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)
Life is a series of natural and spontaneous changes. Don't resist them; that only creates sorrow. Let reality be reality. Let things flow naturally forward in whatever way they like.
It is not death that a man should fear, but he should fear never beginning to live.
The truth is rarely pure and never simple.
Beauty is truth, truth beauty,—that is all Ye know on earth, and all ye need to know.
The meaning of life is to find your gift. The purpose of life is to give it away.
The spiritual journey is the unlearning of fear and the acceptance of love.
Man is condemned to be free; because once thrown into the world, he is responsible for everything he does.
In three words I can sum up everything I've learned about life: it goes on.
To die is to be a sleep, to sleep, perchance to dream—ay, there's the rub.
There is no beauty without some strangeness.
The only way to deal with an unfree world is to become so absolutely free that your very existence is an act of rebellion.
The mind is not a vessel to be filled, but a fire to be kindled.
The purpose of life is not to be happy. It is to be useful, to be honorable, to be compassionate, to have it make some difference that you have lived and lived well.
Spirituality is not about being perfect. It's about being whole.
We are all in the gutter, but some of us are looking at the stars.
Life is a dream for the wise, a game for the fool, a comedy for the rich, a tragedy for the poor.
Death is a challenge. It tells us not to waste time... It tells us to tell each other that we love each other.
The meaning of life is whatever you ascribe it to be.
The spiritual life does not remove us from the world but leads us deeper into it.
Man's main task in life is to give birth to himself.
