Philosophy ('love of wisdom' in Ancient Greek) is a systematic study of general and fundamental questions concerning topics like existence, reason, knowledge, value, mind, and language. It is a rational and critical inquiry that reflects on its methods and assumptions.
Historically, many of the individual sciences, such as physics and psychology, formed part of philosophy. However, they are considered separate academic disciplines in the modern sense of the term. Influential traditions in the history of philosophy include Western, Arabic–Persian, Indian, and Chinese philosophy. Western philosophy originated in Ancient Greece and covers a wide area of philosophical subfields. A central topic in Arabic–Persian philosophy is the relation between reason and revelation. Indian philosophy combines the spiritual problem of how to reach enlightenment with the exploration of the nature of reality and the ways of arriving at knowledge. Chinese philosophy focuses principally on practical issues about right social conduct, government, and self-cultivation.

Anarky is an anti hero appearing in American comic books published by DC Comics. Co-created by Alan Grant and Norm Breyfogle, he first appeared in Detective Comics #608 (November 1989), as an adversary of Batman. Anarky is introduced as Lonnie Machin, a child prodigy with knowledge of radical philosophy and driven to overthrow governments to improve social conditions. Stories revolving around Anarky often focus on political and philosophical themes. The character, who is named after the philosophy of anarchism, primarily espouses anti-statism and attacks capitalism; however, multiple social issues have been addressed through the character, including environmentalism, antimilitarism, economic inequality, and political corruption. Inspired by multiple sources, early stories featuring the character often included homages to political and philosophical texts, and referenced anarchist philosophers and theorists. The inspiration for the creation of the character and its early development was based in Grant's personal interest in anti-authoritarian philosophy and politics. However, when Grant himself transitioned to the philosophy of Neo-Tech developed by Frank R. Wallace, he shifted the focus of Anarky from a vehicle for social anarchism and then libertarian socialism, with an emphasis on wealth redistribution and critique of Capitalism, to themes of individualism and personal reflections on the nature of consciousness.
Originally intended to only be used in the debut story in which he appeared, Grant decided to continue using Anarky as a sporadically recurring character throughout the early 1990s, following positive reception by readers and Dennis O'Neil. The character experienced a brief surge in media exposure during the late 1990s when Breyfogle convinced Grant to produce a limited series based on the character. The 1997 spin-off series, Anarky, was received with positive reviews and sales, and later declared by Grant to be among his "career highlights". Batman: Anarky, a trade paperback collection of stories featuring the character, soon followed. This popular acclaim culminated, however, in a financially and critically unsuccessful ongoing solo series. The 1999 Anarky series, for which even Grant has expressed his distaste, was quickly canceled after eight issues. (Full article...)

In political philosophy, a throffer is a proposal (also called an intervention) that mixes an offer with a threat which will be carried out if the offer is not accepted. The term was first used in print by political philosopher Hillel Steiner; while other writers followed, it has not been universally adopted and it is sometimes considered synonymous with carrot and stick. Though the threatening aspect of a throffer need not be obvious, or even articulated at all, an overt example is: "Kill this man and receive £100; fail to kill him and I'll kill you."
Steiner differentiated offers, threats and throffers based on the preferability of compliance and noncompliance for the subject when compared to the normal course of events that would have come about were no intervention made. Steiner's account was criticised by philosopher Robert Stevens, who instead suggested that what was important in differentiating the kinds of intervention was whether performing or not performing the requested action was more or less preferable than it would have been were no intervention made. Throffers form part of the wider moral and political considerations of coercion, and form part of the question of the possibility of coercive offers. Contrary to received wisdom that only threats can be coercive, throffers lacking explicit threats have been cited as an example of coercive offers, while some writers argue that offers, threats and throffers may all be coercive if certain conditions are met. For others, by contrast, if a throffer is coercive, it is explicitly the threat aspect that makes it so, and not all throffers can be considered coercive. (Full article...)

Conatus is, for Baruch Spinoza, where "each thing, as far as it lies in itself, strives to persevere in its being." In the philosophy of Baruch Spinoza, conatus (/koʊˈneɪtəs/; wikt:conatus; Latin for "effort; endeavor; impulse, inclination, tendency; undertaking; striving") is an innate inclination of a thing to continue to exist and enhance itself. This thing may be mind, matter, or a combination of both, and is often associated with God's will in a pantheist view of nature. The conatus may refer to the instinctive will to live of living organisms or to various metaphysical theories of motion and inertia. Today, conatus is rarely used in the technical sense, since classical mechanics uses concepts such as inertia and conservation of momentum that have superseded it. It has, however, been a notable influence on later thinkers such as Arthur Schopenhauer and Friedrich Nietzsche. (Full article...)
Ion Heliade Rădulescu or Ion Heliade (also known as Eliade or Eliade Rădulescu; Romanian pronunciation:[ˈi.onheliˈaderəduˈlesku]; 6 January 1802 – 27 April 1872) was a Wallachian, later Romanian academic, Romantic and Classicist poet, essayist, memoirist, short story writer, newspaper editor and politician. A prolific translator of foreign literature into Romanian, he was also the author of books on linguistics and history. For much of his life, Heliade Rădulescu was a teacher at Saint Sava College in Bucharest, which he helped reopen. He was a founding member and first president of the Romanian Academy.
Heliade Rădulescu is considered one of the foremost champions of Romanian culture from the first half of the 19th century, having first risen to prominence through his association with Gheorghe Lazăr and his support of Lazăr's drive for discontinuing education in Greek. Over the following decades, he had a major role in shaping the modern Romanian language, but caused controversy when he advocated the massive introduction of Italianneologisms into the Romanian lexis. A Romantic nationalist landowner siding with moderate liberals, Heliade was among the leaders of the 1848 Wallachian revolution, after which he was forced to spend several years in exile. Adopting an original form of conservatism, which emphasized the role of the aristocratic boyars in Romanian history, he was rewarded for supporting the Ottoman Empire and clashed with the radical wing of the 1848 revolutionaries.

Portrait by August Köhler, c. 1910, after 1627 original
Kepler was a mathematics teacher at a seminary school in Graz, where he became an associate of Prince Hans Ulrich von Eggenberg. Later he became an assistant to the astronomer Tycho Brahe in Prague, and eventually the imperial mathematician to Emperor Rudolf II and his two successors Matthias and Ferdinand II. He also taught mathematics in Linz, and was an adviser to General Wallenstein. Additionally, he did fundamental work in the field of optics, being named the father of modern optics, in particular for his Astronomiae pars optica. He also invented an improved version of the refracting telescope, the Keplerian telescope, which became the foundation of the modern refracting telescope, while also improving on the telescope design by Galileo Galilei, who mentioned Kepler's discoveries in his work. He is also known for postulating the Kepler conjecture. (Full article...)

Augustine of Hippo (AD 354–430) as painted by Sandro Botticelli (c. 1445–1510). Augustine is credited with developing the first form of the theodicy now named for him. The Augustinian theodicy, named for the 4th- and 5th-century theologian and philosopher Augustine of Hippo, is a type of Christiantheodicy that developed in response to the evidential problem of evil. As such, it attempts to explain the probability of an omnipotent (all-powerful) and omnibenevolent (all-loving) God amid evidence of evil in the world. A number of variations of this kind of theodicy have been proposed throughout history; their similarities were first described by the 20th-century philosopher John Hick, who classified them as "Augustinian". They typically assert that God is perfectly (ideally) good, that he created the world out of nothing, and that evil is the result of humanity's original sin. The entry of evil into the world is generally explained as consequence of original sin and its continued presence due to humans' misuse of free will and concupiscence. God's goodness and benevolence, according to the Augustinian theodicy, remain perfect and without responsibility for evil or suffering.
Augustine of Hippo was the first to develop the theodicy. He rejected the idea that evil exists in itself, instead regarding it as a corruption of goodness, caused by humanity's abuse of free will. Augustine believed in the existence of a physical Hell as a punishment for sin, but argued that those who choose to accept the salvation of Jesus Christ will go to Heaven. In the 13th century, Thomas Aquinas – influenced by Augustine – proposed a similar theodicy based on the view that God is goodness and that there can be no evil in him. He believed that the existence of goodness allows evil to exist, through the fault of humans. Augustine also influenced John Calvin, who supported Augustine's view that evil is the result of free will and argued that sin corrupts humans, requiring God's grace to give moral guidance.

Title page from the second edition of A Vindication of the Rights of Men, the first to carry Wollstonecraft's name
Wollstonecraft attacked not only hereditary privilege, but also the rhetoric that Burke used to defend it. Most of Burke's detractors deplored what they viewed as his theatrical pity for Marie Antoinette, but Wollstonecraft was unique in her love of Burke's gendered language. By saying the sublime and the beautiful, terms first established by Burke himself in A Philosophical Enquiry into the Origin of Our Ideas of the Sublime and Beautiful (1756), she kept his rhetoric as well as his argument. In her first unabashedly feminist critique, which Wollstonecraft scholar Claudia Johnson describes as unsurpassed in its argumentative force, Wollstonecraft indicts Burke's justification of an equal society founded on the passivity of women.

The title-page of the 1759 edition published by Cramer in Geneva, which reads, "Candide, or Optimism, translated from German by Dr. Ralph."
Candide, ou l'Optimisme (/kɒnˈdiːd/kon-DEED, French:[kɑ̃did]ⓘ) is a French satire written by Voltaire, a philosopher of the Age of Enlightenment, first published in 1759. The novella has been widely translated, with English versions titled Candide: or, All for the Best (1759); Candide: or, The Optimist (1762); and Candide: Optimism (1947). A young man, Candide, lives a sheltered life in an Edenicparadise, being indoctrinated with Leibnizian optimism by his mentor, Professor Pangloss. This lifestyle is abruptly ended, followed by Candide's slow and painful disillusionment as he witnesses and experiences great hardships in the world. Voltaire concludes Candide with, if not rejecting Leibnizian optimism outright, advocating a deeply practical precept, "we must cultivate our garden", in lieu of the Leibnizian mantra of Pangloss, "all is for the best" in the "best of all possible worlds".
Candide is characterized by its tone as well as its erratic, fantastical, and fast-moving plot. A picaresque novel with a story akin to a serious bildungsroman, it parodies many adventure and romance clichés, in a tone that is bitter and matter-of-fact. The events discussed are often based on historical happenings. As philosophers of Voltaire's day contended with the problem of evil, so does Candide, albeit more directly and humorously. Voltaire ridicules religion, theologians, governments, armies, philosophies, and philosophers. Through Candide, he assaults Leibniz and his optimism. (Full article...)

Why Marx Was Right is a 2011 non-fiction book by the British academic Terry Eagleton about the 19th-century philosopher Karl Marx and the schools of thought, collectively known as Marxism, that arose from his work. Written for laypeople, Why Marx Was Right outlines ten objections to Marxism that they may hold and aims to refute each one in turn. These include arguments that Marxism is irrelevant owing to changing social classes in the modern world, that it is deterministic and utopian, and that Marxists oppose all reforms and believe in an authoritarian state.
In his counterarguments, Eagleton explains how class struggle is central to Marxism, and that history is seen as a progression of modes of production, like feudalism and capitalism, involving the materials, technology and social relations required to produce goods and services within the society. Under a capitalist economy, the working class, known as the proletariat, are those lacking significant autonomy over their labour conditions, and have no control over the means of production. Eagleton describes how revolutions could lead to a new mode of production—socialism—in which the working class have control, and an eventual communist society could make the state obsolete. He explores the failures of the Soviet Union and other Marxist–Leninist countries. (Full article...)

Anekāntavāda (Sanskrit: अनेकान्तवाद, "many-sidedness", Tamil: பல்லுரை, romanized: pallurai) is the Jain doctrine about metaphysical truths that emerged in ancient India. It states that the ultimate truth and reality is complex and has multiple aspects and viewpoints.
According to Jainism, no single, specific statement can describe the nature of existence and the absolute truth. This knowledge (Kevala Jnana), it adds, is comprehended only by the Arihants. Other beings and their statements about absolute truth are incomplete, and at best a partial truth. All knowledge claims, according to the anekāntavāda doctrine must be qualified in many ways, including being affirmed and denied. Anekāntavāda is a fundamental doctrine of Jainism. (Full article...)
Text below: "The 'pink triangle' was the sign with which the National Socialists marked homosexuals in the concentration camps in a defamatory way. From January 1933 almost all homosexual locales in and around Nollendorfplatz were closed by the National Socialists or misused by raids to create 'pink lists' (homosexual files)."
The Nazi regime considered the elimination of all manifestations of homosexuality in Germany one of its goals. Men were often arrested after denunciation, police raids, and through information uncovered during interrogations of other homosexuals. Those arrested were presumed guilty, and subjected to harsh interrogation and torture to elicit a confession. Between 1933 and 1945, an estimated 100,000 men were arrested as homosexuals; around 50,000 of these were sentenced by civilian courts, 6,400 to 7,000 by military courts [de], and an unknown number by special courts. Most of these men served time in regular prisons, and between 5,000 and 6,000 were imprisoned in concentration camps. The death rate of these prisoners has been estimated at 60 percent, a higher rate than those of other prisoner groups. A smaller number of men were sentenced to death or killed at Nazi euthanasia centres. Nazi Germany's persecution of homosexuals is considered to be the most severe episode in a long history of discrimination and violence targeting sexual minorities. (Full article...)

Confirmation bias (also confirmatory bias, myside bias, or congeniality bias) is the tendency to search for, interpret, favor, and recall information in a way that confirms or supports one's prior beliefs or values. People display this bias when they select information that supports their views, ignoring contrary information, or when they interpret ambiguous evidence as supporting their existing attitudes. The effect is strongest for desired outcomes, for emotionally charged issues, and for deeply entrenched beliefs.
Biased search for information, biased interpretation of this information, and biased memory recall, have been invoked to explain four specific effects:
attitude polarization (when a disagreement becomes more extreme even though the different parties are exposed to the same evidence)
belief perseverance (when beliefs persist after the evidence for them is shown to be false)
the irrational primacy effect (a greater reliance on information encountered early in a series)
illusory correlation (when people falsely perceive an association between two events or situations).
Wallace did extensive fieldwork, starting in the Amazon River basin. He then did fieldwork in the Malay Archipelago, where he identified the faunal divide now termed the Wallace Line, which separates the Indonesian archipelago into two distinct parts: a western portion in which the animals are largely of Asian origin, and an eastern portion where the fauna reflect Australasia. He was considered the 19th century's leading expert on the geographical distribution of animal species, and is sometimes called the "father of biogeography", or more specifically of zoogeography.

Selected philosopher of the week
Martin Heidegger, was the German philosopher who wrote Being and Time. He was one of the most influential philosophers of the 20th century, and his ideas have penetrated into many areas. His discussion of ontology has led to his being often cited as one of the founders of existentialism. His ideas inspired major philosophical works, e.g., Sartre's Being and Nothingness, although Heidegger insisted that Sartre misunderstood him. His philosophical work was taken up throughout Germany, France, and Japan and has gained, since the 1970s, a fair following in North America as well. Heidegger's work was scorned and dismissed, however, by many of his contemporaries, such as the Vienna Circle, Theodor Adorno, the Hegelians, and Anglo-American philosophers such as Bertrand Russell and A. J. Ayer.
Hippocrates of Cos or Hippokrates of Kos (ca. 460 BC – ca. 370 BC) - Greek: Ἱπποκράτης; Hippokrátēs was an ancient Greekphysician of the Age of Pericles (Classical Athens), and is considered one of the most outstanding figures in the history of medicine. He is referred to as the Western father of medicine in recognition of his lasting contributions to the field as the founder of the Hippocratic School of medicine. This intellectual school revolutionized medicine in ancient Greece, establishing it as a discipline distinct from other fields that it had traditionally been associated with (notably theurgy and philosophy), thus making medicine a profession.
However, the achievements of the writers of the Corpus, the practitioners of Hippocratic medicine, and the actions of Hippocrates himself are often commingled; thus very little is known about what Hippocrates actually thought, wrote, and did. Nevertheless, Hippocrates is commonly portrayed as the paragon of the ancient physician. In particular, he is credited with greatly advancing the systematic study of clinical medicine, summing up the medical knowledge of previous schools, and prescribing practices for physicians through the Hippocratic Oath, Corpus and other works.
The illusory truth effect (also known as the illusion of truth effect, validity effect, truth effect, or the reiteration effect) is the tendency to believe false information to be correct after repeated exposure. This phenomenon was first identified in a 1977 study at Villanova University and Temple University. When truth is assessed, people rely on whether the information is in line with their understanding or if it feels familiar. The first condition is logical, as people compare new information with what they already know to be true. Repetition makes statements easier to process relative to new, unrepeated statements, leading people to believe that the repeated conclusion is more truthful. The illusory truth effect has also been linked to hindsight bias, in which the recollection of confidence is skewed after the truth has been received.
In a 2015 study, researchers discovered that familiarity can overpower rationality and that repetitively hearing that a certain statement is wrong can paradoxically cause it to feel right. Researchers observed the illusory truth effect's impact even on participants who knew the correct answer to begin with but were persuaded to believe otherwise through the repetition of a falsehood, to "processing fluency".

The Iranian Enlightenment (Persian: روشنگری ایرانی), sometimes called the first generation of intellectual movements in Iran (Persian: نسل اول جنبش های روشنفکری در ایران), brought new ideas into traditional Iranian society from the mid-nineteenth to the early twentieth century. During the rule of the Qajar dynasty, and especially after the defeat of Iran in its war with the Russian Empire, cultural exchanges led to the formation of new ideas among the educated class of Iran.The establishment of Dar ul-Fonun, the first modern university in Iran and the arrival of foreign professors, caused the thoughts of European thinkers to enter Iran, followed by the first signs of enlightenment and intellectual movements in Iran.
During this period, intellectual groups were formed in secret societies and secret associations. These secret societies included Mirza Malkam Khan's Faramosh Khaneh (based on Masonic lodges), Anjoman-e Okhovat, Society of Humanity and Mokhadarat Vatan Association. These groups spread their ideas by distributing leaflets and newspapers. These secret societies stressed the need to reform the land and administrative system and reduce the role of the clergy in society, as well as to limit the rulers within the framework of the law.

According to different scholars, the history of anarchism either goes back to ancient and prehistoric ideologies and social structures, or begins in the 19th century as a formal movement. As scholars and anarchist philosophers have held a range of views on what anarchism means, it is difficult to outline its history unambiguously. Some feel anarchism is a distinct, well-defined movement stemming from 19th-century class conflict, while others identify anarchist traits long before the earliest civilisations existed.
Prehistoric society existed without formal hierarchies, which some anthropologists have described as similar to anarchism. The first traces of formal anarchist thought can be found in ancient Greece and China, where numerous philosophers questioned the necessity of the state and declared the moral right of the individual to live free from coercion. During the Middle Ages, some religious sects espoused libertarian thought, and the Age of Enlightenment, and the attendant rise of rationalism and science, signalled the birth of the modern anarchist movement.

Aurobindo studied for the Indian Civil Service at King's College, in Cambridge, England. After returning to India he took up various civil service works under the Maharaja of the princely state of Baroda and became increasingly involved in nationalist politics in the Indian National Congress and the nascent revolutionary movement in Bengal with the Anushilan Samiti. He was arrested in the aftermath of a number of bombings linked to his organization in a public trial where he faced charges of treason for Alipore Conspiracy. However, Sri Aurobindo could only be convicted and imprisoned for writing articles against British colonial rule in India. He was released when no evidence could be provided, following the murder of a prosecution witness, Narendranath Goswami, during the trial. During his stay in the jail, he had mystical and spiritual experiences, after which he moved to Pondicherry, leaving politics for spiritual work. (Full article...)

Marcellina was an early ChristianCarpocratian religious leader in the mid-second century AD known primarily from the writings of Irenaeus and Origen. She originated in Alexandria, but moved to Rome during the episcopate of Anicetus (c. 157 – 168). She attracted large numbers of followers and founded the Carpocratian sect of Marcellians. Like other Carpocratians, Marcellina and her followers believed in antinomianism, also known as libertinism, the idea that obedience to laws and regulations is unnecessary in order to attain salvation. They believed that Jesus was only a man, but saw him as a model to be emulated, albeit one which a believer was capable of surpassing. Marcellina's community appears to have sought to literally implement the foundational Carpocratian teaching of social egalitarianism. The Marcellians in particular are reported to have branded their disciples on the insides of their right earlobes and venerated images of Jesus as well as Greek philosophers such as Pythagoras, Plato, and Aristotle. Although the Marcellians identified themselves as "gnostics", many modern scholars do not classify them as members of the sect of Gnosticism. (Full article...)

Plaque with the five precepts engraved in English, Lumbini, Nepal
The five precepts (Sanskrit: pañcaśīla; Pali: pañcasīla) or five rules of training (Sanskrit: pañcaśikṣapada; Pali: pañcasikkhapada) is the most important system of morality for Buddhist lay people. They constitute the basic code of ethics to be respected by lay followers of Buddhism. The precepts are commitments to abstain from killing living beings, stealing, sexual misconduct, lying and intoxication. Within the Buddhist doctrine, they are meant to develop mind and character to make progress on the path to enlightenment. They are sometimes referred to as the Śrāvakayāna precepts in the Mahāyāna tradition, contrasting them with the bodhisattva precepts. The five precepts form the basis of several parts of Buddhist doctrine, both lay and monastic. With regard to their fundamental role in Buddhist ethics, they have been compared with the Ten Commandments in Abrahamic religions or the ethical codes of Confucianism. The precepts have been connected with utilitarianist, deontological and virtue approaches to ethics, though by 2017, such categorization by western terminology had mostly been abandoned by scholars. The precepts have been compared with human rights because of their universal nature, and some scholars argue they can complement the concept of human rights.
The five precepts were common to the religious milieu of 6th-century BCE India, but the Buddha's focus on awareness through the fifth precept was unique. As shown in Early Buddhist Texts, the precepts grew to be more important, and finally became a condition for membership of the Buddhist religion. When Buddhism spread to different places and people, the role of the precepts began to vary. In countries where Buddhism had to compete with other religions, such as China, the ritual of undertaking the five precepts developed into an initiation ceremony to become a Buddhist layperson. On the other hand, in countries with little competition from other religions, such as Thailand, the ceremony has had little relation to the rite of becoming Buddhist, as many people are presumed Buddhist from birth.

Cries and Whispers (Swedish: Viskningar och rop, lit. 'Whispers and Cries') is a 1972 Swedish period drama film written and directed by Ingmar Bergman and starring Harriet Andersson, Kari Sylwan, Ingrid Thulin and Liv Ullmann. The film, set in a mansion at the end of the 19th century, is about three sisters and a servant who struggle with the terminal cancer of one of the sisters (Andersson). The servant (Sylwan) is close to her, while the other two sisters (Ullmann and Thulin) confront their emotional distance from each other.
Inspired by Bergman's mother, Karin Åkerblom, and his vision of four women in a red room, Cries and Whispers was filmed at Taxinge-Näsby Castle in 1971. Its themes include faith, the female psyche and the search for meaning in suffering, and academics have found Biblical allusions. Unlike previous Bergman films, it uses saturated colour, crimson in particular. (Full article...)

Vyāsatīrtha (c. 1460 – c. 1539), also called Vyasaraja or Chandrikacharya, was a Hinduphilosopher, scholar, polemicist, commentator and poet belonging to the Madhwacharya's Dvaita order of Vedanta. As the rajaguru of Vijayanagara Empire, Vyasatirtha was at the forefront of a golden age in Dvaita which saw new developments in dialectical thought, growth of the Haridasa literature under bards like Purandara Dasa and Kanaka Dasa and an increased spread of Dvaita across the subcontinent. He himself composed many kīrtanas in Kannada and Sanskrit.
Three of his polemically themed doxographical works Nyayamruta, Tatparya Chandrika and Tarka Tandava (collectively called Vyasa Traya) documented and critiqued an encyclopaedic range of sub-philosophies in Advaita, Visistadvaita, Mahayana Buddhism, Mimamsa and Nyaya, revealing internal contradictions and fallacies. His Nyayamruta caused a stir in the Advaita community across the country requiring a rebuttal by Madhusudhana Saraswati through his text, Advaitasiddhi. He is considered as an amsha of Prahlada in the Madhva Parampara. (Full article...)

The Butterfly Dream, by Chinese painter Lu Zhi (c. 1550)
The Zhuangzi (historically romanized Chuang Tzŭ) is an ancient Chinese text that is one of the two foundational texts of Taoism, alongside the Tao Te Ching. It was written during the late Warring States period (476–221 BC) and is named for its traditional author, Zhuang Zhou, who is customarily known as "Zhuangzi" ("Master Zhuang").
The Zhuangzi consists of stories and maxims that exemplify the nature of the ideal Taoist sage. It contains numerous anecdotes, allegories, parables, and fables, often expressed with irreverence or humor. Recurring themes include embracing spontaneity and achieving freedom from the human world and its conventions. The text aims to illustrate the arbitrariness and ultimate falsity of dichotomies normally embraced by human societies, such as those between good and bad, large and small, life and death, or human and nature. In contrast with the focus on good morals and personal duty expressed by many Chinese philosophers of the period, Zhuang Zhou promoted carefree wandering and following nature, through which one would ultimately become one with the "Way" (Tao).

With the publication of "A Dynamical Theory of the Electromagnetic Field" in 1865, Maxwell demonstrated that electric and magnetic fields travel through space as waves moving at the speed of light. He proposed that light is an undulation in the same medium that is the cause of electric and magnetic phenomena. The unification of light and electrical phenomena led to his prediction of the existence of radio waves, and the paper contained his final version of his equations, which he had been working on since 1856. As a result of his equations, and other contributions such as introducing an effective method to deal with network problems and linear conductors, he is regarded as a founder of the modern field of electrical engineering. In 1871, Maxwell became the first Cavendish Professor of Physics, serving until his death in 1879. (Full article...)

The Kingdom of This World (Spanish: El reino de este mundo) is a novel by Cuban author Alejo Carpentier, published in 1949 in his native Spanish and first translated into English in 1957. A work of historical fiction, it tells the story of Haiti before, during, and after the Haitian Revolution led by Toussaint Louverture, as seen by its central character, Ti Noel, who serves as the novel's connecting thread. Carpentier's work has been influenced by his multi-cultural experience and his passion for the arts, as well as by authors such as Miguel de Cervantes. The novel stems from the author's desire to retrace the roots and history of the New World, and is embedded with what Carpentier calls "lo real maravilloso" or "the marvelous real"—a concept he introduced to the world of literature (not to be confused with magical realism).
Throughout the novel, varying perceptions of reality that arise due to cultural differences between its characters are emphasized and contrasted. Carpentier explores hybridization, nature, voodoo, ethnicity, history and destiny, confusion, violence, and sexuality in a style that blends history with fiction and uses repetition to emphasize the cyclical nature of events. The novel was largely well-received with much attention paid to Carpentier's inclusion of magic realism and The Kingdom of This World has been described as an important work in the development of this genre in Caribbean and Latin American literature. However, some technical aspects of his style have been ignored by the academic community, and the novel's narrative organization has been criticized. (Full article...)

The hand signal "OK" Diver communications are the methods used by divers to communicate with each other or with surface members of the dive team. In professional diving, diver communication is usually between a single working diver and the diving supervisor at the surface control point. This is considered important both for managing the diving work, and as a safety measure for monitoring the condition of the diver. The traditional method of communication was by line signals, but this has been superseded by voice communication, and line signals are now used in emergencies when voice communications have failed. Surface supplied divers often carry a closed circuit video camera on the helmet which allows the surface team to see what the diver is doing and to be involved in inspection tasks. This can also be used to transmit hand signals to the surface if voice communications fails. Underwater slates may be used to write text messages which can be shown to other divers, and there are some dive computers which allow a limited number of pre-programmed text messages to be sent through-water to other divers or surface personnel with compatible equipment.
Communication between divers and between surface personnel and divers is imperfect at best, and non-existent at worst, as a consequence of the physical characteristics of water. This prevents divers from performing at their full potential. Voice communication is the most generally useful format underwater, as visual forms are more affected by visibility, and written communication and signing are relatively slow and restricted by diving equipment.

Wave functions of the electron in a hydrogen atom at different energy levels. Quantum mechanics cannot predict the exact location of a particle in space, only the probability of finding it at different locations. The brighter areas represent a higher probability of finding the electron. Quantum mechanics is a fundamental theory that describes the behavior of nature at and below the scale of atoms. It is the foundation of all quantum physics, which includes quantum chemistry, quantum field theory, quantum technology, and quantum information science.
Quantum mechanics can describe many systems that classical physics cannot. Classical physics can describe many aspects of nature at an ordinary (macroscopic and (optical) microscopic) scale, but is not sufficient for describing them at very small submicroscopic (atomic and subatomic) scales. Most theories in classical physics can be derived from quantum mechanics as an approximation, valid at large (macroscopic/microscopic) scale. (Full article...)

Philosophy ponders the most fundamental questions humankind has been able to ask. These are increasingly numerous and over time they have been arranged into the overlapping branches of the philosophy tree:
Aesthetics: What is art? What is beauty? Is there a standard of taste? Is art meaningful? If so, what does it mean? What is good art? Is art for the purpose of an end, or is "art for art's sake?" What connects us to art? How does art affect us? Is some art unethical? Can art corrupt or elevate societies?
Epistemology: What are the nature and limits of knowledge? What is more fundamental to human existence, knowing (epistemology) or being (ontology)? How do we come to know what we know? What are the limits and scope of knowledge? How can we know that there are other minds (if we can)? How can we know that there is an external world (if we can)? How can we prove our answers? What is a true statement?
Ethics: Is there a difference between ethically right and wrong actions (or values, or institutions)? If so, what is that difference? Which actions are right, and which wrong? Do divine commands make right acts right, or is their rightness based on something else? Are there standards of rightness that are absolute, or are all such standards relative to particular cultures? How should I live? What is happiness?
Logic: What makes a good argument? How can I think critically about complicated arguments? What makes for good thinking? When can I say that something just does not make sense? Where is the origin of logic?
Metaphysics: What sorts of things exist? What is the nature of those things? Do some things exist independently of our perception? What is the nature of space and time? What is the relationship of the mind to the body? What is it to be a person? What is it to be conscious? Do gods exist?
Political philosophy: Are political institutions and their exercise of power justified? What is justice? Is there a 'proper' role and scope of government? Is democracy the best form of governance? Is governance ethically justifiable? Should a state be allowed? Should a state be able to promote the norms and values of a certain moral or religious doctrine? Are states allowed to go to war? Do states have duties against inhabitants of other states?
