nov 18, 1902 - Ultra microscope
Description:
In 1902 Richard Adolf Zsigmondy, (1 April 1865,- 24 September 1929) an Austrian chemist, introduced an idea that led to the ultramicroscope, which makes it possible to observe very small particles by illuminating the preparation being studied in a direction that is perpendicular to the viewing angle. Richard Zsigmondy used the ultramicroscope to show the heterogeneous structure of colloids, which contain particles that are small but vary in size.
