Two odd tracks from high-energy cosmic rays in cloud chambers had been ascribed to V-particles and were cIassified as hooks and forks at Manchester University. The Caltech cloud chamber studies of many higher energy cosmic rays yielded similar complex events, some are illustrated in Leighton's textbook.

" I sympathized with my new astronomy graduate students who sometimes had to repeat some undergraduate physics courses. Yet, when I worked with former Caltech student Leverett Davis, Tr., in 1951 on the light scattered by spinning, elongated interstellar dust grains, Leverett remembered and found one of his Smythe problems, which gave the polarizability of an ellipsoid.
