pole of mirror v =  distance of image from the pole of mirror    f = focal length of concave mirror Ray diagram of concave mirror Procedure:  1 Take given concave mirror and turn its reflecting surface toward a distant object to obtain image on a sheet of note book. 2 Measure the distance between mirror and image formed on the sheet. This is the rough focal length of concave mirror. 3 Clamp mirror holder in one upright and fix two optical needles in two uprights on the optical bench. Place them close to each other at one end of optical bench. Adjust their heights so that tips of the needles are at the same height as the center of the mirror. Pierce a small piece of paper into the tip of the n

Branches of Science

Image
Science is broadly classified into two categories:  Natural Sciences or Real Science                                        Social Science Natural Science is the branch of science which deals with the study of universe (living organisms and non living systems) each and every thing.The law and theories in natural science does not change with place,people and time.So, its a study of  unchanged reality. Example : If an experiment is performed(correctly and accurately) by me or you its result does not change. Social Science is the systematic study of human behaviour and society. It is changing reality. Example: Economy of different countries is different. Initially, Science is studied under Philosophy .  But with the passage of time, as the man acquired more knowledge and experiment to validate facts(philosophy) science is considered as separate subject. In universe subject matter of Natural Science (Real Science) is studied  under two categories Living Organism and
