The British version of Feynman's Rainbow. This book tells the story of Leonard Mlodinow's first year on the Caltech faculty in the winter of 1981. It is the narrative of himself as a young physicist trying to find his place in the world and the wisdom of an old, and dying physicist who helped him, the legendary Richard Feynman. But it is also the story of this famous scientist's last days, his rivalry with fellow Nobel Laureate, Murray Gell-Mann, and the beginnings of string theory, now the leading theory in physics and cosmology.
