The axial twist theory ( a.k.a. axial twist hypothesis ) is a proposed scientific theory that has been proposed to explain a range of unusual aspects of the body plan of vertebrates (including humans ). [ 1 ] It states that the rostral part of the head is "turned around" regarding the rest of the body. [ 2 ] This end-p... | https://en.wikipedia.org/wiki/Axial_twist_theory |
In the geometry of the Euclidean plane , axiality is a measure of how much axial symmetry a shape has. It is defined as the ratio of areas of the largest axially symmetric subset of the shape to the whole shape. Equivalently it is the largest fraction of the area of the shape that can be covered by a mirror reflection ... | https://en.wikipedia.org/wiki/Axiality_(geometry) |
In physics and mathematics , axiality and rhombicity are two characteristics of a symmetric second-rank tensor in three-dimensional Euclidean space , describing its directional asymmetry.
Let A denote a second-rank tensor in R 3 , which can be represented by a 3-by-3 matrix . We assume that A is symmetric. This implie... | https://en.wikipedia.org/wiki/Axiality_and_rhombicity |
The axillary lines are the anterior axillary line, midaxillary line and the posterior axillary line.
The anterior axillary line [ 1 ] is a coronal line on the anterior torso marked by the anterior axillary fold . It's the imaginary line that runs down from the point midway between the middle of the clavicle and the la... | https://en.wikipedia.org/wiki/Axillary_lines |
In molecular physics , the Axilrod–Teller potential (also known as the Axilrod–Teller–Muto or ATM potential ) describes the interaction potential (energy) between three atoms , capturing effects beyond simple pairwise attractions. It builds on the London dispersion forces , using perturbation theory to correct for the ... | https://en.wikipedia.org/wiki/Axilrod–Teller_potential |
