MICROSCOPE
Microbiology, the branch of science that has so vastly extended and expanded
our knowledge of the living world.
Leeuwenhoek, In 1673 introduced the world to the existence of microbial forms
of life.
Over the years, microscopes have evolved from the simple, single lens
instrument of Leeuwenhoek, with a magnification of 300x, to the present-day
electron microscopes capable of magnifications greater than 250,000x.
