In August 1977, Ohio astronomer Jerry Ehman discovered a radio signal so exciting that he wrote “Wow!” in the margin of its computer printout. Arriving from the direction of the constellation Sagittarius, the signal bore all the characteristics of an alien transmission. But despite decades of eager listening, astronomers have never heard it repeated. In this episode of the Futility Closet podcast we’ll review the story of the “Wow! signal,” which remains an intriguing, unexplained anomaly in the search for extraterrestrial intelligence.
We’ll also share some more nuggets from Greg’s database of oddities and puzzle over why a man chooses to drive a long distance at only 15 mph.

Thanks to reader John McKenna for letter from the ancient Greek boy Theon to his father. It’s from the Oxyrhynchus papyri, from the 2nd or 3rd century:
Theon to his father Theon, greeting. It was a fine thing of you not to take me with you to the city! If you won’t take me with you to Alexandria I won’t write you a letter or speak to you or say goodbye to you; and if you go to Alexandria I won’t take your hand nor ever greet you again. That is what will happen if you won’t take me. Mother said to Archelaus, ‘it quite upsets him to be left behind.’ It was good of you to send me presents … on the 12th, the day you sailed. Send me a lyre, I implore you. If you don’t, I won’t eat, I won’t drink; there now!
The item on William and Henry James is from Vincent Barry’s 2007 book Philosophical Thinking About Dying.
