Evolution of photosynthesis Evolution of photosynthesis The evolution of photosynthesis refers to the origin and subsequent evolution of photosynthesis, the process by which light energy synthesizes sugars from carbon dioxide, releasing oxygen as a waste product. The process of photosynthesis was discovered by Jan Ingenhousz, a Dutch-born British physician and scientist, first publishing about it in 1779. The first photosynthetic organisms probably evolved early in the evolutionary history of life and most likely used reducing agents such as hydrogen or electrons, rather than water. There are three major metabolic pathways by which photosynthesis is carried out: C photosynthesis, C photosynthesis, and CAM photosynthesis.
What Do You Care What Other People Think? What Do You Care What Other People Think? "What Do You Care What Other People Think?": Further Adventures of a Curious Character (1988) is the second of two books consisting of transcribed and edited, oral reminiscences from American physicist Richard Feynman. It follows "Surely You're Joking, Mr. Feynman!". Richard Feynman received the Nobel Prize in Physics in 1965 for his contributions to the development of quantum electrodynamics. He is a theoretical physicist known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, and the physics of the superfluidity of supercooled liquid helium, as
