180 Years of Scientific American Means 180-Degree Turns in Science—Here Are Some of the Wildest Ones
Science doesn’t move in straight lines—it doubles back, rethinks, and surprises us. As Scientific American celebrates 180 years, the magazine highlights moments when accepted truths flipped on their heads: nerves once thought irreparable shown to heal, plastic born as a “green” alternative to ivory, and Martian “canals” revealed as an optical illusion. These U-turns remind us that knowledge is provisional, built on curiosity and correction. It’s a fitting reflection for a publication that has been chronicling discovery since 1845.
