From the reviews: "This is a massive scholarly book on the work of David Hilbert on physics. In more than 400 pages the author provides us with an in-depth analysis of the fundamental contributions of this mathematician-born scientist to many branches of physics ... . the historical reconstruction, which was the main aim of the author is ... done with extreme competence and care, and it is, I think, of the highest quality." (Daniele Oriti, Mathematical Reviews, Issue 2006 i) "The main message of the book is that physics played in Hilbert's research ... a much larger role than is commonly recognized. ... It is written in a lively but at the same time in a very careful academic style. ... Throughout the book the reader is confronted with many interesting ... facts. ... Leo Corry's book is a significant contribution to Hilbert studies and will be a major reference source ... . I enjoyed reading the book and can recommend it to everyone."
