HOW THE MICROSCOPE IMPROVES SCIENCE FROM ITS BEGINNING AND ITS IMPACT ON THE SCIENCE OF BIOLOGY!!!!!! Time line for the development of the microscope. (1) 14th Century. Grinding lenses to make spectacles that will improve eyesight is discovered in Italy. (2) 1590. Hans and Zachanias Janssen from Holland discover the microscope by placing two lenses in a tube. (3) 1667. Robert Hooke begins to publish his results from using the microscope in science journals. (4) 1675. Blood, insects, cells and bacteria was first looked at by Anton van Leeuwenhoek. He used a very simple microscope with only one lens. (5) 18th Century. Scients discover that by using two different kinds of glass to make lenses that they can control the refraction of light. Microscopes became easy to use and become a favorite technology for scientists.(6) 1830. Blurring of images was a major problem. Joseph Jackson Lister solves the problem by using several weak lenses together. (7) 1878. Ernst Abbe uses mathematics to get maximum resolution in microscopes. (8) 1903. Richard Zsigmondy receives the Nobel Prize in Chemistry in 1925 for developing the ultramicroscope which can study objects below the wavelenth of light. (9) 1932. A scientist by the mane of Frits Zernike invents the phase-contrast microscope and begins the study of colorless and transparent biological materials. (10) 1938. The electron microscope is discoverred by ernst Ruska and receives the Nobel Prize in Physics for doing so. By using electrosn in the microscope the resolution of objects expands greatly and improves all of science. (11) 1981 The scanning tunneling microscope is invents by Gerd Binnig and Heinrich Rohrer. It makes three-dimensional images of objects and can be used to study atoms.
