Heat may be generated and destroyed by certain processes, and this shows that heat is not a substance.
JAMES CLERK MAXWELLBut 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.

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 -
Thus number may be said to rule the whole world of quantity, and the four rules of arithmetic may be regarded as the complete equipment of the mathematician.
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 -
I have been battering away at Saturn, returning to the charge every now and then. I have effected several breaches in the solid ring, and now I am splash into the fluid one, amid a clash of symbols truly astounding.
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 -
The equations at which we arrive must be such that a person of any nation, by substituting the numerical values of the quantities as measured by his own national units, would obtain a true result.
JAMES CLERK MAXWELL -
Gases are distinguished from other forms of matter, not only by their power of indefinite expansion so as to fill any vessel, however large, and by the great effect heat has in dilating them, but by the uniformity and simplicity of the laws which regulate these changes.
JAMES CLERK MAXWELL -
Faraday is, and must always remain, the father of that enlarged science of electromagnetism.
JAMES CLERK MAXWELL -
The popularisation of scientific doctrines is producing as great an alteration in the mental state of society as the material applications of science are effecting in its outward life.
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 -
The true Logic for this world is the Calculus of Probabilities, which takes account of the magnitude of the probability.
JAMES CLERK MAXWELL -
Thoroughly conscious ignorance is the prelude to every real advance in science.
JAMES CLERK MAXWELL -
Wherein they fancy intersperses Long avenues of universes, While Klein and Clifford fill the void With one finite, unbounded homoloid, And think the Infinite is now at last destroyed.
JAMES CLERK MAXWELL -
But, we venture to say, they will find themselves very much enlightened during the process, and will even be doubtful whether the ideas as expressed in symbols had ever quite found their way out of the equations into their minds.
JAMES CLERK MAXWELL -
Ampere was the Newton of Electricity.
JAMES CLERK MAXWELL -
At quite uncertain times and places, The atoms left their heavenly path, And by fortuitous embraces, Engendered all that being hath. And though they seem to cling together, And form ‘associations’ here, Yet, soon or late, they burst their tether, And through the depths of space career.
JAMES CLERK MAXWELL -
All the mathematical sciences are founded on relations between physical laws and laws of numbers.
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 of great advantage to the student of any subject to read the original memoirs on that subject, for science is always most completely assimilated when it is in the nascent state.
JAMES CLERK MAXWELL -
The 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.
JAMES CLERK MAXWELL -
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 MAXWELL -
I have the capacity of being more wicked than any example that man could set me.
JAMES CLERK MAXWELL -
The student who uses home made apparatus, which is always going wrong, often learns more than one who has the use of carefully adjusted instruments, to which he is apt to trust and which he dares not take to pieces.
JAMES CLERK MAXWELL -
The rate of change of scientific hypothesis is naturally much more rapid than that of Biblical interpretations, so that if an interpretation is founded on such an hypothesis, it may help to keep the hypothesis above ground long after it ought to be buried and forgotten.
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 -
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.
