The world religion is derived from the Latin noun religion, which denotes both (1) observance of ritual obligations and an inward spirit of reverence. In modern usage, religion covers a wide spectrum of (2) that reflects the enormous variety of ways the term can be (3) . At one extreme, many committed believers (4) only their own tradition as a religion, understanding expressions such as worship and prayer to refer (5) to the practices of their tradition. They may (6) use vague or idealizing terms in defining religion, (7) , true love of God, or the path of enlightenment. At the other extreme, religion may be equated with (8) , fanaticism, or wishful thinking.By defining religion as a sacred engagement with what is taken to be a spiritual reality, it is possible to consider the importance of religion in human life without making (9) about what is really is or ought to be. Religion is not an object with a single, fixed meaning, or (10) a zone with clear boundaries. It is an aspect of human (11) that may intersect, incorporate, or transcend other aspects of life and society. Such a definition avoid the drawbacks of (12) the investigation of religion to Western or biblical categories (13) monotheism or church structure, which are not (14) .Religion in this understanding includes a complex of activities that cannot be (15) to any single aspect of human experience. It is a part of individual life but also of (16) dynamics. Religion includes not only patterns of language and thought. It is sometimes an (17) part of a culture. Religious experience may be expressed (18) visual symbols, dance and performance, elaborate philosophical systems, legendary and imaginative stories, formal (19) , and detailed rules of some ways. There are as many forms of religious expression as there are human cultural (20) . 14()

"My own feelings went from disbelief to excitement to downright fear," says Carl Hergenrother, 23, an Arizona undergraduate who verified a large asteroid barreling toward Earth with a 230cm telescope atop nearby Kitt Peak. "It was scary, because there was the possibility that we were confirming the demise of some city somewhere, or some state or small country." Well, not quite. Early last week, his celestial interloper whizzed by Earth, missing the planet by 450620 km--a hairbreadth in astronomical terms. Perhaps half a kilometer across, it was the largest object ever observed to pass that close to Earth. Duncan Steel, an Australian astronomer, has calculated that if the asteroid had struck Earth, it would have hit at some 93460 km/h. The resulting explosion, scientists estimate, would have been in the 3000-to-12000-megaton range. That, says astronomer Eugene Shoemaker, a pioneer asteroid and comet hunter, "is like taking all of the U. S. and Soviet nuclear weapons, putting them in one pile and blowing them all up." And what if one them is found to be on a collision course with Earth Scientists at the national laboratories at Livermore, California, and Los Alamos, New Mexico, have devised a number of ingenious plans that, given enough warning time, could protect Earth from a threatening NEO. Their defensive weapons of choice include long distance missiles with conventional or, more likely, nuclear warheads that could be used either to nudge an asteroid into a safe orbit or blast it to smithereens. Many people including some astronomers--are understandably nervous about putting a standby squadron of nuclear tipped missiles in place. Hence the latest strategy, which in some cases would obviate the need for a nuclear defense: propelling a fusillade of cannonball-size steel spheres at an approaching asteroid. In a high-velocity encounter with a speeding NEO, explains Gregory Canavan, a senior scientist at Los Alamos, "the kinetic energy of the balls, would change into heat energy and blow the thing apart." Some astronomers oppose any immediate defensive preparations, citing the high costs and low odds of a large object’s striking Earth in the coming decades. But at the very least, Shoemaker contends, NEO detection should be accelerated. "There’s this thing called the ’giggle factor’ in Congress," he says. "people in Congress and also at the top level in NASA still don’t take it seriously. But we should move ahead. It’s a matter of prudence." The world, however, still seems largely unconcerned with the danger posed by large bodies hurtling in from space, despite the spectacle two years ago of Comet Shoemaker-Levy 9 riddling the planet Jupiter with mammoth explosions. It remains to be seen whether last week’s record near-miss has changed any minds. It seems that the writer is
