Recently third domain in between is also thought of with name Mesoscopic Physics. Microscopic domain I ncludes atomic, molecular and nuclear phenomena. Macroscopic domain includes phenomena at the level of Laboratory, terrestrial and astronomical scales. The scope of Physics can be divided in to two domains Macroscopic and Microscopic. For example a complex thermo dynamical system can be understood by the properties of its constituent like kinetic energy of molecules and atoms. It is supposed to be the heart of Physics. To understand or to derive the properties of a bigger or more complex system the properties of its simpler constituents are taken into account.This is principle of Unification.Įxample: Phenomena of apple falling to ground, moon revolving around earth and weightlessness in the rocket, all these phenomena are explained with help of one Law that is, Newtons Law of Gravitation.
There are two principal thrusts in Physics.Physics is a study of basic laws of nature and their manifestation in different phenomenas.Natural Sciences can be broadly divided in three branches namely Physics, Chemistry and biology To explain bending of light a new Wave-theory was formed, and then to explain photoelectric effect help of quantum mechanics was taken. For example to explain different phenomena in light, theories are changed.Sometimes the existing theory is unable to explain the new observations, hence either new theories are formed or modification is done in the existing theories. Observations and experiments need theories to support them.There is no ‘final’ theory in science and no unquestioned authority in science.

Verification or falsification of theories.Qualitative and quantitative reasoning,.Scientific Method Scientific methods are used to observe things and natural phenomena. It is a systematic attempt to understand natural phenomenon and use this knowledge to predict, modify and control phenomena. This knowledge is organized so that it become well connected and logical. It is human nature to observe things and happenings around in the nature and then to relate them.
