"All these fifty years of conscious brooding have brought me no nearer to the answer to the question, 'What are light quanta?'

Nowadays every Tom, Dick and Harry thinks he knows it, but he is mistaken. …"

                                   - Albert Einstein

        "A new scientific truth does not triumph by convincing its opponents and making them see the light,

but rather because its opponents eventually die, and a new generation grows up that is familiar with it."

                                    - Max Planck
