The two principal thrusts in physics are
The two principal thrusts in physics are
Show Hint
Modern physics advances mainly through two approaches: unification of different forces and phenomena, and reduction of complex systems to fundamental laws.
Updated On: Jun 18, 2026
- Diversification and complexification
- Unification and simplification
- Unification and reduction
- Diversification and simplification
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understand the objective of physics.
Physics aims to explain a wide variety of natural phenomena using a small number of fundamental principles and laws. Scientists continuously search for connections between apparently different phenomena.
Step 2: Meaning of unification.
Unification refers to combining different physical phenomena under a common theoretical framework. Examples include Newton's unification of terrestrial and celestial mechanics and Maxwell's unification of electricity and magnetism into electromagnetism.
Step 3: Meaning of reduction.
Reduction means explaining complex systems and phenomena in terms of more fundamental laws and constituents. For example, thermodynamics can be understood through the microscopic behavior of atoms and molecules using statistical mechanics.
Step 4: Analyze the options.
Diversification and complexification are not the primary goals of physics. Physics seeks simpler and more fundamental explanations rather than increasing complexity. The accepted description of the two major thrusts of physics is unification and reduction.
Step 5: Final conclusion.
Therefore, the correct answer is \[ \boxed{\text{Unification and reduction}} \]
