WHAT IS SCIENCE ??????   The word science probably brings to one’s mind many different pictures: extremely large textbooks,laboratories,coats and microscopes,bombs and military,an astronomer peering through a telescope, newton’s equation scribbled on a chalkboard,space,Einstein’s photoelectric,numbers effect,genetics......All these images reflect some spheres of science,but none of them provides a full picture of what science really is, because science has many facets.   DEFINITION(s) Science is the intellectual and practical activity encompassing the systematic study of the structure and behaviour of the physical and natural world through observation and experiment. Science is the pursuit and application of knowledge and understanding of the natural and social world following a systematic methodology based on evidence. Science is knowledge gained by systematic and logical study in any branches of physical, chemical or natural sciences, which is gained through observa...

kinetic theory of matter structure of matter: (a) E vidence that matter is made up of tiny indivisible particles[called ATOM S ],can be traced back to the time of the ancient Greeks.According to Sir John Dalton's theory in 1810.HE postulated that ATOMS can neither be created nor destroyed and are the smallest particle that cannot be broke down. The highlighted clause above indicates that it can be gotten from any substance[yam,paper,wool,metal,can] by the continually breaking into small bits until it cannot be broken down again.this tiny was named atom.The atomic theory of matter states that all matter[Gas,Solid,Liquid,...] are made up of atom which are constantly moving about a mean fixed point. The experiment of atomic structure is the Brownian motion[movement] performed by Scottish biologist Robert brown in 1827,where he looked under a microscope and observed the motion of particle of pollen grains suspended in water.This was an unintentional discovery by Robert,Whom he notice...
