In philosophy, hyle ( /ˈhaɪliː/; from Ancient Greek: ὕλη) refers to matter or stuff. It can also be the material cause underlying a change in Aristotelian philosophy. The Greeks originally had no word for matter in general, as opposed to raw material suitable for some specific purpose or other, so Aristotle adapted the word for "wood" to this purpose. The idea that everything physical is made of the same basic substance holds up well under modern science, although it may be thought of more in terms of energy or matter/energy.

The matter of hyle is closely related to that of substance, in so far as both endure a change in form, or transformation. Aristotle defined primary substance as that which can neither be predicated nor attributed to something else, and he explained the transformation between the four terrestrial elements in terms of an abstract primary matter that underlies each element due to the four combinations of two properties: hot or cold and wet or dry. He stipulated that transformations between opposing elements, where both properties differ, must be analyzed as two discreet steps wherein one of the two properties changes to it's contrary while the other remains unchanged, (see essence and hylomorphism).

Hikaru Utada (宇多田 ヒカル, Utada Hikaru^?, born January 19, 1983), known by her stage name Utada (English /uːˈtɑːdə/) in America and Europe, is a Japanese-American singer, songwriter, arranger, and producer. Since the release of her Japanese debut album First Love, which went on to become the best-selling album in Oricon history, Utada has had three of her Japanese studio albums in the list of Top 10 best-selling albums ever in Japan (number 1, 4, 8) and six of her albums (including one English-language and one compilation) charting within the 275 Best-Selling Japanese albums list. Utada has had twelve number-one singles on the Oricon Singles chart, with two notable record achievements for a female solo or group artist: five million-sellers and four in the Top 100 All-Time Best-selling Singles. Utada has an estimated more than 52 million records sold worldwide.

She was described by Time Magazine as a "Diva On Campus," a reference to her having attended Columbia University for a brief, career-break semester in 2000. In 2009, she was considered "the most influential artist of the decade" in the Japanese landscape by The Japan Times.

Kevin Corbett is an applied mathematician and the owner and CEO of Axiom Consulting located in Bergen County, New Jersey. His current work and research relates to inhalation exposure with a primary interest in nanoparticle aerosol generation and measurement devices.

Corbett graduated magna cum laude from Rutgers–Newark in 2008, Magna Cum Laude and received that school's Samuel L. Greitzer mathematics award. After leaving Rutgers he moved into the field of forensic accounting with his focus specifically on cost engineering. He later worked with toxicologist Dr. Rudolph Jaeger in the field of inhalation toxicology. Although not published, he has brought numerous ideas to many researchers working in the fields of aerosol exposure/technology.

Corbett is also an alumnus of the Institute of Audio Research (NYC), where he studied and practiced acoustical engineering before entering the recording industry. His understanding of Analog/Digital Audio Acoustics, Professional Audio Technology, and MIDI (Musical Instrument Digital Interface) allowed Corbett the opportunity to work in some of the most renowned studios in the New York City area, with some of the most notable names in music. His work was primarily based in the Urban Genre which consisted of working acts such as Lance Rivera, Untertainment, "Big Un", Eddie F (Untouchables), Smooth B (Nice & Smooth), Capone-N-Noreaga (Militainment), AZ (rapper), Nokio (Dru Hill), Pastor Troy, Beyonce, Chad Elliot, Darren Lighty (Untouchables), and Bruno Beatz (Atlas Recording).
