Explain the statement : "Science is always dynamic". with example.

Explanation

`to` Science is ever dynamic. There is no .final. theory in science.
`to` As observations improve in detail and precision or experiments yield new results, theories must account for them, if necessary, by introducing modifications.
`to` Sometimes the modifications may not be drastic and may lie within the framework of existing theory
`to` For example, when Johannes Kepler (1571-1630) examined the extensive data on planetary motion collected by Tycho Brahe (1546 - 1601).
`to` The planetary circular orbits in heliocentric theory (Sun at the centre of the solar system) imagined by Nicholas Copernicus (1473 1543) had to be replaced by elliptical orbits to fit the data better.
