paragraph_text: GE's history of working with turbines in the power-generation field gave them the engineering know-how to move into the new field of aircraft turbosuperchargers.[citation needed] Led by Sanford Alexander Moss, GE introduced the first superchargers during World War I, and continued to develop them during the Interwar period. Superchargers became indispensable in the years immediately prior to World War II, and GE was the world leader in exhaust-driven supercharging when the war started. This experience, in turn, made GE a natural selection to develop the Whittle W.1 jet engine that was demonstrated in the United States in 1941. GE ranked ninth among United States corporations in the value of wartime production contracts. Although their early work with Whittle's designs was later handed to Allison Engine Company, GE Aviation emerged as one of the world's largest engine manufacturers, second only to the British company, Rolls-Royce plc.

paragraph_text: The fictional universe of British author J.K. Rowling's Harry Potter series of fantasy novels comprises two distinct societies: the Wizarding World and the Muggle world. In the novels, the Muggle world is the world inhabited by the non-magical majority, with which the Wizarding world exists coextensively, albeit mostly remaining hidden from the non-magical humans. The plot of the series is set in 1990s Britain, but in a veiled and separate shadow society wherein magic is commonly used and practised, and those who can use it live in self - enforced seclusion, hiding their abilities from the rest of the world. The term ``Wizarding World ''refers to the global wizard community that lives hidden in parallel with the Muggle world; the different terms refer to different communities within the same area rather than separate planets or worlds. Any new works taking place in this universe are released under the`` J.K. Rowling's Wizarding World'' brand.

paragraph_text: Widespread segregation in 19th- and early 20th-century North America made it difficult for African-Americans to join Lodges outside of Prince Hall jurisdictions – and impossible for inter-jurisdiction recognition between the parallel U.S. Masonic authorities. By the 1980s, such discrimination was a thing of the past, and today most U.S. Grand Lodges recognise their Prince Hall counterparts, and the authorities of both traditions are working towards full recognition. The United Grand Lodge of England has no problem with recognising Prince Hall Grand Lodges. While celebrating their heritage as lodges of black Americans, Prince Hall is open to all men regardless of race or religion.

Then in 1820, André - Marie Ampère showed that parallel wires with currents attract one another if the currents are in the same direction and repel if they are in opposite directions. Finally, Jean - Baptiste Biot and Félix Savart discovered the Biot -- Savart law in 1820, which correctly predicts the magnetic field around any current - carrying wire.
