Energy unrealistic expectations

Social workers must remain keenly aware and educate clients so that they do not develop a false sense of security with regard to the curative nature of a pill for treating depression (Marano, 1999). The allure of a quick fix is strong when compared to engaging in supportive counseling that often takes substantial time, emotional energy, and effort. The mistaken belief that antidepressants can cure creates unrealistic expectations... 

It is unrealistic to expect that any single conformer of a polymer will adequately represent the overall size and shape of the polymer. The low-energy conformer for each polymer strand shown here is merely meant to allow identification of the polymer in terms of its components. 

As for the energies of non-bonded complexes, the failure of HF theory to account for dispersion tends to make such complexes too loose in structure, i.e., intermolecular distances are unrealistically large. Hydrogen bonded structures, on the other hand, are often quite good because errors in overestimating electrostatic interactions cancel the failure to account for dispersion. The HF structures show the expected preference for linear bond angles at hydrogen, when such are possible, and further exhibit reasonable distances between donor and acceptor heavy atoms in most instances. 

Like all models in science, the one treated in this chapter makes many unrealistic assumptions. These were pointed out at the end of Section 2. The most notable deficiencies are that the model inadequately reflects the cell division process and neglects the energy required for cell maintenance. It should be pointed out, however, that the main predictions of the simple (even less realistic) models of Chapters 1 and 2 survive intact in the more complex model treated in this chapter. Therefore, it is not unreasonable to expect that many of the predictions made on the basis of Theorem 4.1 will continue to hold for more realistic models. 

The use of an FPE, such as that developed in Section IIB, is not appropriate for the study of all aspects of vibrational relaxation, such as dephasing. Nevertheless it is not unrealistic to expect that the effective potential ( (P) of Eq. (2.26) and the relative friction of Eq. (2.34) will also characterize an appropriate three-dimensional formulation. In one dimension the energy diffusion equation of Zwanzig has been found to givea good...
