Walther Bothe

Walther Wilhelm Georg Bothe (8 January 1891 – 8 February 1957) was a German nuclear physicist, who shared the Nobel Prize in Physics in 1954 with Max Born.

In 1913, he joined the newly created Laboratory for Radioactivity at the Reich Physical and Technical Institute (PTR), where he remained until 1930, the latter few years as the director of the laboratory. He served in the military during World War I from 1914, and he was a prisoner of war of the Russians, returning to Germany in 1920. Upon his return to the laboratory, he developed and applied coincidence methods to the study of nuclear reactions, the Compton effect, cosmic rays, and the wave-particle duality of radiation, for which he would receive the Nobel Prize in Physics in 1954.

In 1930 he became a full professor and director of the physics department at the University of Giessen. In 1932, he became director of the Physical and Radiological Institute at the University of Heidelberg. He was driven out of this position by elements of the deutsche Physik movement. To preclude his emigration from Germany, he was appointed director of the Physics Institute of the Kaiser Wilhelm Institute for Medical Research (KWImF) in Heidelberg. There, he built the first operational cyclotron in Germany. Furthermore, he became a principal in the German nuclear energy project, also known as the Uranium Club, which was started in 1939 under the supervision of the Army Ordnance Office.

Walther PPS

The Walther PPS (Polizei-Pistole Schmal / Police Pistol Slim) is a semi-automatic pistol developed by the German company Carl Walther GmbH Sportwaffen of Ulm for concealed carry for civilians and plainclothes law enforcement personnel. It is available in either 9×19mm Parabellum or .40 S&W chamberings. It was first shown in 2007 at the IWA & OutdoorClassics and is a slim polymer framed weapon of similar size to the Walther PPK pistol. The PPS is however technically much more based on the Walther P99 pistol.

PPS pistols manufactured by Walther in Ulm, Germany are imported to the United States through Walther Arms. The PPS pistols are also made under license in Poland by Fabryka Broni Radom.

Design details

Operating mechanism

The Walther PPS is a short recoil-operated locked breech semi-automatic pistol that uses a modified Browning cam-lock system adapted from the Hi-Power pistol. The PPS has a glassfiber-reinforced polymer frame and steel slide assembly. It can be broken down into its main parts or field stripped with a take down catch without the help of tools.

Colt Python

The Colt Python is a .357 Magnum caliber revolver formerly manufactured by Colt's Manufacturing Company of Hartford, Connecticut. It is sometimes referred to as a "Combat Magnum". It was first introduced in 1955, the same year as Smith & Wesson's M29 .44 Magnum. The now discontinued Colt Python targeted the premium revolver market segment. Some firearm collectors and writers such as Jeff Cooper, Ian V. Hogg, Chuck Hawks, Leroy Thompson, Scott Wolber, Renee Smeets and Martin Dougherty have described the Python as the finest production revolver ever made.

Description

The Colt Python is a double action handgun chambered for the .357 Magnum cartridge, built on Colt's large I-frame. Pythons have a reputation for accuracy, smooth trigger pull, and a tight cylinder lock-up. They are similar in size and function to the Colt Trooper and Colt Lawman revolvers.

History

The Colt Python was first introduced in 1955 as Colt's top-of-the-line model and was originally intended to be a large-frame 38 Special target revolver. As a result, it features precision adjustable sights, a smooth trigger, solid construction, and extra metal. Pythons have a distinct appearance due to a full barrel underlug, ventilated rib and adjustable sights. Originally, Colt manufactured Pythons with hollow underlugs but left them solid to work as a stabilizing barrel weight. When the revolver is at full cock, just as the trigger is pressed, the cylinder locks up for the duration of the hammer strike. Other revolvers have a hint of looseness even at full-cock. The gap between the cylinder and forcing cone is very tight, further aiding accuracy and velocity. Starting in the 1970s each Python revolver was boresighted at the factory with a laser and was the first mass-produced revolver to do so.

New Orleans

New Orleans (/nuː ˈɔːrlɪnz/,/nuː ˈɔːrliənz/, /nuː ɔːrˈliːnz/, or /ˈnɔːrlənz/; French: La Nouvelle-Orléans [la nuvɛlɔʁleɑ̃]) is a major United States port and the largest city and the center of the metropolitan area in the state of Louisiana. The population of the city was 343,829 as of the 2010 U.S. Census. The New Orleans metropolitan area (New Orleans–Metairie–Kenner Metropolitan Statistical Area) had a population of 1,167,764 in 2010 and was the 46th largest in the United States. The New Orleans–Metairie–Bogalusa Combined Statistical Area, a larger trading area, had a 2010 population of 1,452,502.

The city is named after the Duke of Orleans, who reigned as Regent for Louis XV from 1715 to 1723, as it was established by French colonists and strongly influenced by their European culture. It is well known for its distinct French and Spanish Creole architecture, as well as its cross-cultural and multilingual heritage. New Orleans is also famous for its cuisine, music (particularly as the birthplace of jazz), and its annual celebrations and festivals, most notably Mardi Gras, dating to French colonial times. The city is often referred to as the "most unique" in the United States.
