Science walks forward on two feet, namely theory and experiment.

My idea of an educated person is one who can converse on one subject for more than two minutes.

Two erroneous impressions ... seem to be current among certain groups of uninformed persons. The first is that religion today stands for mediaeval theology the second that science is materialistic and irreligious.

Fullness of knowledge always and necessarily means some understanding of the depths of our ignorance, and that is always conducive to both humility and reverence.

Indeed, I suspect that the changes that have taken place during the last century in the average man's fundamental beliefs, in his philosophy, in his conception of religion, in his whole world outlook, are greater than the changes that occurred during the preceding four thousand years all put together.

Perhaps the Mad Hatter had a reason for calling time Him.

Science walks forward on two feet, namely theory and experiment. Sometimes it is one foot which is put forward first, sometimes the other, but continuous progress is only made by the use of both.

There is no likelihood that man can ever tap the power of the atom

The pathetic thing about it is that many scientists are trying to prove the doctrine of evolution, which no science can do.

The chemist in America has in general been content with what I have called a loafer electron theory. He has imagined the electrons sitting around on dry goods boxes at every corner [viz. the cubic atom], ready to shake hands with, or hold on to similar loafer electrons in other atoms.

Just how we fit into the plans of the Great Architect and how much he has assigned us to do we do not know, but if we fail in our assignment it is pretty certain that a part of the job will be left undone.

To me it is unthinkable that a real atheist could be a scientist.
