Scale (music)
In music theory, a scale is any set of musical notes ordered by fundamental frequency or pitch. A scale ordered by increasing pitch is an ascending scale, and a scale ordered by decreasing pitch is a descending scale. Often, especially in the context of the common practice period, most or all of the melody and harmony of a musical work is built using the notes of a single scale, which can be conveniently represented on a staff with a standard key signature. Due to the principle of octave equivalence, scales are generally considered to span a single octave, with higher or lower octaves simply repeating the pattern. A musical scale represents a division of the octave space into a certain number of scale steps, a scale step being the recognizable distance (or interval) between two successive notes of the scale. However, there is no need for scale steps to be equal within any scale and, particularly as demonstrated by microtonal music, there is no limit to how many notes can ...

Massacre Of Lwów Professors
In July 1941, 25 Polish academics from the city of Lwów (now Lviv, Ukraine) along with the 25 of their family members were killed by Nazi German occupation forces. By targeting prominent citizens and intellectuals for elimination, the Nazis hoped to prevent anti-Nazi activity and to weaken the resolve of the Polish resistance movement. According to an eyewitness the executions were carried out by an ''Einsatzgruppe'' unit () under the command of Karl Eberhard Schöngarth with the participation of Ukrainian translators in German uniforms. Background Before September 1939 and the German invasion of Poland, Lwów, then in the Second Polish Republic, had 318,000 inhabitants of different ethnic groups and religions, 60% of whom were Poles, 30% Jews and about 10% Ukrainians and Germans.

Gestapo
The (), abbreviated Gestapo (; ), was the official secret police of Nazi Germany and in German-occupied Europe. The force was created by Hermann Göring in 1933 by combining the various political police agencies of Prussia into one organisation. On 20 April 1934, oversight of the Gestapo passed to the head of the ''Schutzstaffel'' (SS), Heinrich Himmler, who was also appointed Chief of German Police by Hitler in 1936. Instead of being exclusively a Prussian state agency, the Gestapo became a national one as a sub-office of the (SiPo; Security Police). From 27 September 1939, it was administered by the Reich Security Main Office (RSHA). It became known as (Dept) 4 of the RSHA and was considered a sister organisation to the (SD; Security Service). During World War II, the Gestapo played a key role in the Holocaust.

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mechanical Engineering
Mechanical engineering is the study of physical machines that may involve force and movement. It is an engineering branch that combines engineering physics and mathematics principles with materials science, to design, analyze, manufacture, and maintain mechanical systems. It is one of the oldest and broadest of the engineering branches. Mechanical engineering requires an understanding of core areas including mechanics, dynamics, thermodynamics, materials science, structural analysis, and electricity. In addition to these core principles, mechanical engineers use tools such as computer-aided design (CAD), computer-aided manufacturing (CAM), and product lifecycle management to design and analyze manufacturing plants, industrial equipment and machinery, heating and cooling systems, transport systems, aircraft, watercraft, robotics, medical devices, weapons, and others. Mechanical engineering emerged as a field during the Industrial Revolution in Europe in the 18th century; ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polish–Ukrainian War
The Polish–Ukrainian War, from November 1918 to July 1919, was a conflict between the Second Polish Republic and Ukrainian forces (both the West Ukrainian People's Republic and Ukrainian People's Republic). The conflict had its roots in ethnic, cultural and political differences between the Polish and Ukrainian populations living in the region, as Poland and both Ukrainian republics were successor states to the dissolved Russian and Austrian empires. The war started in Eastern Galicia after the dissolution of the Austro-Hungarian Empire and spilled over into Chełm Land and Volhynia (Wołyń) regions formerly belonging to the Russian Empire, which were both claimed by the Ukrainian State (a client state of the German Empire) and the Ukrainian People's Republic. Poland re-occupied the disputed territory on 18 July 1919. Background The origins of the conflict lie in the complex nationality situation in Galicia at the turn of the 20th century. As a result of the House of Ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Captain
Captain is a title, an appellative for the commanding officer of a military unit; the supreme leader of a navy ship, merchant ship, aeroplane, spacecraft, or other vessel; or the commander of a port, fire or police department, election precinct, etc. In militaries, the captain is typically at the level of an officer commanding a company or battalion of infantry, a ship, or a battery of artillery, or another distinct unit. The term also may be used as an informal or honorary title for persons in similar commanding roles. Etymology The term "captain" derives from (, , or 'the topmost'), which was used as title for a senior Byzantine military rank and office. The word was Latinized as capetanus/catepan, and its meaning seems to have merged with that of the late Latin "capitaneus" (which derives from the classical Latin word "caput", meaning head). This hybridized term gave rise to the English language term captain and its equivalents in other languages (, , , , , , , , , kapitány, K ...

Sapper
A sapper, also called a pioneer (military), pioneer or combat engineer, is a combatant or soldier who performs a variety of military engineering duties, such as breaching fortifications, demolitions, bridge-building, laying or clearing minefields, preparing field defenses, and road and airfield construction and repair. They are also trained and equipped to serve as provisional infantry, fighting as such as a secondary mission. A sapper's duties facilitate and support movement, defense, and survival of allied forces and impede those of enemies. The term "sapper" is used in the British Army and Commonwealth of Nations, Commonwealth nations and the U.S. military. The word "sapper" comes from the French word ''sapeur'', itself being derived from the verb ''saper'' (to undermine, to dig under a wall or building to cause its collapse). Historical origin Sapping A sapper, in the sense first used by the French military, was one who dug trenches to allow besieging forces to advance ...

Military Reserve Force
A military reserve force is a military organization whose members have military and civilian occupations. They are not normally kept under arms, and their main role is to be available when their military requires additional manpower. Reserve forces are generally considered part of a permanent standing body of armed forces, and allow a nation to reduce its peacetime military expenditures and maintain a force prepared for war. In countries with a volunteer military, such as Canada, Spain, the United States and the United Kingdom, reserve forces are civilians who maintain military skills by training periodically (typically one weekend per month). They may do so as individuals or as members of standing reserve regiments—for example, the UK's Army Reserve (United Kingdom), Army Reserve. A militia, home guard, State defense force, state guard or state military may constitute part of a military reserve force, such as the National Guard (United States), United States National Guard a ...
