Created in 1777, during the American Revolution the arsenal stored muskets, cannon, and other weapons. When France entered the war on the side of the United States, the large stores of arms and ammunition were sent to Springfield for storage and to be sent to the troops. After the war there were large supplies of Charleville muskets stored at Springfield. When the US decided to manufacture its own muskets, Springfield had a daunting task ahead of it. The government had to start up arms factories with no past experience in doing so. When Whitney was awarded the contract (for five years) he was paid most of the money up front. The contract paid Whitney $13.40 per musket when it was determined the Springfield armory could make them for $10 each. The reason they did this was to learn from Whitney and other contractors how the weapon was produced and assembled efficiently. When government inspectors saw talented workers at various contractor's factories, they would often persuade them to come work at Springfield. By the 1840s the government no longer saw the need to pay contractors the higher prices and would award contracts based on the best bid.

RPK machine gun
The RPK is a Soviet machine gun that was designed by Mikhail Kalashnikov. The RPK is a replacement of the older RPD. The RPK production began in 1961 and ended in 1978. The RPK-74 began in 1974 replacing the older RPK. The RPK was based on the AK-47. The RPK was used by the NVA and Viet Congs in the Vietnam War.
South Italy
South Italy ( or just ) is one of the five official statistical regions of Italy used by the National Institute of Statistics (ISTAT), a NUTS1 level region.
South Italy is defined only for statistical and for some elections. It should not to be confused with the "Mezzogiorno", or Southern Italy, which generally refers to all the southern half of the Italian State, including the island of Sicily and sometimes even Sardinia. The two islands form a distinct statistical region.region.
South Italy borders to the north with Central Italy (to the northwest with Lazio and to the northeast with Marche). The Adriatic Sea is to the east and the Tyrrhenian Sea to the west, and the Ionian Sea to the south.
The Apennines are mountain ranges that goes from north to south through South Italy. The highest point in the region is the Corno Grande () (part of the Gran Sasso) that is high.
Central Italy encompasses six of the 20 regions of Italy, including 24 provinces and 1,789 comuniː
The "comuni" with more than 100,000 persons living in them areː

Laws of motion
In physics, a number of noted theories of the motion of objects have developed. Among the best-known are:
Interchangeable parts
Interchangeable parts is a basic concept of creating identical or nearly identical parts to be mass produced. These parts can then be put together to form a product. For example, cars, computers, furniture, almost all products used today, are made from interchangeable parts. These parts are made with precision machines so each part can fit in any product that uses this part. Since it is no longer necessary to make each part one at a time and by hand, assembling products takes fewer workers. This lowers the cost of the product. Interchangeability of parts also allows products to be repaired by replacing a broken part with an identical new part. Eli Whitney was the first to use interchangeable parts in manufacturing.
Several inventors have had the idea of interchangeable parts in the past. But their version of the idea revolved around parts that had very loose tolerances or were used only for very simple parts. In 1720 a Swedish inventor named Christopher Polhem used interchangeable parts for clocks in his workshop. But the idea was not used outside his shops.
About the middle of the 18th century, French gunsmith Honoré Blanc developed the concept of interchangeable parts for muskets. Blanc tried to interest other European gunsmiths, but they were not impressed by the idea. But he did interest the American Ambassador to France, Thomas Jefferson. Jefferson quickly saw that mass production of weapons parts would free America from dependence on European sources for parts. He could not get Blanc to move to the United States but he did convince President George Washington it was a good idea. It came at a critical time when Congress was preparing for a war with France. In 1798, Eli Whitney got the first contract for 10,000 muskets to be delivered within two years. Whitney used a large force of unskilled workers and machinery to produce standardized identical parts at a low cost. What he produced was the first smoothbore flintlock musket produced in the United States, the Springfield Model 1795 Musket. Whitney's idea of using machines to create interchangeable parts started what came to be known as the "American system" of mass production.
The concept of mass production depends on the use of interchangeable parts. One of the most famous inventors to use interchangeable parts, mass production and the assembly line was Henry Ford. Unlike other cars of the time, his Ford Model T used the same identical parts in each vehicle. Parts were created in large quantities and delivered to his assembly plant where workers built the cars on an assembly line. This allowed Ford to produce a quality vehicle ready to go in just 93 minutes. Ford raised workers' wages in 1914 to $5 a day. That was an excellent wage at the time, so much so that it allowed many of his workers to buy their own Model T. That same year Ford produced more cars than all other car manufacturers combined. His least expensive model in 1914, the Runabout, sold for $440. By 1925 he was able to sell a Model T for as little as $260.
Social media in the 2016 United States presidential election
In 2016, social media had the biggest effect ever on the United States presidential election. For the first time, social media created the change (of plans for Democratic and Republican primaries) rather than talking about it. Many journalists expected this.
Many presidential candidates benefited from the use of social media in the 2016 election.
Many people think social media is the reason Bernie Sanders did so well in the Democratic primaries. In May 2016, 450,000 people belonged to the pro-Sanders Facebook group "Bernie Sanders' Dank Meme Stash". Another pro-Sanders group, "Bernie or Hillary?", exists.
