I ... began my career as a wireless amateur. After 43 years in radio, I do not mind confessing that I am still an amateur. Despite many great achievements in the science of radio and electronics, what we know today is far less than what we have still to learn.

The will to persevere is often the difference between failure and success.

Freedom is the oxygen without which science cannot breathe.

I have learned to have more faith in the scientist than he does in himself.

Nobody can be a success if they don't love their work.

If we are to become the masters of science, not its slaves, we must learn to use its immense power to good purpose. The machine itself has neither mind nor soul nor moral sense. Only man has been endowed with these godlike attributes. Every age has its destined duty. Ours is to nurture an awareness of those divine attributes and a sense of responsibility in giving them expression.

The thrill, believe me, is as much in the battle as in the victory.
