https://en.wikipedia.org/wiki/Fluctuating%20asymmetry | Fluctuating asymmetry (FA), is a form of biological asymmetry, along with anti-symmetry and direction asymmetry. Fluctuating asymmetry refers to small, random deviations away from perfect bilateral symmetry. This deviation from perfection is thought to reflect the genetic and environmental pressures experienced through... |
https://en.wikipedia.org/wiki/Hobbesian%20trap | The Hobbesian trap (or Schelling's dilemma) is a theory that explains why preemptive strikes occur between two groups, out of bilateral fear of an imminent attack. Without outside influences this situation will lead to a fear spiral (catch-22, vicious circle, Nash equilibrium) in which fear will lead to an arms race wh... |
https://en.wikipedia.org/wiki/Centroid | In mathematics and physics, the centroid, also known as geometric center or center of figure, of a plane figure or solid figure is the point defined by the arithmetic mean position of all the points in the surface of the figure. In a polytope, it can be found using the arithmetic mean position of the vertices. The same... |
https://en.wikipedia.org/wiki/ACOT2 | Acyl-CoA thioesterase 2, also known as ACOT2, is an enzyme which in humans is encoded by the ACOT2 gene.
Acyl-CoA thioesterases, such as ACOT2, are a group of enzymes that hydrolyze Coenzyme A (CoA) esters, such as acyl-CoAs, bile CoAs, and CoA esters of prostaglandins, to the corresponding free acid and CoA. ACOT2 sh... |
https://en.wikipedia.org/wiki/Cavity%20optomechanics | Cavity optomechanics is a branch of physics which focuses on the interaction between light and mechanical objects on low-energy scales. It is a cross field of optics, quantum optics, solid-state physics and materials science. The motivation for research on cavity optomechanics comes from fundamental effects of quantum ... |
https://en.wikipedia.org/wiki/Geometry | Geometry (; ) is a branch of mathematics concerned with properties of space such as the distance, shape, size, and relative position of figures. Geometry is, along with arithmetic, one of the oldest branches of mathematics. A mathematician who works in the field of geometry is called a geometer. Until the 19th century,... |
