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 action of a current on another current is direct, without the intervention of any medium.
The laws of electrodynamics are as certain as those of mechanics.
The theory of electrodynamics is a new branch of physics.
The phenomena of terrestrial magnetism are due to electric currents circulating in the interior of the Earth.
The existence of these currents is a necessary consequence of the laws of electrodynamics.
The forces which act between two elements of current are not central forces.
The direction of the force is not along the line joining the two elements of current.
This is a fundamental difference between electrodynamic forces and gravitational forces.
The principle of the conservation of energy is a fundamental law of nature.
The universe is governed by mathematical laws.
The human mind is capable of comprehending the most complex phenomena.
The progress of science is a continuous process of discovery and refinement.
The ultimate goal of science is to understand the universe.
The true scientist is one who is open to new ideas and willing to challenge established beliefs.
The pursuit of knowledge is an endless journey.
The laws of nature are universal and immutable.
The scientific method is the most reliable way to acquire knowledge.
The role of the scientist is to observe, experiment, and theorize.
The greatest discoveries are often made by those who dare to think differently.
The future of humanity depends on the progress of science.
