Any species of raptorial birds of the family Strigidæ. They have large eyes and ears, and a conspicuous circle of feathers around each eye. They are mostly nocturnal in their habits.

A group of chiefly nighttime hunters; eighteen species occur in North America. Owls are unique among raptors in having soft plumage for virtually soundless flight. Other owl specialties include huge, forward facing eyes that can see in almost total darkness, and large ear openings that give the birds phenomenal hearing.

from Latin "ululo," for "crying out loud," symbolic bird of Athens, Greece

nocturnal bird of prey with hawk-like beak and claws and large head with front-facing eyes

The Web Ontology Language standard from W3C. Currently (2003/04) on the Recommensation track. An RDF vocabulary.

Ontology Web Language. An ontology definition language for W3C Semantic Web standards (see below).

A language based on description logic for defining structured, web-based ontologies. OWL is intended to be used when the information contained in documents needs to be processed by applications, as opposed to situations where the content only needs to be presented to humans. OWL can be used to explicitly describe the meaning of terms in vocabularies and the relationships between those terms. From the set of given OWL statements, i.e. the descriptions, an OWL Reasoner can derive further statements not explicitly stated in an ontology. See http://www.w3.org/TR/owl-features/.

(Ontology Web Language) – The ontology language, built on RDF and RDFS and inspired by DAML+OIL, that is being developed by the W3C Web Ontology working group, and is currently in "Last Call" status. See W3C, DAML, OIL, Ontology, and http://www.w3c.org/2001/sw/WebOnt

The Official Tournament and Club Word List, the official word source in competitive Scrabble in North America. The OWL contains every acceptable two- through nine-letter word, plus extensions, in list form without definitions. It replaced The Official Scrabble Players Dictionary, or OSPD, as the official Scrabble source in 1998.

As of March 1998 OWL (the Official Tournament and Club Word List published by Merriam-Webster, Inc.) is the official word source for all sanctioned NSA Clubs and Tournaments.

Since March 1998 the Official Tournament and Club Word List (OWL) published by Merriam-Webster, Inc.) was the official word source for all sanctioned NSA Clubs and Tournaments. As of March 1, 2006 the 2nd Edition is the official word source.

Okay, you know what an owl is. Because the owl was sacred to Athena, Greek goddess of wisdom, it has become the unofficial mascot of Mensa, and when you get active in Mensa you'll see lots of them. Over the years other unofficial mascots have included pelicans, unicorns, Opus the penguin, and doubtless other things--but the owl is pretty solidly entrenched.

An optical device which measures the average particle size of an essentially monodispersed aerosol by the angular degree of light polarization.

Though small in size don't be fooled by the owl. Owl holds the wisdom of the ages. These little Owl clusters may have every other totem crystal that exists. If only you had a microscope to check them all. (Clusters that are very tiny. In the size the average size points would have 5 or 6 points, where the Owl crystal could have 50. These clusters usually contain all or many of the other totem crystals. The primary way to find them is by size and feel. If you put one cluster in one hand and another cluster in the other the Owl cluster will stand out as far more powerful.)
