Never will the doctrine of spontaneous generation recover from the mortal blow struck by this simple experiment.
Interpretation
Pasteur's experiment refuted the belief that life could arise spontaneously from non-living matter.
This quote highlights the significance of Louis Pasteur's experiments in disproving the long-held notion of spontaneous generation, where it was believed that living organisms could emerge from inanimate objects. Pasteur's findings laid the groundwork for modern microbiology and dramatically shifted our understanding of life's origins, emphasizing the importance of empirical evidence in scientific inquiry.
In practice
In a science class discussing the fundamentals of microbiology, this quote can illustrate the importance of Pasteur's work.
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.
I love science fiction. There are ways in which this community kept me and my partner alive through some very, very bad years, and I will always acknowledge that.
Perhaps one day earthquakes, hurricanes and financial crashes will all be predictable. But we don't have to wait until then for seismology, meteorology and economics to become sciences; they already are.
It is a curious historical fact that modern quantum mechanics began with two quite different mathematical formulations: the differential equation of Schroedinger and the matrix algebra of Heisenberg. The two apparently dissimilar approaches were proved to be mathematically equivalent.
Theory is the essence of facts. Without theory scientific knowledge would be only worthy of the madhouse.
The sheer quantity of brain power that hurled itself voluntarily and quixotically into the search for new baseball knowledge was either exhilarating or depressing, depending on how you felt about baseball. The same intellectual resources might have cured the common cold, or put a man on Pluto.
The word 'universe' is obviously not intended to have a plural, but science has evolved in such a way that we need a plural noun for something similar to what we ordinarily call our universe.
