After completing his PhD in astrophysics at the University of Cambridge, John Gribbin worked for five years on the editorial staff of the journal Nature, chiefly responsible for the daily Science Report in the Times. He left in 1975 to join the Science Policy Research Unit of the University of Sussex, working in the "futures" team on a study of the likely impact of climatic change on world food supplies. A book about the work of SPRU-Future Worlds-was the main result of this three-year stint. Since 1978, John Gribbin has been Physics Consultant to the weekly magazine New Scientist. His books published to date range from astronomy through geophysics and climatic change to human evolution, and include two novels written jointly with Douglas Orgill. They included White Holes (1977), Timewarps (1979), Genesis: The Origins of Man and the Universe (1981) and The Monkey Puzzle (co-author with Jeremy Cherefas, 1982): the novels are The Sixth Winter (1979) and Brother Esau (1982). As well as being a consultant to New Scientist, John Gribbin contributes to the "Futures" section of the Guardian and to broadcasts on the BBC World Service, British Forces Radio, and occasionally on the BBC's domestic services. His interest in the puzzle of gravity and warped spacetime goes back to his student days in Cambridge, when he won two awards for work on these themes. Married with two sons, John Gribbin was born in 1946 and lives in Lewes.Gribbin, John is the author of 'In Search of Schrodinger's Cat Quantum Physics and Reality', published 1984 under ISBN 9780553342536 and ISBN 0553342533.
