...revamped. "Dormitory crewmen," earning $1.15 per hour, replace the porters of the last few years, who earned $.85 hourly. The cleanup crews will neither make beds nor dust, but will be concerned solely with cleaning floors and bathrooms in what Graham R. Taylor, Director of Student Employment, described as "heavier, rougher cleaning...
...unknown, cosmologists must test their models against the few facts they do possess. One set of facts they are reasonably sure of: the universe "is made of a fairly uniform mixture of chemical elements; 95% is hydrogen, nearly 5% is helium formed in stars. The small remainder is the heavier elements from lithium to uranium. The elements get scarcer as they get heavier until they reach the atomic weight of 100; after that, their abundance is about the same...
...started life with the great-great-grandfather of all explosions. The universe was then small, dense and hot, and was made up entirely of radiation and neutrons. As it exploded and expanded, most of the neutrons split into protons and electrons (hydrogen). A few joined together to form the heavier elements. It was all over in about 15 minutes; since then, the abundance of heavier elements has remained about the same...
...elements, the same set of cosmic facts that is the principal support of the explosive universe theory. Some stars made of hydrogen explode as supernovae. Their temperature and density are known roughly from observation, and they are high enough to make hydrogen atoms join together, forming all the heavier elements in about the right proportion. The explosion distributes them throughout the galaxy, and supernovae are frequent enough to supply all the heavy-element "impurities" that a typical galaxy possesses...
Department-store sales were also up 4% over last year. Despite the heavier buying, the Securities & Exchange Commission announced that individual savings during 1954's first quarter reached $3.3 billion, the highest savings in a postwar first quarter, and up $900 million from...
