...Sagan, it is scientifically possible for Mars to harbor "macro-organisms" the size of polar bears, who crunch rocks for water, sport silicon skins to protect themselves against deadly sunburn, and hibernate for thousands of years at a stretch. Sagan also contemplates astro-engineered civilizations so far advanced that their accomplishments would seem to us "indistinguishable from magic." He can easily imagine intergalactic, rapid-transit routes where "an object that plunges down a rotating black hole may re-emerge elsewhere and elsewhen-in another place and another time...
Harvard's offensive power is almost a polar opposite from that of Yale, disdaining ball control for a big-play game plan that outfinesses opponents. "We won't be controlling the ball, but then again we never do. We'll just have to take advantage of the breaks that come out way and hope for a good game from Kubacki. Out strength (defense) will have to outplay their strength (offense), and the rest will take care of itself," Restic said...
Because the sun's rays strike it more directly, the earth's equatorial zone heats up more than either polar region. If some of this heat were not transported away from the tropics, average equatorial temperatures would probably begin to rise dangerously. Fortunately, the earth has some handy mechanisms for carrying heat from the tropics toward the poles. Perhaps a third of this heat is distributed by ocean currents. The rest is transported by movement of the atmosphere. A large portion of this atmospheric heat−the exact percentage is unknown−is picked up from...
...would happen if man ever interfered drastically with this process? Meteorologist Francis K. Davis, who is dean of Drexel University's College of Science in Philadelphia, warns of some frightening consequences. Unable to shake off their heat, he says, the tropics might become warmer and warmer. Simultaneously, the polar regions would slowly become colder. Eventually, both areas would expand, relentlessly shrinking the thickly populated temperate zones between them...
Winter, which brings down ferocious cold from the polar icecap, used to be a comparatively closed-down season, a deep hibernation. Snowmobiles, for better and for worse, have changed that. Many Minnesotans now worry about the ubiquitous high-pitched snarls of snowmobiles churning across the winter landscapes. Still, snowmobiling is the state's fastest-growing sport. Some 340,000 vehicles are licensed...
