Nothing in life is to be feared, it is only to be understood.

Life is not easy for any of us, but what of that? We must have perseverance and above all confidence in ourselves. We must believe that we are gifted in something, and that this thing, at whatever cost, must be attained.

One never notices what has been done; one can only see what remains to be done.

We must not forget that when radium was discovered no one knew that it would prove useful in hospitals. The work was one of pure science. And this is a proof that scientific work must not be considered from the point of view of the direct usefulness of it. It must be done for itself, for the beauty of science, and then there is always the chance that a scientific discovery may become like the radium a benefit for humanity.

All my life through, the new sights of nature made me rejoice like a child.

There are sadistic scientists who hurry to hunt down errors instead of establishing the truth.

Nothing in this world is to be feared... only understood.

I was taught that the way of progress is neither swift nor easy.

Nothing in life is to be feared. It is only to be understood.

Life is not easy for any of us, but what of that? We must have perseverance and, above all, confidence in ourselves.

Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less.

You cannot hope to build a better world without improving the individuals. To that end each of us must work for his own improvement, and at the same time share a general responsibility for all humanity, our particular duty being to aid those to whom we think we can be most useful.

One never notices what has been done one can only see what remains to be done.

Be less curious about people and more curious about ideas.

I am among those who think that science has great beauty. A scientist in his laboratory is not only a technician: he is also a child placed before natural phenomena which impress him like a fairy tale.
