Electronics Get The Blood Flowing At Rock Shows And In Hospital Beds
By Larry Nicholson, President, Applied Sciences Inc.

I was constantly inventing things as a child, especially electronic things. Without my parents’ permission, I took apart a transistor radio and built a “rain alert” that turned on a light if it started raining. Much to my displeasure, though, I wasn’t as successful with the robot I built to vacuum my room - it never quite worked!

NASA Blames Software Glitch For Mars Global Surveyor Failure
By Richard Gawel, Managing Editor

After nine years and 52 days, the Mars Global Surveyor orbiter broadcast its last communication with Earth on Nov. 2, 2006. Eleven hours later, depleted batteries left the spacecraft unable to control its orientation. Now, an internal NASA review of the mission has determined why those batteries failed.
