The Prof will follow Churchill anywhere. Winston's motives for cultivating him are very different. Lindemann's many talents include a matchless gift as an interpreter of science for laymen. In the words of Sir John Colville, Lindemann can "simplify the most opaque problem, scientific, mechanic or economic," translating technical jargon into language which provides "a lucid explanation" and sacrifices "nothing of importance." Churchill loathes scientific terminology. He never even mastered public school arithmetic. The Prof provides him with the essential facts when he needs them without disrupting his concentration on other matters. Like radar, Lindemann's "beautiful brain," as Churchill calls it, will prove worth several divisions in the struggle to save England from Adolf Hitler. Less than ten years from now he will arrive at No. 10 Downing Street with clear, accurate charts which, by replacing statistics, present displays showing England's stockpiles of vital raw materials, the rate at which ships are being launched on the Clyde, the Tyne, and the Barrow, and Britain's production of tanks, artillery, small arms, and warplanes in terms the prime minister can understand with what Colville calls "infallible skill and punctuality."
