Abstract For an unbalanced rotor, amplitudes of vibration are given for different rates of constant angular acceleration and deceleration. The setup used to obtain these results on the differential analyzer at the Massachusetts Institute of Technology is described briefly and shown diagrammatically. The selection of spring constant, damping, and mass of suspended unit as a means of avoiding serious vibration in bringing a heavily unbalanced spring-mounted rotor up to speed is discussed in connection with the results.

On July 20, 1949 what are thought to be the first photographs of the radar indication of lightning strokes were obtained by the Weather Radar Research Project of the Massachusetts Institute of Technology. The method of radar lightning detection is described, and suggestions are made for research in this field. Possible uses of the observation include positive determination of certain precipitation cells as thunderstorms and their identification as such in rareps.

Rudiger Dornbusch, destacado economista del Massachusetts Institute of Technology (MIT), analiza en esta trascendental obra tópicos como inflación, deuda, tipos de cambio, política externa y mercados emergentes. El marco conceptual descansa en la corriente de la escuela de Chicago, la cual parte del principio de que el mercado es el mecanismo que garantiza la creación del progreso en contraste con el Estado, que en su afán por encontrar soluciones perfectas, fracasa regularmente en sus cometidos.
