While a survey of modern astronomy must cover a vast panorama of topics, conducting a similar exercise for all of physics is an order of magnitude more difficult. Indeed, the latest physics survey by the Board on Physics and Astronomy of the National Research Council (NRC) started in 1992 and has only just been completed.
