  2. Minichess - Wikipedia

    en.wikipedia.org/wiki/Minichess

    To make the variant more playable, Silverman finally proposed to insert a row between pawns and use the board 4×5. In this variant, pawns can move two squares on their first move, if the target square is free. The 1995 game Tic Tac Chec, invented by Don Green, is played on a 4×4 board which starts empty. Each player has a knight, a rook, a ...

  3. Row and column spaces - Wikipedia

    en.wikipedia.org/wiki/Row_and_column_spaces

    The columns of A span the column space, but they may not form a basis if the column vectors are not linearly independent. Fortunately, elementary row operations do not affect the dependence relations between the column vectors. This makes it possible to use row reduction to find a basis for the column space. For example, consider the matrix

  4. Magic square - Wikipedia

    en.wikipedia.org/wiki/Magic_square

    The smallest (and unique up to rotation and reflection) non-trivial case of a magic square, order 3. In mathematics, especially historical and recreational mathematics, a square array of numbers, usually positive integers, is called a magic square if the sums of the numbers in each row, each column, and both main diagonals are the same.

  5. Span (engineering) - Wikipedia

    en.wikipedia.org/wiki/Span_(engineering)

    In engineering, span is the distance between two adjacent structural supports (e.g., two piers) of a structural member (e.g., a beam). Span is measured in the horizontal direction either between the faces of the supports (clear span) or between the centers of the bearing surfaces (effective span): [1] A span can be closed by a solid beam or by ...

  6. Oswald efficiency number - Wikipedia

    en.wikipedia.org/wiki/Oswald_efficiency_number

    It is frequently assumed that Oswald efficiency number is the same as the span efficiency factor which appears in lifting-line theory, and in fact the same symbol e is typically used for both. But this assumes that the profile drag coefficient is independent of C L {\displaystyle C_{L}} , which is certainly not true in general.

    Linear span, a set of all linear combinations of vectors; Mean, mean of a set of values (e.g.〈x〉= ... Interval, uses square brackets and parentheses; Matrix, ...

  8. Deflection (engineering) - Wikipedia

    en.wikipedia.org/wiki/Deflection_(engineering)

    The deflection at any point, , along the span of a center loaded simply supported beam can be calculated using: [1] = for The special case of elastic deflection at the midpoint C of a beam, loaded at its center, supported by two simple supports is then given by: [ 1 ] δ C = F L 3 48 E I {\displaystyle \delta _{C}={\frac {FL^{3}}{48EI}}} where

    TI's long-running TI-30 series being one of the most widely used scientific calculators in classrooms. Casio, Canon, and Sharp, produced their graphing calculators, with Casio's FX series (beginning with the Casio FX-1 in 1972 [9]). Casio was the first company to produce a Graphing calculator (Casio fx-7000G).
