Some of the best actors in the world are very exterior actors, Anthony Hopkins being one of them. He knows exactly how to turn his face to get a certain expression. He knows exactly what to do with eyes, and with his voice. It's very exterior.

With this in mind, for some twenty years I have set myself as my particular task the experimental investigation of the connexion between change in the structure and change in the spectra of chemical atoms.
