In the realm of scientific observation, luck is granted only to those who are prepared.
Without theory, practice is but routine born of habit. Theory alone can bring forth and develop the spirit of inventions.
One must not assume that an understanding of science is present in those who borrow the language.
How do you know that the incessant progress of science will not compel scientists to consider that life has existed during eternity, and not matter?
What did you do today to receive your instruction?
I am on the edge of mysteries and the veil is getting thinner and thinner.
These are the living springs of great thoughts and great actions. Everything grows clear in the reflections from the Infinite.
Science brings men nearer to God.
Blessed is he who carries within himself a God, an ideal, and who obeys it: ideal of art, ideal of science, ideal of the gospel virtues, therein lie the springs of great thoughts and great actions; they all reflect light from the Infinite.
Time is the best appraiser of scientific work, and I am aware that an industrial discovery rarely produces all its fruit in the hands of its first inventor.
To know how to wonder and question is the first step of the mind toward discovery.
Do not put forward anything that you cannot prove by experimentation.
If science has no country, the scientist should have one, and ascribe to it the influence which his works may have in this world.
The only thing that can bring joy is work.
You bring me the deepest joy that can be felt by a man whose invincible belief is that Science and Peace will triumph over Ignorance and War, that nations will unite, not to destroy, but to build, and that the future will belong to those who will have done most for suffering humanity.
Worship the spirit of criticism. If reduced to itself it is not an awakener of ideas or a stimulant to great things, but, without it, everything is fallible; it always has the last word.
Change only favours minds that are diligently looking and preparing for discovery.
Blessed is he who carries within himself a God, an ideal, and obeys it.
Oh my goodness the mystery that has prompted my objective. My quality lies exclusively in my tirelessness.
If you suppress laboratories, physical science will be stricken with barrenness and death.
