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.
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.
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" 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..

A photon is an elementary particle, the quantum of light and all other forms of electromagnetic radiation. It is the force carrier for the electromagnetic force, even when static via virtual photons. The effects of this force are easily observable at the microscopic and at the macroscopic level, because the photon has zero rest mass; this allows long distance interactions. Like all elementary particles, photons are currently best explained by quantum mechanics and exhibit wave–particle duality, exhibiting properties of waves and of particles. For example, a single photon may be refracted by a lens or exhibit wave interference with itself, but also act as a particle giving a definite result when its position is measured. Waves and quanta, being two observable aspects of a single phenomenon, cannot have their true nature described in terms of any mechanical model. A representation of this dual property of light, which assumes certain points on the wave front to be the seat of the energy, is also impossible. Thus, the quanta in a light wave cannot be spatially localized. Some defined physical parameters of a photon are listed.
Photon is the third studio album from Japanese electronica/rock duo Boom Boom Satellites, released on July 24, 2002.
Photon - Commin' 2 a Phase is an alternate version of the "Photon" album, released in the UK by Different Records. It features an adjusted tracklist, re-recorded versions of a number of tracks and different artwork. It was released on September 29, 2003.
Photon: The Idiot Adventures is a six-episode anime OVA series created by Masaki Kajishima. The main character, Photon, possesses superhuman strength but is extremely simple-minded. He engages in heroic adventures of different varieties. He accidentally gets married to a rebel space pilot named Keyne, and becomes involved in fighting an evil wannabe galactic emperor and his "bumbling henchmen".
The ending song, "Pinch!", is performed by Yui Horie. A manga based on the anime was written by Hiroshi Kanno.
