On 15 August 1977, volunteer Jerry Ehman circled an anomalous radio signal on a printout at Ohio State University and scrawled “Wow!” in the margin. That 72-second transmission, detected at the hydrogen frequency from the direction of Sagittarius, remains the most compelling candidate signal in the history of SETI. It has never been heard again. On the same date in 2013, the Smithsonian announced the olinguito, the first new carnivorous mammal identified in the Americas in 35 years. A teddy bear sized creature from the Andean cloud forests, it had been mistaken for its cousin, the olingo, for over a century. In 1995, Shannon Faulkner became the first female cadet to matriculate at The Citadel after a bruising two year legal battle. She withdrew within a week, but the door she forced open stayed open. And in 2015, North Korea marked Liberation Day by creating Pyongyang Standard Time, shifting its clocks 30 minutes out of step with the rest of the world. The experiment lasted three years. A day of signals, species, barriers, and bureaucratic timekeeping.
