  2. Irreducible fraction - Wikipedia

    en.wikipedia.org/wiki/Irreducible_fraction

    In the first step both numbers were divided by 10, which is a factor common to both 120 and 90. In the second step, they were divided by 3. The final result, ⁠ 4 / 3 ⁠ , is an irreducible fraction because 4 and 3 have no common factors other than 1.

  3. Tetrahedral number - Wikipedia

    en.wikipedia.org/wiki/Tetrahedral_number

    Tetrahedral numbers can be modelled by stacking spheres. For example, the fifth tetrahedral number (Te 5 = 35) can be modelled with 35 billiard balls and the standard triangular billiards ball frame that holds 15 balls in place. Then 10 more balls are stacked on top of those, then another 6, then another three and one ball at the top completes ...

    Purves was optimistic about his invention's prospects. As reported in a 1932 Popular Science magazine article, after a filmed test drive in 1932 on a beach in Weston-super-Mare, Somerset, he stated that the Dynasphere "reduced locomotion to the simplest possible form, with consequent economy of power", [1] and that it was "the high-speed vehicle of the future".

  5. Ratio - Wikipedia

    en.wikipedia.org/wiki/Ratio

    As for fractions, the simplest form is considered that in which the numbers in the ratio are the smallest possible integers. Thus, the ratio 40:60 is equivalent in meaning to the ratio 2:3, the latter being obtained from the former by dividing both quantities by 20. Mathematically, we write 40:60 = 2:3, or equivalently 40:60∷2:3.

  6. Disdyakis triacontahedron - Wikipedia

    In the above coordinates, the first 12 vertices form a regular icosahedron, the next 20 vertices (those with R) form a regular dodecahedron, and the last 30 vertices (those with S) form an icosidodecahedron. Normalizing all vertices to the unit sphere gives a spherical disdyakis triacontahedron, shown in the adjacent figure.

  9. Slide rule - Wikipedia

    en.wikipedia.org/wiki/Slide_rule

    A more modern form of slide rule was created in 1859 by French artillery lieutenant Amédée Mannheim, who was fortunate both in having his rule made by a firm of national reputation, and its adoption by the French Artillery. Mannheim's rule had two major modifications that made it easier to use than previous general-purpose slide rules.
