Contract Quotes (11 quotes)

Experience is the great teacher; unfortunately, experience leaves mental scars, and scar tissue contracts.
From speech 'In the Time of Henry Jacob Bigelow', given to the Boston Surgical Society, Medalist Meeting (6 Jun 1921). Printed in Journal of the Medical Association (1921), 77, 599.

I felt exactly how you would feel if you were getting ready to launch and knew you were sitting on top of two million parts—all built by the lowest bidder on a government contract.
His reply to the question, often asked, “When you were sitting in that capsule listening to the count-down, how did you feel?” From speech announcing his Senate retirement (20 Feb 1997). As recorded in 'A Genuine American Hero Says He'll Retire', Tributes Delivered in Congress: John Glenn (1998) in U.S. Government Printing Office, U.S. Congress: Senate, Vol 105, Issue 34, 52. (A similar reference to “the lowest bidder on a government contract” has also been attributed to Alan Shepard.)

I would beg the wise and learned fathers (of the church) to consider with all diligence the difference which exists between matters of mere opinion and matters of demonstration. ... [I]t is not in the power of professors of the demonstrative sciences to alter their opinions at will, so as to be now of one way of thinking and now of another. ... [D]emonstrated conclusions about things in nature of the heavens, do not admit of being altered with the same ease as opinions to what is permissible or not, under a contract, mortgage, or bill of exchange.
Letter to Cristina di Lorena, Grand Duchess of Tuscany (the mother of his patron Cosmo), 1615. Quoted in Sedley Taylor, 'Galileo and Papal Infallibility' (Dec 1873), in Macmillan's Magazine: November 1873 to April 1874 (1874) Vol 29, 94.

In so far as the mind is stronger than the body, so are the ills contracted by the mind more severe than those contracted by the body.

In structure these little animals were fashioned like a bell, and at the round opening they made such a stir, that the particles in the water thereabout were set in motion thereby. … And though I must have seen quite 20 of these little animals on their long tails alongside one another very gently moving, with outstretcht bodies and straitened-out tails; yet in an instant, as it were, they pulled their bodies and their tails together, and no sooner had they contracted their bodies and tails, than they began to stick their tails out again very leisurely, and stayed thus some time continuing their gentle motion: which sight I found mightily diverting.
[Describing the ciliate Vorticella.]
Letter to the Royal Society, London (25 Dec 1702). In Clifford Dobell (ed.), Anthony van Leewenhoek and his “Little Animals” (1932), 277.

It is said that the composing of the Lilavati was occasioned by the following circumstance. Lilavati was the name of the author’s daughter, concerning whom it appeared, from the qualities of the ascendant at her birth, that she was destined to pass her life unmarried, and to remain without children. The father ascertained a lucky hour for contracting her in marriage, that she might be firmly connected and have children. It is said that when that hour approached, he brought his daughter and his intended son near him. He left the hour cup on the vessel of water and kept in attendance a time-knowing astrologer, in order that when the cup should subside in the water, those two precious jewels should be united. But, as the intended arrangement was not according to destiny, it happened that the girl, from a curiosity natural to children, looked into the cup, to observe the water coming in at the hole, when by chance a pearl separated from her bridal dress, fell into the cup, and, rolling down to the hole, stopped the influx of water. So the astrologer waited in expectation of the promised hour. When the operation of the cup had thus been delayed beyond all moderate time, the father was in consternation, and examining, he found that a small pearl had stopped the course of the water, and that the long-expected hour was passed. In short, the father, thus disappointed, said to his unfortunate daughter, I will write a book of your name, which shall remain to the latest times—for a good name is a second life, and the ground-work of eternal existence.
In Preface to the Persian translation of the Lilavati by Faizi (1587), itself translated into English by Strachey and quoted in John Taylor (trans.) Lilawati, or, A Treatise on Arithmetic and Geometry by Bhascara Acharya (1816), Introduction, 3. [The Lilavati is the 12th century treatise on mathematics by Indian mathematician, Bhaskara Acharya, born 1114.]

The average English author [of mathematical texts] leaves one under the impression that he has made a bargain with his reader to put before him the truth, the greater part of the truth, and nothing but the truth; and that if he has put the facts of his subject into his book, however difficult it may be to unearth them, he has fulfilled his contract with his reader. This is a very much mistaken view, because effective teaching requires a great deal more than a bare recitation of facts, even if these are duly set forth in logical order—as in English books they often are not. The probable difficulties which will occur to the student, the objections which the intelligent student will naturally and necessarily raise to some statement of fact or theory—these things our authors seldom or never notice, and yet a recognition and anticipation of them by the author would be often of priceless value to the student. Again, a touch of humour (strange as the contention may seem) in mathematical works is not only possible with perfect propriety, but very helpful; and I could give instances of this even from the pure mathematics of Salmon and the physics of Clerk Maxwell.
In Perry, Teaching of Mathematics (1902), 59-61.

The earth itself assures us it is a living entity. Deep below surface one can hear its slow pulse, feel its vibrant rhythm. The great breathing mountains expand and contract. The vast sage desert undulates with almost imperceptible tides like the oceans. From the very beginning, throughout all its cataclysmic upthrusts and deep sea submergences, the planet Earth seems to have maintained an ordered rhythm.

The increase of disorder or entropy with time is one example of what is called an arrow of time something that gives a direction to time and distinguishes the past from the future. There are at least three different directions of time. First, there is the thermodynamic arrow of time—the direction of time in which disorder or entropy increases. Second, there is the psychological arrow of time. This is the direction in which we feel time passes—the direction of time in which we remember the past, but not the future. Third, there is the cosmological arrow of time. This is the direction of time in which the universe is expanding rather than contracting.
In 'The Direction of Time', New Scientist (9 Jul 1987), 46.

The owner of the means of production is in a position to purchase the labor power of the worker. By using the means of production, the worker produces new goods which become the property of the capitalist. The essential point about this process is the relation between what the worker produces and what he is paid, both measured in terms of real value. In so far as the labor contract is free what the worker receives is determined not by the real value of the goods he produces, but by his minimum needs and by the capitalists’ requirements for labor power in relation to the number of workers competing for jobs. It is important to understand that even in theory the payment of the worker is not determined by the value of his product.

[A comparison] of the mind of a bigot to the pupil of the eye; the more light you pour on it, the more it contracts.
In The Autocrat of the Breakfast Table (1858), 167. Holmes continued by writing that he was renouncing any claim to being the first to utter that idea, having been shown “that it occurs in a Preface to certain Political Poems of Thomas Moore’s.” He also wrote he was sensitive to charges of plagiarism, but, nevertheless, he asserted that when he uttered it, it was with the belief that it was his own novel idea. But, “It is impossible to tell, in a great many cases, whether a comparison which suddenly suggests itself is a new conception or a recollection.” Moore had written in Corruption and Intolerance (1808) that “The minds of some men, like the pupil of the human eye, contract themselves the more, the stronger light there is shed upon them.”

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
