By some estimates, anywhere from 3%-7% of school-aged children have attention-deficit hyperactivity disorder (ADHD). The percentage is much more severe in comedians and movie stars (by my estimate of their self proclaimed diagnosis on late night TV shows). Which explains the need for gadgets such as “The Attention-Getter” a toy looking stopwatch that emits loud and funny sounds to get the attention of students.

Gordon Moore, co-founder of Intel Corp., is well known for making the prediction in 1965 that the number of transistors on a computer chip would double every two years. Early in 2008, Intel announced a record 2 Billion transistors in 1 chip.  With each new chip density record the problems of crosstalk and logic gate current leakage become more troublesome to solve. The answer may be:  Noise.
