The introduction of the microscope as a tool for the biologist brought about a complete reappraisal of the micro- composition of biological tissues‚ organisms and cells. In the infancy of its application to organic materials‚ it was the implement of anatomists and histologists in particular‚ where previously unimagined structures in cells were revealed. More recent developments in biological specimen preparation have come from biochemists and physicists who have used the microscope to examine cells

NANOFABRICATION AND SCANNING PROBE LITHOGRAPHY Introduction: “Nanofabrication” is the process of making functional structures with arbitrary patterns having minimum dimensions currently defined (more-or-less arbitrarily) to be e100 nm. Microelectronic devices and information technologies have improved and will continue to improve as a result of large-scale‚ commercial implementation of nanofabrication. The motivation for these improvements is to increase the density of components

Introduction! ! The Michelson Interferometer is commonly used to determine the wavelength of light or measure very small distances. It was invented by Albert Abraham Michelson and is commonly used in optical interferometry‚ a branch of physics involving a family of techniques one could use to extract information about waves by superimposing them. ! ! The original application of the Michelson Interferometer was to the famous Michelson-Morley experiment in 1887. Prior to Einstein’s
