Paradigm Shift
What is a Paradigm Shift?
A paradigm shift refers to a major change in the basic concepts and practices of a scientific discipline. This term was made famous by philosopher Thomas Kuhn in his book “The Structure of Scientific Revolutions.”
Key Features
- Normal Science: Scientists work under a set framework or paradigm.
- Crisis: Anomalies or problems arise that the current paradigm cannot solve.
- Revolution: A new theory replaces the old, leading to a shift in thinking.
Examples
- Shift from Earth-centered (geocentric) to Sun-centered (heliocentric) models of the universe.
- Transition from Newtonian mechanics to Einstein’s relativity.
Importance
A paradigm shift transforms how scientists see the world and opens new directions for research. It is not just a small step forward, but a leap in understanding.
Conclusion
Paradigm shifts show that science is not always a steady path. Sometimes, it takes bold new ideas to replace old beliefs and bring about major progress.
