Education & Experience

All Firework-makers have three gifts. They are all equally important, and two of them are no good without the third. They are talent, grit and luck.

Teaching & Research

The subject I am going to recommend to your attention almost terrifies me. The variety it presents is immense and the enumeration of facts serves to confound rather than to inform. The subject is electricity.
