[2] [3] In layman terms, any surface defines the same bivector if it is parallel to the same plane (same attitude), has the same area, and same orientation (see figure). Bivectors are generated by the exterior product on vectors: given two vectors a and b , their exterior product a ∧ b is a bivector, as is any sum of bivectors.

The term "Bible" can refer to the Hebrew Bible or the Christian Bible, which contains both the Old and New Testaments. [2]The English word Bible is derived from Koinē Greek: τὰ βιβλία, romanized: ta biblia, meaning "the books" (singular βιβλίον, biblion). [3]
Scofield Reference Bible, page 1115. This page includes Scofield's note on John 1:17. The Scofield Bible had several innovative features. Most important, it printed what amounted to a commentary on the biblical text alongside the Bible instead of in a separate volume, the first to do so in English since the Geneva Bible (1560). [2]
A bivector is an element of the antisymmetric tensor product of a tangent space with itself. In geometric algebra, also, a bivector is a grade 2 element (a 2-vector) resulting from the wedge product of two vectors, and so it is geometrically an oriented area, in the same way a vector is an oriented line segment.
Now (hr 2) 2 = (−1)(−1) = +1, and the biquaternion curve {exp θ(hr 2) : θ ∈ R} is a unit hyperbola in the plane {x + yr 2 : x, y ∈ R}. The spacetime transformations in the Lorentz group that lead to FitzGerald contractions and time dilation depend on a hyperbolic angle parameter. In the words of Ronald Shaw, "Bivectors are logarithms ...
The torque or curl is then a normal vector field in this 3rd dimension. By contrast, geometric algebra in 2 dimensions defines these as a pseudoscalar field (a bivector), without requiring a 3rd dimension. Similarly, the scalar triple product is ad hoc, and can instead be expressed uniformly using the exterior product and the geometric product.
A two-vector or bivector [1] is a tensor of type () and it is the dual of a two-form, meaning that it is a linear functional which maps two-forms to the real numbers (or more generally, to scalars). The tensor product of a pair of vectors is a two-vector.
