Luis Alvarez will probably be remembered best not for the work in elementary particle physics that earned him the Nobel Prize in 1968 but for his work in geology: He posited the definitive theory explaining why dinosaurs became extinct. His interest began with a rock whose layer of clay had been formed 65 million years ago. Working with his son, Walt, a geologist, and a pair of nuclear physicists, Frank Asaro and Helen Michel, Alvarez concluded "that a 10-kilometer piece of the solar system debris hit the Earth 65 million years ago and threw dust into the stratosphere that made the sky dark as midnight for several years, thereby stopping photosynthesis (preventing vegetation from growing)

Alvarez: Adventures of a Physicist by Luis W. Alvarez (Basic: $19.95; 292 pages) Few Nobel laureates in the sciences go on to do important work after getting the prize. There are several explanations for this. For one thing, the Nobel is typically awarded 10 or 15 years after the work it honors was done, by which time the distinguished scientist is past his prime.

Luis W. Alvarez, who won the 1968 Nobel Prize in physics for his work on the fundamental particles of the universe, but who became much better known for his controversial theory that the dinosaurs became extinct after an asteroid collided with Earth, died Wednesday night at the age of 77. His wife, Janet, said his health had been in decline since he underwent surgery last fall for a benign brain tumor. After the surgery, he developed cancer of the esophagus.

The mass extinctions of dinosaurs and other organisms 65 million years ago were the consequence of disturbances triggered deep within Earth, rather than asteroids crashing into Earth, says British geologist Anthony Hallam of the University of Birmingham.

Dinosaurs may have survived a cataclysmic collision between an asteroid and the Earth 65 million years ago by hibernating, casting doubt on a theory blaming the event for their extinction, a researcher says. Scientists have speculated in recent years that a huge object from space crashed into Earth with such force that a cloud of dust filled the air, blocking sunlight and killing plants and animals, including dinosaurs.
