Word: singularity Part of Speech: noun Etymology: From Middle English singularite, from Old French singularité, from Late Latin singulāritās (“singleness”), from Latin singulāris (“single”). By surface analysis, singular + -ity. Pronunciation: /ˌsɪŋɡjəˈlæɹətɪ/ 1. The state of being singular, distinct, peculiar, uncommon or unusual. Labels: countable, uncountable Example: Pliny addeth this ſingularity to the Indian ſoil, that it is without weeds, that the second year the very falling down of the seeds yieldeth corn. Example: I took notice of this little figure for the singularity of the instrument. 2. An unusual action or behaviour. Labels: countable, uncountable Example: When about 16 years of age I happened to meet with a book, written by one Tryon, recommending a vegetable diet. I determined to go into it. […] My refusing to eat flesh occasioned an inconveniency, and I was frequently chid for my singularity. Example: "Do you know," said she to Guido one morning, when, after asking her to sing, the Englishman had left the room in the very middle of her song, "that I have taken a fancy into my head, which quite accounts for Mr. Arden's singularities: it is, that I am like some one whom he loved and lost in early youth; and though the loss is dreadful, the love is yet pleasant to remember." 3.

The value or range of values of a function for which a derivative does not exist. Labels: countable, uncountable 6. Ellipsis of gravitational singularity (“a point or region in spacetime in which gravitational forces cause matter to have an infinite density; associated with black holes”). Labels: abbreviation, alt-of, countable, ellipsis, uncountable Example: At this singularity the laws of science and our ability to predict the future would break down. However, any observer who remained outside the black hole would not be affected by this failure of predictability, because neither light nor any other signal could reach him from the singularity. Example: Consequently the interior of a black hole is empty, with a singularity at the centre. 7. Ellipsis of technological singularity (“a hypothetical turning point in the future, the culmination of ever-accelerating technological progress, when human history as we have known it ends, and a strange new era begins. For some writers, the catalyst is superhuman machine intelligence”). Labels: abbreviation, alt-of, capitalized, countable, ellipsis, sometimes, uncountable Example: One conversation centered on the ever accelerating progress of technology and changes in the mode of human life, which gives the appearance of approaching some essential singularity in the history of the race beyond which human affairs, as we know them, could not continue. Example: Within thirty years, we will have the technological means to create superhuman intelligence. Shortly after, the human era will be ended. […] I think it's fair to call this event a singularity ("the Singularity" for the purposes of this paper). 8. Anything singular, rare, or curious. Labels: countable, obsolete, uncountable Example: Your Gallerie / Haue vve paſs'd through, not vvithout much content / In many ſingularities; […] Example: [N]either my Birth, my Education, nor the generall courſe of my life can promiſe no ſingularitie in any part of thoſe Actes they treate of: […] 9.

Labels: countable, uncountable Example: Marriage is the mother of the world, and preserves Kingdomes, and fils Cities, and Churches, and Heaven itself: Celibate, like the flie in the heart of an apple, dwels in a perpetuall sweetnesse, but sits alone, and is confin'd, and dies in singularity; but marriage, like the useful bee, builds a house and gathers sweetnesse from every flower, and labours and unites into Societies and Republicks, and sends out colonies, and feeds the world with delicacies, and obeys its king, and keeps order, and exercises many vertues, and promotes the interest of mankind, and is that state of good things to which God hath designed the present constitution of the world. Example: Gradually the implication of biblical monotheism created an entailment of singularity and monogamy in sexual relations.
