Changing Quotes (7 quotes)

I like to tell students that the jobs I took [at NASA] after my Ph.D. were not in existence only a few years before. New opportunities can open up for you in this ever changing field.
From interview, 'Happy 90th Birthday, Nancy', on NASA website (30 May 2017).

In pure mathematics we have a great structure of logically perfect deductions which constitutes an integral part of that great and enduring human heritage which is and should be largely independent of the perhaps temporary existence of any particular geographical location at any particular time. … The enduring value of mathematics, like that of the other sciences and arts, far transcends the daily flux of a changing world. In fact, the apparent stability of mathematics may well be one of the reasons for its attractiveness and for the respect accorded it.
In Fundamentals of Mathematics (1941), 463.

In the beginning of the year 1800 the illustrious professor conceived the idea of forming a long column by piling up, in succession, a disc of copper, a disc of zinc, and a disc of wet cloth, with scrupulous attention to not changing this order. What could be expected beforehand from such a combination? Well, I do not hesitate to say, this apparently inert mass, this bizarre assembly, this pile of so many couples of unequal metals separated by a little liquid is, in the singularity of effect, the most marvellous instrument which men have yet invented, the telescope and the steam engine not excepted.
In François Arago, 'Bloge for Volta' (1831), Oeuvres Completes de François Arago (1854), Vol. 1, 219-20.

Knowledge of the laws of nature offers humankind the only chance of survival in a changing environment. … The search for knowledge gives expression to a basic curiosity which appears to be the salient defining characteristic of human beings.
From opening paragraph of Preface, Quasars, Redshifts and Controversies (1987).

No problem can be solved until it is reduced to some simple form. The changing of a vague difficulty into a specific, concrete form is a very essential element in thinking.
Seen, for example, in The Grain and Feed Review (1931), 21, 34.
Science quotes on:  |  Concrete (32)  |  Difficulty (146)  |  Element (162)  |  Essential (117)  |  Form (314)  |  Problem (497)  |  Reduction (41)  |  Simple (178)  |  Solution (216)  |  Specific (37)  |  Thinking (231)  |  Vague (26)

Progress should mean that we are always changing the world to fit the vision, instead we are always changing the vision.
From Orthodoxy (1908, 1909), 195.
Science quotes on:  |  Fit (48)  |  Instead (19)  |  Mean (101)  |  Progress (368)  |  Vision (94)  |  World (898)

Some of the scientists, I believe, haven’t they been changing their opinion a little bit on global warming? There’s a lot of differing opinions and before we react I think it’s best to have the full accounting, full understanding of what’s taking place.
Presidential Debate (2000). In Historic Documents of 2000 (2001), 823.
Science quotes on:  |  Belief (504)  |  Best (173)  |  Differing (2)  |  Full (63)  |  Global Warming (26)  |  Opinion (176)  |  React (7)  |  Scientist (522)  |  Think (347)  |  Understanding (325)


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
