    Then, for example, (0, ⁠ 3 / 2 ⁠) and (1, ⁠ 1 / 2 ⁠) are a spin representations of dimensions 2⋅ ⁠ 3 / 2 ⁠ + 1 = 4 and (2 + 1)(2⋅ ⁠ 1 / 2 ⁠ + 1) = 6 respectively. According to the above paragraph, there are subspaces with spin both ⁠ 3 / 2 ⁠ and ⁠ 1 / 2 ⁠ in the last two cases, so these representations cannot likely ...

    [a] The parsec unit is obtained by the use of parallax and trigonometry, and is defined as the distance at which 1 AU subtends an angle of one arcsecond [1] (⁠ 1 / 3600 ⁠ of a degree). The nearest star, Proxima Centauri , is about 1.3 parsecs (4.2 light-years) from the Sun : from that distance, the gap between the Earth and the Sun spans ...

    The history of scientific method considers changes in the methodology of scientific inquiry, not the history of science itself. The development of rules for scientific reasoning has not been straightforward; scientific method has been the subject of intense and recurring debate throughout the history of science, and eminent natural philosophers and scientists have argued for the primacy of ...

    As in China, there is a lack of continuity in Indian mathematics; significant advances are separated by long periods of inactivity. [127] Pāṇini (c. 5th century BC) formulated the rules for Sanskrit grammar. [131] His notation was similar to modern mathematical notation, and used metarules, transformations, and recursion. [132]
