Expo 74
Expo '74, officially known as the International Exposition on the Environment, Spokane 1974, was a world's fair held May 4, 1974, to November 3, 1974 in Spokane, Washington in the northwest United States. It was the first environmentally themed world's fair and attended by roughly 5.6 million people. The heart of the fair park grounds was located on Canada Island, Havermale Island, and the adjacent south bank of the Spokane River, comprising present-day Riverfront Park, in the center of the city. With the exception of two pavilions, all of the major buildings were modular structures assembled on the site. The fair had 5.6 million visitors and was considered a success, nearly breaking even, revitalizing the blighted urban core, and pumping an estimated $150 million into the local economy and surrounding region. In proclaiming itself the first exposition on an environmental theme, Expo '74 distanced itself from the more techno-centric world's fairs of the 1960s. The environment ...

Möbius Strip
In mathematics, a Möbius strip, Möbius band, or Möbius loop is a surface that can be formed by attaching the ends of a strip of paper together with a half-twist. As a mathematical object, it was discovered by Johann Benedict Listing and August Ferdinand Möbius in 1858, but it had already appeared in Roman mosaics from the third century CE. The Möbius strip is a non-orientable surface, meaning that within it one cannot consistently distinguish clockwise from counterclockwise turns. Every non-orientable surface contains a Möbius strip. As an abstract topological space, the Möbius strip can be embedded into three-dimensional Euclidean space in many different ways: a clockwise half-twist is different from a counterclockwise half-twist, and it can also be embedded with odd numbers of twists greater than one, or with a knotted centerline. Any two embeddings with the same knot for the centerline and the same number and direction of twists are topologically equivalent. All o ...

Northwestern United States
The Northwestern United States, also known as the American Northwest or simply the Northwest, is an informal geographic region of the United States. The region consistently includes the states of Oregon, Washington, Idaho, Montana and Wyoming. Some sources include Southeast Alaska in the Northwest. The related but distinct term "Pacific Northwest" generally excludes areas from the Rockies eastward, whereas the term " Inland Northwest" excludes areas east of the Cascades. The Northwestern United States is a subportion of the Western United States (which is, itself, even more ambiguous). In contrast, states included in the neighboring regions (Southwestern United States and Great Plains) and Utah are not simultaneously considered part of both regions. Like the southwestern United States, the Northwest definition has moved westward over time. The current area includes the old Oregon Territory (created in 1848–Oregon, Washington, Idaho, and areas in Montana west of the Conti ...

Great Wall Of China
The Great Wall of China (, literally "ten thousand ''li'' wall") is a series of fortifications that were built across the historical northern borders of ancient Chinese states and Imperial China as protection against various nomadic groups from the Eurasian Steppe. Several walls were built from as early as the 7th century BC, with selective stretches later joined by Qin Shi Huang (220–206 BC), the first emperor of China. Little of the Qin wall remains. Later on, many successive dynasties built and maintained multiple stretches of border walls. The best-known sections of the wall were built by the Ming dynasty (1368–1644). Apart from defense, other purposes of the Great Wall have included border controls, allowing the imposition of duties on goods transported along the Silk Road, regulation or encouragement of trade and the control of immigration and emigration. Furthermore, the defensive characteristics of the Great Wall were enhanced by the construction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oregon Railroad And Navigation Company
The Oregon Railroad and Navigation Company (OR&N) was a railroad that operated a rail network of running east from Portland, Oregon, United States, to northeastern Oregon, northeastern Washington, and northern Idaho. It operated from 1896 as a consolidation of several smaller railroads. OR&N was initially operated as an independent carrier, but Union Pacific (UP) purchased a majority stake in the line in 1898. It became a subsidiary of UP titled the Oregon–Washington Railroad and Navigation Company in 1910. In 1936, Union Pacific formally absorbed the system, which became UP's gateway to the Pacific Northwest. Predecessors The OR&N was made up of several railroads: * Columbia Southern Railway from Biggs to Shaniko, Oregon. *Oregon ''Railway'' and Navigation Company traces its roots back as far as 1860. It was incorporated in 1879 in Portland, Oregon and operated between Portland and eastern Washington and Oregon until 1896, when it was reorganized into the Oregon ''Railroad ...

Olmsted Brothers
The Olmsted Brothers company was a landscape architectural firm in the United States, established in 1898 by brothers John Charles Olmsted (1852–1920) and Frederick Law Olmsted Jr. (1870–1957), sons of the landscape architect Frederick Law Olmsted. History The Olmsted Brothers inherited the nation's first landscape architecture business from their father Frederick Law Olmsted. This firm was a successor to the earlier firm of Olmsted, Olmsted and Eliot after the death of their partner Charles Eliot in 1897. The two brothers were among the founding members of the American Society of Landscape Architects (ASLA) and played an influential role in creating the National Park Service. Prior to their takeover of the firm, Frederick Law Olmsted Jr. had worked as an apprentice under his father, helping to design projects such as Biltmore Estate and the World's Columbian Exposition before graduating from Harvard University. The firm employed nearly 60 staff at its peak in the early 1930 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydropower
Hydropower (from el, ὕδωρ, "water"), also known as water power, is the use of falling or fast-running water to produce electricity or to power machines. This is achieved by converting the gravitational potential or kinetic energy of a water source to produce power. Hydropower is a method of sustainable energy production. Hydropower is now used principally for hydroelectric power generation, and is also applied as one half of an energy storage system known as pumped-storage hydroelectricity. Hydropower is an attractive alternative to fossil fuels as it does not directly produce carbon dioxide or other atmospheric pollutants and it provides a relatively consistent source of power. Nonetheless, it has economic, sociological, and environmental downsides and requires a sufficiently energetic source of water, such as a river or elevated lake. International institutions such as the World Bank view hydropower as a low-carbon means for economic development. Since ancient t ...

Waterfall
A waterfall is a point in a river or stream where water flows over a vertical drop or a series of steep drops. Waterfalls also occur where meltwater drops over the edge of a tabular iceberg or ice shelf. Waterfalls can be formed in several ways, but the most common method of formation is that a river courses over a top layer of resistant bedrock before falling on to softer rock, which erodes faster, leading to an increasingly high fall. Waterfalls have been studied for their impact on species living in and around them. Humans have had a distinct relationship with waterfalls for years, travelling to see them, exploring and naming them. They can present formidable barriers to navigation along rivers. Waterfalls are religious sites in many cultures. Since the 18th century they have received increased attention as tourist destinations, sources of hydropower, andparticularly since the mid-20th centuryas subjects of research. Definition and terminology A waterfall is genera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spokane Falls
Spokane Falls is the name of a waterfall and dam on the Spokane River, located in the central business district in downtown Spokane, Washington. The city of Spokane was also initially named "Spokane Falls". History The Native American name for the Spokane Falls was "Stluputqu", meaning "swift water". The falls was once the site of a large Spokane people village. Features The falls consists of an Upper Falls and a Lower Falls. The area around the falls was formerly a rail yard, that was converted to a city park for use as the fairgrounds for the 1974 World's Fair. The park is located predominantly on Havermale Island, the east-most boundary is established by the first fork in the river. This is the site of the Upper Falls Dam, a diversion dam constructed in 1920 that directs the water into the Upper Falls intake on the south channel of the Spokane River. The Upper Falls Power Plant incorporates a Francis turbine capable of generating 10 MW. The water not diverted to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
