...local grade school in Thuin in 1934, retired 13 years later to complete work on his invention and to publish his findings in a book, Nombres En Couleur (1951). Cuisenaire's brainchild was a set of ten different colored wooden rods ranging in length from 1 cm. to 10 cm...
...Cuisenaire rods helped budding arithmeticians learn the basics of addition and subtraction. Example: using sight and touch, a child could tell that a 3-cm. green rod plus a 5-cm. yellow rod equaled an 8-cm. brown...
...time, money and lost observations," grouses Radio Astronomer Frank J. Kerr of the University of Maryland. What makes the situation even worse, he explains, is that the satellites use a portion of the radio spectrum especially important to radio astronomy. SMS-1, for instance, operates near the 18-cm. band, which is the natural wave length of hydroxyl, one of the first molecules discovered in space. It is from the signals of the hydroxyl molecule (which consists of one atom of hydrogen and one of oxygen) that radio astronomers have been learning about star formation and the nature...
AT56 broadcasts near an even more important frequency: the 11-cm. band, which has been specifically set aside by the International Telecommunications Union for the use of radio astronomers in their explorations of quasars, pulsars, distant galaxies and even the sun. Trouble is, the signals from these celestial sources are often so faint that they can be easily overwhelmed by signal spillover from the satellites' powerful radio transmissions, even when the complex craft are in a different part...
...specialized in female and pediatric surgery since he made Navy medicine his career. He has performed hundreds of mastectomies. After the anesthesiologist gave the go-ahead at 8:05 a.m., Fouty cut into the breast and within about ten minutes had removed the lump. It proved to be 2 cm. in circumference-no bigger than the tip of a man's little finger. A technician rushed the lump to the pathology department, where it was fast-frozen with liquid nitrogen. A thin slice was cut, which a pathologist examined under a microscope. Within five minutes the message was relayed...
