Today (July 16, 1888) is the Birthday of Nobel laureate Frits Zernike, who invented the phase-contrast microscopy.

Today (July 16, 1888) is the Birthday of Nobel laureate Frits Zernike, who invented phase-contrast microscopy.

Frits Zernike was born on July 16, 1888, in Amsterdam, the capital of the Netherlands, in northwestern Europe. Zernike, whose father (Carl Friedrich August Zernike) and mother were "(Ansie Tiberink)" mathematics teachers, was naturally as interested in physics as his father. After completing his primary schooling in his hometown, Brits worked with his parents to solve some very complex accounts. Although he had little involvement in other subjects at school, including history, he was the first student in science subjects. Zernike, who studied chemistry, mathematics, and physics at the University of Amsterdam, won a gold medal in 1908 for his dissertation on theories of probability.

In 1908, he was awarded the Gold Medal by the Dutch Scientific Society for his extensive study of opalescence. In exchange for the gold medal, he received the money and spent the money on his experiments and doctoral research. Later, he accepted an invitation from a professor at Groningen University to work as his assistant. There he was appointed lecturer in mathematical physics, researching the errors of telescopic glasses. Zernike used his leisure time as a child to do many experiments and bought and tested several physics instruments from his storage. He was very interested in the study of glass, glass stones, and colors. He also researched the field of color photography and, due to a lack of funding, automatically developed the ether required for photo experiments. Through his research, he developed a camera and a small astronomical observatory.

Frits, who received his doctorate from the University of Amsterdam in 1915, was involved in research on visual acuity. He also researched spectrum lines and developed the Phase-contrast microscopy tool. At a physics and medical conference in Wageningen in 1933, he demonstrated the technology of the 'base contrast microscope' and used the same method to test the ability of convex lenses. Also, together with his students, he solved the problem caused by abnormalities in the lens systems. The Ramford Medal of the Royal Society of London, the Royal Academy of Arts and Sciences in the Netherlands, and Zernike, a member of several organizations, including the Royal Society, did not immediately receive recognition or recognition for the great invention of the Phase Contrast Microscope.

Many years later, in 1941, a large number of 'light contrast microscopes' were produced in Germany for World War II, after which his fame spread. In 1953, Britney Zernike was awarded the Nobel Prize in Physics for her work in various fields. The Ornstein Zernike equation, the Zernike transformation into polynomial expressions, the physical light variation towards the microscope, and many other sources and instruments, particularly the "Phase Contrast Microscope" (196) He passed away at the age of 77 in Amersfoort, the Netherlands.
