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)
If you want to live a happy life, tie it to a goal, not to people or things.
Strive not to be a success, but rather to be of value.
Electricity and magnetism are but two aspects of the same force.
The soul finds its noblest expression in the pursuit of truth.
In the silence of the laboratory, nature reveals her secrets.
Loss teaches us the fragility of human bonds.
True genius lies in simplicity of explanation.
Currents flow as do the rivers of destiny.
The guillotine's shadow lingers, but science illuminates the path forward.
Ampère's law: the force between wires is mutual and mathematical.
Happiness is found in the harmony of mind and matter.
Revolution devours its children, yet knowledge endures.
A witty spark: magnets attract, but fools repel.
From chaos of elements to order of laws.
Life's circuit is complete only through love and discovery.
The helix of life twists through joy and sorrow.
Electrodynamics: where invisible forces dance.
Philosophy without experiment is but a dream.
In solitude, the mind forges unbreakable chains of thought.
Politics is the current that powers or shorts society's circuit.
