Ohio derives its name from the Ohio River that forms its southern border, which, in turn, originated from the Seneca word ohiːyo', meaning "good river", "great river", or "large creek". The state was home to several ancient indigenous civilizations, with humans present as early as 10,000 BCE. It arose from the lands west of the Appalachian Mountains that were contested by various native tribes and European colonists from the 17th century through the Northwest Indian Wars of the late 18th century. Ohio was partitioned from the Northwest Territory, the first frontier of the new United States, becoming the 17th state admitted to the Union on March 1, 1803, and the first under the Northwest Ordinance. It was the first post-colonial free state admitted to the union and became one of the earliest and most influential industrial powerhouses during the 20th century. Although it has transitioned to a more information- and service-based economy in the 21st century, it remains an industrial state, ranking seventh in GDP , with the third-largest manufacturing sector and second-largest automobile production.

Cleveland, the second most populous city in the U.S. state of Ohio, has 142 completed high-rises, 36of which stand taller than 250 feet (76m). The tallest building in Cleveland is the 57-storyKey Tower, which rises 947 feet (289m) on Public Square. The tower has been the tallest building in Ohio since its completion, in 1991; it also was the tallest building in the United States between Chicago and New York City before the completion, in 2007, of the Comcast Center in Philadelphia. The Terminal Tower, 771 feet (235m), is the second tallest building in Cleveland and Ohio; at the time of its completion, in 1927, the building was the tallest in the world outside New York City.
The history of skyscrapers in Cleveland began in 1889, with the construction of the Society for Savings Building, often called the first skyscraper in the city. Cleveland went through an early building boom in the late 1920s and the early 1930s, during which several high-rise buildings, including the Terminal Tower, were constructed. The city experienced a second, much larger building boom from the early 1970s to the early 1990s, during which it saw the construction of over 15skyscrapers, including the Key Tower and 200 Public Square. Overall, the city is the site of three of the four Ohio skyscrapers that rise at least 656 feet (200m) in height; Cincinnati has the other. In 2020, the skyline of Cleveland was 27th in the United States and 96th in the world, ranked by buildings at least 330 feet (100m) tall, with 18.
Unlike many other big American cities, Cleveland had few skyscraper construction projects in the 2000s. Such projects increased in the 2010s. Skyscrapers completed during this time [which time?] include the Ernst & Young Tower (2013), which is 330 feet (100m) tall, and the Hilton Cleveland Downtown Hotel, which opened in 2016 and is 374 feet (114m) tall. The newest additions to the Cleveland skyline include the 29-story, 350-foot-tall (110m) Beacon apartment building, on Euclid Avenue; the 34-story, 396-foot-tall (121m) Lumen Tower, at Playhouse Square; and the 24-story, 267-foot-tall (81m) Artisan apartment building, in the University Circle district. Notable buildings under construction are the 39-story, 616-foot-tall (188m) Sherwin-Williams global headquarters, and the 23-floor, 250-foot-tall (76m) City Club Apartments downtown.

As Cleveland emerged as a major manufacturing center, the river became heavily affected by industrial pollution, so much so that it caught fire at least 14 times. When it did so on June 22, 1969, news coverage of the event helped to spur the American environmental movement. Since then, the river has been extensively cleaned up through the efforts of Cleveland's city government and the Ohio Environmental Protection Agency (OEPA). In 2019, the American Rivers conservation association named the Cuyahoga "River of the Year" in honor of "50 years of environmental resurgence". (Full article...)
Ovshinsky opened the scientific field of amorphous and disordered materials in the course of his research in the 1940s and 50s in neurophysiology, neural disease, the nature of intelligence in mammals and machines, and cybernetics. Amorphous siliconsemiconductors have become the basis of many technologies and industries. Ovshinsky is also distinguished in being self-taught, without formal college or graduate training. Throughout his life, his love for science and his social convictions were the primary engines for his inventive work. (Full article...)
