Science demonstrations

Tart, Science, 1972, 176 1203-1210, by permission of the American Association for the Advancement of Science) demonstrates some possible relationships between three state-specific sciences. State-specific sciences 1 and 2 show considerable overlap. 

Now since the good and the beautiful are different... those who assert that the mathematical sciences say nothing of the beautiful or the good are in error. For these sciences say and prove a great deal about them if they do not expressly mention them, but prove attributes which are their results or definitions, it is not true that they tell us nothing about them. The chief forms of beauty are order and symmetry and definiteness, which the mathematical sciences demonstrate in a special degree. 

FIGURE 144. One of the greatest science demonstrations of all time When von Guericke used his vacuum pump to remove the air from a sphere only 14 inches in diameter, teams of horses could not overcome the 2,260-pound (1.1-ton) force of atmospheric pressure pushing the hemispheres together [from Von Guericke s Experimenta Nova (1672)] (courtesy Edgar Fahs Smith Collection, Rare Book and Manuscript Library, University of Pennsylvania). 

Our experiments are organized such that we go through our "lesson plan" (air has mass and can do work, the relationship among three states of matter, and molecules are three dimensional) in an orderly fashion. Commercial applications of all the science demonstrated are discussed. Remember we want science to be viewed as useful, important and understandable. The selections continually evolve as we modify or exchange, but what follows is a representative list of experiments and a few words about the points each is to address.

All the latest studies in asphaltene science demonstrate repeated consistency with the modified Yen model proposed in Figure 11. This model provides a foundation that has far reaching implications in many areas associated with the production of crude oil. 

Je tasche de m y rendre intelligible et d eviter les expressions obscures dont se sont servis les autheurs qui en ont ecrit avant moy. .. la chymie est une science demonstrative . . . mon dessein est simplement de faciliter les moyens pour travailler en Chymie, et de depouiller autant que je pourray de ce qui la rend mysterieuse et cachee. ... 

IX The same arguments which demonstrate the usefulness of other sciences demonstrate the usefulness of critical research... 

The facility near infrared camera (NIRC) was used on the W.M. Keck telescope for a series of science demonstration observations in March 1993. These observations have served to demonstrate that the telescope delivers excellent images and can hold those images for wedcs. The telescope tracking under autoguider control is commensurate with the image quality. The performance of the camaa is consistent with that expected for an instrument on a 10-m telescope.
