The artificial products do not have any molecular dissymmetry; and I could not indicate the existence of a more profound separation between the products born under the influence of life and all the others.
Interpretation
This quote highlights the fundamental difference between natural and artificial products at a molecular level.
Louis Pasteur emphasizes that artificial products lack the molecular asymmetry that characterizes products of life. He suggests that there is a profound distinction between naturally occurring substances and those created artificially, implying that life has a unique influence that cannot be replicated by man-made processes.
In practice
In a scientific presentation discussing the differences between synthetic and natural substances.
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. Sédillot) 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.
Almost any questions can be answered,cheaply, quickly and finally, by a test campaign. And that's he way to answer them - not by arguments around a table
The cloning of humans is on most of the lists of things to worry about from Science, along with behaviour control, genetic engineering, transplanted heads, computer poetry and the unrestrained growth of plastic flowers.
Carbon has this genius of making a chemically stable, two-dimensional, one-atom-thick membrane in a three-dimensional world. And that, I believe, is going to be very important in the future of chemistry and technology in general.
When I find myself in the company of scientists, I feel like a shabby curate who has strayed by mistake into a room full of dukes.
A lot of the things you see in science fiction revolve around black holes because black holes are strong enough to rip the fabric of space and time.
The notion of superhumans is using bioengineering and artificial intelligence to upgrade human abilities. If they use the power to change themselves, to change their own minds, their own desires, then we have no idea what they will want to do.
