Dr John Norbury, Supernumerary Fellow of the College, has recently co-authored a book with Ian Roulstone entitled 'Invisible in the Storm - The Role of Mathematics in Understanding Weather'. The book was published on the 24th February 2013 by Princeton University Press. Invisible in the Storm is the first book to recount the history, personalities, and ideas behind one of the greatest scientific successes of modern times--the use of mathematics in weather prediction. Although humans have tried to forecast weather for millennia, mathematical principles were used in meteorology only after the turn of the twentieth century. From the first proposal for using mathematics to predict weather, to the supercomputers that now process meteorological information gathered from satellites and weather stations, Ian Roulstone and John Norbury narrate the groundbreaking evolution of modern forecasting.
