...EINSTEIN'S GIANT LENS...
...they're just too faint for any telescope now in existence. But the universe itself has supplied a way of boosting a telescope's magnifying power. The theory of relativity says massive objects warp the space around them, diverting light rays from their original path. In the 1930s Albert Einstein realized this meant a star, say, could act as a lens, distorting and amplifying the light from something behind it. In practice, he said, it probably happens so rarely that we will never...
...Einstein was wrong. So-called gravitational lenses have become a major factor in modern astronomy. They have revealed, among other things, the existence of tiny planets around stars thousands of light-years away and have created weird optical effects, including multiple images of faraway quasars. If you look at a massive cluster of galaxies, Ellis figured, you might see amplified images of more distant galaxies, too faint to be seen otherwise. So a year or two ago, he started aiming the Keck at galactic clusters, and along with Stark, he identified six candidate objects. To make certain that these were...
...Baby Einstein vs. Barbie Overscheduled kids. Overprotective parents. They're hot-button media issues, but are they really the problems faced by most American families...
...brainy people not like them.’” A full 70 percent of 11-15 year old students did not picture scientists as “normal and attractive men and women.” Asked to draw a picture of a scientist, most children draw Einstein-types, with shocks of white hair, lab coats, and thick glasses. These views haven’t changed much since the mid 20th century. A 1981 study in Public Opinion Quarterly by Georgine Pion and Mark Lipsey echoed the BBC’s article: “In early studies...
