Thoroughly conscious ignorance is the prelude to every real advance in science.

James Clerk Maxwell

But I think that the results which each man arrives at in his attempts to harmonize his science with his Christianity ought not to be regarded as having any significance except to the man himself, and to him only for a time, and should not receive the stamp of a society.
JAMES CLERK MAXWELL

Attempt Christianity Harmonize Receive Result Science Stamp Think
Every existence above a certain rank has its singular points; the higher the rank the more of them. At these points, influences whose physical magnitude is too small to be taken account of by a finite being may produce results of the greatest importance.
JAMES CLERK MAXWELL

Above Certain Every Existence Influence Magnitude More Physical Point Rank Singular Them These
In fact, whenever energy is transmitted from one body to another in time, there must be a medium or substance in which the energy exists after it leaves one body and before it reaches the other … and if we admit this medium as an hypothesis.
JAMES CLERK MAXWELL

Another Body Energy Exist Leave Medium Must One Substance Time Transmitted
Faraday is, and must always remain, the father of that enlarged science of electromagnetism.
JAMES CLERK MAXWELL

Always Electromagnetism Enlarge Faraday Father Must Remain Science
The chief philosophical value of physics is that it gives the mind something distinct to lay hold of, which, if you don’t, Nature at once tells you you are wrong.
JAMES CLERK MAXWELL

Chief Distinct Give Hold Lay Mind Nature Philosopher Something Tell Wrong
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 Place Quite Time Uncertain
The mind of man has perplexed itself with many hard questions. Is space infinite, and in what sense? Is the material world infinite in extent, and are all places within that extent equally full of matter? Do atoms exist or is matter infinitely divisible?
JAMES CLERK MAXWELL

Extent Hard Infinite Itself Man Many Material Mind Place Prep; Exed Question Space World
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

Arrive Eualation Measure Nation National Numerical Own Person Quantities Substuiting Such Value
Science is incompetent to reason upon the creation of matter itself out of nothing. We have reached the utmost limit of our thinking faculties when we have admitted that because matter cannot be eternal and self-existent it must have been created.
JAMES CLERK MAXWELL

Creation Incomplete Itself Matter Nothing Reason Science Upon
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

Law Matter Mind Must Fabricate Only
We can scarcely avoid the inference that light consists in the transverse undulations of the same medium which is the cause of electric and magnetic phenomena.
JAMES CLERK MAXWELL

Cause Consist Electric Light Magnetic Medium Phenomena Reference Same Scarcely Void
Gin a body meet a body Flyin’ through the air, Gin a body hit a body, Will it fly? and where?

All the mathematical sciences are founded on relations between physical laws and laws of numbers.
JAMES CLERK MAXWELL

All Between Found Law Mathematically Number Physical Relation Science
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

Ampere was the Newton of Electricity.
JAMES CLERK MAXWELL

Ampere Electricity Newton
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

Energy Field Files However Literally Speak Understood
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

Current Expressed Indeed Language Opinion Phrase Respect Scientific Such
The experimental verification of the mathematical results therefore is no evidence for or against the peculiar doctrines of this theory.
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

Francis Galton, whose mission it seems to be to ride other men’s hobbies to death, has invented the felicitous expression ‘structureless germs’.

We define thermodynamics … as the investigation of the dynamical and thermal properties of bodies, deduced entirely from the first and second law of thermodynamics, without speculation as to the molecular constitution.
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

Chiefly Difficulties Fix Geometric Illustration Image Longer Mathematical Regard Result Rotation Sensible Theory
I have also a paper afloat, with an electromagnetic theory of light, which, till I am convinced to the contrary, I hold to be great guns.

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.

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.

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

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.
