...seemed just around the corner. Jenkins Television Co. was actually selling receiving sets for $119. Now Dr. C. Francis Jenkins is dead, and his company is defunct. The Jenkins sets were made for programs televised by mechanical scanners - rapidly revolving disks with holes or mirrors to juggle the scanning beam. The Farnsworth and RCA-Victor electronic scanners made junk of disk sets. Now, before jumping into television, the radio industry would like to be sure that another technical advance would not similarly scuttle the public's investment...
...Finding little information in anatomical literature on the tensile strength of human tendons, Alfred Eugene Cronkite of Stanford University took 294 tendons from corpses, stretched them between two receding clamps, noted the reading on a beam balance when the tendon broke. Experimenter Cronkite could find no clear correlation between tendon strength and age, cause of death or function of the tendon. In general the strength varied between 9,000 and 18,000 Ib. per sq. in. of cross section. One tendon from an 85-year-old man stood up under nearly 30,000 Ib. per sq. in., about...
...President Jack Frye: The Bureau changed its beacons and equipment without informing the airlines. On the occasion of Senator Cutting's death, the Kansas City radio beam was turned off while the plane was groping in fog overhead. Had it been in operation, the accident might not have occurred...
Earthquakes and glass flowers apparently never caused much concern among the architects of the University Museum. The massive horizontal timbers which support the several floors are not firmly attached to the walls. Instead, each end of the beam rests in an iron sling which is in turn suspended from a stout "bracketlike" bar, anchored in the wall masonry. All of which leaves the beam free to move in its supporting sling...

Following Order No. 3, the building is almost entirely of marble...
