Using his microscopes, Leeuwenhoek reported the first discovery of protists (he called infusoria) in 1674 and bacteria (he described as “little animals” or animalcules) in 1783. He also observed the vacuole inside the cells, mobility of sperms, and the banded pattern on muscular fibers. [...
At their core, even today’s massive microscopes are considered compound microscopes. From Photons to Electrons In 1900, visible light microscopes reached their theoretic limit of resolution. Physics dictates light microscopes are limited to magnification of 500x to 1000x and a resolution of 0.2 micro...
In 1611, Johannes Kepler discovered total internal reflection and described the small angle approximation to the law of refraction. In 1621, Willebrord Snell made a major discovery: the law of refraction; the formulation of this law in terms of sines was later published by Ren´e ...

In the Netherlands, around 1590, Hans Janssen and his son invented a compound microscope—constructed of two convex lenses. In the early 1600s (about 1610), the great Galileo Galilei (1564–1642) constructed several simple microscopes and telescopes, which he called as “occhialino.” The term...

cameras. It is ideal for visual inspections of semiconductor wafers and electronics components, and can detect microscopic scratches and surface irregularities, which are difficult to confirm with the naked eye. It can also identify materials that are difficult to distinguish under visible light. ...
As of recently, the answer is yes. A Historical Introduction to Epigenetics Although often amusing to many modern biologists, serious scientific debate surrounded preformationism until the late 1700s. Peering through early light microscopes, some naturalists believed they could see entire miniature ...
