André-Marie Ampère
One of the founders of the science of classical electromagnetism, which he referred to as 'electrodynamics'.
Most quoted
"The most general law of electrodynamic action is that two elements of current attract or repel each other in the inverse ratio of the square of their distance, and in the direct ratio of the product of their lengths and of the sines of the angles which they make with the line joining them."
— from Théorie mathématique des phénomènes électrodynamiques, uniquement déduite de l'expérience, 1826
"The force between two current elements is proportional to the product of their lengths, to the product of the currents they carry, and to the sine of the angle between their directions, and inversely proportional to the square of the distance between them."
— from Mémoire sur la théorie mathématique des phénomènes électrodynamiques, uniquement déduite de l'expérience, 1826
"The facts are the only things that are certain in science, and the only way to arrive at truth is to observe them carefully and to deduce from them, by means of rigorous reasoning, the laws that govern them."
— from Essai sur la philosophie des sciences, ou Exposition analytique d'une classification naturelle de toutes les connaissances humaines
All quotes by André-Marie Ampère (369)
The most incomprehensible thing about the world is that it is comprehensible.
The important thing is not to stop questioning.
I have no special talent. I am only passionately curious.
The only thing that interferes with my learning is my education.
The value of a man should be seen in what he gives and not in what he is able to receive.
Try not to become a man of success, but rather try to become a man of value.
The most beautiful experience we can have is the mysterious. It is the fundamental emotion that stands at the cradle of true art and true science.
A human being is a part of a whole, called by us universe, a part limited in time and space.
The only way to escape the corruptible effect of praise is to go on working.
The more I study, the more I am convinced that the world is governed by laws that are not of our making.
The true sign of intelligence is not knowledge but imagination.
The only thing that is constant is change.
The greatest discovery of all time is that a person can change his future by merely changing his attitude.
The mind is everything. What you think you become.
The best way to predict the future is to create it.
The only true wisdom is in knowing you know nothing.
The unexamined life is not worth living.
The only thing we have to fear is fear itself.
The journey of a thousand miles begins with a single step.
What we achieve inwardly will change outer reality.
