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.

Cedar Point is a 364-acre (147 ha) amusement park located on a Lake Erie peninsula in Sandusky, Ohio, United States, owned and operated by Six Flags. It opened in 1870 and is considered the second-oldest operating amusement park in the US behind Lake Compounce. Prior to the merger with Six Flags in 2024, Cedar Point served as the "flagship park" of the Cedar Fair amusement park chain and hosted the corporate headquarters. Known as "America's Roller Coast", the park features 17 roller coasters, which ranks third among amusement parks in North America behind sister parks Canada's Wonderland (19) and Six Flags Magic Mountain (20).
Cedar Point's normal operating season runs from early May until Labor Day in September, which is followed by weekend-only operation through Halloween during an annual event known as HalloWeekends. Other amenities and attractions featured within the park include a one-mile-long (1.6 km) beach, an outdoor water park named Cedar Point Shores, an indoor water park named Castaway Bay, two marinas, and an outdoor sports complex called Cedar Point Sports Center.
The park has reached numerous milestones over the years, including one in which Cedar Point became the only amusement park in the world with five roller coasters that exceed 200 feet (61 m) in height – Magnum XL-200, Millennium Force, Valravn, Steel Vengeance, and Top Thrill 2 – as well as the only park with roller coasters in all four height classifications. Cedar Point also received the Golden Ticket Award for "Best Amusement Park in the World" from Amusement Today for sixteen consecutive years from 1997 to 2013. Among seasonal amusement parks in North America, Cedar Point consistently ranks as the second-most visited behind only Canada's Wonderland, with an estimated 3.44 million visitors in 2022. In addition, several of its buildings are listed on the National Register of Historic Places. (Full article...)
The widest point on the Ohio River is just north of downtown Louisville, where it is one mile (1.6 km) wide. Indiana is on the right towards the flood gates, Kentucky on the left, towards the locks. The jetty on the left is the entrance to the Louisville and Portland Canal.
The Ohio River is a 981-mile-long (1,579 km) river in the United States. It is located at the boundary of the Midwestern and Southern United States, flowing in a southwesterly direction from western Pennsylvania to its mouth on the Mississippi River at the southern tip of Illinois. It is the third largest river by discharge volume in the United States and the largest tributary by volume of the north-south flowing Mississippi River, which divides the eastern from western United States. It is also the sixth oldest river on the North American continent. The river flows through or along the border of six states, and its drainage basin includes parts of 14 states. Through its largest tributary, the Tennessee River, the basin includes several states of the southeastern U.S. It is the source of drinking water for five million people.
The river became a primary transportation route for pioneers during the westward expansion of the early U.S. The lower Ohio River just below Louisville was obstructed by rapids known as the Falls of the Ohio where the elevation falls 26 feet (7.9 m) in 2 miles (3.2 km) restricting larger commercial navigation, although in the 18th and early 19th century its three deepest channels could be traversed by a wide variety of craft then in use. In 1830, the Louisville and Portland Canal (now the McAlpine Locks and Dam) bypassed the rapids, allowing even larger commercial and modern navigation from the Forks of the Ohio at Pittsburgh to the Port of New Orleans at the mouth of the Mississippi on the Gulf of Mexico. Since the "canalization" of the river in 1929, the Ohio has not been a natural free-flowing river; today, it is divided into 21 discrete pools or reservoirs by 20 locks and dams for navigation and power generation.

In December 1940, Bacher joined the Radiation Laboratory at MIT, although he did not immediately cease his research at Cornell into the neutron cross section of cadmium. The Radiation Laboratory was organized into two sections, one for incoming radar signals, and one for outgoing radar signals. Bacher was appointed to handle the incoming signals section. Here he gained valuable experience in administration, coordinating not just the efforts of his scientists, but also those of General Electric and RCA. In 1942, Bacher was approached by Robert Oppenheimer to join the Manhattan Project at its new laboratory in Los Alamos, New Mexico. It was at Bacher's insistence that Los Alamos became a civilian rather than a military laboratory. At Los Alamos, Bacher headed the project's P (Physics) Division, and later its G (Gadget) Division. Bacher worked closely with Oppenheimer, and the two men discussed the project's progress on a daily basis. (Full article...)
