The First Microscope
This the first microscope invented in 1959. Hans and Zacharias Janssen made the first microscope by placing two lenses in a tube. -
Robert Hooke
Robert Hooke had studied a thin piece of a cork, and found that there were cells. (pores) -
Antony van Leeuwenhoek
He invented the single-lens microscope. -
Theodor Schwann
He confirmed that, "All living things are composed of cells and cell products". -
Matthias Jakob Schleiden
Schleiden wrote Contributions to Phytogenesis in 1838, when he said that the different parts of the plant organism are composed of cells. -
Cell Theory
All living things are made up of cells, all cells come from pre-existing cells, cells are the main building blocks of cells, the well being of an organsim depends on the well-being of its cells. -
Rudolf Virchow
He stated that "Every cells comes form a pre-existig cells." -
The Electron Microscope
An electron microscope is a type of microscope that uses a beam of electrons to light the specimen and produce a magnified image. Electron microscopes have a greater resolving power than a light-powered optical microscope, because electrons have wavelengths about 100,000 times shorter than visible light, and can achieve better than 50 pm resolution and magnifications of up to about 10,000,000x, -
X-Ray Microscope
these microscopes use a beam of x-rays to create an image. Because of a small wavelength, the image quality is higher than in optical microscopes. The maximum useful magnification is therefore also higher and is between the optical microscopes and electron microscopes. -
Scanning Tunneling Microscope
This type of Microscope can magnify up to 1 000 000 times! (STM) uses an electron beam not only to image things, getting resolution at the atomic level, but actually control them too.
