  2. Dividing line between metals and nonmetals - Wikipedia

    en.wikipedia.org/wiki/Dividing_line_between...

    This line has been called the amphoteric line, [2] the metal-nonmetal line, [3] the metalloid line, [4] [5] the semimetal line, [6] or the staircase. [2] [n 1] While it has also been called the Zintl border [8] or the Zintl line [9] [10] these terms instead refer to a vertical line sometimes drawn between groups 13 and 14.

  3. Standard form - Wikipedia

    en.wikipedia.org/wiki/Standard_form

    Standard form may refer to a way of writing very large or very small numbers by comparing the powers of ten. It is also known as Scientific notation. Numbers in standard form are written in this format: a×10 n Where a is a number 1 ≤ a < 10 and n is an integer. ln mathematics and science. Standard Form (SF) is the name of a set of forms used ...

  4. Bromocresol purple - Wikipedia

    en.wikipedia.org/wiki/Bromocresol_purple

    Similar to bromocresol green, the structure of bromocresol purple changes with pH.Changing the level of acidity causes a shift in the equilibrium between two different structures that have different colors.

  5. Geometric median - Wikipedia

    en.wikipedia.org/wiki/Geometric_median

    For the 1-dimensional case, the geometric median coincides with the median.This is because the univariate median also minimizes the sum of distances from the points. (More precisely, if the points are p 1, ..., p n, in that order, the geometric median is the middle point (+) / if n is odd, but is not uniquely determined if n is even, when it can be any point in the line segment between the two ...

  6. Gravitational acceleration - Wikipedia

    en.wikipedia.org/wiki/Gravitational_acceleration

    Gravitational acceleration. In physics, gravitational acceleration is the acceleration of an object in free fall within a vacuum (and thus without experiencing drag). This is the steady gain in speed caused exclusively by gravitational attraction. All bodies accelerate in vacuum at the same rate, regardless of the masses or compositions of the ...

  7. Hermite normal form - Wikipedia

    en.wikipedia.org/wiki/Hermite_normal_form

    In linear algebra, the Hermite normal form is an analogue of reduced echelon form for matrices over the integers Z.Just as reduced echelon form can be used to solve problems about the solution to the linear system Ax=b where x is in R n, the Hermite normal form can solve problems about the solution to the linear system Ax=b where this time x is restricted to have integer coordinates only.

    The plan received support from conservatives such as Dick Armey, [62] but attracted criticism from other conservatives such as Richard Viguerie and paleoconservatives such as Phyllis Schlafly and Pat Buchanan, who, as described by The New York Times, collectively viewed Pence as lending "his conservative prestige to a form of liberal amnesty".
