1939Year PARIS, March 18.--What next? Everybody in Europe is asking that question. Since the days when Napoleon annexed countries overnight, made and broke puppet States, dictated to the whole Continent and kept his own people spellbound by the suddenness of his decisions and the success of his action the world has not known such tension as now.

1935Year TWO days before the harassed representatives of a befuddled Europe met recently in an unavailing effort to put a brake on him, Benito Mussolini made a pious and peaceful pilgrimage to a primitive old farmhouse in a hill village near his birthplace.

1990Year LEAD: Researchers at the Massachussetts Institute of Technology and the University of California at Berkeley have been working for years to develop micro-motors. Now, they say, they know a bit about how these tiny engines wear. ''We are beginning to get a foothold in understanding the wear process and in learning how bearings hold up,'' said Jeffrey Lang, an associate professor of electrical engineering at M.I.T., who is building the motors.

1994Year IN preparation for the first anniversary of the World Trade Center bombing late last month, the New York Police Department sent bomb-sniffing dogs to survey landmarks like the Empire State Building, the Statue of Liberty and other likely targets of terrorism. The dogs hunted inside but made a special survey of the perimeters, partly as a show, said John F. Timoney, the chief of police. "It was to let them know, whoever 'they' are, that we haven't forgotten," he said. Although the World Trade Center explosion has not been followed by similar acts of terror -- the police broke up a cell that was planning additional bombings around the 4th of July, at the Hudson River tunnels, the Federal Building in lower Manhattan, and other targets -- Chief Timoney said that he suspected the terrorists might still "be looking to make their mark."
