physics facts

The word Physics comes from the Greek word fusis mini nature. Its Sanskrit equivalent is Bhautika i.e. the physical world. In Physics we attempt to explain diverse physical phenomena in terms of a few concepts and laws. The effort is to see the physical world as manifestation of some universal laws in different domains and conditions.

In Physics we study different forms of matter, their properties and the transformations that they undergo. It is a major signs dealing with fundamental constitutes of universe, the forces they exert on one another and the results produced by these forces. Physics a basic discipline in the category of natural sciences which also includes other disciplines like chemistry and biology.

Major Branches of Physics

Acoustics It is the study of production and properties of sound
Atomic Physics It is the study of structure and properties of an atom.
Biophysics It applies tools of physics to life processes
Cryogenics It is the study of low-temperature
Electrodynamics It is the analysis of relationship between electrostatic and magnetic fields.
Fluid Physics It deals with movement of liquid and gases
Mechanics It deals with behaviour of object and system to various forces.
Nuclear/Modem Physics It is concerned with structure and properties of atomic nucleus and their reactions.

Physicists and their Achievements in Unification

Name of the Physicists Years Achievements in unification
Issac Newton 1687 Unified celestial and terrestrial mechanics showed that the same laws of motion and the law of gravitation apply to both the domains.
Hans Christian Oersted
Michael Faraday
1820
1830
Showed that electric and magnetic phenomena are inseperable aspects of a unified domain; electromagnetism.
James Clerk, Maxwell 1873 Unified electricity, magnetism and optics; showed that the light is an electromagnetic wave
Sheldon Glashow, Abdus Salam, Steven Weinber 1979 Showed that the week nuclear force and the electromagnetic force could be viewed as different aspects of a single electro-week force.
Carlo Rubia, Simon Vander Meer 1984 Verified Sperry mentally the predictions of that theory of electro-week force.
