Lavoisier s dictum that physics should precede chemistry became a logicohistorical interpretation, as he meant it to be, instead of a statement of pedagogical or disciplinary strategy. Paradoxically, the contemporary prestige of physics is associated with this logicohistorical tradition and with the classical and aesthetic appeal of abstract mathematics, rather than with the precision laboratory tradition on which much of modern physics, like chemistry, is based. The founder myth of Lavoisier has been perpetuated in the hagiography of the disciplinary clan of chemistry because of his role not only in the conceptual and linguistic foundations of nineteenth-century chemistry but also in a community of practitioners who refined the social definition of the chemical discipline its formal distinction from "physique" in the Paris Academy, its autonomous status as the subject of the Annales de Chimie, its Janus-faced position astride the abyss that previously divided the philosophical science of the university from the technical practice of the laboratory. 

When motivation became the object of scientific study, the same kind of exceptions to rational choice soon became apparent. Pavlov came up with the most robust solution—conditioned behavior, refined to conditioned motives, stated definitively in . H. Mowrer s two-factor theory (1947).1 In this form, Plato s passions seemed discernible in parametric research, and the ancient dual model was perpetuated. 

A perpetual holiday is a good working definition of hell. 

In liquid water, the thermal motions of molecules are perpetual, and the relative positions of the molecules are changing all the time. Although the structure of liquid water has no definite pattern, the hydrogen bonds between molecules still exist in large numbers. Thus liquid water is a dynamic system in which the H2O molecules self-assemble in perfect, imperfect, isolated, linked and fused polyhedra (Fig. 16.3.3), among which the pentagonal dodecahedron takes precedence. 

SRM which include CNS tissue are tissues from animals that are known to carry, transfer, or perpetuate infectivity of the BSE causative agent, prions. Because BSE is an adult-onset disease, identification of tissues as SRM is dependent on the age of the animal at slaughter, and definitions of SRM vary by country, based on differences in interpretation of scientific evidence and the amount of risk allowed (Table 1). Care must be taken when removing SRM (including CNS tissue) to prevent contamination of products due to improper or incomplete removal of SRM and to prevent cross-contamination of SRM to meat products via personnel or equipment. 

Frustrated by the inconsistencies associated with energy efficiencies, practitioners continue with new proposals of alternative definitions. Ironically, the vast majority persist in using energy as the measure of potential to cause change. Consequently, the frustrations are destined to be perpetuated. 

To perpetuate the name of Curie, the quantity of emanation in equilibrium with one gn.m of radium was termed a curie. This is an inconveniently large amount and the milli-micro curie is frequently used as a practical unit. It is the quantity of emanation in equilibrium with one millionth of a milligram of radium. Since one-fiftieth of this can be detected with a sensitive electroscope, this method of detecting the presence of radio-elements is extraordinarily sensitive — more so even than the spectroscope. The above definition of the curie has now been superseded. In July 1950 the Joint Commission on Standards, Units and Constants of Radioactivity defined the curie as the quantity of any radioactive nuclide in which the number of disintegrations per second is 3-700 X io10. 

While, as previously discussed, there is some consensus on the definition of inclusion (see also Ferdman, Chapter 1, this volume), the concept is open to widely varying behavioral interpretations. The specific behaviors and actions that exemplify inclusion are not consistent or well understood. Too often it is easier to perpetuate habitual exclusive practices rather than adopt new inclusive ones. To make the shift to an inclusive culture that will be sustainable over time requires a much broader and deeper approach than what has traditionally occurred in the name of diversity. Inclusion requires addressing both macro, systemic issues and ongoing micro behaviors that impact the experiences of individuals on a day-to-day basis. Inclusion also has to be driven both by top-down leadership and bottom-up engagement. 

In condensation problems dealing with very small droplets (with radius far below the mean free path) Gyarmathy s equations converge with the much simpler Hertz-Knudsen model involving the condensation coefficient a. This model is widely used although the condensation coefficient is not known. Mostly it is taken to be unity, however values as low as 0.01 are perpetuated [2]. Some of the uncertainty may be due to considerable confusion in the literature regarding its definition. Here we deal with it because our results render valuable information on its magnitude. 

Naturally occurring systems in the gaseous or liquid phase at typical temperatures are composed of vast numbers of atoms and molecules in constant motion. The well-defined system temperature is a reflection of the stored energy content, both in the form of mfermolecular features such as molecule-molecule interactions and translational motion and in the form of motion internal to individual molecules. The latter, the motion of isolated molecules, is termed mframolecular dynamics. Included within this definition are both dynamics at energies below the dissociation energy of the molecule, in which case it remains perpetually bound, and dynamics at energies above dissociation, in which case the molecule can break up into different chemical products. 

The history of science has always shown that science is in perpetual evolution and that the notion of definite theory is contrary to the quintessence of science which is to progress by invalidating [ falsifying as termed by Karl Popper (see Popper 2002)] admitted theories in order to propose new and improved ones.
