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, 36 of which stand taller than 250 feet (76 m). The tallest building in Cleveland is the 57-storyKey Tower, which rises 947 feet (289 m) 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 (235 m), 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 15 skyscrapers, 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 (200 m) 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 (100 m) 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 (100 m) tall, and the Hilton Cleveland Downtown Hotel, which opened in 2016 and is 374 feet (114 m) tall. The newest additions to the Cleveland skyline include the 29-story, 350-foot-tall (110 m) Beacon apartment building, on Euclid Avenue; the 34-story, 396-foot-tall (121 m) Lumen Tower, at Playhouse Square; and the 24-story, 267-foot-tall (81 m) Artisan apartment building, in the University Circle district. Notable buildings under construction are the 39-story, 616-foot-tall (188 m) Sherwin-Williams global headquarters, and the 23-floor, 250-foot-tall (76 m) City Club Apartments downtown.

Buildings at Unit III, seen in 2012
The Dayton Project was a research and development project to produce polonium during World War II, as part of the larger Manhattan Project to build the first atomic bombs. Work took place at several sites in and around Dayton, Ohio. Those working on the project were ultimately responsible for creating the polonium-based modulated neutron initiators that were used to begin the chain reactions in the atomic bombs.
The Dayton Project began in 1943 when Monsanto's Charles Allen Thomas was recruited by the Manhattan Project to coordinate the plutonium purification and production work being carried out at various sites. Scientists at the Los Alamos Laboratory calculated that a plutonium bomb would require a neutron initiator. The best-known neutron sources used radioactive polonium and beryllium, so Thomas undertook to produce polonium at Monsanto's laboratories in Dayton. While most Manhattan Project activity took place at remote locations, the Dayton Project was located in a populated, urban area. It ran from 1943 to 1949, when the Mound Laboratories were completed in nearby Miamisburg, Ohio, and the work moved there.
The franchise struggled in their initial years, failing to win 30 games in a season until 2005–06. The team qualified for the Stanley Cup playoffs for the first time in 2009, but were swept by the Detroit Red Wings. Columbus ultimately notched their first playoff game victory in the 2014 playoffs, and won their first playoff series in the 2019 playoffs against the Tampa Bay Lightning, becoming the first team in NHL history to sweep a Presidents' Trophy winner in the first round. Along with the Seattle Kraken, the Blue Jackets are one of only two teams in the league who have yet to appear in the conference finals. (Full article...)
