The Incandescent Light Bulb

Now the iconic symbol for an idea, the electric incandescent light bulb was independently produced in the late 1870s by Joseph Swan and Thomas Edison—and perhaps earlier by others. However, Edison has received the major credit for this invention because he also developed the power lines and other equipment needed for a lighting system. Financed by the likes of J.P. Morgan and the Vanderbilts, Edison achieved success using a carbon filament in his design. How do incandescent light bulbs work? More...

Evangelista Torricelli (1608)

Dahlonega Gold Rush Days (2016)

Gold Rush Days are a celebratory reminder in Dahlonega, Georgia, of the town's heyday as a gold-rush town. The nation's first major gold rush was here in 1828, and the area around Dahlonega boomed—a federal mint built in 1838 operated for 23 years and coined more than $6 million. Mining continued into the beginning of the 20th century, and today visitors can pan for gold at several locations. The name of the town is derived from the Cherokee name Talonega, meaning "golden." The festival includes arts and crafts exhibits, country cooking, and hog-calling contests. More...
