The Gods Themselves
''The Gods Themselves'' is a 1972 science fiction novel written by Isaac Asimov, and his first original work in the science fiction genre in fifteen years (not counting his 1966 novelization of '' Fantastic Voyage''). It won the Nebula Award for Best Novel in 1972, and the Hugo Award for Best Novel in 1973. The book is divided into three main parts, which were first published in ''Galaxy Magazine'' and ''Worlds of If'' as three consecutive stories. Overview The book is divided into three sections; the first set on the Earth, the second set on a planet in a parallel universe, and the third set on a lunar colony. In the first section, the book opens at chapter six to give context to the other chapters, and alternates timelines. Thus, the flow is Chapter six overview of Chapter one, then Chapter one. Next, is Chapter six overview of Chapter two, then Chapter two. Following chapter three to five, chapter six then concludes, and the story proceeds with chapter seven. The main plot- ...

Isotope
Isotopes are two or more types of atoms that have the same atomic number (number of protons in their nuclei) and position in the periodic table (and hence belong to the same chemical element), and that differ in nucleon numbers (mass numbers) due to different numbers of neutrons in their nuclei. While all isotopes of a given element have almost the same chemical properties, they have different atomic masses and physical properties. The term isotope is formed from the Greek roots isos ( ἴσος "equal") and topos ( τόπος "place"), meaning "the same place"; thus, the meaning behind the name is that different isotopes of a single element occupy the same position on the periodic table. It was coined by Scottish doctor and writer Margaret Todd in 1913 in a suggestion to the British chemist Frederick Soddy. The number of protons within the atom's nucleus is called its atomic number and is equal to the number of electrons in the neutral (non-ionized) atom. Each atomic numbe ...

Intuition (knowledge)
Intuition is the ability to acquire knowledge without recourse to conscious reasoning. Different fields use the word "intuition" in very different ways, including but not limited to: direct access to unconscious knowledge; unconscious cognition; gut feelings; inner sensing; inner insight to unconscious pattern-recognition; and the ability to understand something instinctively, without any need for conscious reasoning.Intuition and consciousness – Rosenblatt AD, Thickstun JT. Psychoanal Q. 1994 Oct;63(4):696-714. Intuitive knowledge tends to be approximate. The word ''intuition'' comes from the Latin verb ''intueri'' translated as "consider" or from the late middle English word ''intuit'', "to contemplate". Use of intuition is sometimes referred to as responding to a "gut feeling" or "trusting your gut".Wilding, M.How to Stop Overthinking and Start Trusting your Gut ''Harvard Business Review'', published 10 March 2022, accessed 21 September 2022 Psychology Freud According to Si ...

Selene
In ancient Greek mythology and religion, Selene (; grc-gre, Σελήνη , meaning "Moon"''A Greek–English Lexicon's.v. σελήνη) is the goddess and the personification of the Moon. Also known as Mene, she is traditionally the daughter of the Titans Hyperion and Theia, and sister of the sun god Helios and the dawn goddess Eos. She drives her moon chariot across the heavens. Several lovers are attributed to her in various myths, including Zeus, Pan, and the mortal Endymion. In post-classical times, Selene was often identified with Artemis, much as her brother, Helios, was identified with Apollo. Selene and Artemis were also associated with Hecate and all three were regarded as moon and lunar goddesses, but only Selene was regarded as the personification of the Moon itself. Her Roman equivalent is Luna. Names and etymology The name "Selene" is derived from the Greek noun ''selas'' ('), meaning "light, brightness, gleam". In the Doric and Aeolic dialects, her nam ...

Moon
The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of Australia). The Moon is a planetary-mass object with a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term and larger than all known dwarf planets of the Solar System. It lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth of Earth's at , with Jupiter's moon Io being the only satellite in the Solar System known to have a higher surface gravity and density. The Moon orbits Earth at an average distance of , or about 30 times Earth's diameter. Its gravitational influence is the main driver of Earth's tides and very slowly lengthens Earth's day. The Moon's orbit around Earth has a sidereal period of 27.3 days. During each synodic period ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metamorphosis
Metamorphosis is a biological process by which an animal physically develops including birth or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation. Some insects, fish, amphibians, mollusks, crustaceans, cnidarians, echinoderms, and tunicates undergo metamorphosis, which is often accompanied by a change of nutrition source or behavior. Animals can be divided into species that undergo complete metamorphosis (" holometaboly"), incomplete metamorphosis ("hemimetaboly"), or no metamorphosis (" ametaboly"). Scientific usage of the term is technically precise, and it is not applied to general aspects of cell growth, including rapid growth spurts. Generally organisms with a larva stage undergo metamorphosis, and during metamorphosis the organism loses larval characteristics. References to "metamorphosis" in mammals are imprecise and only colloquial, but historically idealist ideas of transformation ...

Masturbation
Masturbation is the sexual stimulation of one's own genitals for sexual arousal or other sexual pleasure, usually to the point of orgasm. The stimulation may involve hands, fingers, everyday objects, sex toys such as vibrators, or combinations of these. Mutual masturbation is masturbation with a sexual partner, and may include manual stimulation of a partner's genitals ( fingering or a handjob), or be used as a form of non-penetrative sex. Masturbation is frequent in both sexes and at any age. Various medical and psychological benefits have been attributed to a healthy attitude toward sexual activity in general and to masturbation in particular. No causal relationship is known between masturbation and any form of mental or physical disorder. In the Western world, masturbation in private or with a partner is generally considered a normal and healthy part of sexual enjoyment. Masturbation has been depicted in art since prehistoric times, and is both mentioned and discussed in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orgasm
Orgasm (from Greek , ; "excitement, swelling") or sexual climax is the sudden discharge of accumulated sexual excitement during the sexual response cycle, resulting in rhythmic, involuntary muscular contractions in the pelvic region characterized by sexual pleasure.Se133–135 for orgasm information, anpage 76for G-spot and vaginal nerve ending information. Experienced by males and females, orgasms are controlled by the involuntary or autonomic nervous system. They are usually associated with involuntary actions, including muscular spasms in multiple areas of the body, a general euphoric sensation and, frequently, body movements and vocalizations. The period after orgasm (known as the refractory period) is typically a relaxing experience, attributed to the release of the neurohormones oxytocin and prolactin as well as endorphins (or "endogenous morphine"). Human orgasms usually result from physical sexual stimulation of the penis in males (typically accompanying ejaculat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sexual Intercourse
Sexual intercourse (or coitus or copulation) is a sexual activity typically involving the insertion and thrusting of the penis into the vagina for sexual pleasure or reproduction.Sexual intercourse most commonly means penile–vaginal penetration for sexual pleasure or sexual reproduction; dictionary sources state that it especially means this, and scholarly sources over the years agree. See, for example; * * * * * * * * * This is also known as vaginal intercourse or vaginal sex. Other forms of penetrative sexual intercourse include anal sex (penetration of the anus by the penis), oral sex (penetration of the mouth by the penis or oral penetration of the female genitalia), fingering (sexual penetration by the fingers) and penetration by use of a dildo (especially a strap-on dildo). These activities involve physical intimacy between two or more individuals and are usually used among humans solely for physical or emotional pleasure and can contribute to human bonding. Ther ...

Photosynthesis
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities. Some of this chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are synthesized from carbon dioxide and water – hence the name ''photosynthesis'', from the Greek ''phōs'' (), "light", and ''synthesis'' (), "putting together". Most plants, algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth. Although photosynthesis is performed differently by different species, the process always begins when energy from light is absorbed by proteins called reaction centers that contain green chlorophyll (and other colored) pigments/chromoph ...

Social Constructionism
Social constructionism is a theory in sociology, social ontology, and communication theory which proposes that certain ideas about physical reality arise from collaborative consensus, instead of pure observation of said reality. The theory centers on the notion that meanings are developed in coordination with others rather than separately by each individual. It has often been characterised as neo- Marxian or also as a neo-Kantian theory, in that social constructionism replaces the transcendental subject with a concept of society that is at the same time descriptive and normative. While some social constructs are obvious, for instance money or the concept of currency, in that people have agreed to give it importance/value, others are controversial and hotly debated, such as the concept of self/self-identity. This articulates the view that people in society construct ideas or concepts that may not exist without the existence of people or language to validate those concepts. ...

Sexual Norm
A sexual norm can refer to a personal or a social norm. Most cultures have social norms regarding sexuality, and define ''normal sexuality'' to consist only of certain sex acts between individuals who meet specific criteria of age, consanguinity (e.g. incest), race/ethnicity (e.g. miscegenation), and/or social role and socioeconomic status. In most societies, the term ''normal'' identifies a range or spectrum of behaviors. Rather than each act being simply classified as "acceptable" or "not acceptable", many acts are viewed as "more or less accepted" by different people, and the opinion on how normal or acceptable they are greatly depends on the individual making the opinion as well as the culture itself. Based on information gained from sexological studies, a great many ordinary people's sex lives are very often quite different from popular beliefs about ''normal'', in private. If non-restrictive sexual norms are regarded positively, they may be called "sexual freedom", "sexua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
