...last year Bridges was ready to demand a contract for the sugar workers, who had always been at or near the bottom of the economic pile. Imported by the thousands as indentured laborers from China, Japan, Portugal, Puerto Rico and the Philippines, they had once lived in virtual peonage...
...Radcliffe girl with her pile of books has increased the confusion in already crowded classrooms. She has taken with a minimum of mumbling the classroom changes at the beginning of each term, although she occasionally wonders whether she is attending the Peripatetic School or Harvard University.

She ignores the vertical stares of Harvard veterans although she is tempted to retaliate in kind...
...Piles for Power. The scientists who dominate the raw and regimented city are not relying on missionaries alone. They are giving the Atomic Age a mighty shove by designing a power-producing pile, the most promising peacetime application of nucleonics...
...Present piles (at Oak Ridge, Hanford and Chicago) are kept cool, but power piles will run at high temperature. Among the reacting uranium rods of a power pile will circulate a chemically inert gas, hot as a dragon's breath, deadly with radioactivity. This will heat a conventional boiler, yielding high-pressure steam, which, the scientists hope, will not be too radioactive to use in a turbine...
Isotope Rush. One group of Oak Ridge scientists is already doing a growing business in radioactive isotopes. Every week, with elaborate precaution, they pull a lead plug from a hole in the massive concrete shield around the Clinton pile. Out comes a graphite bar studded with little aluminum cans of chemicals which have been exposed to the storm of neutrons raging inside the pile. These contain the isotopes for which the world of science is clamoring. Sealed in heavy lead shipping cases, they are rushed to hospitals and research laboratories...
