... widened his range yet further with work on control systems; on active control of sound, or antisound; more and more on waves; on oceanography and atmospheric dynamics, including monsoon prediction and propagation; and on biological mechanics at the microscopic level.
... lumalawak ang kanyang saklaw pa sa karagdagang trabaho sa control system; aktibo sa kontrol ng tunog, o antisound; at mas higit pa sa waves; sa oseanograpya at atmospheric dinamika, kasama na ang tag-ulan hula at pagpapalaganap; at sa biological mechanics sa mikroskopiko antas.
