`This is a good article on J.A. Wheeler.However, the information regarding geometrodynamics is not accurate, especially the following statement: ``Wheeler abandoned it as fruitless in the 1970s``.As a matter of fact, Wheeler kept using the term ``geometrodynamics`` to describe Einstein's theory of general relativity till his last days. For example, in Gravitation and Inertia, a book written with the Italian physicist I.Ciufolini in 1995(and which was missing from the bibliography), the authors keep referring to ``Einstein Geometrodynamics``(the title of Chapter 2) throughout the the book: Chapter 3 is entitled `` Tests ofEinstein Geometrodynamics``, Chapter 5 is ``The Initial-Value Problem in Einstein Geometrodynamics`` and Chapter 7:``Some Highlights of the past and a Summary of Geometrodynamics and Inertia``.This proves that Wheeler did not abandon the concept at all in the 1970s!
