Govindjee
Govindjee (born 24 October 1932) is an Indian-American scientist and educator. He is Professor Emeritus of Biochemistry, Biophysics and Plant Biology at the University of Illinois at Urbana-Champaign, where he taught from 1961 until 1999. As Professor Emeritus since 1999, Govindjee has continued to be active in the field of photosynthesis through teaching and publishing. He is recognized internationally as a leading expert on photosynthesis. Early life and education Govindjee was born in Allahabad, India. He is known only by a single name, as his family by tradition did not use a surname. At University of Allahabad, he received his B.Sc. in 1952 and his M.Sc. in 1954. He studied at University of Illinois at Urbana-Champaign, earning his Ph.D. in 1960. He began his PhD work with Robert Emerson who discovered the Emerson effect. After Emerson died in a plane crash, Govindjee completed his PhD work in biophysics with Eugene Rabinowitch. He has written about both Emerson and Rab ...

Photosynthesis
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities. Some of this chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are synthesized from carbon dioxide and water – hence the name ''photosynthesis'', from the Greek ''phōs'' (), "light", and ''synthesis'' (), "putting together". Most plants, algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth. Although photosynthesis is performed differently by different species, the process always begins when energy from light is absorbed by proteins called reaction centers that contain green chlorophyll (and other colored) pigments/chromoph ...

Eugene Rabinowitch
Eugene Rabinowitch (1901–1973) was a Russian-born American biophysicist who is known for his work in photosynthesis and nuclear energy. He was a co-author of the Franck Report and a co-founder in 1945 of the ''Bulletin of the Atomic Scientists'', a global security and public policy magazine, which he edited until his death. Early life Rabinowitch was born Evgenii Isaakovich Rabinovich in Saint Petersburg; his parents were a lawyer and pianist. During WWI Rabinowitch studied chemistry in St. Petersburg. Initially a supporter of the Russian Revolution, he and his family fled to Kiev and then Warsaw with the onset of the Red Terror in late 1918. Ultimately fleeing to Germany, Rabinowitch was able to take a course Einstein taught on relativity, and attend academic events that included Max Planck and Max von Laue. He later worked with James Franck at Göttingen. After the Nazis came to power in Germany in 1933, Rabinowitch worked for a year with Nils Bohr in Denmark, before finding ...

Robert Emerson (scientist)
Robert Emerson (November 4, 1903 – February 4, 1959) was an American scientist noted for his discovery that plants have two distinct photosynthetic reaction centres. Family Emerson was born in 1903 in New York City, the son of Dr. Haven Emerson, Health Commissioner of New York City, and Grace Parrish Emerson, the sister of Maxfield Parrish. Emerson was the brother of John Haven Emerson the inventor of the iron lung. He married Claire Garrison, and they had three sons, and a daughter. Career Emerson received a master's degree in 1929 from Harvard, and received his doctorate from the University of Berlin working in the laboratory of Otto Warburg. Thomas Hunt Morgan invited him to join the Biology Division at the California Institute of Technology where he worked from 1930 to 1937, and again for a year in 1941 and 1945. From 1942 to 1945 he worked on producing rubber from the guayule shrub for the American Rubber Company. In 1947 he moved to the Botany Department of the Universi ...

Emerson Effect
The Emerson effect is the increase in the rate of photosynthesis after chloroplasts are exposed to light of wavelength 680 nm (deep red spectrum) and more than 680 nm (far red spectrum). When simultaneously exposed to light of both wavelengths, the rate of photosynthesis is far higher than the sum of the red light and far red light photosynthesis rates. The effect was early evidence that two photosystems, processing different wavelengths, cooperate in photosynthesis. History Robert Emerson described the eponymous effect in 1957. In his paper he observed that: # When plants are exposed to light having wavelength greater than 680 nm, then only one photosystem is activated; i.e. PS700 resulting in formation of ATP only. # When plants are exposed to light having wavelength less than 680 nm, the rate of photosynthesis was very low. # On giving both shorter and higher wavelengths of light, the efficiency of the process increased, because both photosystems were working t ...

Scientific American
''Scientific American'', informally abbreviated ''SciAm'' or sometimes ''SA'', is an American popular science magazine. Many famous scientists, including Albert Einstein and Nikola Tesla, have contributed articles to it. In print since 1845, it is the oldest continuously published magazine in the United States. ''Scientific American'' is owned by Springer Nature, which in turn is a subsidiary of Holtzbrinck Publishing Group. History ''Scientific American'' was founded by inventor and publisher Rufus Porter (painter), Rufus Porter in 1845 as a four-page weekly newspaper. The first issue of the large format newspaper was released August 28, 1845. Throughout its early years, much emphasis was placed on reports of what was going on at the United States Patent and Trademark Office, U.S. Patent Office. It also reported on a broad range of inventions including perpetual motion machines, an 1860 device for buoying vessels by Abraham Lincoln, and the universal joint which now can be found ...

1932 Births
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

University Of Illinois Urbana-Champaign Faculty
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university i ...
