Peter Kosso is a philosopher of science. He taught physics at Montana State University, and taught philosophy first at Northwestern University, Illinois and then at Northern Arizona University. He is the author of Reading the Book of Nature, Appearance and Reality, and Knowing the Past, as well as numerous articles on relativity, quantum mechanics, astronomy, and scientific method.

'In Kosso's most recent work, the philosopher and physicist exhibits precision in language and thought. In a sense, What Goes Up is three works in one. A history of physics is intertwined with a non-mathematical conceptual physics text. Arising out of these two comes a philosophy of physics glue that binds the first two together. The evolution of one's 'understanding of gravity' … is used as the narrative, leading the reader from cover to cover. Philosophically, Kosso … helps the reader appreciate the scientific method as it comes to maturity out of a cooperation between observation and theory. He discusses such topics as the 'distinction between description and explanation', instrumentalism, and causal mechanisms. Especially easy to follow is his conceptual presentation on the metric and the manner in which the principle of equivalence leads to the gravitational red shift and the slowing of clocks - both normally difficult topics in general relativity.'
