Document Summary
The discovery of cells: first seen in primitive microscope by robert hooke, better lenses- more precise images/smaller things anton van leeuwenhoek. Variations on the optical microscope: visible light microscopes, microscopes that use visible light, described by their field four types. Electron microscopy interference focused electron beam: wavelength=6pm, 100,000 x less than red visible light. The discovery of effects of microbes: ancient belief: disease/spoilage spontaneous generation, things left out go bad. Not some spontaneous generation factor in air that gets destroyed by heat. The development of medical microbiology: the discovery of spores and sterilization, louis pasteur: most heated solutions no contamination if no direct air exposure, john tyndall: some microbe has very high heat resistance- difficult to destroy. Heat sometimes not enough: ferdinand cohn: heat resistance due to spores better sterilization, the development of aseptic technique, from ancient times vapors from dead/decaying cause disease, mid-(cid:1005)8(cid:1004)(cid:1004)"s maybe microorganism cause disease.
