    Edward Witten is an American theoretical physicist born in He is considered one of the leading physicists today and is known for his work in string theory, quantum gravity, and mathematical physics. Witten was the first physicist to win the Fields Medal, awarded in for his proof of the positive energy theorem in general relativity. In , Witten introduced his idea of M-theory, which proposed that the five known superstring theories were different limits of a single underlying theory. Witten has also made significant contributions to quantum field theory, general relativity, topology, and the AdS/CFT correspondence relating quantum field theories and quantum gravity. He currently works at the Institute for Advanced Study in Princeton.

    Cosmological constant versus quintessence

    Abstract: (arXiv)

    There is some bevis that the Universe is presently undergoing accelerating expansion. This has restored some credit to the scenarios with a non-vanishing cosmological constant. From the point of view of a theory of fundamental interactions, one may argue that a dynamical component with negative pressure is easier to achieve. As an illustration, the quintessence scenario is described and its shortcomings are discussed in connection with the nagging ``cosmological constant problem''.

    Michael Atiyah

    British-Lebanese mathematician (–)

    Sir Michael Francis Atiyah (; 22 April – 11 January ) was a British-Lebanese mathematician specialising in geometry.[4] His contributions include the Atiyah–Singer index theorem and co-founding topological K-theory. He was awarded the Fields Medal in and the Abel Prize in

    Early life and education

    [edit]

    Atiyah was born on 22 April in Hampstead, London, England, the son of jean (née Levens) and Edward Atiyah.[5] His mother was Scottish and his father was a Lebanese Orthodox Christian. He had two brothers, Patrick (deceased) and Joe, and a sister, Selma (deceased).[6] Atiyah went to primary school at the Diocesan school in Khartoum, Sudan (–), and to secondary school at Victoria College in Cairo and Alexandria (–); the school was also attended by European nobility displaced bygd the Second World War and some future leaders of Arab nations.[7] He returned to England and Manchester Gramma
