Chance favours the trained mind.

My present and most fixed opinion regarding the nature of alcoholic fermentation is this: The chemical act of fermentation is essentially a phenomenon correlative with a vital act, beginning and ending with the latter. I believe that there is never any alcoholic fermentation without their being simultaneously the organization, development, multiplication of the globules, or the pursued, continued life of globules which are already formed.

If science has no country, the scientist should have one, and ascribe to it the influence which his works may have in this world.

If you suppress laboratories, physical science will be stricken with barrenness and death.

Chance favours a prepared mind.

Science knows no country, because knowledge belongs to humanity, and is the torch which illuminates the world. Science is the highest personification of the nation because that nation will remain the first which carries the furthest the works of thought and intelligence.

Posterity will one day laugh at the foolishness of modern materialistic philosophers.
