Light Microscope and Function



Norms of Nature: Naturalism and the Nature of Functions by Paul Sheldon Davies,

Norms of Nature: Naturalism and the Nature of Functions by Paul Sheldon Davies,
The components of living systems strike us as functional-as for the sake of certain ends--and as endowed with specific norms of performance. The mammalian eye, for example, has the function of perceiving and processing light, and possession of this property tempts us to claim that token eyes are supposed to perceive and process light. That is, we tend to evaluate the performance of token eyes against the norm described in the attributed functional property. Hence the norms of nature.What, then, are the norms of nature? Whence do they arise? Out of what natural properties or relations are they constituted? In "Norms of Nature, Paul Sheldon Davies argues against the prevailing view that natural norms are constituted out of some form of historical success--usually success in natural selection. He defends the view that functions are nothing more than effects that contribute to the exercise of some more general systemic capacity. Natural functions exist insofar as the components of natural systems contribute to the exercise of systemic capacities. This is so irrespective of the system's history. Even if the mammalian eye had never been selected for, it would have the function of perceiving and processing light, because those are the effects that contribute to the exercise of the visual system. The systemic approach to conceptualizing natural norms, claims Davies, is superior to the historical approach in several important ways. Especially significant is that it helps us understand how the attribution of functions within the life sciences coheres with the methods and ontology of the natural sciences generally.

Understanding the Light Microscope: A Computer-Aided Introduction with CDROM by David J. Goldstein,
Understanding the Light Microscope: A Computer-Aided Introduction with CDROM by David J. Goldstein,
Understanding the Light Microscope consists of four original computer programs with an explanatory book. Author Dan Goldstein says using the programs can teach aspects of microscopy and diffraction often missed from formal courses, adding, ..". what one non-mathematician has created should not be beyond the understanding of others!" The book aims to provide understanding at a level deeper than customary in existing texts and in a form accessible to microscope users, particularly biologists. It covers simple ray optics, the aberrations of "real" (thick) lenses, polarized light, and the influence of diffraction on imaging. The book can be read alone, but appreciation of its contents is greatly enhanced when used in conjunction with the programs. D J Goldstein was a Nuffield Dominion Travelling Fellow at Oxford University and a visiting Professor in Pittsburgh. He taught at the Universities of the Witwatersrand (Johannesburg, South Africa) and Sheffield (UK) while publishing research in embryology, histology, immunology, histochemistry and microscopy. Since retiring in 1989 as Reader in Anatomy at Sheffield University, he has been an independent research worker in biomedical science.

Light field - The light field, also known as the plenoptic function or radiance field, is a function that describes the amount of light travelling through every point in 3D space in every possible direction. Light transport is measured in radiance.

Inverted microscope - An Inverted microscope is a microscope with its light source and condenser on the top above the stage pointing down, and the objectives and turret are below the stage pointing up.

Bidirectional reflectance function - A material's bidirectional reflectance distribution function (BRDF) defines the ratio of light reflected from a surface to the incident luminosity. It is a function of phase angle \alpha, azimuth angle \phi, and angle of incidence i.

Cathodoluminescence microscope - A cathodoluminescence (CL) microscope combines methods from electron and regular (light optical) microscopes. It is designed to study the luminescence characteristics of polished thin sections of solids irritated by an electron beam.
