Curtiss YP-37
The Curtiss P-37 was an American fighter aircraft made by Curtiss-Wright in 1937 for the US Army Air Corps. A development of the Curtiss P-36 Hawk to use an inline engine instead of the radial engine of the P-36 the fuselage was lengthened and the cockpit moved back. A small number of YP-37 aircraft was built for Air Corps evaluation. The expected top speed was not achieved and the project terminated in favor of the Curtiss P-40. Design and development In early 1937, after realizing the P-36 Hawk was inferior to more modern European designs, the USAAC ordered Curtiss to adapt one P-36 to the new liquid-cooled turbo-supercharged Allison V-1710. The prototype Hawk was fitted with a turbo-supercharged Allison V-1710-11 as the XP-37 (company designation Model 75I). The cockpit was moved back towards the tail to make room for the massive turbo-superchargers, and the engine was cooled by two radiators on either side of the nose. Armament was one M1919 Browning machine gun an ...

Papyrus 37 designated by 𝔓37 (in the Gregory-Aland numbering) is an early copy of the New Testament in Greek. It is a papyrus manuscript of the Gospel of Matthew dating to the 3rd century, sometime around 250-260 CE, due to its affinities with 𝔓53 (dated to 260 CE), The correspondence of Heroninos (dated shortly before or after 260 CE) and a letter by Kopres (P. Greco-Egizi 208, dated 256 CE).Philip W Comfort and David P Barrett. ''The Text of the Earliest New Testament Greek Manuscripts''.

Phosphorus-37
Although phosphorus (15P) has 23 isotopes from 25P to 47P, only 31P is stable; as such, phosphorus is considered a monoisotopic element. The longest-lived radioactive isotopes are 33P with a half-life of 25.34 days and 32P with a half-life of 14.268 days. All others have half-lives of under 2.5 minutes, most under a second. The least stable is 25P with a half-life shorter than 30 nanoseconds.
