Dam Good Luck: From the beginning, Las Vegas was built to serve travelers. The railroad needed a way station, and Las Vegas was the place. Growth continued for ten years, and by 1915 the town had telephones, round-the-clock electricity, and a growing population — many of whom worked in the railroad repair shop. But such heady progress would soon come to a halt. The growing competition in rail transport resulted in Union Pacific buying the Los Angeles–Salt Lake line. Union Pacific then consolidated its operations, eliminating the Las Vegas repair facility. Additionally, Las Vegas had been made a part of Nevada's new Clark County in 1909, a year when the legislature also outlawed gambling. These unfortunate circumstances threatened to relegate Las Vegas to the status of a small desert community that could no longer support its 3000 residents. But the southwest's growing need for water, combined with Las Vegas's fortuitous proximity to the Colorado River, would give Las Vegas a second chance to achieve prosperity. Construction on Hoover Dam (originally Boulder Dam, subsequently renamed for the president who authorized the project) began in 1931 in a canyon 45 miles (72 km) southeast of Las Vegas. Providing an influx of $165 million to the southwestern economy, Hoover Dam played a major role in preventing Las Vegas from drying up, both financially and literally. Not only did it create jobs, but it also created Lake Mead, the massive reservoir that today provides water to all of southern Nevada. More Government Help: The construction of Hoover Dam did not single-handedly save Las Vegas, however. The state legislature helped as well, by legalizing gambling in 1931 and thus solidifying the future of the town, though legislators and residents could never have known this at the time. The hordes of people who attended Hoover Dam's 1935 dedication set the city's now-formidable public relations machine into action. They went to work on what has become one of the lengthiest citywide tourism campaigns ever attempted. It didn't take long for the city to establish itself as a wild-West town with an "anything goes" attitude. Vices outlawed or heavily controlled elsewhere were legal here, available any hour of any day (or night).

Electric charge is a physical property. It occurs between particles or objects. It causes them to attract or repel each other. They do not even have to touch. This is unlike the typical push or pull you may be familiar with. All electric charge is based on the protons and electrons in atoms. A proton has a positive electric charge. An electron has a negative electric charge. Forces on Charged Objects Most atoms are balanced electrically. They have the same number of positive and negative charges. Therefore, the number of protons equals the number of electrons. Neutrons do not matter as they have no charge. When an object loses some electrons, it becomes positively charged. There are now more protons than electrons inside the atom. The lost electrons may remain free. Or, they may attach to another object. The new object now has more electrons than protons. It then becomes negatively charged. 

Question: "What causes objects to attract or repel each other?"

Response: "Protons and electrons"

You will remember the name of Garibaldi, the Italian patriot, who with Mazzini had been stirring up trouble for the Austrians. They finally pursued him so closely that he had to leave Italy. He came to America and set up a fruit store in New York City, where there were quite a number of his countrymen. By 1854, he had made a great deal of money in the fruit business, but had not forgotten his beloved country, and was anxious to be rich only in order that he might free Italy from the Austrians. He sold out his business in New York, and taking all his money, sailed for Italy. When the war of 1859 broke out, he volunteered, and fought throughout the campaign. But the compromising terms of peace galled him, and he was not satisfied with a country only half free. In the region around Genoa, he enrolled a thousand men to go on what looked like a desperate enterprise. Garibaldi had talked with Cavour, and between them, they had schemed to overthrow the kingdom of the Two Sicilies and join this land to the northern country. Of course, Cavour pretended not to know anything about Garibaldi, for the king of Naples and Sicily was supposed to be a friend of the king of Sardinia. Nevertheless, he secretly gave Garibaldi all the help that he dared, and urged men to enroll with him.
