This article summarizes the classes of discrete symmetry groups of the Euclidean plane. The symmetry groups are named here by three naming schemes: International notation, orbifold notation, and Coxeter notation. There are three kinds of symmetry groups of the plane: 2 families of rosette groups – 2D point groups; 7 frieze groups – 2D line ...
All public schools and many private schools in Bangladesh follow the curriculum of NCTB. Starting in 2010, every year free books are distributed to students between Grade-1 to Grade-10 to eliminate illiteracy. [6] These books comprise most of the curricula of the majority of Bangladeshi schools. There are two versions of the curriculum.
It has tens of thousands of citations, being one of the most influential and cited scientific papers of all time, [6] as it gave rise to the field of information theory, with Scientific American referring to the paper as the "Magna Carta of the Information Age", [7] while the electrical engineer Robert G. Gallager called the paper a "blueprint ...
Curie's principle, or Curie's symmetry principle, is a maxim about cause and effect formulated by Pierre Curie in 1894: [1] the symmetries of the causes are to be found in the effects. [2] [3] [4] The idea was based on the ideas of Franz Ernst Neumann and Bernhard Minnigerode. Thus, it is sometimes known as the Neuman–Minnigerode–Curie ...
The root system of the exceptional Lie group E 8. Lie groups have many symmetries. Symmetry occurs not only in geometry, but also in other branches of mathematics. Symmetry is a type of invariance: the property that a mathematical object remains unchanged under a set of operations or transformations. [1]
A drawing of a butterfly with bilateral symmetry, with left and right sides as mirror images of each other.. In geometry, an object has symmetry if there is an operation or transformation (such as translation, scaling, rotation or reflection) that maps the figure/object onto itself (i.e., the object has an invariance under the transform). [1]
Asymmetric warfare (or asymmetric engagement) is a type of war between belligerents whose relative military power, strategy or tactics differ significantly. This type of warfare often, but not necessarily, involves insurgents, terrorist groups, or resistance militias operating within territory mostly controlled by the superior force.
Modern armour warfare doctrine was developed and established during the run up to World War II. A fundamental key to conventional Warfare is the concentration of force at a particular point (the [der] Schwerpunkt). Concentration of force increases the chance of victory in a particular engagement.
