  1. Infinity

    Infinity refers to something without any limit, and is a concept relevant in a number of fields, predominantly mathematics and physics. The English word infinity derives from Latin infinitas, which can be translated as "unboundedness", itself calqued from the Greek word apeiros, meaning "endless". In mathematics, "infinity" is often treated as if it were a number but it is not the same sort of number as the real numbers. In number systems incorporating infinitesimals, the reciprocal of an infinitesimal is an infinite number, i.e., a number greater than any real number. Georg Cantor formalized many ideas related to infinity and infinite sets during the late 19th and early 20th centuries. In the theory he developed, there are infinite sets of different sizes. For example, the set of integers is countably infinite, while the infinite set of real numbers is uncountable.

The New Hacker's Dictionary

  1. infinity

    1. The largest value that can be represented in a particular type of variable (register, memory location, data type, whatever). 2. minus infinity: The smallest such value, not necessarily or even usually the simple negation of plus infinity. In N-bit twos-complement arithmetic, infinity is 2N-1 - 1 but minus infinity is - (2N-1), not -(2N-1 - 1). Note also that this is different from time T equals minus infinity, which is closer to a mathematician's usage of infinity.

Examples of Infinity in a Sentence

  1. Sandeep Aggarwal:

    AI is a paradigm shift. Hope we embrace it vs on the mercy of others. It is automation raise to the power infinity and much more...

  2. H.P. Lovecraft, "The Call of Cthulhu":

    The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents. We live on a placid island of ignorance in the midst of black seas of infinity, and it was not meant that we should voyage far. The sciences, each straining in its own direction, have hitherto harmed us little; but some day the piecing together of dissociated knowledge will open up such terrifying vistas of reality, and of our frightful position therein, that we shall either go mad from the revelation or flee from the deadly light into the peace and safety of a new dark age.

  4. Carl DeHaven:

    In Da' Beginning To most of us...Infinity is a thing ahead of us. In reality it's both ahead and behind us. Some suggest that "in the beginning there was God". Others tell us a "big Bang" occurred. Some say an understanding of a beginning is not possible. Our calendar started on A.D. and we mark time bother before and after that day. Beginnings have endings. Could be there's no beginnings or endings. One of the aspects of existence is that of "continuance". Motive determines whether what we begin with be beneficial or not. Could be best to think a bit before we......begin. KnowyerLoved, CWD
