frustum

In geometry, a frustum (plural: frusta or frustums) is the portion of a solid (normally a cone or pyramid) that lies between two parallel planes cutting it.

The term is commonly used in computer graphics to describe the three-dimensional region which is visible on the screen, the 'viewing frustum', which is formed by a clipped pyramid; in particular, frustum culling is a method of hidden surface determination.

In the aerospace industry, frustum is the common term for the fairing between two stages of a multistage rocket (such as the Saturn V), which is shaped like a truncated cone.

Big Science

Big Science is a term used by scientists and historians of science to describe a series of changes in science which occurred in industrial nations during and after World War II, as scientific progress increasingly came to rely on large-scale projects usually funded by national governments or groups of governments. Individual or small group efforts, or Small Science, is still relevant today as theoretical results by individual authors may have a significant impact, but very often the empirical verification requires experiments using constructions, such as the Large Hadron Collider costing between $5 and $10 billion.

Steganography

Steganography is the art and science of writing hidden messages in such a way that no one, apart from the sender and intended recipient, suspects the existence of the message, a form of security through obscurity. The word steganography is of Greek origin and means "concealed writing" from the Greek words steganos (στεγανός) meaning "covered or protected", and graphei (γράφη) meaning "writing". The first recorded use of the term was in 1499 by Johannes Trithemius in his Steganographia, a treatise on cryptography and steganography disguised as a book on magic. Generally, messages will appear to be something else: images, articles, shopping lists, or some other covertext and, classically, the hidden message may be in invisible ink between the visible lines of a private letter.

darknet

A darknet refers to any closed, private group of people communicating; however, since 2002, the term has evolved to more specifically refer to file sharing networks in general, whether that network is private or readily accessible to the public. The phrase "the darknet" is used to refer collectively to all covert communication networks.

Ason

Ason is a prestigious title (under the eight kabane system), initially conferred in the Nara period of the history of Japan, on princes who had been reduced to the commonalty.

auto-antonym

An auto-antonym (sometimes spelled autantonym), or contranym (originally spelled contronym), is a word with a homograph (a word of the same spelling) that is also an antonym (a word with the opposite meaning). Variant names include antagonym, Janus word (after the Roman god), enantiodrome, and self-antonym. It is a word with multiple meanings, one of which is defined as the reverse of one of its other meanings.

For example, the word "fast" can mean "moving quickly" as in "running fast," or it can mean "not moving" as in "stuck fast." To buckle can mean "to fasten" when used transitively or "to bend then break" intransitively. "To weather" can mean "to endure" (intransitive) or "to erode" (transitive). However such terms are just how one relates to the meaning of an object enduring or having endured weather, whether it is standing up against said weather unchanged, or being influenced negative by said weather, it is still either way being weathered and the additional valuation of its resultant meaning makes it an auto-anyonym only subjectively; when in actuality the word means simply how an object relates to the influence of weather for better or worse. That is an example of our perception adding meaning to the word where it may not initially imply such a meaning generally that would make it an auto-antonym. "Weedy" can mean "overgrown" ("The garden is weedy") or stunted ("The boy looks weedy"). "To overlook" can mean "to inspect" or "to fail to notice". "Strike", in baseball terms, can mean "to hit the ball" or "to miss the ball". This phenomenon is also called "enantionymy" or "antilogy."
