Question

Though the statement quoted above may be disputed, most physicists do have a feeling that the great laws of physics are at once simple and beautiful. Some of the notable physicists, besides Dirac, who have articulated this feeling, are : Einstein, Bohr, Heisenberg, Chandrasekhar and Feynman. You are urged to make special efforts to get access to the general books and writings by these and other great masters of physics. (See the Bibliography at the end of this book.) Their writings are truly inspiring !

Answer 1

There is no doubt that great laws of physics are at once so simple and beautiful and are easy to grasp. For example, let us look at some of these :
(i) E = $m{c}^2$ is a famous Einstein's mass energy equivalence relation which has a great impact not only on the various physical phenomenon but also on the human lives.
(ii) Plank's quantum condition i.e. E = h$\nu$ is also a simple and beautiful equation and it is a great law of Physics.
iii) $\sigma$x . $\sigma$p > h / 4$\pi$ is Heisenberg's Uncertainity Principle which is also very simple, beautiful and interesting. It is a direct consequence of the dual nature of matter.

(iv) $\lambda$= h/p is also a famous equation in Physics known as de-Broglie equation. It is again simple and beautiful.
