Tool

A tool is any physical item that can be used to achieve a goal, especially if the item is not consumed in the process. Tool use by humans dates back millions of years, and other animals are also known to employ simple tools.

Tools that are used in particular fields or activities may have different designations such as "instrument", "utensil", "implement", "machine", "device," or "apparatus". The set of tools needed to achieve a goal is "equipment". The knowledge of constructing, obtaining and using tools is technology.

History

Anthropologists believe that the use of tools was an important step in the evolution of mankind. Because tools are used extensively by both humans and wild chimpanzees, it is widely assumed that the first routine use of tools took place prior to the divergence between the two species. These early tools, however, were likely made of perishable materials such as sticks, or consisted of unmodified stones that cannot be distinguished from other stones as tools.

Stone artifacts only date back to about 2.5 million years ago. However, a 2010 study suggests the hominin species Australopithecus afarensis ate meat by carving animal carcasses with stone implements. This finding pushes back the earliest known use of stone tools among hominins to about 3.4 million years ago.

Programming tool

A programming tool or software development tool is a computer program that software developers use to create, debug, maintain, or otherwise support other programs and applications. The term usually refers to relatively simple programs, that can be combined together to accomplish a task, much as one might use multiple hand tools to fix a physical object. The ability to use a variety of tools productively is one hallmark of a skilled software engineer.

The most basic tools are a source code editor and a compiler or interpreter, which are used ubiquitously and continuously. Other tools are used more or less depending on the language, development methodology, and individual engineer, and are often used for a discrete task, like a debugger or profiler. Tools may be discrete programs, executed separately – often from the command line – or may be parts of a single large program, called an integrated development environment (IDE). In many cases, particularly for simpler use, simple ad hoc techniques are used instead of a tool, such as print debugging instead of using a debugger, manual timing (of overall program or section of code) instead of a profiler, or tracking bugs in a text file or spreadsheet instead of a bug tracking system.

Tool (song)

"Tool" is a 7" single by Baboon that was released in 1993 on Silver Girl Records. Side A is 33rpm while side B is 45rpm.

The song "Tool" also appears on the band's first album, Face Down in Turpentine, though the album version is a different recording. The recording of "Tool" from this single also appears on the Get It Through Your Thick Skull compilation.

This version of the first b-side ("Why'd You Say Die?") is also on Face Down in Turpentine and Baboon's 1996 The Numb E.P..

Personnel

Ænima

Ænima (/ˈɒnɪmə/) is the second full-length studio album by American rock band Tool. It was released in vinyl format on September 17, 1996 and in compact disc format on October 1, 1996 through Zoo Entertainment. The album was recorded and cut at Ocean Way, Hollywood and The Hook, North Hollywood from 1995 to 1996. The album was produced by David Bottrill.

The album debuted at No. 2 on the Billboard 200 chart upon its initial release, and was certified triple platinum by the RIAA on March 4, 2003. The album appeared on several lists of the best albums of 1996, including that of Kerrang! and Terrorizer. The title track won the Grammy Award for Best Metal Performance in 1998. In 2003, Ænima was ranked the sixth most influential album of all time by Kerrang!

Background

Ænima was Tool's first release with former Peach bassist Justin Chancellor.

The title Ænima is a combination of the words 'anima' (Latin for 'soul' associated with the ideas of "life force" and a term often used by psychologist Carl Jung) and 'enema', the medical procedure.

Ion

An ion (/ˈaɪən, -ɒn/) is an atom or a molecule in which the total number of electrons is not equal to the total number of protons, giving the atom or molecule a net positive or negative electrical charge. Ions can be created, by either chemical or physical means, via ionization.

In chemical terms, if a neutral atom loses one or more electrons, it has a net positive charge and is known as a cation.

If an atom gains electrons, it has a net negative charge and is known as an anion.

An ion consisting of a single atom is an atomic or monatomic ion; if it consists of two or more atoms, it is a molecular or polyatomic ion. Because of their electric charges, cations and anions attract each other and readily form ionic compounds, such as salts.

In the case of physical ionization of a medium, such as a gas, what are known as "ion pairs" are created by ion impact, and each pair consists of a free electron and a positive ion.

History of discovery

The word ion is the Greek ἰόν, ion, "going", the present participle of ἰέναι, ienai, "to go". This term was introduced by English physicist and chemist Michael Faraday in 1834 for the then-unknown species that goes from one electrode to the other through an aqueous medium. Faraday did not know the nature of these species, but he knew that since metals dissolved into and entered a solution at one electrode, and new metal came forth from a solution at the other electrode, that some kind of substance moved through the solution in a current, conveying matter from one place to the other.

Institute of Noetic Sciences

The Institute of Noetic Sciences (IONS) is an American non-profit parapsychological research institute. It was co-founded in 1973 by former astronaut Edgar Mitchell, along with investor Paul N. Temple, and others interested in purported paranormal phenomena, in order to encourage and conduct research on noetic theory and human potentials.

The institute conducts research on such topics such as spontaneous remission,meditation,consciousness, alternative healing practices, consciousness-based healthcare, spirituality, human potential, psychic abilities, psychokenesis and survival of consciousness after bodily death. The institute maintains a free database, available on the Internet, with citations to more than 6,500 articles about whether physical and mental health benefits might be connected to meditation and yoga.

Headquartered outside Petaluma, California, the organization is situated on a 200-acre (81 ha) campus that includes offices, a research laboratory and a retreat center (originally the campus of World College West). Its current director is Cassandra Vieten. Other researchers associated with it include Dean Radin and Rupert Sheldrake.
