I am retired from the computer world where I worked most recently at the systems administration level. Before that I taught people how to use computers and how to communicate with computer professionals. I have also taught German to Americans, English as a second language to others, and Reading. Before that I was a chemistry lab technician and an electronics technician. I have been interested in electronics and science my entire life and bought my first Apple II system as soon as it came on the market for only $5,000.
Thoughts about SETI and SETI@home
I believe that extraterrestial live exists, has existed long before earth was formed, and will continue to exist long after earth has faded away. To assume that earth has the only intelligent life in the universe takes a larger leap of faith than I can make. Humans will discover it sometime, but I don't know when and how.
We should send a set of radio beacon signals in a pulse with a modified waveform exterior shape (so that it is apparent to anyone listening, searching, or scanning the universe that this is not a natural phenomena/sine wave). Inserting another set of signals inside the pulse would easily make it apparent to an observer that this is not a natural phenomena. The second beacon of the set should simply repeat the signal from the original and be placed several thousand miles away from the original. A set of such repetitive pulses could be followed at a specific (short)interval by almost any other complex electromagnetic signal that research shows could most easily penetrate the background noise of space.
I run SETI@home because the way the program is designed, I feel even my old computer at home can help.
