By the Numbers – 2005-10-01

0 is a number that saved many lives in WWII. Planes riddled with bullet holes that made it back to bases were studied for the locations of where bullet holes (data points) were not, telling engineers where to reinforce designs. Zero also holds significant information in a location plot analysis, according to a recent Juran Institute's "Quality Minute.

23,000 mph is how fast the 820-lb Deep Impact probe slammed into the nucleus of comet Tempel 1 on July 4. The flyby spacecraft observed a plume of talcum-power-sized dust blasted from the comet’s surface; three cameras took approximately 4,500 images during the encounter. Surface details of 4 meters in diameter are nearly a factor of 10 better than any collected in previous comet missions. NASA www.nasa.gov/mission_pages/deepimpact/main/index.html
