Conversant Quotes (6 quotes)

…nature seems very conversant with the rules of pure mathematics, as our own mathematicians have formulated them in their studies, out of their own inner consciousness and without drawing to any appreciable extent on their experience of the outer world.
In The Mysterious Universe (1930), 113.

As arithmetic and algebra are sciences of great clearness, certainty, and extent, which are immediately conversant about signs, upon the skilful use whereof they entirely depend, so a little attention to them may possibly help us to judge of the progress of the mind in other sciences, which, though differing in nature, design, and object, may yet agree in the general methods of proof and inquiry.
In Alciphron: or the Minute Philosopher, Dialogue 7, collected in The Works of George Berkeley D.D. (1784), Vol. 1, 621.

He [Sylvester] had one remarkable peculiarity. He seldom remembered theorems, propositions, etc., but had always to deduce them when he wished to use them. In this he was the very antithesis of Cayley, who was thoroughly conversant with everything that had been done in every branch of mathematics.
I remember once submitting to Sylvester some investigations that I had been engaged on, and he immediately denied my first statement, saying that such a proposition had never been heard of, let alone proved. To his astonishment, I showed him a paper of his own in which he had proved the proposition; in fact, I believe the object of his paper had been the very proof which was so strange to him.
As quoted by Florian Cajori, in Teaching and History of Mathematics in the United States (1890), 268.

I have now said enough to show you that it is indispensable for this country to have a scientific education in connexion with manufacturers, if we wish to outstrip the intellectual competition which now, happily for the world, prevails in all departments of industry. As surely as darkness follows the setting of the sun, so surely will England recede as a manufacturing nation, unless her industrial population become much more conversant with science than they are now.
In 'The Study of Abstract Science Essential to the Progress of Industry', Records of the School of Mines (1852) 1, 48.

It is not of the essence of mathematics to be conversant with the ideas of number and quantity. Whether as a general habit of mind it would be desirable to apply symbolic processes to moral argument, is another question.
An Investigation of the Laws of Thought (1854), 12.
Science quotes on:  |  Application (257)  |  Apply (170)  |  Argument (145)  |  Desirability (2)  |  Desirable (33)  |  Essence (85)  |  General (521)  |  Habit (174)  |  Idea (881)  |  Mathematics (1395)  |  Mind (1377)  |  Moral (203)  |  Number (710)  |  Process (439)  |  Quantity (136)  |  Question (649)  |  Symbolic (16)

The invertebrated classes include the most numerous and diversified forms of the Animal Kingdom. At the very beginning of our inquiries into their vital powers and acts we are impressed with their important relations to the maintenance of life and organization on this planet, and their influence in purifying the sea and augmenting and enriching the land—relations of which the physiologist conversant only with the vertebrated animals must have remained ignorant.
In Lecture, delivered at the Royal College of Surgeons, collected in Lecture 24, 'Cephalopoda', Lectures on the Comparative Anatomy and Physiology of the Invertebrate Animals (1843), Vol. 1, 362.

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
