Historical and other considerations regarding the crystal form of sodium-ammonium d- and l-tartrate,potassium d- and l-tartrate,potassium-ammonium d- and l-tartrate,and potassium racemate.—II

In 1914, the physics discipline had reached a very similar stage of development in Australia and Japan. A generation later the paths of development had considerably diverged. A systematic comparison of the evolution of physics in the two countries during these years identifies factors—political, economic and cultural—that led to this divergence, but it also uncovers a number of underlying parallels.
