question_answer 14)

"It is more important to have beauty in the equations of physics than to have them agree with experiments". The great British physicist P. A. M. Dirac held this view. Criticize this statement. Look out for some equations and results in this book which strike you as beautiful. 

Answer:

Dirac was his genious best when he pronounced this statement. A physical equation must be simple and hence beautiful. It will automatically agree with the experimental results. For example, consider Einstein mass-energy relationship : This simple equation not only governs energy generation in the sun and the other stars but it is also mainly responsible for energy generation on the earth from the processes of nuclear fission and nuclear fusion. However, it is not always true. Although some equations of Quantum Mechanics and Theory of Relativity are highly cumbersome and difficult to understand, yet they agree with the experiments.
