The X-Ray has been declared the most important scientific innovation by London's Science Museum.

Almost 50,000 people chose among 10 listed innovations, and voted at the museum's Web site. The X-ray machine garnered about 20 percent of the vote, finishing in front of penicillin and the discovery of the double helix. The electronic telegraph and steam engine were among the other discoveries offered.

"People are just fascinated with seeing inside their bodies -- even today," explained the museum's curator. "It has fundamentally changed the way we see and understand our world -- but particularly our bodies."

That being said, we're still wary of this conclusion. After all, the pre-selected list of 10 didn't even include the George Foreman Grill.
