Wow! signal – Wikipedia, the free encyclopedia
The Wow! signal was a strong narrowband radio signal detected by Dr. Jerry R. Ehman on August 15, 1977, while working on a SETI project at the Big Ear radio telescope of The Ohio State University. The signal bore expected hallmarks of potential non-terrestrial and non-solar system origin. It lasted for the full 72-second duration that Big Ear observed it, but has not been detected again. The signal has been the subject of significant media attention.
Amazed at how closely the signal matched the expected signature of an interstellar signal in the antenna used, Ehman circled the signal on the computer printout and wrote the comment “Wow!” on its side. This comment became the name of the signal. -

Never Have Your Dog Stuffed: And Other Things I’ve Learned by Alan Alda
My rating: 3 of 5 stars
Pleasant. Definitely not the book I would take on a desert island, but I can’t say I didn’t like it. Alan Alda is obviously not a writer and his style can get a bit heavy at times. But I enjoyed the way he managed to turn his life into a story. Sharing his childhood experience with an immature father and a crazy mother without an ounce of pathos is definitely a brilliant prowess. Also learned much about the power of theatrical improvisation.
