Abstract
IN his Halley Lecture1, Prof. H. Dingle gave an outline of an entirely new application of relativity principles to thermal radiation. He has now published a more detailed account2 which shows how far the theory has been worked out. The fundamental idea is that "our theories should not imply the possibility of observing what is, in fact, unobservable". Thus in Einstein's theory of two bodies moving with uniform relative velocity, it is only this relative velocity and its limiting value which are of importance. Moreover, the equality of the inertial and gravitational mass is regarded not as a remarkable coincidence, but as establishing that these two masses are two aspects of the same property.
