One of the chief peculiarities of this treatise is the doctrine that the true electric current, on which the electromagnetic phenomena depend, is not the same thing as the current of conduction, but that the time-variation of the electric displacement must [also] be taken into account.
JAMES CLERK MAXWELLThe 2nd law of thermodynamics has the same degree of truth as the statement that if you throw a tumblerful of water into the sea, you cannot get the same tumblerful of water out again.

In speaking of the Energy of the field, however, I wish to be understood literally. All energy is the same as mechanical energy, whether it exists in the form of motion or in that of elasticity, or in any other form. The energy in electromagnetic phenomena is mechanical energy.
JAMES CLERK MAXWELL -
Faraday is, and must always remain, the father of that enlarged science of electromagnetism.
JAMES CLERK MAXWELL -
In the heavens we discover [stars] by their light, and by their light alone … the sole evidence of the existence of these distant worlds … that each of them is built up of molecules of the same kinds we find on earth.
JAMES CLERK MAXWELL -
But though the professed aim of all scientific work is to unravel the secrets of nature, it has another effect, not less valuable, on the mind of the worker. It leaves him in possession of methods which nothing but scientific work could have led him to invent.
JAMES CLERK MAXWELL -
Mathematicians may flatter themselves that they possess new ideas which mere human language is as yet unable to express. Let them make the effort to express these ideas in appropriate words without the aid of symbols, and if they succeed they will not only lay us laymen under a lasting obligation.
JAMES CLERK MAXWELL -
The experimental investigation by which Ampere established the law of the mechanical action between electric currents is one of the most brilliant achievements in science. The whole, theory and experiment, seems as if it had leaped, full grown and full armed, from the brain of the ‘Newton of Electricity’.
JAMES CLERK MAXWELL -
I have the capacity of being more wicked than any example that man could set me.
JAMES CLERK MAXWELL -
Science appears to us with a very different aspect after we have found out that it is not in lecture rooms only, and by means of the electric light projected on a screen, that we may witness physical phenomena.
JAMES CLERK MAXWELL -
Thoroughly conscious ignorance is the prelude to every real advance in science.
JAMES CLERK MAXWELL -
I think it ought to occupy a prominent place in our investigations, and that we ought to endeavour to construct a mental representation of all the details of its action, and this has been my constant aim in this treatise.
JAMES CLERK MAXWELL -
Very few of us can now place ourselves in the mental condition in which even such philosophers as the great Descartes were involved in the days before Newton had announced the true laws of the motion of bodies.
JAMES CLERK MAXWELL -
In every branch of knowledge the progress is proportional to the amount of facts on which to build, and therefore to the facility of obtaining data.
JAMES CLERK MAXWELL -
It is perfect in form, and unassailable in accuracy, and it is summed up in a formula from which all the phenomena may be deduced, and which must always remain the cardinal formula of electro-dynamics.
JAMES CLERK MAXWELL -
All the mathematical sciences are founded on relations between physical laws and laws of numbers, so that the aim of exact science is to reduce the problems of nature to the determination of quantities by operations with numbers.
JAMES CLERK MAXWELL -
But that we may find illustrations of the highest doctrines of science in games and gymnastics, in travelling by land and by water, in storms of the air and of the sea, and wherever there is matter in motion.
JAMES CLERK MAXWELL -
When I reappear it will be in the dusky ring, which is something like the state of the air supposing the siege of Sebastopol conducted from a forest of guns 100 miles one way, and 30,000 miles the other, and the shot never to stop, but go spinning away round a circle, radius 170,000 miles.
JAMES CLERK MAXWELL -
Mathematicians may flatter themselves that they possess new ideas which mere human language is as yet unable to express.
JAMES CLERK MAXWELL -
Such indeed is the respect paid to science, that the most absurd opinions may become current, provided they are expressed in language, the sound of which recals [sic] some well-known scientific phrase.
JAMES CLERK MAXWELL -
The experimental verification of the mathematical results therefore is no evidence for or against the peculiar doctrines of this theory.
JAMES CLERK MAXWELL -
The mathematical difficulties of the theory of rotation arise chiefly from the want of geometrical illustrations and sensible images, by which we might fix the results of analysis in our minds.
JAMES CLERK MAXWELL -
What’s the go of that? What’s the particular go of that?
JAMES CLERK MAXWELL -
The University of Cambridge, in accordance with that law of its evolution, by which, while maintaining the strictest continuity between the successive phases of its history, it adapts itself with more or less promptness to the requirements of the times, has lately instituted a course of Experimental Physics.
JAMES CLERK MAXWELL -
The only laws of matter are those that our minds must fabricate and the only laws of mind are fabricated for it by matter.
JAMES CLERK MAXWELL -
Ampere was the Newton of Electricity.
JAMES CLERK MAXWELL -
But I should be very sorry if an interpretation founded on a most conjectural scientific hypothesis were to get fastened to the text in Genesis…
JAMES CLERK MAXWELL -
Heat may be generated and destroyed by certain processes, and this shows that heat is not a substance.
