A Quote by Wilhelm Ostwald

The well-known fact that the form of a specific substance, e.g. water, and hence its properties can alter without a change in composition was disposed of by the formal view that a physical, not a chemical, process was involved.

In the first quarter of the nineteenth century the experimental proof for the interdependence of the composition and properties of chemical compounds resulted in the theory that they are mutually related, so that like composition governs like properties, and conversely.

Wilhelm Ostwald

Life processes take place in an aqueous medium. All organisms are composed mostly of water, whether they dwell in the oceans, lakes, and rivers, or on the land. Because the physical and chemical properties of water are well suited to the requirements of life, it is no accident that life is a water-based phenomenon.

Robert E. Lee

The chemical compounds are comparable to a system of planets in that the atoms are held together by chemical affinity. They may be more or less numerous, simple or complex in composition, and in the constitution of the materials, they play the same role as Mars and Venus do in our planetary system, or the compound members such as our earth with its moon, or Jupiter with its satellites... If in such a system a particle is replaced by one of different character, the equilibrium can persist, and then the new compound will exhibit properties similar to those shown by the original substance.

Jean-Baptiste Dumas

Though I consider The Chronology of Water to be an anti-memoir for very precise reasons, it is an art form, and thus as open to "critique" as any other art form. Memoir has a form, formal strategies, issues of composition and craft, style, structure, all the elements of fiction or nonfiction or painting or music or what have you.

Oil companies are radical because they're willing to alter the chemical composition of the atmosphere.

Bill McKibben

The upshot is that most philosophers of biology now hold that biological properties supervene on physical properties (where supervenience is taken to include some kind of "in virtue of" relation), and that fitness and other biological properties are not identical with physical properties.

Elliott Sober

Flying over New Orleans on our approach, I got it. There was no view of land without water - water in the great looming form of Lake Pontchartrain, water cutting through in tributaries, water flowing beside a long stretch of highway, water just - everywhere.

Rachel Sklar

Water, the Hub of Life. Water is its mater and matrix, mother and medium. Water is the most extraordinary substance! Practically all its properties are anomolous, which enabled life to use it as building material for its machinery. Life is water dancing to the tune of solids.

Albert Szent-Gyorgyi

We have altered the physical, chemical and biological properties of the planet on a geological scale. We have left no part of the globe untouched.

David Suzuki

I think the most important work that is going on has to do with the search for very general and abstract features of what is sometimes called universal grammar: general properties of language that reflect a kind of biological necessity rather than logical necessity; that is, properties of language that are not logically necessary for such a system but which are essential invariant properties of human language and are known without learning. We know these properties but we don't learn them. We simply use our knowledge of these properties as the basis for learning.

Noam Chomsky

I'm interested in the fact that within science, you're dealing with properties of the real and physical world, and by using those properties you're really getting more in touch with the basis of reality and using that expressively.

Marc Quinn

I also assume that they are not simply the physical properties of things as now conceived by physical science. Instead, they are ecological, in the sense that they are properties of the environment relative to an animal.

James J. Gibson

There is not, in fact, any such thing as the direct influence of one human being on another apart from use of the physical environment as an intermediary. A smile, a frown, a rebuke, a word of warning or encouragement, all involve some physical change. Otherwise, the attitude of one would not get over to alter the attitude of another.

John Dewey

The properties of executability and universality associated with programming languages can be combined, in a single language, with the well-known properties of mathematical notation which make it such an effective tool of thought.

Kenneth E. Iverson

The concept of an independent system is a pure creation of the imagination. For no material system is or can ever be perfectly isolated from the rest of the world. Nevertheless it completes the mathematician's "blank form of a universe" without which his investigations are impossible. It enables him to introduce into his geometrical space, not only masses and configurations, but also physical structure and chemical composition. Just as Newton first conclusively showed that this is a world of masses, so Willard Gibbs first revealed it as a world of systems.
