Lehi (Book of Mormon prophet)

According to the Book of Mormon, Lehi (/ˈliːhaɪ/LEE-hy) was a prophet who lived in Jerusalem during the reign of king Zedekiah (approximately 600 BC). Lehi was an Israelite of the Tribe of Manasseh, and father to Nephi, another prominent prophet in the Book of Mormon. In the first book of the Book of Mormon, First Nephi, Lehi and Nephi lead their family out of Jerusalem, and across the sea to the "promised land" (the Americas). Mormon scholar Hugh Nibley has suggested that he was a merchant and contemporary of the Seven Wise Men of Greece. The prophet is the namesake of the modern-day city of Lehi, Utah.

Life according to the Book of Mormon

According to the Book of Mormon narrative, the families of Lehi, his friend Ishmael and another man named Zoram left Jerusalem some time before its destruction by the Babylonians in approximately 587 BC. Lehi's group proceeded southward down the Arabian Peninsula until they reached a location called Nahom. For some time, Lehi dwelt in a tent. 1 Nephi 2:15 Ishmael is reported to have died by this time, and he was buried at this location.

Book of Mormon

The Book of Mormon is a sacred text of the Latter Day Saint movement, which adherents believe contains writings of ancient prophets who lived on the American continent from approximately 2200 BC to AD 421. It was first published in March 1830 by Joseph Smith as The Book of Mormon: An Account Written by the Hand of Mormon upon Plates Taken from the Plates of Nephi.

According to Smith's account and the book's narrative, the Book of Mormon was originally written in otherwise unknown characters referred to as "reformed Egyptian" engraved on golden plates. Smith said that the last prophet to contribute to the book, a man named Moroni, buried it in a hill in present-day New York, then returned to earth in 1827 as an angel, revealing the location of the book to Smith, and instructing him to translate it into English for use in the restoration of Christ's true church in the latter days. Critics claim that it was fabricated by Smith, drawing on material and ideas from contemporary 19th-century works rather than translating an ancient record.

Book

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.

Keturi brūkšniai is a polemical book by Lithuanian historian Edvardas Gudavičius, written in the Lithuanian language. It was published in 2002 by Aidai in Vilnius (ISBN 9955-445-55-6). It does not have any proper title, but publishers and book sellers usually put four dashes (Lithuanian: Keturi brūkšniai) as the title.

Book (graph theory)

In graph theory, a book graph (often written  ) may be any of several kinds of graph.

One kind, which may be called a quadrilateral book, consists of p quadrilaterals sharing a common edge (known as the "spine" or "base" of the book). A book of this type is the Cartesian product of a star and K₂ .

A second type, which might be called a triangular book, is the complete tripartite graph K_1,1,p. It is a graph consisting of triangles sharing a common edge. A book of this type is a split graph. This graph has also been called a .

Given a graph , one may write for the largest book (of the kind being considered) contained within .

The term "book-graph" has been employed for other uses. Barioli used it to mean a graph composed of a number of arbitrary subgraphs having two vertices in common. (Barioli did not write for his book-graph.)
