Louis Pasteur

Science progresses through the accumulation of facts, and the interpretation of those facts.

Where observation is concerned, chance favors only the prepared mind.

The germ is nothing, the terrain is everything.

The scientific method is the only path to truth.

I have been for forty years a professor, and I have never ceased to learn.

The greatest victory is that over oneself.

The future belongs to those who believe in the beauty of their dreams.

There is no greater joy than that of discovery.

Science is the soul of the prosperity of nations and the living source of all progress.

The universe is a vast laboratory, and we are its humble experimenters.

The power of observation is not given to all, but it can be cultivated.

The greatest obstacle to discovery is not ignorance, but the illusion of knowledge.

Every day brings new discoveries, and every discovery opens new horizons.

The scientific spirit is above all a spirit of humility.

The scientist has a duty to be skeptical, but also to be open-minded.

The most important thing is to never stop questioning.

The true scientist is a dreamer who experiments.

The greatest discoveries are often made by accident, but only by those who are prepared to see them.

The more I learn, the more I realize how much I don't know.

The only way to do great work is to love what you do.
