Sorbei was a pioneer in the microscopic study of rocks · He devoted his life to original work in the study of spectra, microscopic and biological studies in addition to geology • Sorbei also studied archeology and hieroglyphic writing in Egypt and contributed to the establishment of the University of Sheffield.
He invented a method for making thin rock sections for microscopic study.

⏹ Salk Jonas Edward
Salk, Jonas Edward

American doctor and virologist (1914).
Salk studied medicine at New York University, then he soon shone in the subject of viruses at the University of Michigan, then at the University of Pittsburgh, where he worked as a professor of bacteriology. success against a number of viruses circulating in the United States.

⏹ Swellen, Ludolf van
Ceulen, Ludolf van

Dutch mathematician (1540-1610)
Swellen held the position of professor of immunization in - Leiden »
He devoted most of his life to calculating the value of the approximate ratio (i.e. 1 and 3), and he calculated it in the year 1910 to the thirty-fifth decimal place, this number - Ludolf's number, and it is possible to realize the difficulty of this work if we remember the absence of electronic computers at that time.

⏹ Swinburne, Sir James (9th Baronet)
@Swinburne. Sir James 9th Bart

British chemist (1858 - 1958)
Swinburne is known for his important research on phenolic gums. And he reached a way to synthesize these gums industrially and on a large scale he registered a patent for that, but Baekland preceded him to benefit from that synthetic method.
On this occasion, the name Baekeland is usually associated with the plastics called Bakelite. Swinburne was known as the father of British plastics.

⏹ Cyborg, Glen Tudor
Seaborg Glenn Theodore

American natural chemist (1912)
Seaborg worked as a professor of chemistry in California. He was famous for his research on the transition elements (the actinides group), and he helped discover plutonium, americium, and curium. Seaborg, in cooperation with his co-workers, was able to produce new elements industrially.

⏹ Cidenas

A Babylonian astronomer (from the fourth century B.C.) Sidinas was the head of a Babylonian astronomical school in Sippra. The credit goes back to this Babylonian astronomer for discovering the slow movement towards the west, which is shown by the equinox points on the great astronomical circle of the Earth, arising from the influence of the sun and moon on matter. protruding on the equator.

⏹ Cesalpini, Andrea Cesalpini, Andrea

Italian botanist (1519-1603)
Cisalpini worked as a professor of botany in Pisa, and he was the first to try to classify plants, so he divided them on the basis of types of fruits and flowers. Cisalpini prepared a complete classification that he published in Florence in 1583 under the title: De Plantis. This division had an impact on subsequent similar works.

⏹ Segré Emilio

Italian-American physicist (1905)
One of the students of the world famous physicist is Fermi - immigrated from his country in the period of fascism, to America.
Seeger worked with Chamberlain and together they discovered the anti-proton and together for this discovery they won the Nobel Prize for Physics in 1959.
Later, Seger was a professor of physics at the University of Berkeley, Berkeley, California.

⏹ Celsius, Anders

Swedish astronomer (1701 - 1744)
Celsius was interested in astronomical and natural studies, and worked as a professor of astronomy in Uppsala. Celsius is famous for making a Celsius thermometer in the year 1742, and the word “degrees Celsius” is still used instead of “degrees Celsius” in some European countries. The Celsius scale differs from other thermometers in that the freezing point of pure water represents one hundred degrees, while the boiling point of water represents zero degrees.
Celsius colleagues named Martin Stromer reversed the freezing and boiling points after inventing a thermometer. Celsius to its balance of eight years.

Sen, Richard Lawrence Millington
Synge, Richard Laurence Millington

British chemist (1914).
Sen participated with Martin, Arthur John, in important chemical research and shared with him the Nobel Prize for Chemistry in 1952 for their research on analytical chromatographic methods.
