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.

Audioslave (album)

Audioslave is the eponymous debut studio album by the American rock supergroup Audioslave and was released on November 19, 2002 (see 2002 in music). It features the hit singles "Cochise", "Show Me How to Live", "What You Are", "Like a Stone", and "I Am the Highway". The record was certified triple platinum in the US. "Like a Stone" was nominated for the 2004 Grammy Award for Best Hard Rock Performance.

Background

Audioslave was formed after Zack de la Rocha left Rage Against the Machine and the remaining members were searching for another vocalist. Producer and friend Rick Rubin suggested that they contact Chris Cornell. Rubin played the remaining Rage Against the Machine band members the Soundgarden song "Slaves & Bulldozers" to showcase his ability. Cornell was in the writing process of a second solo album, but decided to shelve that and pursue the opportunity to work with Tom Morello, Tim Commerford and Brad Wilk when they approached him. Morello described Cornell: "He stepped to the microphone and sang the song and I couldn't believe it. It didn't just sound good. It sounded transcendent. And... when there is an irreplaceable chemistry from the first moment, you can't deny it." The quartet wrote 21 songs during 19 days of rehearsal and began working in the studio in late May 2001.

Hypnotize (System of a Down song)

"Hypnotize" is the lead single for Armenian American rock band System of a Down's album of the same name, which was released on November 22, 2005 (see 2005 in music). The video was filmed on September 28, 2005, at the Van Andel Arena in Grand Rapids, Michigan. It reached number one on Billboard's Hot Modern Rock Tracks chart and is the band's biggest international hit.

As in many Mezmerize/Hypnotize songs, guitarist Daron Malakian accompanies Serj Tankian in the vocal sections. Serj and Daron perform a harmony in the refrain before and after the instrumental bridge. The combination of the two vocalists gives the song a vocal range, with Serj handling the lower verses and Daron handling the higher verses. Musically, "Hypnotize" changes modes in several places. The opening guitar riff and early verses are an upbeat melody that switches between the I (melodic) and V (Hindu) modes of F# melodic minor. The later riffs and the outro to the song are in the more commonly heard VI (natural) mode of F# minor. This mixing of modes creates the song's characteristic psychedelic feeling.
