The mechanical theory of heat, and the indestructibility of motion, the conservation of energy, the modification of species by the action of environment, physiological psychology the anthropological view of history religion and legislation the laws of development of thought in short the whole mechanical conception of the world and all the elements of a synthetic philosophy a philosophy which embraces all physical chemical living and social phenomena were already outlined and partly formulated in the preceding century but owing to the reaction which set in, these discoveries were kept in the background during a full half-century, men of science suppressed them, or else declared them unscientific, under the pretext of studying facts and gathering scientific material, even such exacting measurements as the determination of the mechanical power necessary for obtaining a given amount of heat.

The determinations by Sagan and Joule of the mechanical equivalent of heat were set aside by the scientists, The English Royal Society even declined to publish the results of Jules' investigations into this subject on the ground that they were unscientific, and the excellent work of Grove upon the unity of physical forces, written in 1843, remained up to 1856 in complete obscurity.

Only in consulting the history of the exact sciences can one fully understand the forces of reaction which then swept over Europe.

The curtain was suddenly rent at the end of the fifties, when that liberal intellectual movement began in Western Europe, which led in Russia to the abolition of serfdom and opposed Schilling and Hegel and philosophy, while in life it called forth the bold negation of intellectual slavery in submission to the habit and authority which is known under the name of nihilism.

Let us then dwell a little longer upon the results obtained in these years, that we may better appreciate the next attempt at a synthetic philosophy, which was made by Herbert Spencer.

Grove, Clausius, Helmholtz, Joule, and a whole group of physicists and astronomers, as also Kirchhoff, who discovered the spectroscopic analysis and gave us the means of determining the composition of the most distant stars, these in rapid succession at the end of the 50s proved the unity of nature, throughout the inorganic world.

To talk of certain mysterious, imponderable fluids, calorific, magnetic, electrical, at once became impossible.

It was shown that the mechanical motion of molecules, which takes place in the waves of the sea or in the vibrations of a bell or a tuning fork, was adequate to the explanation of all the phenomena of heat, light, electricity, and magnetism, that we can measure them and weigh their energy.

The curtain was suddenly rent at the end of the fifties when that liberal intellectual movement began in Western Europe, which led in Russia to the abolition of serfdom and opposed Schilling and Hegel in philosophy, while in life it called forth the bold negation of intellectual slavery and submission to the habit and authority which is known under the name of nihilism.

Without entering here into detail, it is sufficient to say that the above-mentioned Seguin and Augustin Thierry, the historian who laid the foundations for the study of the folk-mode regime and of federalism, were Saint-Simonists, that Darwin's fellow-worker, A.R. Wallace, was in his younger days an enthusiastic follower of Robert Owen, that Auguste Comte was a Saint-Simonist, that Ricardo and Bentham were Owenists, and that the materialist, Charles Wolt and George Lewis, as well as Grove, Mill, Spencer, and many others, had lived under the influence of the radical socialist movement of the thirties and forties.

It was to this very influence that they owed their scientific boldness.

The simultaneous appearance of the works of Grove, Joule, Berthelot, and Helmholtz, of Darwin, Claude Bernard, Moléshotte, and Würth, of Lyle, Banne, Mill, and Björnoff, all in the brief space of five or six years, 1856 to 1862, radically changed the most fundamental views of science.

But you realize now this caloric fluid can be produced from nowhere because there was no caloric fluid before, but slamming the two cars produces this extra heat.

So, that indicates that perhaps there's a relation between mechanical energy and heat energy, that when mechanical energy disappears, So, how do you do the conversion ratio? How many calories can you get if you sacrifice one joule of mechanical energy? So, Joule did the experiment, not with cars.

I mean, he didn't have cars at that time, so if he did, he would have probably done it with cars.

He had this gadget with him, which was a little shaft with some paddles and a pulley on the top, and you let the weight go down.

That Auguste Comte was a St. Simonist.

and ricardo and bentham were owenists and that the materialists charles volt and george lewis as well as grove mill spencer and many others had lived under the influence of the radical socialist movement of the thirties and forties it was to this very influence that they owed their scientific boldness The simultaneous appearance of the works of Grove, Joule, Berthollet, and Helmholtz, of Darwin, Claude Bernard, Moleschott, and Wirt, of Lyle, Bann, Mill, and Bjurnhoff, all in the brief space of five or six years, 1856 to 1862, radically change the most fundamental views of science.

science suddenly started upon a new path entirely new fields of investigations were opened with amazing rapidity the science of life biology of human institutions anthropology of reason will and emotions psychology of the history of rights and religions and so on grew up under the very eyes staggering the mind with the boldness of their generalisations and the audacity of their deductions what in the preceding century was only an ingenious guess now came forth proved by the scales and the microscope verified by thousands of applications The very manner of writing changed, and science returned to the clearness, the precision, and the beauty of exposition which are peculiar to the inductive method and which characterized those of the thinkers of the eighteenth century who had broken away from metaphysics.

We'll be continued.

See, for a very long time, physicists treated energy conservation as just a brute empirical fact.

Joule and Mayer observed it, and everyone just accepted it because the math always worked.

But they didn't know why.

Exactly.
