Simpson's paradox - Wikipedia
Simpson's paradox for quantitative data: a positive trend ( , ) appears for two separate groups, whereas a negative trend ( ) appears when the groups are combined. Visualization of Simpson's paradox on data resembling real-world variability indicates that risk of misjudgment of true causal relationship can be hard to spot. Simpson's paradox is a phenomenon in probability and statistics in which a

Palaeodictyoptera - Wikipedia
The Palaeodictyoptera are an extinct order of medium-sized to very large, primitive Palaeozoic paleopterous insects. They are informative about the evolution of wings in insects. Overview[edit] Restoration of Mazothairos They were characterized by beak-like mouthparts, used to pierce plant tissues for feeding. There is a similarity between their fore- and hindwings, and an additional pair of wingl
Structure from motion - Wikipedia
Structure from motion (SfM)[1] is a photogrammetric range imaging technique for estimating three-dimensional structures from two-dimensional image sequences that may be coupled with local motion signals. It is studied in the fields of computer vision and visual perception. Principle[edit] Digital surface model of motorway interchange construction site Real photo x SfM with texture color x SfM with
Phylogenetic comparative methods - Wikipedia
Phylogenetic comparative methods (PCMs) use information on the historical relationships of lineages (phylogenies) to test evolutionary hypotheses. The comparative method has a long history in evolutionary biology; indeed, Charles Darwin used differences and similarities between species as a major source of evidence in The Origin of Species. However, the fact that closely related lineages share man
Axial tilt - Wikipedia
The positive pole of a planet is defined by the right-hand rule: if the fingers of the right hand are curled in the direction of the rotation then the thumb points to the positive pole. The axial tilt is defined as the angle between the direction of the positive pole and the normal to the orbital plane. The angles for Earth, Uranus, and Venus are approximately 23°, 97°, and 177° respectively.In as
Peter Higgs - Wikipedia
Peter Ware Higgs CH FRS FRSE HonFInstP (born 29 May 1929) is a British theoretical physicist, Emeritus Professor at the University of Edinburgh,[6][7] and Nobel Prize laureate for his work on the mass of subatomic particles.[8][9] In the 1960s, Higgs proposed that broken symmetry in electroweak theory could explain the origin of mass of elementary particles in general and of the W and Z bosons in
Bundle adjustment - Wikipedia
A sparse matrix obtained when solving a modestly sized bundle adjustment problem. This is the arrowhead sparsity pattern of a 992×992 normal-equation (i.e. approximate Hessian) matrix. Black regions correspond to nonzero blocks. In photogrammetry and computer stereo vision, bundle adjustment is simultaneous refining of the 3D coordinates describing the scene geometry, the parameters of the relativ
