Viscosity Quotes
![When I started doing the 'Bursts' [paintings Gottlieb started c. 1958] I began to do part of the painting horizontally. It was necessary to do that because I was working with a type of paint which had a particular viscosity, which flowed, and if it were on a vertical surface it would just run. If it were on a horizontal surface, I could control it... I was using a combination of brushes and knives, palette knives... and spatulas... I've tried everything, rollers, rags, I've put paint on with everything. (Adolph Gottlieb)](https://cdn.quotesdtb.com/img/quotes_images_webp/35/adolph-gottlieb-begin-combination-425635.webp)
The whole science of heat is founded Thermometry and Calorimetry, and when these operations are understood we may proceed to the third step, which is the investigation of those relations between the thermal and the mechanical properties of substances which form the subject of Thermodynamics. The whole of this part of the subject depends on the consideration of the Intrinsic Energy of a system of bodies, as depending on the temperature and physical state, as well as the form, motion, and relative position of these bodies. Of this energy, however, only a part is available for the purpose of producing mechanical work, and though the energy itself is indestructible, the available part is liable to diminution by the action of certain natural processes, such as conduction and radiation of heat, friction, and viscosity. These processes, by which energy is rendered unavailable as a source of work, are classed together under the name of the Dissipation of Energy.
James Clerk Maxwell
The law of habit exhibits a striking contrast to all physical laws in the character of its commands. A physical law is absolute. What it requires is an exact relation. Thus, a physical force introduces into a motion a component motion to be combined with the rest by the parallelogram of forces; but the component motion must actually take place exactly as required by the law of force. On the other hand, no exact conformity is required by the mental law. Nay, exact conformity would be in downright conflict with the law ; since it would instantly crystallise thought and prevent all further formation of habit. The law of mind only makes a given feeling more likely to arise. It thus resembles the "non-conservative" forces of physics, such as viscosity and the like, which are due to statistical uniformities in the chance encounters of trillions of molecules.
Charles Sanders Peirce
...education should try to lessen the obstacles, diminish the friction, invigorate the energy, and should train minds to react, not at haphazard, but by choice, on the lines of force that attract their world. What one knows is, in youth, of little moment; they know enough who know how to learn. Throughout human history the waste of mind has been appalling, and, as this story is meant to show, society has conspired to promote it. No doubt the teacher is the worst criminal, but the world stands behind him and drags the student from his course. The moral is stentorian. Only the most energetic, the most highly fitted, and the most favored have overcome the friction or the viscosity of inertia, and these were compelled to waste three-fourths of their energy in doing it.
Henry Adams
