...knows if Evans's prediction of a 15 per cent black freshman class will come true: the crystal ball remains fuzzy...
...balanced ecology. Its creatures are forms of organic machines that either benignly watch the visitors or drag off broken objects, thus keeping the landscape junk-free. But who built Rama and why remain a mystery, though the discovery of human-like artifacts encoded as 3-D blueprints in crystal columns suggests that Rama is some sort of vast ark in search of a new home. But in fact its only interest in the solar system is to tank up on the sun's hydrogen before rounding the next cosmic bend without so much as thank you. The probability that...
...chair, and a bureau--the bureau graced with an artificial daisy placed in a real flower pot.

Veteran Restorer Dino Dini, 61, called in a chemist from the University of Florence named Enzo Ferroni, who discovered that the crystal growth was caused by lime, or calcium carbonate, turning into calcium sulphate. It took a year to find an ammonia solution that would turn the crystals back into calcium carbonate again. Impregnating a postcard-size sheet of Japanese rice paper with the solution and backing the paper with wood pulp, Dini and an assistant pressed each little rice-paper block for five minutes on the surface...
