Zitat des Tages von Francois Englert:
As an assistant in the polytechnic department, I was able to finance new studies and got my Physics Masters Degree in 1958 and my Ph.D. in 1959.
In 1955, I got my degree in electrical-mechanical engineering. I realised, however, that my interest was less in practical applications than in the understanding of the underlying theoretical structure, and I decided to learn physics.
Gravitational and electromagnetic interactions are long-range interactions, meaning they act on objects no matter how far they are separated from each other.
