“Every great physical theory starts as a heresy and ends as a dogma”. Give some examples from the history of science of the validity of this incisive remark.

There are two sides of Physics, one which is orthodox and goes by convention like for example negative or positive signs assigned to the values and the other, which is the one which does not follow conventions. Now, the opinions which are against the conventions are called HERESY, while an established stuff is known as DOGMA. For example, Copernicus’s geocentric theory was a heresy, until it was proved and became a Dogma.
