Problem: Anthropology:

Media anthropology (also known as anthropology of media or mass media) emphasizes ethnographic studies as a means of understanding producers, audiences, and other cultural and social aspects of mass media. The types of ethnographic contexts explored range from contexts of media production (e.g., ethnographies of newsrooms in newspapers, journalists in the field, film production) to contexts of media reception, following audiences in their everyday responses to media. Other types include cyber anthropology, a relatively new area of internet research, as well as ethnographies of other areas of research which happen to involve media, such as development work, social movements, or health education. This is in addition to many classic ethnographic contexts, where media such as radio, the press, new media and television have started to make their presences felt since the early 1990s.

Problem: Molotov%E2%80%93Ribbentrop Pact:

At the beginning of the 1930s, the Nazi Party's rise to power increased tensions between Germany and the Soviet Union along with other countries with ethnic Slavs, who were considered "Untermenschen" (inferior) according to Nazi racial ideology. Moreover, the anti-Semitic Nazis associated ethnic Jews with both communism and financial capitalism, both of which they opposed. Consequently, Nazi theory held that Slavs in the Soviet Union were being ruled by "Jewish Bolshevik" masters. In 1934, Hitler himself had spoken of an inescapable battle against both Pan-Slavism and Neo-Slavism, the victory in which would lead to "permanent mastery of the world", though he stated that they would "walk part of the road with the Russians, if that will help us." The resulting manifestation of German anti-Bolshevism and an increase in Soviet foreign debts caused GermanSoviet trade to dramatically decline.[b] Imports of Soviet goods to Germany fell to 223 million Reichsmarks in 1934 as the more isolationist Stalinist regime asserted power and the abandonment of postWorld War I Treaty of Versailles military controls decreased Germany's reliance on Soviet imports.[clarification needed]

Problem: Treaty:

The end of a treaty, the eschatocol (or closing protocol), is often signaled by a clause like "in witness whereof" or "in faith whereof," the parties have affixed their signatures, followed by the words "DONE at," then the site(s) of the treaty's execution and the date(s) of its execution. The date is typically written in its most formal, longest possible form. For example, the Charter of the United Nations was "DONE at the city of San Francisco the twenty-sixth day of June, one thousand nine hundred and forty-five." If the treaty is executed in multiple copies in different languages, that fact is always noted, and is followed by a stipulation that the versions in different languages are equally authentic.

What is the nature of the different versions of a treaty executed in multiple languages?
---
A: equally authentic

Problem: Planck constant:

The black-body problem was revisited in 1905, when Rayleigh and Jeans (on the one hand) and Einstein (on the other hand) independently proved that classical electromagnetism could never account for the observed spectrum. These proofs are commonly known as the "ultraviolet catastrophe", a name coined by Paul Ehrenfest in 1911. They contributed greatly (along with Einstein's work on the photoelectric effect) to convincing physicists that Planck's postulate of quantized energy levels was more than a mere mathematical formalism. The very first Solvay Conference in 1911 was devoted to "the theory of radiation and quanta". Max Planck received the 1918 Nobel Prize in Physics "in recognition of the services he rendered to the advancement of Physics by his discovery of energy quanta".

When was the last Solvay Conference held?
