Levée en masse (French pronunciation: [ləve ɑ̃ mɑs] or, in English, mass levy [1]) is a French term used for a policy of mass national conscription, often in the face of invasion. The concept originated during the French Revolutionary Wars, particularly for the period following 16 August 1793, [2] when able-bodied men aged 18 to 25 were ...
It is generally used to describe a targeted killing of civilians en masse by an armed group or person. The word is a loan of a French term for "butchery" or "carnage". [2] [3] Other terms with overlapping scope include war crime, pogrom, mass killing, mass murder, and extrajudicial killing.
The mass of an atom or other particle can be compared more precisely and more conveniently to that of another atom, and thus scientists developed the dalton (also known as the unified atomic mass unit). By definition, 1 Da (one dalton) is exactly one-twelfth of the mass of a carbon-12 atom, and thus, a carbon-12 atom has a mass of exactly 12 Da.
Several different inclusion criteria are used; there is no generally accepted definition. [2] [3] Gun Violence Archive, a nonprofit research group that tracks shootings and their characteristics in the United States, defines a mass shooting as an incident in which four or more people, excluding the perpetrator(s), are shot in one location at roughly the same time.

Mass killing is a concept which has been proposed by genocide scholars who wish to define incidents of non-combat killing which are perpetrated by a government or a state.A mass killing is commonly defined as the killing of group members without the intention to eliminate the whole group, [1] or otherwise the killing of large numbers of people without a clear group membership.
The slug is a derived unit of mass in a weight-based system of measures, most notably within the British Imperial measurement system and the United States customary measures system. Systems of measure either define mass and derive a force unit or define a base force and derive a mass unit [1] (cf. poundal, a
Let the percentage of the total mass divided between these two particles vary from 100% P 1 and 0% P 2 through 50% P 1 and 50% P 2 to 0% P 1 and 100% P 2, then the center of mass R moves along the line from P 1 to P 2. The percentages of mass at each point can be viewed as projective coordinates of the point R on this line, and are termed ...
Mass murder is the violent crime of killing a number of people, typically simultaneously or over a relatively short period of time and in close geographic proximity. [ 1 ] [ 2 ] A mass murder typically occurs in a single location where one or more persons kill several others.
