Located just 14 miles northwest of Philadelphia, Bridgeport is a stone's throw from Valley Forge National Historic Park. Incorporated in 1851, the tiny village of 422 acres had 500 residents living within its boundaries. In 1723, Swedish and Welsh immigrants settled along the Schuylkill River, with the Eastburn and Holstein families among the first to settle. Irish immigrants found work in Bridgeport as early as 1860, and Italian immigrants poured into Bridgeport in the 1890s, finding work in the quarries and along the railroads and canals. Through vintage photographs, Bridgeport celebrates the families and industries that have helped shape this borough.

The Future of Energy: Earth, Wind and Fire by the Editors of Scientific American Since the Industrial Revolution our civilization has depended on fossil fuels to generate energy – first it was coal; then petroleum. But there are two problems: the first is that petroleum isn't an infinite resource; and the second is that burning coal and oil puts billions of tons of carbon dioxide into the atmosphere, trapping heat. Temperatures have risen by about 0.6 degrees Celsius over the last 100 years, which may not sound like much, but even that small increase is showing some large effects. For one, records have been set for the seasonal loss of arctic ice. If business as usual continues, we are loo...
