The Physics (Greek: Φυσικὴ ἀκρόασις Phusike akroasis; Latin: Physica, or Physicae Auscultationes, meaning "lectures on nature") of Aristotle is one of the foundational books of Western science and philosophy. As Martin Heidegger once wrote;
Bertrand Russell, however, says of Physics and On the Heavens that they were:
It is a collection of treatises or lessons that deal with the most general (philosophical) principles of natural or moving things, both living and non-living, rather than physical theories (in the modern sense) or investigations of the particular contents of the universe. The chief purpose of the work is to discover the principles and causes of (and not merely to describe) change, or movement, or motion (κίνησις kinesis), especially that of natural wholes (mostly living things, but also inanimate wholes like the cosmos). In the conventional Andronicean ordering of Aristotle's works, it stands at the head of, as well as being foundational to, the long series of physical, cosmological and biological treatises, whose ancient Greek title, τὰ φυσικά, means "the [writings] on nature" or "natural philosophy".
The Physics is an American hip hop group based in Seattle, Washington. It was created in the late-1990s when its members, Thig Natural (Gathigi Gishuru), Monk Wordsmith (Njuguna Gishuru) and Just D'Amato (Justin Hare) were students at O'Dea High School in Seattle. Since 2007, the trio has released three full-length albums, two EPs and several non-album singles.
The Physics are an integral part of the Seattle hip hop community, and much of their music is centered on life in Seattle ("Seward Park" and "Coronas on Madrona," for example). They are known for rapping about everyman themes such as romance, working 9-5 jobs, and enjoying life.
The Physics consists of two MCs, real-life brothers Thig Natural (often referred to as Thig Nat), and Monk Wordsmith (who functions as the group's hype man as well) and producer, Justo. All three members grew up in a neighborhood known as Seattle's South End. Thig and Monk are first-generation Americans of Kenyan descent, and Just D'Amato (also known as Justo) is half-Filipino. The Physics reference their heritage in their music, especially in the Tomorrow People track, "Journey of the Drum." Thig is also a photographer who shoots primarily fashion and street photography.
