Each instance <code>COL</code> of <a href="http://sw.opencyc.org/concept/Mx4rqEYnNVMqEdaSKAACs0x8nw" class="cyc_term">AtemporalNecessarilyEssentialCollectionType</a> (ANECT) is a collection satisfying three conditions: (1) <code>COL</code> is disjoint with (see <a href="http://sw.opencyc.org/concept/Mx4rvViA45wpEbGdrcN5Y29ycA" class="cyc_term">disjointWith</a>) <a href="http://sw.opencyc.org/concept/Mx4rvViAxJwpEbGdrcN5Y29ycA" class="cyc_term">TemporalThing</a>, (2) every instance <code>INST</code> of <code>COL</code> is an instance of <code>COL</code> essentially (i.e. <code>INST</code> is an instance of <code>COL</code>, and could not exist without being an instance of <code>COL</code>), and (3) condition (2) is a necessary truth about <code>COL</code>. Positive examples of ANECTs include <a href="http://sw.opencyc.org/concept/Mx4rvViAzJwpEbGdrcN5Y29ycA" class="cyc_term">Collection</a>, <a href="http://sw.opencyc.org/concept/Mx4rvVieEpwpEbGdrcN5Y29ycA" class="cyc_term">Integer</a>, and <a href="http://sw.opencyc.org/concept/Mx4rvViAzZwpEbGdrcN5Y29ycA" class="cyc_term">Relation</a> (each of which is a collection of atemporals and is such that, necessarily, all of its instances are in it essentially). Negative examples include <a href="http://sw.opencyc.org/concept/Mx4rvVjpUZwpEbGdrcN5Y29ycA" class="cyc_term">SpatialThing</a> (though arguably it is necessary that all of its instances are essentially instances of it, it is not disjoint with <a href="http://sw.opencyc.org/concept/Mx4rvViAxJwpEbGdrcN5Y29ycA" class="cyc_term">TemporalThing</a>) and <a href="http://sw.opencyc.org/concept/Mx4rwP4FM5wpEbGdrcN5Y29ycA" class="cyc_term">UniqueAnatomicalPartType</a> (which, though disjoint with <a href="http://sw.opencyc.org/concept/Mx4rvViAxJwpEbGdrcN5Y29ycA" class="cyc_term">TemporalThing</a>, has instances, such as <a href="http://sw.opencyc.org/concept/Mx4rvVjvDpwpEbGdrcN5Y29ycA" class="cyc_term">Heart</a>, that could exist even if they weren't instances of it; e.g. it might have been the case that every creature with a heart had at least two hearts). There are no known examples of Cyc-reified collections satisfying conditions (1) and (2) but not (3), but one can be contrived. Suppose that all of today's winning lottery numbers were primes. Now consider the collection: (<a href="http://sw.opencyc.org/concept/Mx4rvrhK-JwpEbGdrcN5Y29ycA" class="cyc_term">CollectionUnionFn</a> (<a href="http://sw.opencyc.org/concept/Mx4rvVjkdpwpEbGdrcN5Y29ycA" class="cyc_term">TheSet</a> <a href="http://sw.opencyc.org/concept/Mx4rvVjrdZwpEbGdrcN5Y29ycA" class="cyc_term">PrimeNumber</a> TodaysWinningLotteryNumbers)) This collection is clearly disjoint with <a href="http://sw.opencyc.org/concept/Mx4rvViAxJwpEbGdrcN5Y29ycA" class="cyc_term">TemporalThing</a> and, by hypothesis, all of its instances are in it essentially (as each prime number is essentially a prime number). But this last fact is not necessarily true of this collection: the collection might have had instances that belonged to it only contingently (i.e. not essentially), as it might have been the case that one of today's winning lottery numbers was non-prime, and no number is such that it is essentially one of today's winning lottery numbers. When asserting that something is an instance or specialization of a given instance of ANECT, it is appropriate to do so in the <a href="http://sw.opencyc.org/concept/Mx4r3_SgQU2iEdaCwAACs0x8nw" class="cyc_term">UniversalVocabularyMt</a> (q.v.). Indeed, ANECT was specially defined to facilitate the movement of appropriate assertions to that microtheory. Cf. <a href="http://sw.opencyc.org/concept/Mx4rGeylLJTfEdqAAAACs0uFOQ" class="cyc_term">PragmaticallyDecontextualizedCollection</a>. ElectricalQuantity electrical quantity A type of <a href="http://sw.opencyc.org/concept/Mx4rhywBFkT6EdaAAACgye4oEQ" class="cyc_term">PhysicalQuantity</a>. The concept <a href="http://sw.opencyc.org/concept/Mx4rTjJYTGVbQdeQg__1FBraog" class="cyc_term">ElectricalQuantity</a> is a <a href="http://sw.opencyc.org/concept/Mx4rvVkDZJwpEbGdrcN5Y29ycA" class="cyc_term">QuantityType</a> and a <a href="http://sw.opencyc.org/concept/Mx4rC-8cJgBpEdqAAAACs0uFOQ" class="cyc_term">UnitOfMeasureConcept</a>. non aspectual quantity A specialization of <a href="http://sw.opencyc.org/concept/Mx4rLxknOmVZQdeQUJLqO_1Uzg" class="cyc_term">ScalarQuantity</a> (q.v.). This is the collection of all "non-aspectual" quantities: those that can always be attributed to an object simpliciter, without specifying a particular aspect or dimension of the object that the quantity has to do with. For example, the degrees of <a href="http://sw.opencyc.org/concept/Mx4rvVj_hJwpEbGdrcN5Y29ycA" class="cyc_term">Flammability</a> are non-aspectual; an object could be attributed its flammability-level with a generic binary "hasQuantity" predicate. Conversely, a particular <a href="http://sw.opencyc.org/concept/Mx4rvViAmpwpEbGdrcN5Y29ycA" class="cyc_term">Distance</a> is aspect-relative; attributing a distance to any multi-dimensional object is relative to the dimension along which the distance is being measured (compare e.g. <a href="http://sw.opencyc.org/concept/Mx4rvVjbZpwpEbGdrcN5Y29ycA" class="cyc_term">lengthOfObject</a> and <a href="http://sw.opencyc.org/concept/Mx4rvVjgA5wpEbGdrcN5Y29ycA" class="cyc_term">widthOfObject</a>). NonAspectualQuantity Pretty String (<a href="http://sw.opencyc.org/concept/Mx4rwLSVCpwpEbGdrcN5Y29ycA" class="cyc_term">prettyString</a> TERM STRING) means that STRING is the English word or expression (sequence of words) commonly used to refer to TERM. The predicate <a href="http://sw.opencyc.org/concept/Mx4rwLSVCpwpEbGdrcN5Y29ycA" class="cyc_term">prettyString</a> is used by the code which generates CycL to English paraphrases, but its applicability is not restricted to this use. prettyString UnitOfMeasureConcept A <a href="http://sw.opencyc.org/concept/Mx4ret7qgOKgEdmAAAACs6hfSg" class="cyc_term">ConceptTypeByDomain</a> (q.v.). Instances of <a href="http://sw.opencyc.org/concept/Mx4rC-8cJgBpEdqAAAACs0uFOQ" class="cyc_term">UnitOfMeasureConcept</a> are collections and relations having to do with unit of measurement functions and the kinds of quantities they return as values. Important specializations and instances of <a href="http://sw.opencyc.org/concept/Mx4rvViAqpwpEbGdrcN5Y29ycA" class="cyc_term">UnitOfMeasure</a>, major specializations or <a href="http://sw.opencyc.org/concept/Mx4rvViAp5wpEbGdrcN5Y29ycA" class="cyc_term">ScalarInterval</a>, and relations that are important to measurement theory are instances of this collection. unit of measure concept scalar intervals quantity topic ScalarIntervals-Quantity-Topic A specialization of <a href="http://sw.opencyc.org/concept/Mx4rr-2NGp7sQdidoL5VyxYMGg" class="cyc_term">MeasurableQuantity</a> (q.v.). Each instance of <a href="http://sw.opencyc.org/concept/Mx4rUstvYKCIQdiBWaekaRIs-w" class="cyc_term">OneDimensionalQuantity</a> is a measurable quantity that is not defined in terms of (i.e. as the product or ratio of) other quantities. For example, (<a href="http://sw.opencyc.org/concept/Mx4rvVi3VJwpEbGdrcN5Y29ycA" class="cyc_term">Mile</a> 65) and (<a href="http://sw.opencyc.org/concept/Mx4rvVjrNJwpEbGdrcN5Y29ycA" class="cyc_term">HoursDuration</a> 1) are both instances of <a href="http://sw.opencyc.org/concept/Mx4rUstvYKCIQdiBWaekaRIs-w" class="cyc_term">OneDimensionalQuantity</a>; but (<a href="http://sw.opencyc.org/concept/Mx4rvVkDkZwpEbGdrcN5Y29ycA" class="cyc_term">MilesPerHour</a> 65), derived by dividing the former quantity by the latter, is not (cf. <a href="http://sw.opencyc.org/concept/Mx4rU9w69qCIQdiaX7o2wbs-og" class="cyc_term">MultiDimensionalQuantity</a>). Specializations of <a href="http://sw.opencyc.org/concept/Mx4rUstvYKCIQdiBWaekaRIs-w" class="cyc_term">OneDimensionalQuantity</a> include <a href="http://sw.opencyc.org/concept/Mx4rvViAmpwpEbGdrcN5Y29ycA" class="cyc_term">Distance</a>, <a href="http://sw.opencyc.org/concept/Mx4rvVjb5pwpEbGdrcN5Y29ycA" class="cyc_term">Mass</a>, and <a href="http://sw.opencyc.org/concept/Mx4rvViApZwpEbGdrcN5Y29ycA" class="cyc_term">Time_Quantity</a>. Each one-dimensional quantity is equal to the result of applying some <a href="http://sw.opencyc.org/concept/Mx4ruFr2Fp-7QdiS0NRO_LP5CA" class="cyc_term">OneDimensionalUnitOfMeasure</a> (q.v.) to some number or other <a href="http://sw.opencyc.org/concept/Mx4rnVZQSiCmEdaAAACgyZzFrg" class="cyc_term">NumericInterval</a> (or pair of such intervals). If a <a href="http://sw.opencyc.org/concept/Mx4rUstvYKCIQdiBWaekaRIs-w" class="cyc_term">OneDimensionalQuantity</a> is multiplied or divided by a numeric-interval, the result is still a one-dimensional quantity; if two one-dimensional quantities that are <a href="http://sw.opencyc.org/concept/Mx4r31ZqOrDgQdiBDYcJa-SoRg" class="cyc_term">numericallyComparable</a> (q.v.) are added or subtracted, the result is still a one-dimensional quantity. Conversely, whenever one <a href="http://sw.opencyc.org/concept/Mx4rUstvYKCIQdiBWaekaRIs-w" class="cyc_term">OneDimensionalQuantity</a> is multiplied or divided by another <a href="http://sw.opencyc.org/concept/Mx4rUstvYKCIQdiBWaekaRIs-w" class="cyc_term">OneDimensionalQuantity</a>, the result is a <a href="http://sw.opencyc.org/concept/Mx4rVQ8MvqCIQdicLoOa1pZefg" class="cyc_term">TwoDimensionalQuantity</a>. Two quantities that are not numerically-comparable cannot be added to or substracted from each other. And when a <a href="http://sw.opencyc.org/concept/Mx4rUstvYKCIQdiBWaekaRIs-w" class="cyc_term">OneDimensionalQuantity</a> is multiplied or divided by (or divides) a <a href="http://sw.opencyc.org/concept/Mx4rVQ8MvqCIQdicLoOa1pZefg" class="cyc_term">TwoDimensionalQuantity</a>, the result is in many cases a <a href="http://sw.opencyc.org/concept/Mx4r-7GRzKCIQdiHEaxh2Wf1-g" class="cyc_term">ThreeDimensionalQuantity</a> (q.v.).
