| Minute of arc A minute of arc or arcminute (MOA) is a unit of angular measurement, equal to one sixtieth (1/60) of one degree. Since one degree is defined as one three hundred sixtieth (1/360) of a circle, 1 minute of arc is 1/21,600 of the amount of arc in a closed circle. It is used in those fields which require a unit for the expression of small angles, such as astronomy or marksmanship.There are 148,510,800 square arcminutes in a complete sphere. Minute_of_arc

| Transgenic maize Transgenic maize (corn) has been deliberately genetically modified to have agronomically desirable traits. Traits that have been engineered into corn are resistance to herbicides and incorporation of a gene that codes for the Bacillus thuringiensis (Bt) toxin, protecting plants from insect pests. Hybrids with both herbicide and pest resistance have also been produced. Transgenic maize is currently grown commercially in the United States. Transgenic_maize

| Category theory mathematics, category theory deals in an abstract way with mathematical structures and relationships between themsets and functions to objects linked in diagrams by morphisms or arrows. One of the simplest examples of a category (which is a very important concept in topology) is that of groupoid, defined as a category whose arrows or morphisms are all invertible.Categories now appear in most branches of mathematics and also in some areas of theoretical computer science where they correspond to types and mathematical physics where they can be used to describe vector spaces.
