Darkness, the polar opposite to brightness, is understood to be an absence of visible light. It is also the appearance of black in a colored space.
Humans are unable to distinguish color when either light or darkness predominate. In conditions of insufficient light, perception is achromatic and ultimately, black.
The emotional response to darkness has generated metaphorical usages of the term in many cultures.
The perception of darkness differs from the mere absence of light due to the effects of after images on perception. In perceiving, the eye is active, and that part of the retina that is unstimulated produces a complementary afterimage.
In terms of physics, an object is said to be dark when it absorbs photons, causing it to appear dim compared to other objects. For example, a matte black paint does not reflect much visible light and appears dark, whereas white paint reflects much light and appears bright. For more information see color.
Light cannot be absorbed without limit. According to the principle of the conservation of Energy, energy cannot be created or destroyed; it can only be converted from one type to another. Consequently, most objects that absorb visible light reemit it as heat. So, although an object may appear dark, it is likely bright at a frequency that humans cannot perceive. For more information see thermodynamics.
Tyler is an English (old English) word which means door keeper of an inn. It is also thought to be a derived occupational name derived from "tiler", one who makes tiles. It is used both as a surname, and as given name for both genders. Among the earliest recorded use of the surname is from the 14th century; Wat Tyler of Kent, South East England.
Anubis (/əˈnuːbᵻs/ or /əˈnjuːbᵻs/;Ancient Greek: Ἄνουβις) is the Greek name of a god associated with mummification and the afterlife in ancient Egyptian religion, usually depicted as a canine or a man with a canine head. Archeologists identified the sacred animal of Anubis as an Egyptian canid, that at the time was called the golden jackal, but recent genetic testing has caused the Egyptian animals to be reclassified as the African golden wolf.
Like many ancient Egyptian deities, Anubis assumed different roles in various contexts. Depicted as a protector of graves as early as the First Dynasty (c. 3100 – c. 2890 BC), Anubis was also an embalmer. By the Middle Kingdom (c. 2055 – 1650 BC), Anubis was replaced by Osiris in his role as Lord of the underworld. One of his prominent roles was as a god who ushered souls into the afterlife. He attended the weighing scale during the "Weighing of the Heart," in which it was determined whether a soul would be allowed to enter the realm of the dead. Despite being one of the most ancient and "one of the most frequently depicted and mentioned gods" in the Egyptian pantheon, Anubis played almost no role in Egyptian myths.
A book is a set of written, printed, illustrated, or blank sheets, made of ink, paper, parchment, or other materials, fastened together to hinge at one side. A single sheet within a book is a leaf, and each side of a leaf is a page. A set of text-filled or illustrated pages produced in electronic format is known as an electronic book, or e-book.
Books may also refer to works of literature, or a main division of such a work. In library and information science, a book is called a monograph, to distinguish it from serial periodicals such as magazines, journals or newspapers. The body of all written works including books is literature. In novels and sometimes other types of books (for example, biographies), a book may be divided into several large sections, also called books (Book 1, Book 2, Book 3, and so on). An avid reader of books is a bibliophile or colloquially, bookworm.
A shop where books are bought and sold is a bookshop or bookstore. Books can also be borrowed from libraries. Google has estimated that as of 2010, approximately 130,000,000 unique titles had been published. In some wealthier nations, printed books are giving way to the usage of electronic or e-books, though sales of e-books declined in the first half of 2015.
Neil deGrasse Tyson (/ˈniːəl dəˈɡræs ˈtaɪsən/; born October 5, 1958) is an American astrophysicist, cosmologist, author, and science communicator. Since 1996, he has been the Frederick P. Rose Director of the Hayden Planetarium at the Rose Center for Earth and Space in New York City. The center is part of the American Museum of Natural History, where Tyson founded the Department of Astrophysics in 1997 and has been a research associate in the department since 2003.
Born in New York City, Tyson became interested in astronomy at the age of nine after a visit to the Hayden Planetarium. After graduating from the Bronx High School of Science, where he was editor-in-chief of the Physical Science Journal, he completed a bachelor's degree in physics at Harvard University in 1980. After receiving a master's degree in astronomy at the University of Texas at Austin in 1983, he earned his master's (1989) and doctorate (1991) in astrophysics at Columbia University. For the next three years, he was a postdoctoral research associate at Princeton University, and in 1994, he joined the Hayden Planetarium as a staff scientist and the Princeton faculty as a visiting research scientist and lecturer. In 1996, he became director of the planetarium and oversaw its $210-million reconstruction project, which was completed in 2000.
