'The progress and prosperity that humanity has achieved ...', writes John Browne, `is driven by people - scientists, business people and politicians'. The author has the rare distinction of having wide and deep experience of all three fields, and this is what makes Seven Elements such a fascinating and enjoyable book. Part popular science, part history, part memoir, these pages are infused with insight, shaped by the experience of a FTSE 100 Chief Executive and lifted by the innate optimism of a scientist.
