Question

What are the two principal thrusts in physics?

Answer 1

Answer:

Explanation:TWO MAIN THRUST IN PHYSICS ARE (1)UNIFICATION (2)REDUCTION

Explanation:

the principal of thrusts in physics are unification and reduction.

in unification, Diverse phenomena of nature are expressed in few terms of laws and concepts. for example,the law of gravitation. It explains falling of objects on earth,planetary motion, motion of moon, etc.

Only one law explains so much phenomena! it becomes convenient for us to study only one law and understand too many phenomena

2. reduction, in this we derive simpler equations form the complex systems from its constituent simpler parts. for example, BOHR radius, it is a very complex formula, but now we use only the simpler version of it, I.e. r1×n/Z

where n is the no. of shell, Z is the atomic number and r1 is the constant, radius of 1st shel l of hydrogen

Answer 2

1. Unification: When all the smaller properties of a system are combined and studied as a whole with the help of one grand property or a theory, then the approach is known as unification.
2. When a system's bigger properties or macroscopic properties are derived from individual smaller parts the approach is known as reductionism.
