摘要:

The quasistellar object, the pulsar, the neutron star have all come onto the scene of physics within the space of a few years. Is the next entrant destined to be the black hole? If so, it is difficult to think of any development that could be of greater significance. A black hole, whether of “ordinary size” (approximately one solar mass,1 M⊙), or much larger (around106 M⊙to1010 M⊙,as proposed in the nuclei of some galaxies) provides our “laboratory model” for the gravitational collapse, predicted by Einstein's theory, of the universe itself.

摘要:

Are there good problems for solid‐state physicists in metallurgy? I believe so, both from the physicist's and the metallurgist's point of view. On the one hand are the important unresolved scientific questions, and on the other are industry's needs for special materials. A brief survey of the ways physicists can help those who study the uses of metals will show an underlying theme. Metallurgists need theories that can help them generalize from diverse experimental data without depending on detailed quantum‐mechanical models; they need phenomenological theories.
