Time Enough For Love
''Time Enough for Love'' is a science fiction novel by American writer Robert A. Heinlein, first published in 1973. The work was nominated for the Nebula Award for Best Novel in 1973 and both the Hugo and Locus Awards in 1974. Plot The book covers several periods from the life of Lazarus Long (born Woodrow Wilson Smith), an early beneficiary of a breeding experiment designed to increase mankind's natural lifespan. The experiment is known as the Howard Families, after the program's initiator. Lazarus is the result of more a mutation than the breeding experiment, and he is the oldest living human at more than two thousand years old. The first half of the book takes the form of several novellas connected by Lazarus's retrospective narrative. In the framing story, Lazarus has decided that life is no longer worth living, but, in what is described as a reverse '' Arabian Nights'' scenario, agrees not to end his life for as long as his companion and descendant, chief executive of th ...

Robert A
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto. Robert is also a common name in many Germanic languages, including English, German, Dutch, Norwegian, Swedish, Scots, Danish, and Icelandic. It can be use ...

Seaman (rank)
Seaman is a military rank used in many Navy, navies around the world. It is considered a junior enlisted rank and, depending on the navy, it may be a single rank on its own or a name shared by several similarly junior ranks. In the Commonwealth of Nations, Commonwealth, it is the lowest rank in the navy, while in the United States, it refers to the three lowest ranks of the United States Navy, U.S. Navy and United States Coast Guard, U.S. Coast Guard. The equivalent of the seaman is the ''matelot'' in French-speaking countries, and ''Matrose'' in German-speaking countries. Australia The Royal Australian Navy features one seaman rank, which is split into two distinct classes. Seaman and seaman* (pronounced "seaman star"), to differentiate between those who have completed their employment training and those who are in training. There is no insignia on a seaman rank slide. Canada There are 4 grades of sailor (previously the term "seaman", until it was replaced with "sailor" in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ace Books
Ace Books is a publisher of science fiction (SF) and fantasy books founded in New York City in 1952 by Aaron A. Wyn. It began as a genre publisher of mysteries and westerns, and soon branched out into other genres, publishing its first science fiction title in 1953. This was successful, and science fiction titles outnumbered both mysteries and westerns within a few years. Other genres also made an appearance, including nonfiction, gothic novels, media tie-in novelizations, and romances. Ace became known for the ''tête-bêche'' binding format used for many of its early books, although it did not originate the format. Most of the early titles were published in this "Ace Double" format, and Ace continued to issue books in varied genres, bound ''tête-bêche'', until 1973. Ace, along with Ballantine Books, was one of the leading science fiction publishers for its first ten years of operation. The death of owner A. A. Wyn in 1967 set the stage for a later decline in the publishe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blurb
A blurb is a short promotional piece accompanying a piece of creative work. It may be written by the author or publisher or quote praise from others. Blurbs were originally printed on the back or rear dust jacket of a book, and are now also found on web portals and news websites. A blurb may introduce a newspaper or a book. History In the US, the history of the blurb is said to begin with Walt Whitman's collection, ''Leaves of Grass''. In response to the publication of the first edition in 1855, Ralph Waldo Emerson had sent Whitman a congratulatory letter, including the phrase "I greet you at the beginning of a great career": the following year, Whitman had these words stamped in gold leaf on the spine of the second edition. The word ''blurb'' was coined in 1907 by American humorist Gelett Burgess (1866–1951). His short 1906 book ''Are You a Bromide?'' was presented in a limited edition to an annual trade association dinner. The custom at such events was to have a dust jack ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Incest
Incest ( ) is human sexual activity between family members or close relatives. This typically includes sexual activity between people in consanguinity (blood relations), and sometimes those related by affinity (marriage or stepfamily), adoption, or lineage. It is strictly forbidden and considered immoral in most societies, and can lead to an increased risk of genetic disorders in children. The incest taboo is one of the most widespread of all cultural taboos, both in present and in past societies. Most modern societies have laws regarding incest or social restrictions on closely consanguineous marriages. In societies where it is illegal, consensual adult incest is seen by some as a victimless crime. Some cultures extend the incest taboo to relatives with no consanguinity such as milk-siblings, step-siblings, and adoptive siblings, albeit sometimes with less intensity. Third-degree relatives (such as half-aunt, half-nephew, first cousin) on average have 12.5% common genetic heri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chastity Belt
A chastity belt is a locking item of clothing designed to prevent sexual intercourse or masturbation. Such belts were historically designed for women, ostensibly for the purpose of chastity, to protect women from rape or to dissuade women and their potential sexual partners from sexual temptation. Modern versions of the chastity belt are predominantly, but not exclusively, used in the BDSM community, and chastity belts are now designed for male wearers in addition to female wearers. According to modern myths, the chastity belt was used as an anti-temptation device during the Crusades. When the knight left for the Holy Lands on the Crusades, his Lady would wear a chastity belt to preserve her faithfulness to him. However, there is no credible evidence that chastity belts existed before the 15th century (over a century after the last Middle Eastern Crusade), and their main period of apparent use falls within the Renaissance rather than the Middle Ages.

Zygote
A zygote (, ) is a eukaryotic cell formed by a fertilization event between two gametes. The zygote's genome is a combination of the DNA in each gamete, and contains all of the genetic information of a new individual organism. In multicellular organisms, the zygote is the earliest developmental stage. In humans and most other anisogamous organisms, a zygote is formed when an egg cell and sperm cell come together to create a new unique organism. In single-celled organisms, the zygote can divide asexually by mitosis to produce identical offspring. German zoologists Oscar and Richard Hertwig made some of the first discoveries on animal zygote formation in the late 19th century. Humans In human fertilization, a released ovum (a haploid secondary oocyte with replicate chromosome copies) and a haploid sperm cell (male gamete) combine to form a single diploid cell called the zygote. Once the single sperm fuses with the oocyte, the latter completes the division of the second ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gamete
A gamete (; , ultimately ) is a haploid cell that fuses with another haploid cell during fertilization in organisms that reproduce sexually. Gametes are an organism's reproductive cells, also referred to as sex cells. In species that produce two morphologically distinct types of gametes, and in which each individual produces only one type, a female is any individual that produces the larger type of gamete—called an ovum— and a male produces the smaller type—called a sperm. Sperm cells or spermatozoa are small and motile due to the flagellum, a tail-shaped structure that allows the cell to propel and move. In contrast, each egg cell or ovum is relatively large and non-motile. In short a gamete is an egg cell (female gamete) or a sperm (male gamete). In animals, ova mature in the ovaries of females and sperm develop in the testes of males. During fertilization, a spermatozoon and ovum unite to form a new diploid organism. Gametes carry half the genetic information of an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haploid
Ploidy () is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes. Sets of chromosomes refer to the number of maternal and paternal chromosome copies, respectively, in each homologous chromosome pair, which chromosomes naturally exist as. Somatic cells, tissues, and individual organisms can be described according to the number of sets of chromosomes present (the "ploidy level"): monoploid (1 set), diploid (2 sets), triploid (3 sets), tetraploid (4 sets), pentaploid (5 sets), hexaploid (6 sets), heptaploid or septaploid (7 sets), etc. The generic term polyploid is often used to describe cells with three or more chromosome sets. Virtually all sexually reproducing organisms are made up of somatic cells that are diploid or greater, but ploidy level may vary widely between different organisms, between different tissues within the same organism, and at different stages in an organism's life cycle.

Manumission
Manumission, or enfranchisement, is the act of freeing enslaved people by their enslavers. Different approaches to manumission were developed, each specific to the time and place of a particular society. Historian Verene Shepherd states that the most widely used term is gratuitous manumission, "the conferment of freedom on the enslaved by enslavers before the end of the slave system". The motivations for manumission were complex and varied. Firstly, it may present itself as a sentimental and benevolent gesture. One typical scenario was the freeing in the master's will of a devoted servant after long years of service. A trusted bailiff might be manumitted as a gesture of gratitude. For those working as agricultural laborers or in workshops, there was little likelihood of being so noticed. In general, it was more common for older slaves to be given freedom. Legislation under the early Roman Empire put limits on the number of slaves that could be freed in wills (''lex Fufia Can ...
