FRIDAY: Key Largo, Huston and Bogert again, this time with Lauren Bacall and Edward G. Robinson, CM...
...American Movement (NAM) and the Cambridge Movement (CM) plan to send 15-20 of their members canvassing freshmen door-to-door during the next five days...
...atom of hydrogen, the most abundant element in the universe, which is shown undergoing a change of energy state (indicated by the different orientations of the orbiting electrons on the circles). During this process, the atom gives off a pulse of radiation with a wave length of 21 cm., which is also the message's basic unit of measure. For example, to the woman's right is the binary symbol for eight (D). Multiplied by 21 cm., the figure yields her height, 168 cm., or about 51 ft., which can easily be verified by comparing her size...
...Cornell Astronomer Frank Drake, Electrical Engineer Bernard Oliver composed a sample universal message that could conceivably have been sent from some distant planet. The information would be contained in a series of irregularly spaced pulses picked up by radio telescopes tuned to a wave length of 21 cm. (the natural frequency of radiation from a hydrogen atom and an obvious choice of an advanced civilization). Translated into print, the message would consist of an apparently meaningless sequence of 1,271 ones (for pulses) and zeros (for gaps between the pulses...
...that the alien race has six-fingered hands. Finally, the bracket at the lower right seems to measure the height of the adults and is labeled at mid-point by the binary number eleven. Because the only length that the senders and receivers know in common is the 21-cm. wave length of the transmitted signal, it can be assumed that the adults are eleven of those wave lengths, or 71 ft. tall...
