I give them experiments and they respond with speeches.
Interpretation
Pasteur highlights the contrast between action (experimentation) and mere talk (speeches).
In this quote, Louis Pasteur emphasizes the importance of practical experimentation over theoretical discussion. He suggests that while some may only engage in rhetoric, true progress and understanding come from hands-on experimentation and direct engagement with the world.
In practice
In a scientific conference discussing the importance of practical research, this quote can emphasize the need for hands-on experiments.
To demonstrate experimentally that a microscopic organism actually is the cause of a disease and the agent of contagion, I know no other way, in the present state of Science, than to subject the microbe (the new and happy term introduced by M. SΓ©dillot) to the method of cultivation out of the body.
The universe is an asymmetrical entity. I am inclined to believe that life as it is manifested to us must be a function of the asymmetry of the universe or of the consequence of this fact. The universe is asymmetrical; for if one placed the entire set of bodies that compose the solar system, each moving in its own way, before a mirror, the image shown would not be superimposable on the reality.
These are the living springs of great thoughts and great actions. Everything grows clear in the reflections from the Infinite.
Without theory, practice is but routine born of habit. Theory alone can bring forth and develop the spirit of invention. ... [Do not] share the opinion of those narrow minds who disdain everything in science which has not an immediate application. ... A theoretical discovery has but the merit of its existence: it awakens hope, and that is all. But let it be cultivated, let it grow, and you will see what it will become.
These three things-work, will, success-fill human existences. Will opens the door to success, both brilliant and happy. Work passes these doors, and at the end of the journey success comes in to crown one's efforts.
Chance favors those who are prepared.
New knowledge has led to the recognition in the theory of evolution of more than a hypothesis. It is indeed remarkable that this theory has been progressively accepted by researchers, following a series of discoveries in various fields of knowledge. The convergence, neither sought nor fabricated, of the results of work that was conducted independently is in itself a significant argument in favor of this theory.
The best scientist is open to experience and begins with romance - the idea that anything is possible.
It is an art of no little importance to administer medicines properly: but, it is an art of much greater and more difficult acquisition to know when to suspend or altogether to omit them.
We can allow satellites, planets, suns, universe, nay whole systems of universes, to be governed by laws, but the smallest insect, we wish to be created at once by special act.
While NASA talks about 'Are we alone?' as a number one question, they are putting zero money into searching for intelligent life. There's a big disconnect there.
The Hellish and dismal cloud of...Coal...perpetually imminent over (London) ...that her inhabitants breathe nothing but impure and thick mist...corrupting the lungs and disordering the entire habit of their bodies; so the Catarrhs,...Cough, and Consumption, range more in this one City, than in the whole Earth besides.
