biplicityThe state of being twice folded; reduplication.
biplotA kind of statistical graph, a generalization of the simple two-variable scatter plot, allowing information on both samples and variables of a data matrix to be displayed graphically.
bipotentiometryA form of potentiometry using two electrodes for measurement.
bipowerAn alternative to variance; a measure of variability based on summing the product of adjacent data points rather than summing the squares of data points.
bippA mixture of one part bismuth, two parts iodoform, and one part paraffin, blended to form a paste, applied as an antiseptic to wounds previously cleaned and dried.
bippyAn unspecified part of the anatomy, usually used in the phrase "you bet your (sweet) bippy".
bipyrazineA bicyclic aromatic heterocycle composed of two pyrazine rings linked by a direct single bond
bipyrazoleAny of several isomeric bicyclic heterocycles in which two pyrazole rings are directly linked with a single bond.
bipyrazylA univalent radical derived from bipyrazine
bipyridineAny of six isomeric bicyclic heterocycles consisting of two pyridine molecules directly linked; their derivatives have many industrial applications.
bipyridiniumA divalent cation derived from bipyridine
bipyridylAny of six isomeric aromatic compounds consisting of two pyridine groups joined directly together in a manner analogous to biphenyl
bipyrimidineAny of several isomeric bicyclic heterocycles formed from two pyrimidine rings joined by a single bond, but especially 2,2′-bipyrimidine
bipyrroleA bicyclic heterocycle composed of two pyrrole rings linked by a single bond
biquadraticOf a polynomial expression, involving only the zeroth, second, and fourth powers of a variable, as x⁴ + 3x² + 2. Sometimes extended to any expression involving the biquadrate or fourth power (but no higher powers), as x⁴ − 4x³ + 3x² − x + 1.
biquaternionAny of the numbers w+xi+yj+zk! where w, x, y, and z are complex numbers and the elements of {1, i, j, k} multiply as in the quaternion group.
biquinaryEmploying, or relating to, an arithmetical system and notation in which each decimal digit is represented by a coefficient of five and a coefficient of one
biquintileAn aspect of two planets that are distant from each other by two fifths of a great circle (72 degrees)
biquotientThe base space of a principal bundle with a homogeneous space as total space.
