Question 10 : In quantum mechanics, Werner Heisenberg is famous for which fundamental principle, often cited alongside Schrödinger's work?
Possible answers:
- The superposition principle
- The exclusion principle
- The uncertainty principle
- The complementarity principle
Explanation: Heisenberg's uncertainty principle (1927) states that it is impossible to simultaneously measure with precision both the position and the momentum of a particle. The more precisely one is known, the less precisely the other can be known, which is a fundamental property of nature and not a technological limitation.
