“A period of about twelve years measured the beat of the pendulum.”

—  Henry Adams

A History of the United States of America During the First Administration of James Madison (1890), Vol. II, Ch. VI: Meeting of the Twelfth Congress; 1921 edition, p. 123
Context: A period of about twelve years measured the beat of the pendulum. After the Declaration of Independence, twelve years had been needed to create an efficient Constitution; another twelve years of energy brought a reaction against the government then created; a third period of twelve years was ending in a sweep toward still greater energy; and already a child could calculate the result of a few more such returns.

“The history of human thought recalls the swinging of a pendulum which takes centuries to swing. After a long period of slumber comes a moment of awakening.”

Context: The history of human thought recalls the swinging of a pendulum which takes centuries to swing. After a long period of slumber comes a moment of awakening. Then thought frees herself from the chains with which those interested — rulers, lawyers, clerics — have carefully enwound her.
She shatters the chains. She subjects to severe criticism all that has been taught her, and lays bare the emptiness of the religious political, legal, and social prejudices amid which she has vegetated. She starts research in new paths, enriches our knowledge with new discoveries, creates new sciences.
But the inveterate enemies of thought — the government, the lawgiver, and the priest — soon recover from their defeat. By degrees they gather together their scattered forces, and remodel their faith and their code of laws to adapt them to the new needs.

“Gravitation is not only similar to inertia in its generality, it is also measured by the same number… the mass. The inertial mass is what Newton calls the "quantity of matter": it is a measure for the resistance offered by a body to a force trying to alter its state of motion. It might be called the "passive mass." The gravitational mass, on the other hand, is a measure of the force exerted by the body in attracting other bodies. We might call it the "active" mass. The equality of active and passive, or gravitational and inertial, mass was in Newton's system a most remarkable accidental co-incidence, something like a miracle. Newton himself decidedly felt it as such, and made experiments to verify it, by swinging a pendulum with a hollow bob which could be filled with different materials. The force acting on the pendulum is proportional to its gravitational mass, the inertia to its inertial mass: the period of its swing thus depends on the ratio between these two masses. The fact that the period is always the same therefore proves that the gravitational and inertial masses are equal.”

“When I was a boy, I had a clock with a pendulum that could be lifted off. I found that the clock went very much faster without the pendulum. If the main purpose of a clock is to go, the clock was the better for losing its pendulum. True, it could no longer tell the time, but that did not matter if one could teach oneself to be indifferent to the passage of time. The linguistic philosophy which cares only about language and not about the world, is like the boy who preferred the clock without the pendulum because, although it no longer told the time, it went more easily than before and at a more exhilarating pace.”

“The doctrine of progression… was thus given twelve years ago by Professor Sedgwick”

Charles Lyell (1797–1875) British lawyer and geologist

Source: The Geological Evidences of the Antiquity of Man (1863), Ch.20, p. 395-396
Context: The doctrine of progression... was thus given twelve years ago by Professor Sedgwick, in the preface to his Discourse on the Studies of the University of Cambridge. 'There are traces,' he says, 'among the old deposits of the earth of an organic progression among the successive forms of life. They are to be seen in the absence of mammalia in the older, and their very rare appearance in the newer secondary groups; in the diffusion of warm blooded quadrupeds (frequently of unknown genera) in the older tertiary system, and in their great abundance (and frequently of known genera) in the upper portions of the same series; and lastly, in the recent appearance of Man on the surface of the earth.' 'This historical development,' continues the same author, 'of the forms and functions of organic life during successive epochs, seems to mark a gradual evolution of creative power, manifested by a gradual ascent towards a higher type of being.' 'But the elevation of the fauna of successive periods was not made by transmutation, but by creative additions; and it is by watching these additions that we get some insight into Nature's true historical progress, and learn that there was a time when Cephalopoda were the highest types of animal life, the primates of this world; that Fishes next took the lead, then Reptiles; and that during the secondary period they were anatomically raised far above any forms of the reptile class now living in the world. Mammals were added next, until Nature became what she now is, by the addition of Man.... the generalisation, as laid down by the Woodwardian Professor, still holds good in all essential particulars.

Observations upon the Prophecies of Daniel, and the Apocalypse of St. John (1733)
Context: John therefore baptized two summers, and Christ preached three. The first summer John preached to make himself known, in order to give testimony to Christ. Then, after Christ came to his baptism and was made known to him, he baptized another summer, to make Christ known by his testimony; and Christ also baptized the same summer, to make himself the more known: and by reason of John's testimony there came more to Christ's baptism than to John's. The winter following John was imprisoned; and now his course being at an end, Christ entered upon his proper office of preaching in the cities. In the beginning of his preaching he completed the number of the twelve Apostles, and instructed them all the first year in order to send them abroad. Before the end of this year, his fame by his preaching and miracles was so far spread abroad, that the Jews at the Passover following consulted how to kill him. In the second year of his preaching, it being no longer safe for him to converse openly in Judea, he sent the twelve to preach in all their cities: and in the end of the year they returned to him, and told him all they had done. All the last year the twelve continued with him to be instructed more perfectly, in order to their preaching to all nations after his death. And upon the news of John's death, being afraid of Herod as well as of the Jews, he walked this year more secretly than before; frequenting deserts, and spending the last half of the year in Judea, without the dominions of Herod.

“The history of the twelve-week return to the so-called original conditions of work is soon told. The daily and weekly output rose to a point higher than at any other time and in the whole period "there was no downward trend." At the end of twelve weeks, in period thirteen, the group returned, as had been arranged, to the conditions of period seven with the sole difference that whereas the Company continued to supply coffee or other beverage for the mid-morning lunch, the girls now provided their own food. This arrangement lasted for thirty-one weeks—much longer than any previous change. Whereas in period twelve the group's output had exceeded that of all the other performances, in period thirteen, with rest-pauses and refreshment restored, their output rose once again to even greater heights”
