Page 198 - According to this principle, the strains that are produced in a body by the application, to a small part of its surface, of a system of forces statically equivalent to zero force and zero couple, are of negligible magnitude at distances which are large compared with the linear dimensions of the part.

Page 325 - Thus on our circular disc, or, to make the case more general, in every gravitational field, a clock will go more quickly or less quickly, according to the position in which the clock is situated (at rest). For this reason it is not possible to obtain a reasonable definition of time with the aid of clocks which are arranged at rest with respect to the body of reference. A similar difficulty presents itself when we attempt to apply our earlier definition of simultaneity in such a case...
Page 963 - A for which p^ and p2 are 1-1 and 6-2 respectively. The result is shown in fig. 5. It will be seen that the hard gamma radiation is much more destructive than the longer wavelength. 2 — Suppose the energy required to cause a certain other change is higher and of the order of the energy left in the cell during a single passage of the slower electrons corresponding to the longer wave-length, rx still equals...

Page 325 - Section 12, it follows that the latter clock goes at a rate permanently slower than that of the clock at the centre of the circular disc, ie as observed from K. It is obvious that the same effect would be noted by an observer whom we will imagine sitting alongside his clock at the centre of the circular disc.
