Self
The self is the subject of one's own experience of phenomena: perception, emotions, thoughts. In phenomenology, it is conceived as what experiences, and there isn't any experiencing without an experiencer, the self. The self is therefore an "immediate given", an intrinsic dimension of the fact of experiencing phenomena. In some other trends of philosophy, the self is instead seen as requiring a reflexive perception of oneself, the individual person, meaning the self in such a view is an object of consciousness.
The self has been studied extensively by philosophers and psychologists and is central to many world religions. With the recent rise in technology, the self has been discussed under various new emerging fields, such as Technoself Studies.
Philosophy
The philosophy of self seeks to describe essential qualities that constitute a person's uniqueness or essential being. There have been various approaches to defining these qualities. The self can be considered that being which is the source of consciousness, the agent responsible for an individual's thoughts and actions, or the substantial nature of a person which endures and unifies consciousness over time.
Self (programming language)
Self is an object-oriented programming language based on the concept of prototypes. Self was a dialect of Smalltalk, being dynamically typed and using just-in-time compilation (JIT) as well as the prototype-based approach to objects: it was first used as an experimental test system for language design in the 1980s and 1990s. In 2006, Self was still being developed as part of the Klein project, which was a Self virtual machine written fully in Self. The latest version is 4.5.0 released in January 2014.
Several just-in-time compilation techniques were pioneered and improved in Self research as they were required to allow a very high level object oriented language to perform at up to half the speed of optimized C. Much of the development of Self took place at Sun Microsystems, and the techniques they developed were later deployed for Java's HotSpot virtual machine.
At one point a version of Smalltalk was implemented in Self. Because it was able to use the JIT this also gave extremely good performance.
Stef Lang
HIDDEN ERROR: Usage of "Distribution" is not recognized
Stef Lang (born Stephanie Jane Lang, December 30, 1988) is a Canadian singer, songwriter, and producer who resides in New York City. Originally from the Vancouver Island town of Ladysmith, BC, Lang left home at 17 to move to Vancouver, BC and pursue her musical career. Lang, often booking her own shows, played every pub, bar, club and café she could, while honing her songwriting craft and interning at a recording studio where she learned how to produce. Known for engaging performances and edgy lyrics, Lang released her first full-length album, The Underdog, in May 2010, distributed by Hipjoint Music/Universal Music Canada. Her hit single, Mr. Immature achieved mainstream success when it peaked at #5 on The Billboard Chart for Canadian Emerging Artists. Lang is known for her vocal feature on Canadian radio hit "Rollin" by Toronto's rapper ISH, which was released via Warner Music Group in 2012. In 2013, her vocals were featured on "Last Chance" by EDM artist Kaskade from his Grammy nominated album Atmosphere. Lang also co-wrote and was featured on the song "All These Wounds" by EDM artist Ilan Bluestone and BT, which was released May 25, 2015 on the Anjunabeats Worldwide05 Compilation. Lang's third full-length album is set to release in 2015 as a two-part EP series.
Oxybenzone
Oxybenzone or benzophenone-3 (trade names Milestab 9, Eusolex 4360, Escalol 567, KAHSCREEN BZ-3) is an organic compound. It is a white solid that is readily soluble in most organic solvents. Oxybenzone belongs to the class of aromatic ketones known as benzophenones. It is a component of many sunscreen lotions.
Structure and electronic structure
Being a conjugated molecule, oxybenzone absorbs at lower energies than many aromatic molecules. As in related compounds, the hydroxyl group is hydrogen bonded to the ketone. This interaction contributes to oxybenzone's light-absorption properties. At low temperatures, however, it is possible to observe both the phosphorescence and the triplet-triplet absorption spectrum. At 175 K the triplet lifetime is 24 ns. The short lifetime has been attributed to a fast intramolecular hydrogen transfer between the oxygen of the C=O and the OH.
Production
Oxybenzone is produced by Friedel-Crafts reaction of benzoyl chloride with 3-methoxyphenol(3-hydroxyanisole).
Properties of water
Water (H
2O) is the most abundant compound on Earth's surface, covering 70 percent of the planet. In nature, water exists in liquid, solid, and gaseous states. It is in dynamic equilibrium between the liquid and gas states at standard temperature and pressure. At room temperature, it is a tasteless and odorless liquid, nearly colorless with a hint of blue. Many substances dissolve in water and it is commonly referred to as the universal solvent. Because of this, water in nature and in use is rarely pure and some properties may vary from those of the pure substance. However, there are also many compounds that are essentially, if not completely, insoluble in water. Water is the only common substance found naturally in all three common states of matter and it is essential for all life on Earth. Water makes up 55% to 78% of the human body.
