Botanists have eliminated the most expensive part of the nation's hybrid corn seed business. This is the claim made for a new breed of hybrid corn which will not require "detasseling." The breed was developed by Paul C. Mangelsdorf, professor of Botany, and Donald F. Jones of the Connecticut Agricultural Station, who announced their discovery today...
Results of comprehensive tests with the new method indicate, the scientists report, that it "promises to revolutionize the hybrid corn seed industry...
...Seed of the Abacus. The calculating machines that are Bessie's ancestors have roots far back in the past. The abacus, used in ancient Egypt and still used in much of Asia, is a simple figuring device. The French mathematician Blaise Pascal (1623-62) designed a mechanical calculator when Louis XIII was king. The present adding machine is a remote descendant of Pascal's design...
Blending powdered quartz, magnesite and bauxite, the bureaumen added a crystallizing agent (fluorosilicate compound) and melted the ingredients in a platinum-lined crucible at nearly 2,500° F. As the furnace cooled, mica sheets grew from tiny "seed crystals" at the coneshaped bottom of the crucible. Because crucibles lined with carbon or ceramic failed to do the trick, the bureau scientists used expensive platinum, hope to reduce costs by melting down the metal and reusing it time & again...
