A journalist is an essential element in any responsible government. These people evaluate programs and activities the way food blenders process food. Tom Siegfried is a journalist but his target is not the government; it's physics and cosmology. He is gentler than a food processor and in Strange Matters, Undiscovered Ideas at the Frontiers of Space and Time he examines current and historical programs and activities, but of a scientific nature. He provides, like any good journalist, enough information to allow a reader to develop their own opinion, but not so much so as to preclude any choices.
