microscope
Term: microscope
Origin: An Greek ??????/micros(=small) + ??????/scopos(=aim, look at)
Coined : Jansen and Jansen (1590), first produced a crude type of microscope by placing two lenses together without any provision for focussing. The Italian physicist Galileo Galilei, prepared a focussing devise in 1624 and named it "occhiolino" or "little eye". In 1625 Giovanni Faber coined the term microscopy although the father of microscopy is considered the Dutch trademark Van Leeuwenhoek (1632-1723). Leeuwenhoek had read ?Micrographia? of English inventor of compound microscope Robert Hooke (1635 ?1703), and he tried to grinded small lenses of short local length with a greater resolving power than that of Hooke?s microscope. . He made over 500 microscopes.

Electron Microscope
An electron microscope depends on electrons rather then light to view an object. Electron microscopes make it possible to view objects as small as the diameter of an atom. The electron microscope was invented in 1931....

Eye Glasses
Two dutch men created eye glasses with multiple lenses placed in a tube in 1590. The eye glasses made objects enlarged, creating the forerunner of the compound microscope and telescope. This helped us see objects appear very large then how we look at...

Cell Organization, And Viewing Cells
Cells need mobility, sustainability, most cell sizes and shapes reflect their functions, and this is necessary for their homeostasis. Ways of seeing: Phase contrast takes advantage of variations in density within cells. the density variations alter certain...
