For example, 341 rounded to the nearest hundred is 300. That is because 341 is closer in value to 300 than to 400. When rounding off to the nearest dollar, $1.89 becomes $2.00, because $1.89 is closer to $2.00 than to $1.00 Rules for Rounding Here’s the general rule for rounding: If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up....
Stardust captured the comet particles from Comet Wild-2 (pronounced Vilt) when the spacecraft flew within 149 miles of it on Jan. 2, 2004, roughly in the vicinity of Jupiter. The spacecraft’s collector swept up particles left in the comet’s wake, preserving them in a silicon material called aerogel, which cushioned and protected the particles on their long journey to Earth. The Stardust samples offer a time capsule to our primordial past....

For the original method of electing the President and the Vice President (elections of 1789, 1792, 1796, and 1800), see Article II, Section 1, of the U.S. Constitution. Only the 1960 race, in which John F. Kennedy squeaked out victory over Richard M. Nixon by just 0.1 of a percent, was closer. In fact, Kennedy’s triumph wasn’t official until noon the following day. And in 1976, Jimmy Carter also waited overnight to be declared the winner over Gerald Ford....

The Green Card, you see, has not always been green. In 1940, the Alien Registration Act (Smith Act) for the first time required all non-citizens age 14 and over to register and be fingerprinted....
To transport POWs home at the end of the war, the government offered shipping companies a fee for every soldier they carried north on the Mississippi. The Sultana, a 1,700-ton steamship with a capacity to carry only a few hundred people, crowded almost 2,500 soldiers aboard, and headed north for Cairo, Ill. A little north of Memphis, its boiler exploded. There were no life boats or life jackets. Another irony of the disaster is how little attention it received, despite its being America’s worst maritime disaster....
The West is a region of scenic beauty on a grand scale. All of its states are partly mountainous, and the ranges are the sources of startling contrasts. To the west of the peaks, winds from the Pacific Ocean carry enough moisture to keep the land well-watered. To the east, however, the land is very dry. Parts of western Washington State, for example, receive 20 times the amount of rain that falls on the eastern side of the state’s Cascade Range....
Many pounds of volcanic rocks were collected by astronauts during the various Apollo lunar landing missions. Only a small fraction of these samples have been subjected to exhaustive study by scientists. The bulk of the material is stored under controlled-environment conditions at NASA’s Lunar Receiving Laboratory in Houston, Tex., for future study by scientists. From the 1976-1979 Viking mission, scientists have been able to study the volcanoes on Mars, and their studies are very revealing when compared with those of volcanoes on Earth....
“Vote Yourself a Farm”: In the 1860 election, Abraham Lincoln strongly favored legislation that would give any person settling in the West a free homestead. “Full Dinner Pail”: William McKinley used the slogan in his 1900 campaign for reelection to recall the prosperity the country experienced during his first term. “He Kept Us Out of War”: The U.S. had not entered World War I during Woodrow Wilson’s first term (1913–1916)....
