...original prime numbers. To use a simple example: if the encoding key were 323, the decoding key would have to be 17, 19 (since 17 X 19 = 323). If a code breaker wanted to decipher the secret message, he would first have to factor the product-in other words, extract the original two prime numbers that are the source of the decoding key. But even in the computer age, factoring, which can involve trying out seemingly endless combinations of numbers, is an extremely time-consuming process. While it may be easy to factor a low number like 323, Rivest calculates...

...RESULT of such problems has been an alarming increase in the incidence of disease and malnutrition among the very young. Babies fed with formula under inappropriate conditions are caught in a vicious, ultimately debilitating cycle--underweight babies are prone to infections causing diarrhea, and babies with diarrhea extract fewer nutrients from the food they eat, aggravating the malnutrition. Bottle formulas lack the immunilogical benefits of breast feeding, which are especially key in unsanitary conditions.

Europeans are so eager for America to defend the dollar, Triffin argues, that they would willingly make the additional loans. Indeed, he believes that in return for propping the dollar, America could extract a quid pro quo, notably persuading the reluctant West Germans and Japanese to expand their economies in order to enhance world recovery. "It is in the interest of all governments to intervene to lift the dollar," Triffin says persuasively. "The problem simply cannot be left to the tender mercies of the speculators...

...point she was led through interminable prison corridors on the promise of a visit from Pasternak. Instead, she was thrown into the morgue. After she came to among the cadavers, she miscarried. Following Pasternak's death, she was again arrested. This time her tormentors tried to extract a confession that she had written Doctor Zhivago herself. When this tactic proved untenable, she was charged with accepting some of Pasternak's foreign royalties and sent to a concentration camp for four years...
