Nazi human experimentation Nazi human experimentation was a series of medical experiments on large numbers of prisoners, including children, by Nazi Germany in its concentration camps in the early to mid 1940s, during World War II and the Holocaust. Chief target populations included Romani, Sinti, ethnic Poles, Soviet POWs, disabled Germans, and most prominently of all, Jews from across Europe.

Fischer–Tropsch process The Fischer–Tropsch process is a collection of chemical reactions that converts a mixture of carbon monoxide and hydrogen into liquid hydrocarbons. These reactions occur in the presence of certain metal catalysts, typically at temperatures of 150 - and pressures of one to several tens of atmospheres. The process was first developed by Franz Fischer and Hans Tropsch at the Kaiser-Wilhelm-Institut für Kohlenforschung in Mülheim an der Ruhr, Germany, in 1925.

Focke-Wulf Fw 159 The Focke-Wulf Fw 159 was an experimental German fighter of the 1930s, designed by Kurt Tank which never reached production, as it was considered inferior to the He 112 and Bf 109. It was a heavier variant of the Focke-Wulf Fw 56, with several improvements, such as a retractable landing gear and enclosed cockpit.

Dornier Do 18 The Dornier Do 18 was a development of the Do 16 flying boat. It was developed for the "Luftwaffe", but "Lufthansa" received five aircraft and used these for tests between the Azores and the North American continent in 1936 and on their mail route over the South Atlantic from 1937 to 1939.

Terre Haute prison experiments The Terre Haute prison experiments were conducted by Dr. John C. Cutler in 1943 and 1944 under Dr. John F. Mahoney, the head of the Venereal Disease Research Laboratory of the US Public Health Service, to determine the effectiveness of treatments for sexually transmitted diseases. The test subjects were prisoners at the U.S. Penitentiary in Terre Haute, Indiana. They were given disclosures and consented to the experiments. A total of 241 prisoners participated in the study and received $100, a certificate of merit, and a letter of commendation to the parole board at the end of the study. The researchers deposited various strains and concentrations of gonorrhea into the penises of the test subjects. After several months, Mahoney noted that the method of inducing gonorrhea in humans was unreliable and could not provide meaningful tests of prophylactic agents.

Experimental film Experimental film, experimental cinema or avant-garde cinema is a mode of filmmaking that rigorously re-evaluates cinematic conventions and explores non-narrative forms and alternatives to traditional narratives or methods of working. Many experimental films, particularly early ones, relate to arts in other disciplines: painting, dance, literature and poetry, or arise from research and development of new technical resources.

Thought experiment A thought experiment (German: "Gedankenexperiment" , "Gedanken-Experiment" or "Gedankenerfahrung") considers some hypothesis, theory, or principle for the purpose of thinking through its consequences. Given the structure of the experiment, it may not be possible to perform it, and even if it could be performed, there need not be an intention to perform it.

John Edmund Kerrich John Edmund Kerrich (1903–1985) was a mathematician noted for a series of experiments in probability which he conducted while interned in Nazi-occupied Denmark in the 1940s.

The Design of Experiments The Design of Experiments is a 1935 book by the English statistician Ronald Fisher about the design of experiments and is considered a foundational work in experimental design. Among other contributions, the book introduced the concept of the null hypothesis in the context of the lady tasting tea experiment. A chapter is devoted to the Latin square.

Nachtjagdgruppe 10 "Nachtjagdgruppe" 10 (NJGr 10) was a German Luftwaffe night fighter "gruppe" (group) during World War II. It was formed on 1 January 1944 at Werneuchen with 3 "Staffel" (squadrons). It was subordinated to the 1. "Jagd-Division" (1st fighter division), stationed at Döberitz. On 6 March 1945, NJGr 10 transferred to Liebenwalde and disbanded in April 1945. The remnants of NJGr 10 were absorbed by Nachtjagdgeschwader 5 (5th Night Fighter Wing). Its main task was to explore new and revised tactical deployment of night fighters, test the latest search and detection equipment in conjunction with the test site for radar equipment under combat conditions ("Erprobung von Radarsysteme für die Nachtjagd"), and place the anti-Mosquito effort under a more centralised command.

Bat bomb Bat bombs were an experimental World War II weapon developed by the United States. The bomb consisted of a bomb-shaped casing with over a thousand compartments, each containing a hibernating Mexican free-tailed bat with a small, timed incendiary bomb attached. Dropped from a bomber at dawn, the casings would deploy a parachute in mid-flight and open to release the bats, which would then roost in eaves and attics in a 20–40 mile radius. The incendiaries would start fires in inaccessible places in the largely wood and paper constructions of the Japanese cities that were the weapon's intended target.

Mistel Mistel (German for "mistletoe"), was the larger, unmanned component of a composite aircraft configuration developed in Germany during the later stages of World War II. The composite comprised a small piloted control aircraft mounted above a large explosives-carrying drone, the Mistel, and as a whole was referred to as the Huckepack ("Piggyback"), also known as the Beethoven-Gerät ("Beethoven Device") and Vati und Sohn ("Daddy and Son").

Grigorovich I-Z The Grigorovich I-Z was a fighter aircraft developed in the Soviet Union during the 1930s. Advances in aircraft survivability thanks to all-metal construction and self-sealing and inert gas-filled fuel tanks led to experimentation with large-caliber weapons to shoot them down. In Soviet Union, L. V. Kurchevskiy developed a series of recoilless rifles in various calibers and in 1930 was decided to adapt the 76.2 mm (3 in) weapons for aircraft use.

Lippisch P.13a The Lippisch P.13a was an experimental ramjet-powered delta wing interceptor aircraft designed in late 1944 by Dr. Alexander Lippisch for Nazi Germany. The aircraft never made it past the drawing board, but testing of wind-tunnel models in the DVL high-speed wind tunnel showed that the design had extraordinary stability into the Mach 2.6 range.
