Here is a question about this article: First recognized in 1900 by Max Planck, it was originally the proportionality constant between the minimal increment of energy, E, of a hypothetical electrically charged oscillator in a cavity that contained black body radiation, and the frequency, f, of its associated electromagnetic wave. In 1905 the value E, the minimal energy increment of a hypothetical oscillator, was theoretically associated by Einstein with a "quantum" or minimal element of the energy of the electromagnetic wave itself. The light quantum behaved in some respects as an electrically neutral particle, as opposed to an electromagnetic wave. It was eventually called the photon.
What is the answer to this question: What did the light quantum, in some ways, behave as?
****
So... an electrically neutral particle


Here is a question about this article: The Soviet Union, which feared Western powers and the possibility of "capitalist encirclements", had little faith either that war could be avoided, or faith in the Polish army, and wanted nothing less than an ironclad military alliance with France and Britain that would provide a guaranteed support for a two-pronged attack on Germany; thus, Stalin's adherence to the collective security line was purely conditional. Britain and France believed that war could still be avoided, and that the Soviet Union, weakened by the Great Purge, could not be a main military participant, a point that many military sources were at variance with, especially Soviet victories over the Japanese Kwantung army on the Manchurian frontier. France was more anxious to find an agreement with the USSR than was Britain; as a continental power, it was more willing to make concessions, more fearful of the dangers of an agreement between the USSR and Germany. These contrasting attitudes partly explain why the USSR has often been charged with playing a double game in 1939: carrying on open negotiations for an alliance with Britain and France while secretly considering propositions from Germany.
What is the answer to this question: Why did western power believe that the soviet government wouldn’t partake in another world war?

So... Great Purge


Here is a question about this article: Two aspects of indigenous pre-Hispanic culture that withstood time are chenchule' and inafa'maolek. Chenchule' is the intricate system of reciprocity at the heart of Chamorro society. It is rooted in the core value of inafa'maolek. Historian Lawrence Cunningham in 1992 wrote, "In a Chamorro sense, the land and its produce belong to everyone. Inafa'maolek, or interdependence, is the key, or central value, in Chamorro culture ... Inafa'maolek depends on a spirit of cooperation and sharing. This is the armature, or core, that everything in Chamorro culture revolves around. It is a powerful concern for mutuality rather than individualism and private property rights."
What is the answer to this question: What two indiginous pre-hispanic culture has survived to this point?
****
So...
chenchule' and inafa'maolek
