...Lower Miocene-and came across the familiar Sivapithecus and Proconsul remains. Applying 14 standard tests of the shape and size of jawbones and teeth to these long-ignored bone fragments, Leakey concluded that their characteristics were definitely more manlike than apelike, and reclassified them as Kenyapithecus africanus. Unlike the rectangular, one-rooted molars of apelike creatures, for example, the Kenyapithecus' molars were triangular and had two roots. Its incisors were in line with its canines; ape incisors protrude in front of the canines. Kenyapithecus' chin projected slightly to the front of its teeth; an ape's chin...
...rays at so big a circle when the target is a rectangle only 1 in. by 1½ in. To keep the X rays from fanning out, they must be "collimated"-made to follow parallel paths. In their machine, the Nashville dentists use a stainless-steel plate with a rectangular window to accomplish collimation; they also use much more shielding and a steel bracket to hold the film just where it ought to be, without subjecting the patient's hand to radiation. The result, according to PHS tests, is a radiation dose delivered to the skin only one-half...
Like the voice, the verse is direct, fervent, fresh, almost childishly naive. Some of it is tenderly lyrical; much of it is vehemently public poetry, poetry for the microphone. The imagery and language are startling, precise, modern. "Behind an airplane," he writes, "the sound trailed/ Rectangular, like a barge behind a tug." And again: "Radio-like, my cat lies curled/ With his green eye tuned to the world...
...rose higher in the lunar sky and temperatures climbed toward 270° F. Jet Propulsion Laboratory scientists prepared to shut down their successful Surveyor spacecraft for a two-day siesta. Then they suddenly discovered that the protective shadows of Surveyor's solar panel and rectangular high-gain antenna had fallen over the television camera, keeping it cool enough to shoot pictures for an extra day. Before the camera was again directly exposed to the sun's rays and had to be turned off, Surveyor raised its picture total to an incredible 4,002. After the siesta...
...Happy Dungeon. Most recently built of Kahn's inventory (see opposite page) is his Salk Institute for Biological Studies, overlooking the Pacific palisades in La Jolla, Calif. Selected by Dr. Jonas Salk, developer of the polio vaccine, Kahn designed the presently half-occupied institute as two yoked rectangular blocks facing seaward. Each block is composed of flexible laboratory spaces, spanned by floor-tall Vierendeel trusses, which, like punched-out beams, permit the tons of laboratory plumbing to pass through. Separated from the labs by stairways and passageways that serve as open terraces for outdoor seminars are the angled studies...
