...Army has laid down 20 runway sections insulated from the permafrost by layers of cellular concrete, asphalt, foam glass, gravel, moss and spruce boughs. Under each runway are thermometers to measure heat penetration. For buildings, the trick is to rest the walls on thick mats of insulating material, or allow cold air to circulate freely under heated floors. Roads will be insulated, too, to keep foundations frozen under thundering tanks and trucks...
Many will question the need for a watchdog of morality, especially in Boston. But Croteau cities Scollay and the "tenderloin" area (in and around lower Washington Street) as examples of what a surface-strict city will allow under the facade. Whether Watch and Ward can help has been a matter for frequent public debate. Certainly the Society's streamlined and neo-sociological methods in the field of vice-suppression cannot hurt. But along with the new methods has come expansion--Watch and Ward will move from its retreat to occupy the entire Christian Endeavor Building. Its new facilities will...
...Ridge scientists are sure that isotopes will have an enormous effect upon both science and industry. Most immediate use is as "tracers": delicate radioactive tags which allow a chemical substance to be followed step by step through an industrial process or the human body. Isotope enthusiasts believe that the tracers will explain the mysterious reactions inside living cells...
...slightly envious eyes turned southward, and for almost a decade following, agitation stirred around the Varsity club for the construction of a new stadium to out-class the monstrous New Haven teacup. Finally, in 1929, after holding his thumbs down for two years, President Lowell agreed to allow the addition of steel stands for the Oxford-Cambridge-Yale-Harvard Track Meet. This was the last large work performed on the stadium, and increased its seating capacity to something close to the present 57,426. Nobody much remembers what happened in the English-American track and field events--except that...
...planning any voyage, the space navigator would have to allow for a host of "perturbations." Distant objects such as Neptune or comparatively small objects such as the moon might pull the ship off its course. A round-trip voyage would be ticklish. The ship would have to circle the objective planet and come back just in time to meet the earth. A miss would mean a plunge toward...
