National Park Service
The National Park Service (NPS) is an agency of the United States federal government within the U.S. Department of the Interior that manages all national parks, most national monuments, and other natural, historical, and recreational properties with various title designations. The U.S. Congress created the agency on August 25, 1916, through the National Park Service Organic Act. It is headquartered in Washington, D.C., within the main headquarters of the Department of the Interior. The NPS employs approximately 20,000 people in 423 individual units covering over 85 million acres in all 50 states, the District of Columbia, and US territories. As of 2019, they had more than 279,000 volunteers. The agency is charged with a dual role of preserving the ecological and historical integrity of the places entrusted to its management while also making them available and accessible for public use and enjoyment.

Idaho
Idaho ( ) is a state in the Pacific Northwest region of the Western United States. To the north, it shares a small portion of the Canada–United States border with the province of British Columbia. It borders the states of Montana and Wyoming to the east, Nevada and Utah to the south, and Washington and Oregon to the west. The state's capital and largest city is Boise. With an area of , Idaho is the 14th largest state by land area, but with a population of approximately 1.8 million, it ranks as the 13th least populous and the 7th least densely populated of the 50 U.S. states. For thousands of years, and prior to European colonization, Idaho has been inhabited by native peoples. In the early 19th century, Idaho was considered part of the Oregon Country, an area of dispute between the U.S. and the British Empire. It officially became U.S. territory with the signing of the Oregon Treaty of 1846, but a separate Idaho Territory was not organized until 1863, instead ...

Hanford, Washington
Hanford was a small agricultural community in Benton County, Washington, United States. It and White Bluffs, Washington, White Bluffs were depopulated in 1943 in order to make room for the nuclear production facility known as the Hanford Site. The town was located in what is now the "100F" sector of the site. The original town, named for the judge and irrigation company president Cornelius H. Hanford, was settled in 1907 on land bought by the local power and water utility. In 1913, the town had a spur railroad link to the transcontinental Chicago, Milwaukee and St. Paul Railway, also known as "the electric railroad". By 1925 the booming town enjoyed high agricultural demand and provided a hotel, bank, and elementary and high schools. The Federal government of the United States, federal government eminent domain, condemned Hanford to make way for the Hanford Site. Residents were given a thirty-day eviction notice on March 9, 1943. Most buildings were razed, with the exception of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Reactor
A nuclear reactor is a device used to initiate and control a fission nuclear chain reaction or nuclear fusion reactions. Nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion. Heat from nuclear fission is passed to a working fluid (water or gas), which in turn runs through steam turbines. These either drive a ship's propellers or turn electrical generators' shafts. Nuclear generated steam in principle can be used for industrial process heat or for district heating. Some reactors are used to produce isotopes for medical and industrial use, or for production of weapons-grade plutonium. , the International Atomic Energy Agency reports there are 422 nuclear power reactors and 223 nuclear research reactors in operation around the world. In the early era of nuclear reactors (1940s), a reactor was known as a nuclear pile or atomic pile (so-called because the graphite moderator blocks of the first reactor were placed into a tall pi ...

Charleston Church Shooting
On June 17, 2015, a mass shooting occurred in Charleston, South Carolina, in which nine African Americans were killed during a Bible study at the Emanuel African Methodist Episcopal Church. Among those people who were killed was the senior pastor, state senator Clementa C. Pinckney. This church is one of the oldest black churches in the United States, and it has long been a center for organizing events which are related to civil rights. The morning after the attack, police arrested Dylann Roof in Shelby, North Carolina; a 21-year-old white supremacist who had attended the Bible study before he committed the shooting. He was found to have targeted members of this church because of its history and status. Roof was found competent to stand trial in federal court. In December 2016, Roof was convicted of 33 federal hate crime and murder charges. On January 10, 2017, he was sentenced to death for those crimes. Roof was separately charged with nine counts of murder in the South C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Modern Display Of The Confederate Battle Flag
Although the Confederate States of America dissolved at the end of the American Civil War (1861–1865), its battle flag continues to receive modern display. The modern display began during the 1948 United States presidential election when it was used by the Dixiecrats, a political party that opposed civil rights for African Americans. Further display of the flag was a response to the civil rights movement and the passage of federal civil rights laws in the 1950s and 1960s. The display of flags associated with the Confederacy is controversial. Supporters associate the Confederate battle flag with pride in Southern heritage, states' rights, and historical commemoration of the Civil War, while opponents associate it with glorification of the Civil War and celebrating the Myth of the Lost Cause, racism, slavery, segregation, white supremacy, historical negationism, and treason. Incidents such as the Charleston church shooting, the Unite the Right rally, and the murder of Georg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unmanned Aerial Vehicle
An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without any human pilot, crew, or passengers on board. UAVs are a component of an unmanned aircraft system (UAS), which includes adding a ground-based controller and a system of communications with the UAV. The flight of UAVs may operate under remote control by a human operator, as remotely-piloted aircraft (RPA), or with various degrees of autonomy, such as autopilot assistance, up to fully autonomous aircraft that have no provision for human intervention. UAVs were originally developed through the twentieth century for military missions too "dull, dirty or dangerous" for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications.Hu, J.; Bhowmick, P.; Jang, I.; Arvin, F.; Lanzon, A.,A Decentralized Cluster Formation Containment Framework for Multirobot Systems IEEE Tr ...

Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing m ...

First Inauguration Of Barack Obama
The first inauguration of Barack Obama as the 44th president of the United States took place on Tuesday, January 20, 2009, at the West Front of the United States Capitol in Washington, D.C. The 56th inauguration, which set a record attendance for any event held in the city, marked the commencement of the first term of Obama as president and Joe Biden as vice president. Based on combined attendance numbers, television viewership, and Internet traffic, it was one of the most-observed events ever by the global audience. "A New Birth of Freedom", a phrase from the Gettysburg Address, served as the inaugural theme to commemorate the 200-year anniversary of the birth year of President Abraham Lincoln. In his speeches to the crowds, Obama referred to ideals expressed by Lincoln about renewal, continuity, and national unity. Obama mentioned these ideals in his speech to stress the need for shared sacrifice and a new sense of responsibility to answer America's challenges at home and abr ...
