See with what force yon river's crystal stream Resists the weight of many a massy beam. To sink the wood the more we vainly toil, The higher it rebounds, with swift recoil. Yet that the beam would of itself ascend No man will rashly venture to contend. Thus too the flame has weight, though highly rare, Nor mounts but when compelled by heavier air.

And many kinds of creatures must have died, Unable to plant out new sprouts of life. For whatever you see that lives and breathes and thrives Has been, from the very beginning, guarded, saved By it's trickery for its swiftness or brute strength. And many have been entrusted to our care, Commended by their usefulness to us. For instance, strength supports a savage lion; Foxes rely on their cunning; deer their flight.

Hope deceives more men than cunning does.

Herrmann Pidoux and Armand Trousseau stated 'Disease exists within us, because of us, and through us', Pasteur did not entirely disagree, 'This is true for certain diseases', he wrote cautiously, only to add immediately: 'I do not think that it is true for all of them'.

In that memorable year, 1822: Oersted, a Danish physicist, held in his hands a piece of copper wire, joined by its extremities to the two poles of a Volta pile. On his table was a magnetized needle on its pivot, and he suddenly saw (by chance you will say, but chance only favours the mind which is prepared) the needle move and take up a position quite different from the one assigned to it by terrestrial magnetism. A wire carrying an electric current deviates a magnetized needle from its position. That, gentlemen, was the birth of the modern telegraph.

You bring me the deepest joy that can be felt by a man whose invincible belief is that Science and Peace will triumph over Ignorance and War, that nations will unite, not to destroy, but to build, and that the future will belong to those who will have done most for suffering humanity.

The test of interesting people is that subject matter doesn't matter.

Mathematical study and research are very suggestive of mountaineering. Whymper made several efforts before he climbed the Matterhorn in the 1860's and even then it cost the life of four of his party. Now, however, any tourist can be hauled up for a small cost, and perhaps does not appreciate the difficulty of the original ascent. So in mathematics, it may be found hard to realise the great initial difficulty of making a little step which now seems so natural and obvious, and it may not be surprising if such a step has been found and lost again.

The world has arisen in some way or another. How it originated is the great question, and Darwin's theory, like all other attempts, to explain the origin of life, is thus far merely conjectural. I believe he has not even made the best conjecture possible in the present state of our knowledge.

It is better to have a few forms well known than to teach a little about many hundred species. Better a dozen specimens thoroughly studied as the result of the first year's work, than to have two thousand dollars' worth of shells and corals bought from a curiosity-shop. The dozen animals would be your own.

A laboratory of natural history is a sanctuary where nothing profane should be tolerated. I feel less agony at improprieties in churches than in a scientific laboratory.

I now never make the preparations for penetrating into some small province of nature hitherto undiscovered without breathing a prayer to the Being who hides His secrets from me only to allure me graciously on to the unfolding of them.

During its development the animal passes through all stages of the animal kingdom. The foetus is a representation of all animal classes in time.

Certainly science has moved forward. But when science progresses, it often opens vaster mysteries to our gaze. Moreover, science frequently discovers that it must abandon or modify what it once believed. Sometimes it ends by accepting what it has previously scorned.

The vortex theory [of the atom] is only a dream. Itself unproven, it can prove nothing, and any speculations founded upon it are mere dreams about dreams.

Simplification of modes of proof is not merely an indication of advance in our knowledge of a subject, but is also the surest guarantee of readiness for farther progress.

What opposite discoveries we have seen! (Signs of true genius, and of empty pockets.) One makes new noses, one a guillotine, One breaks your bones, one sets them in their sockets; But vaccination certainly has been A kind antithesis to Congreve's rockets.

Bread has been made (indifferent) from potatoes; And galvanism has set some corpses grinning, But has not answer'd like the apparatus Of the Humane Society's beginning, By which men are unsuffocated gratis: What wondrous new machines have late been spinning.

Knowledge is not happiness, and science But an exchange of ignorance for that Which is another kind of ignorance.

When Newton saw an apple fall, he found In that slight startle from his contemplation- 'Tis said (for I'll not answer above ground For any sage's creed or calculation)- A mode of proving that the earth turn'd round In a most natural whirl, called 'gravitation'; And this is the sole mortal who could grapple, Since Adam, with a fall, or with an apple.

It is told of Faraday that he refused to be called a physicist; he very much disliked the new name as being too special and particular and insisted on the old one, philosopher, in all its spacious generality: we may suppose that this was his way of saying that he had not over-ridden the limiting conditions of class only to submit to the limitation of a profession.

[Instead of collecting stamps, he collected dictionaries and encyclopaedias:] Because you can learn more from them.

The fact that it's science fiction gives you the license to do anything you want to do.

In science, probably ninety-nine percent of the knowable has to be discovered. We know only a few streaks about astronomy. We are only beginning to imagine the force and composition of the atom. Physics has not yet found any indivisible matter, or psychology a sensible soul.

The body of science is not, as it is sometimes thought, a huge coherent mass of facts, neatly arranged in sequence, each one attached to the next by a logical string. In truth, whenever we discover a new fact it involves the elimination of old ones. We are always, as it turns out, fundamentally in error.
