INTRODUCTION Is it not reasonable to anticipate that our understanding of the human mind would be aided greatly by knowing the purpose for which it was designed? Research Background The human mind is the most complex natural phenomenon humans have yet encountered , and Darwin's gift to those who wish to understand it is a knowledge of the process that… (More)
A daptation and Natural Selection began as a polemic. In the s, the evolutionary biolo-Wright had combined Darwinian natural selection with Mendelian genetics to develop a rigorous mathematical evolutionary theory. But thirty years after this " modern synthesis, " George Williams found that evolutionary thought had grown flabby and popular understanding… (More)
While evolution by natural selection has long been a foundation for biomedical science, it has recently gained new power to explain many aspects of disease. This progress results largely from the disciplined application of what has been called the adaptations program. We show that this increasingly significant research paradigm can predict otherwise… (More)
Let's not have a sniffle, Let's have a bloody good cry. And always remember the longer you live, The sooner you'll bloody well die!-From an old Irish ballad T he plane sat on the Minneapolis runway in the hot June sun of 1970, the air inside stuffy to the point of apprehension. A white-haired woman, about seventy, turned to the young man in the seat to her… (More)
Potentials for which the corresponding Schrr odinger equation is maximally superinte-grable in three-dimensional Euclidean space are studied. The quadratic algebra which is associated with each of these potentials is constructed and the bound state wave functions are computed in the separable coordinates.
Thoughtful contemplation of the human body elicits awe-in equal measure with perplexity. The eye, for instance, has long been an object of wonder, with the clear, living tissue of the cornea curving just the right amount, the iris adjusting to brightness and the lens to distance, so that the optimal quantity of light focuses exactly on the surface of the… (More)
Diseases result usually from webs of interacting causes of enormous complexity, while human minds seek explanatory principles of extraordinary simplicity. This conflict gives rise to a central problem for medicine. Explanations of disease, and most programmes of medical research , tend to emphasize a single cause, while most diseases result from multiple… (More)
1 Abstract The Teukolsky-Starobinsky identities are proven for arbitrary spin s. A pair of covariant equations are given which admit solutions in terms of Teukolsky functions for general s. The method of proof is shown to extend to the general class of spacetimes considered by Torres del Castillo.
In this article the separation constants for the spin one and gravitational perturbations in Kerr geometry are characterised intrinsically. The characterisations are given for the corresponding Hertz potentials and induced for the corresponding vector and metric perturbations using the results of Cohen and Kegeles. 1. Introduction. One of the remarkable… (More)
