You all learned the answer in high school: if you have a wave, then you can reduce its amplitude or extinguish it by adding a copy if the same signal with the opposite phase.

This has been done to reduce acoustical noise, but it's rather harder to accomplish with light waves. But then, holography is all about interference.

Steve Reich invented minimal music. Steve Jobs just invented the second record company called Apple (the first one being invented by The Beatles - not anywhere as historical as Sun records). Alan Turing invented the Turing Machine - after Conrad Zuse had built a working computer. Al Bell is credited with the telephone. Innovation was patented by the biblical author of Ecclesiastes.

A failure will not appear until a unit has passed final inspection.
