Archaeology's Tech Revolution

Let′s face it, Indiana Jones was a pretty lousy archaeologist. He destroyed his sites, used a bullwhip instead of a trowel and was more likely to kill his peers than co-author a paper with them. Regardless, "Raiders of the Lost Ark," which celebrates its 30th anniversary on June 12, did make studying the past cool for an entire generation of scientists. Those modern archaeologists whom "Raiders" inspired luckily learned from the mistakes of Dr. Jones, and use advanced technology such as satellite imaging, airborne laser mapping, robots and full-body medical scanners instead of a scientifically useless whip.

Such innovations have allowed archaeologists to spot buried pyramids from space, create 3-D maps of ancient Mayan ruins from the air, explore the sunken wrecks of Roman ships and find evidence ofheart disease in 3,000-year-old mummies. Most of the new toolkit comes from fields such as biology, chemistry, physics or engineering, as well as commercial gadgets that include GPS, laptops and smartphones.
