Dynamics Quotes (6 quotes)

Chemical biodynamics, involving as it does, the fusion of many scientific disciplines, … [played a role] in the elucidation of the carbon cycle. It can be expected to take an increasingly important place in the understanding of the dynamics of living organisms on a molecular level.
In Nobel Lecture (11 Dec 1961), 'The Path of Carbon in Photosynthesis', Nobel Lectures: Chemistry 1942-1962 (1964).
Science quotes on:  |  Carbon Cycle (5)  |  Discipline (42)  |  Elucidation (6)  |  Expect (33)  |  Fusion (11)  |  Important (135)  |  Increasingly (3)  |  Molecule (127)  |  Organism (144)  |  Role (36)  |  Scientific (181)  |  Understanding (322)

The equations of dynamics completely express the laws of the historical method as applied to matter, but the application of these equations implies a perfect knowledge of all the data. But the smallest portion of matter which we can subject to experiment consists of millions of molecules, not one of which ever becomes individually sensible to us. We cannot, therefore, ascertain the actual motion of anyone of these molecules; so that we are obliged to abandon the strict historical method, and to adopt the statistical method of dealing with large groups of molecules … Thus molecular science teaches us that our experiments can never give us anything more than statistical information, and that no law derived from them can pretend to absolute precision. But when we pass from the contemplation of our experiments to that of the molecules themselves, we leave a world of chance and change, and enter a region where everything is certain and immutable.
'Molecules' (1873). In W. D. Niven (ed.), The Scientific Papers of James Clerk Maxwell (1890), Vol. 2, 374.

The mechanical speculations of the ancients, particularly of the Greeks, related wholly to statics. Dynamics was founded by Galileo.
In The Science of Mechanics (1893), 128.
Science quotes on:  |  Ancient (71)  |  Founded (11)  |  Galileo Galilei (105)  |  Greek (46)  |  Mechanics (44)  |  Speculation (77)  |  Statics (4)

The mind can quickly scan not only the past, but also the projected future consequences of a choice. Its dynamics transcend the time and space of brain physiology.
From interview collected in Pamela Weintraub (ed.), The Omni Interviews (1984), 187.
Science quotes on:  |  Brain (184)  |  Choice (72)  |  Consequence (81)  |  Future (256)  |  Mind (576)  |  Past (127)  |  Physiology (76)  |  Predict (12)  |  Scan (3)  |  Time And Space (30)  |  Transcend (10)

There was yet another disadvantage attaching to the whole of Newton’s physical inquiries, ... the want of an appropriate notation for expressing the conditions of a dynamical problem, and the general principles by which its solution must be obtained. By the labours of LaGrange, the motions of a disturbed planet are reduced with all their complication and variety to a purely mathematical question. It then ceases to be a physical problem; the disturbed and disturbing planet are alike vanished: the ideas of time and force are at an end; the very elements of the orbit have disappeared, or only exist as arbitrary characters in a mathematical formula
Address to the Mechanics Institute, 'An Address on the Genius and Discoveries of Sir Isaac Newton' (1835), excerpted in paper by Luis M. Laita, Luis de Ledesma, Eugenio Roanes-Lozano and Alberto Brunori, 'George Boole, a Forerunner of Symbolic Computation', collected in John A. Campbell and Eugenio Roanes-Lozano (eds.), Artificial Intelligence and Symbolic Computation: International Conference AISC 2000 (2001), 3.

Whether statistics be an art or a science... or a scientific art, we concern ourselves little. It is the basis of social and political dynamics, and affords the only secure ground on which the truth or falsehood of the theories and hypotheses of that complicated science can be brought to the test.
Letters on the Theory of Probabilities (1846), trans. O. G. Downes (1849).

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
