You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone. • • Listen on Google Assistant through Extra Audio: • https://assistant.google.com/services... • Other Wikipedia audio articles at: • https://www.youtube.com/results?searc... • Upload your own Wikipedia articles through: • https://github.com/nodef/wikipedia-tts • Speaking Rate: 0.7889776622765166 • Voice name: en-AU-Wavenet-D • • • I cannot teach anybody anything, I can only make them think. • Socrates • • • SUMMARY • ======= • Street lighting in the United States was introduced to the US by inventor Benjamin Franklin, who was the postmaster of Philadelphia, Pennsylvania. For this reason, many regard Philadelphia as the birthplace of street lighting in the US. • The colonial-era streetlights were lit by candles placed inside a glass vessel, which kept the candle from being blown out by wind. Franklin's design was four-sided, with four separate panes of glass, so that if one pane of glass was broken, the lamp did not need to be entirely replaced, and might not even blow out. • After the invention of gas lighting by William Murdoch in 1792, cities in Britain began to light their streets using gas. The United States followed suit shortly afterwards with the introduction of gas lighting to Pelham Street in Newport, Rhode Island in 1803. Throughout the 19th century, the use of gas lighting increased. Some locations in the US still use gas lights. • After Thomas Edison pioneered electric use, light bulbs were developed for the streetlights as well. The first city to use electric street lights was Wabash, Indiana. Charles F. Brush of Cleveland, Ohio wanted to publicly test his new invention the Brush Light and needed a city to do so. The City Council of Wabash agreed to testing the lights and on March 31, 1880, Wabash became the First Electrically Lighted City in the World as a flood of light engulfed the town from four Brush Lights mounted atop the courthouse. One of the original Brush Lights is on display at the Wabash County Courthouse. By the beginning of the 20th century, the number of fire-based streetlights was dwindling as developers were searching for safer and more effective ways to illuminate their streets. Fluorescent and incandescent lights became popular during the 1930s and 1940s, when automobile travel began to flourish. A street with lights was referred to as a white way during the early 20th century. Part of New York City's Broadway was nicknamed the Great White Way due to the massive number of electric lights used on theater marquees lining the street.
