Apex (headdress)

The apex was a cap worn by the flamines and Salii at Rome. The essential part of the apex, to which alone the name properly belonged, was a pointed piece of olive-wood, the base of which was surrounded with a lock of wool. This was worn on the top of the head, and was held there either by fillets only, or, as was more commonly the case, was also fastened by means of two strings or bands, which were called apicula (Festus, s.v.), or offendices (Festus, s.v.), though the latter word is also interpreted to mean a kind of button, by which the strings were fastened under the chin (cf. Serv. ad Virg. Aen. ii.683, viii.664, x.270).

The flamines were forbidden by law to go into public, or even into the open air without the apex (Gellius x.15), and hence we find the expression of alicui apicem dialem imponere used as equivalent to the appointment of a Flamen Dialis (Livy vi.41). Sulpicius was deprived of the priesthood, only because the apex fell from his head whilst he was sacrificing (Valerius Maximus i.1 §5).

Apex (mollusc)

In anatomy, an apex (adjectival form: apical) is part of the shell of a mollusk. The apex is the pointed tip (the oldest part) of the shell of a gastropod, scaphopod, or cephalopod.

Gastropods

The word "apex" is most often used to mean the tip of the spire of the shell of a gastropod. The apex is the first-formed, and therefore the oldest, part of the shell.

To be more precise, the apex would usually be where the tip of the embryonic shell or protoconch is situated, if that is still present in the adult shell (often it is lost or eroded away).

Coiled gastropod shells

The phrase apical whorls, or protoconch, means the whorls that constitute the embryonic shell at the apex of the shell, especially when this is clearly distinguishable from the later whorls of the shell, otherwise known as the teleoconch.

Limpet-like gastropod shells

Where this feature is present, the space under the apex of a patellate or patelliform (limpet-like) gastropod shell is called the apical cavity.

Animation

Animation is the process of making the illusion of motion and change by means of the rapid display of a sequence of static images that minimally differ from each other. The illusion—as in motion pictures in general—is thought to rely on the phi phenomenon. Animators are artists who specialize in the creation of animation.

Animation can be recorded with either analogue media, a flip book, motion picture film, video tape, digital media, including formats with animated GIF, Flash animation and digital video. To display animation, a digital camera, computer, or projector are used along with new technologies that are produced.

Animation creation methods include the traditional animation creation method and those involving stop motion animation of two and three-dimensional objects, paper cutouts, puppets and clay figures. Images are displayed in a rapid succession, usually 24, 25, 30, or 60 frames per second.

History

Early examples of attempts to capture the phenomenon of motion into a still drawing can be found in paleolithic cave paintings, where animals are often depicted with multiple legs in superimposed positions, clearly attempting to convey the perception of motion.

Animation (album)

Animation is the third solo album by Yes founder-member and former lead singer Jon Anderson, released in 1982.

Overview

Animation was recorded during a busy time for Anderson when he was collaborating with Vangelis and Mike Oldfield and exploring new age and electropop.

As with the previous album Song of Seven, several well-known musicians were involved in Animation, including Simon Phillips, David Sancious and Jack Bruce.

The song All God's Children was produced by producer Tony Visconti (who had worked with more mainstream British acts such as David Bowie and T. Rex) and was released on vinyl but no CD version was published until 2006, when a limited edition CD re-release of the album (with two bonus tracks) was issued by Opio Media. The rest of the album was produced by producer Neil Kernon who had worked with acts such as Daryl Hall and John Oates

"Surrender" and "All in a Matter of Time" were released as singles.

The album was promoted with a world tour where Anderson would perform songs from the album as well as several Yes classics, mostly in medley form.

Animation (disambiguation)

Animation is the interpolation of frames over a finite period of time. As a discipline, it is practiced with the intent of creating an illusion of movement.
