...mammoth instrument, made possible by a $70 million grant to Caltech by the W.M. Keck Foundation, will have an innovative mirror system nearly 400 in. in diameter, which is twice the width and has four times the light-gathering capacity of today's reigning optical telescope, the 200-in. Hale device at Mount Palomar, Calif. When astronomers begin using the new telescope in 1992, it will push back the visible limits of the universe by billions of light years. Says Howard Keck, president of the foundation: "I'm told it will permit one to see the light of a single...
...Keck telescope, as it will be called, is the first of a new generation of extra-large telescopes designed to overcome construction problems that have dogged sky gazers since before the Hale was dedicated in 1948. Photons (massless particles that transmit light) from an ancient galaxy may travel billions of light years through space before they speed down a telescope tube. But unless enough of them are collected, astronomers will not be able to see the galaxy's image. Gathering sufficient photons to register an image is accomplished by either taking long-exposure photographs or using a larger mirror system...
...advent of the computer has changed all that. Led by Astrophysicist Jerry Nelson, a team at the University of California designed an unorthodox mirror that will not be a continuous concave surface, like Hale's, but 36 hexagonal pieces of specially shaped glass, each 6 ft. across and 3 in. thick; the segments will be fit together and will move in concert to act as one giant parabolic mirror. That harmony is possible only with the aid of a computer- controlled sensing and positioning system, which will realign the components 100 times a second by as little...

This year alone, Japanese investors have salted away $25 billion in American bonds. Fortunately for the U.S., that cash is financing a large chunk of its budget deficit. Yoshino cited a light hearted suggestion by Chicago Economist David Hale that the U.S. and Japanese economies should get married. "After all," Yoshino said, "the Japanese propensity to save would help the American eagerness to spend and borrow...
