First Volume of Oxford English Dictionary Is Published (1884)

Though the first volume, A–Ant, was published in 1884, the first complete edition of the Oxford English Dictionary was not published until 1928. Planned as a 10-year project, the 44-year undertaking resulted in a comprehensive, historical dictionary of English—the longest in the world today. It required more than 800 volunteers to compile material, including one who, it was later learned, turned out to be working from an asylum for the criminally insane. Why was he there? Discuss

William Clark Gable (1901)

Despite having such large ears that some doubted he could become a romantic lead, Gable had a rugged masculinity and lighthearted charm that proved popular with audiences. The actor debuted on Broadway in 1928 and went to Hollywood in 1930. There he starred in Mutiny on the Bounty, Gone with the Wind, and It Happened One Night, for which he won an Academy Award. What tragedy prompted him to give up show business and become a bomber pilot during World War II? Discuss

Tessellations

Tessellations are patterns of carefully juxtaposed, non-overlapping shapes—like the multicolored tiles of a mosaic—that fill a given surface. They have been used throughout history, from ancient architecture to modern art, and are frequently found in the works of M.C. Escher. Regular tessellations, which are highly symmetrical and made up of congruent, regular polygons, can only be formed using equilateral triangles, squares, or hexagons. Where can tessellations be observed in the natural world? Discuss
