Last year the world's population passed 4 billion. Barring a holocaust brought on by man or nature, the world's population right now is the smallest it will ever be again. How did it reach 4 billion? For the first 99% of man's existence, surprisingly slowly. For the last 1% of history, in a great rush. By 1750, the total had reached only about 800 million. Then, as the Industrial Revolution gathered momentum, population growth began rapidly to accelerate. By 1900, it had doubled to 1.6 billion; by 1964, it had doubled again...
...late 1700s Holden Chapel, one of the smallest buildings in the Yard, housed all of the facilities of the Harvard Medical School. With the school's faculty numbering only three, not too many people were concerned about who was in charge...
...years, the new science of gerontology (the study of aging) has expended prodigious efforts to locate life's master clock and perhaps use that precious knowledge to slow it or even stop it. One locale for the clock (if there is indeed only one) may be within the smallest unit of life, the cell. Growing normal embryonic cells of various species in a test tube, Biologist Leonard Hayflick has made an astonishing finding: they are not immortal, as scientists believed from early experiments, in which a single cell line had been cultivated for years, but have definite life spans...
While Kansas City's big boppers were providing the thunder, shortstop Freddie Patek, the smallest man in the majors, was right in the thick of each of his team's first two rallies...
...Home Appliance Manufacturers has been rating U.S.-made air conditioners, using the Energy Efficiency Ratio (EER), since 1974. On a scale advancing from a poor five to an excellent eleven, the EER evaluates the air conditioner's ability to produce the largest amount of cooling with the smallest amount of electricity. The EER tests show that the industry is indeed capable of producing machines that would meet strict new federal requirements; one of the main features of a more efficient unit is a large set of condensers and evaporator coils. But these machines are relatively bulky and cost more...
