Adamant and similar words are used to refer to any especially hard substance, whether composed of diamond, some other gemstone, or some type of metal. Both adamant and diamond derive from the Greek word αδαμαστος (adamastos), meaning "untameable". Adamantite and adamantium (a metallic name derived from the Neo-Latin ending -ium) are also common variants.

Adamantine has, throughout ancient history, referred to anything that was made of a very hard material. Virgil describes Tartarus as having a screeching gate protected by columns of solid adamantine (Aeneid book VI). Later, by the Middle Ages, the term came to refer to diamond, as it was the hardest material then known, and remains the hardest non-synthetic material known.

It was in the Middle Ages, too, that adamantine hardness and the lodestone's magnetic properties became confused and combined, leading to an alternate definition in which "adamant" means magnet, falsely derived from the Latin adamare, which means to love or be attached to. Another connection was the belief that adamant (the diamond definition) could block the effects of a magnet. This was addressed in chapter III of Pseudodoxia Epidemica, for instance.

Vivek (or Bivek/Bibek in West Bengal and Nepal) (विवेक in Devanagari script) is a masculine Hindu or Buddhist given name that is popular in South Asia, particularly India and Nepal.

In Sanskrit as in modern Hindi, Nepali and Bengali, Vivek / Bibek / Bivek literally means conscience.

A remix is an alternative version of a recorded song, made from an original version. Sometimes this term is also used for alterations of media or recreation other than song (film, literature, beverages etc.).

A remixer uses audio mixing to compose an alternate master recording of a song, adding or subtracting elements, or simply changing the equalization, dynamics, pitch, tempo, playing time, or almost any other aspect of the various musical components. Some remixes involve substantial changes to the arrangement of a recorded work, but many are harmonic, such as creating a "vocal up" version of a song that emphasizes the lead singer's voice. Contemporary remixes are often produced in a Digital Audio Workstation (DAW), which allow producers to reorganize tracks and apply various effects.

Songs are remixed for a variety of reasons:

Remixes should not be confused with edits, which usually involve shortening a final stereo master for marketing or broadcasting purposes. Another distinction should be made between a remix and a cover. A remix song recombines audio pieces from a recording to create an altered version of the song. A cover is a recording of a song that was previously recorded by someone else.
