Physicists are involved in a wonderfully diverse and varied set of enterprises, not simply and necessarily related. Your speaker is not distinguished by the development of his imagination; almost everything that happens amazes him. I shall not try to give a general landscape of all that physicists are up to. It ranges from the magnetohydrodynamics of interstellar matter to nuclear alignment at low temperatures; it ranges from the giant rocket to transistors, and to instruments for detecting valuable minerals in the ground; it ranges from automation to the coding problem of genetics; it ranges from teaching doctors and engineers and soldiers, and even ordinary men, to advising the heads of state.
