When you're certain you cannot be fooled, you become easy to fool.

Had we not pursued the hydrogen bomb, there is a very real threat that we would now all be speaking Russian. I have no regrets.

The main purpose of science is simplicity and as we understand more things, everything is becoming simpler.

In our educational institutions applied science may almost be described as a "no-man's land."

There's no system foolproof enough to defeat a sufficiently great fool.

Today, nothing is unusual about a scientific discovery's being followed soon after by a technical application: The discovery of electrons led to electronics; fission led to nuclear energy. But before the 1880's, science played almost no role in the advances of technology. For example, James Watt developed the first efficient steam engine long before science established the equivalence between mechanical heat and energy.

My experience has been in a short 77 years that in the end when you fight for a desperate cause and have good reasons to fight, you usually win.
