Ok guys , i will tell you what is meaning of revolution? 

A revolution is a fundamental change in political power or organizational structures that takes place in a relatively short period of time when the population rises up in revolt against the current authorities. Aristotle described two types of political revolution:

1.       Complete change from one constitution to another

2.       Modification of an existing constitution.

Revolutions have occurred through human history and vary widely in terms of methods, duration, and motivating ideology. Their results include major changes in culture, economy, and socio-political institutions.

Scholarly debates about what does and does not constitute a revolution center on several issues. Early studies of revolutions primarily analyzed events in European history from a psychological perspective, but more modern examinations include global events and incorporate perspectives from several social sciences, including sociology and political science. Several generations of scholarly thought on revolutions have generated many competing theories and contributed much to the current understanding of this complex phenomenon.

The first of these is an analysis of the stages by which revolutions in science progress from the inception of a revolutionary idea to the acceptance and use of a new science bye a sizable number of scientists
