Autodidacticism (also autodidactism) or self-education (also self-learning and self-teaching) is education without the guidance of masters (such as teachers and professors) or institutions (such as schools). Generally, an autodidact is an individual who chooses the subject they will study, their studying material, and the studying rhythm and time. An autodidact may or may not have formal education, and their study may be either a complement or an alternative to formal education. Many notable contributions have been made by autodidacts.

Boids is an artificial life program, developed by Craig Reynolds in 1986, which simulates the flocking behaviour of birds. His paper on this topic was published in 1987 in the proceedings of the ACM SIGGRAPH conference. The name "boid" corresponds to a shortened version of "bird-oid object", which refers to a bird-like object. Incidentally, "boid" is also a New York Metropolitan dialect pronunciation for "bird".

As with most artificial life simulations, Boids is an example of emergent behavior; that is, the complexity of Boids arises from the interaction of individual agents (the boids, in this case) adhering to a set of simple rules. The rules applied in the simplest Boids world are as follows:

• separation: steer to avoid crowding local flockmates
• alignment: steer towards the average heading of local flockmates
• cohesion: steer to move towards the average position (center of mass) of local flockmates

More complex rules can be added, such as obstacle avoidance and goal seeking.

The basic model has been extended in several different ways since Reynolds proposed it. For instance, Delgado-Mata et al. extended the basic model to incorporate the effects of fear. Olfaction was used to transmit emotion between animals, through pheromones modelled as particles in a free expansion gas. Hartman and Benes introduced a complementary force to the alignment that they call the change of leadership. This steer defines the chance of the boid to become a leader and try to escape.

The movement of Boids can be characterized as either chaotic (splitting groups and wild behaviour) or orderly. Unexpected behaviours, such as splitting flocks and reuniting after avoiding obstacles, can be considered emergent.

The boids framework is often used in computer graphics, providing realistic-looking representations of flocks of birds and other creatures, such as schools of fish or herds of animals. It was for instance used in the 1998 video game Half-Life for the flying bird-like creatures seen at the end of the game on Xen, named "boid" in the game files.

The Boids model can be used for direct control and stabilization of teams of simple Unmanned Ground Vehicles (UGV) or Micro Aerial Vehicles (MAV) in swarm robotics. For stabilization of heterogeneous UAV-UGV teams, the model was adapted for using onboard relative localization by Saska et al.

At the time of proposal, Reynolds' approach represented a giant step forward compared to the traditional techniques used in computer animation for motion pictures. The first animation created with the model was Stanley and Stella in: Breaking the Ice (1987), followed by a feature film debut in Tim Burton's film Batman Returns (1992) with computer generated bat swarms and armies of penguins marching through the streets of Gotham City.

The boids model has been used for other interesting applications. It has been applied to automatically program Internet multi-channel radio stations. It has also been used for visualizing information and for optimization tasks.

🔗 Novels

The 480 is a political fiction novel by Eugene Burdick (1964).

The plot evolves around the political turmoil after John F. Kennedy assassination in 1963. In the novel, a fictitious charismatic character, John Thatch, an engineer, is seeking nomination for the Republican Party candidate at 1964 presidential elections. He is described as being contaminated with the "political virus". A handful of political professionals are promoting his nomination, in confrontation with the Party establishment. There exist apparent parallels between Thatch and Henry Cabot Lodge, Jr., a write-in hero at New Hampshire primary.

The novel criticizes the socio-political effects on society at large from the use of computers to run massive simulations, which predict the public reaction to certain (proposed) political moves before implementing them. Such simulations make it easy to manipulate the public consciousness.

The "480" in the title denotes the number of groups (by party affiliation, socioeconomic status, location, origin, etc.) that the computer simulation uses to classify the American electorate. The full list of these is reproduced in the Appendix, claimed by the author to be the true list used by the Simulmatics Corporation (real name) in Senator John F. Kennedy's Presidential campaign in 1960. The cover features an IBM 5081 punched card.

The Simulmatics Corporation was created by MIT Professor Ithiel de Sola Pool, who provided a non-fiction backup to "The 480" in "Candidates, Issues, and Strategies: A Computer Simulation of the 1960 Presidential Election," MIT Press, 1964 (with co-authors Robert P. Abelson and Samuel L. Popkin). They built their model from 130,000 archived interviews in Gallup and Roper polls over a ten-year period. Based on its output, they advised Kennedy that he would benefit from a strong civil rights stand and that he had nothing to lose, and much to gain, by attacking religious bigotry and dealing frankly with his Catholicism.

The 480 has been cited as prefiguring the effect of modern social media and data gathering on politics.

The Strauss–Howe generational theory, also known as the Fourth Turning theory or simply the Fourth Turning, which was created by authors William Strauss and Neil Howe, describes a theorized recurring generation cycle in American history. According to the theory, historical events are associated with recurring generational personas (archetypes). Each generational persona unleashes a new era (called a turning) lasting around 20–22 years, in which a new social, political, and economic climate exists. They are part of a larger cyclical "saeculum" (a long human life, which usually spans between 80 and 90 years, although some saecula have lasted longer). The theory states that after every saeculum, a crisis recurs in American history, which is followed by a recovery (high). During this recovery, institutions and communitarian values are strong. Ultimately, succeeding generational archetypes attack and weaken institutions in the name of autonomy and individualism, which ultimately creates a tumultuous political environment that ripens conditions for another crisis.

Strauss and Howe laid the groundwork for their theory in their 1991 book Generations, which discusses the history of the United States as a series of generational biographies going back to 1584. In their 1997 book The Fourth Turning, the authors expanded the theory to focus on a fourfold cycle of generational types and recurring mood eras to describe the history of the United States, including the Thirteen Colonies and their British antecedents. However, the authors have also examined generational trends elsewhere in the world and described similar cycles in several developed countries.

Academic response to the theory has been mixed—some applauding Strauss and Howe for their "bold and imaginative thesis" and others criticizing the theory as being overly-deterministic, non-falsifiable, and unsupported by rigorous evidence, "about as scientific as astrology or a Nostradamus text." Strauss–Howe generational theory has also been described by some historians and journalists as a "pseudoscience" "kooky", and "an elaborate historical horoscope that will never withstand scholarly scrutiny."

Academic criticism has focused on the lack of rigorous empirical evidence for their claims, and the authors' view that generational groupings are far more powerful than other social groupings such as economic class, race, sex, religion and political parties.

In marketing strategy, first-mover advantage (FMA) is the advantage gained by the initial ("first-moving") significant occupant of a market segment. First-mover advantage may be gained by technological leadership, or early purchase of resources.

A market participant has first-mover advantage if it is the first entrant and gains a competitive advantage through control of resources. With this advantage, first-movers can be rewarded with huge profit margins and a monopoly-like status.

Not all first-movers are rewarded. If the first-mover does not capitalize on its advantage, its "first-mover disadvantages" leave opportunity for new entrants to enter the market and compete more effectively and efficiently than the first-movers; such firms have "second-mover advantage".

🔗 Psychology

Cabin fever refers to the distressing claustrophobic irritability or restlessness experienced when a person, or group, is stuck at an isolated location or in confined quarters for an extended period of time. A person may be referred to as stir-crazy, derived from the use of stir to mean 'prison'.

A person may experience cabin fever in a situation such as being isolated within a vacation cottage out in the country, spending long periods underwater in a submarine, or being otherwise isolated from civilization. During cabin fever, a person may experience sleepiness or sleeplessness, have a distrust of anyone they are with, or have an urge to go outside even in adverse conditions such as poor weather or limited visibility. The concept is also invoked humorously to indicate simple boredom from being home alone for an extended period of time.

Cabin fever is not itself a disease and there is no prognosis. However, related symptoms can lead the sufferer to make irrational decisions that could potentially threaten their life or the life of the group with whom they are confined. Some examples would be suicide or paranoia, or leaving the safety of a cabin during a terrible snow storm that one may be stuck in.

The International Day of Happiness is celebrated worldwide every year on 20 March, and was originally conceptualized and founded in 2006 by Jayme Illien, CEO of the United Nations New World Order project, to advance happiness as a fundamental human right for all human beings, and happytalism, as new economic system, theory, and philosophy, which achieves the United Nations global goals, and the happiness, well-being, and freedom of all life on earth.

The next international day of happiness is March 20, 2021.

The 2020 International Day of Happiness campaign theme is ‘Happiness For All, Together'”. To celebrate, UNIDOHappiness, the UN secretariat for the International Day Of Happiness, is calling on all 7.8 billion people and all 206 nations and territories, to take the "Ten Steps to Global Happiness" challenge and call to action. The ten steps to global happiness are "ten easy steps any individual, organization, or country, can take on the international day of happiness, and throughout happiness week, to celebrate the international day of happiness, while also advancing the happiness, wellbeing, and freedom of all life on earth by 2050, when the United Nations forecasts global population to reach 10 billion". The first step is “Tell Everyone", which is designed "spread the word" to increase global awareness about the very existence of the international day of happiness, and the UN's unanimous recognition of happiness as a human right, as well as happiness as an approach to sustainable economic and human development.

The 2006 origin and inspiration for creating the international day of happiness initially came from founder Jayme Illien's belief that the happiness, wellbeing, and freedom of all life on earth is the ultimate purpose of every human being, nation, and society. Illien developed his vision for global happiness as humanity's ultimate purpose, through a life spent on the frontlines saving orphaned and abandoned children fleeing war, genocide, and extreme poverty, and theorizing about solutions to the human condition, and the great challenges facing humankind, after he himself was abandoned as an orphan, and rescued from a roadside in India in 1980, by missionaries of Mother Teresa, who first named him Adam, and sent him to live in America.

In 2006, Illien first presented the new economic theory, "happytalism", as a new economic system for the 21st century and beyond, to replace old world economic systems (from 5th to 20th century) such as capitalism, communism, socialism, mercantilism, colonialism, feudalism, racism, and sexism, among others - all created more than 150-1000 years ago. In 2006, Illien successfully demonstrated to prominent economists, academics, political scientists, philosophers, presidents, prime ministers, and heads of state, all in a position to advance happytalism as a solution to the great challenges facing humankind, that the new economic theory was the solution to the world's most pressing and greatest human development challenges and opportunities. However, despite Illien's successful proof of happytalism as a new economic system to replace capitalism and other old world, archaic, obsolete economic systems and models, this eminent multidisciplinary group of experts rejected the idea, and refused to further evaluate or consider the new economic theory due to what Illien, and co founder, Ndaba Mandela, believed were "old world and obsolete tyranny of the status quo, entrenched racist and sexist bias, mindset, incompetence, failed intelligence and intellectual vitality, and an archaic, potentially criminal world view that is a gross violation of global ethical norms, and implicit fiduciary responsibility to all humanity, incapable of seeing and doing what is right and necessary to advance humanity forward".

In 2008, in response to the rejection of Illien's concept of "happytalism" as a new economic theory, and convinced of happytalism as the solution to humanity's great challenges and opportunities in the 21st century and beyond, Illien launched the United Nations New World Order project with co founder Ndaba Mandela, grandson of Nelson Mandela, former president of South Africa, who led the revolution and movement that ended apartheid, and "gave birth to a new nation, a new political party, and a new era of democratic governance in South Africa, and the African Continent.". The United Nations New World Order Project launched in 2008 envisioned, among several UN based policy initiatives, the creation of a United Nations sanctioned "international day of happiness", as a global day of awareness that commemorates and recognizes happiness as a human right, and a fundamental, universal human goal, and calls for a new happiness centric human development paradigm which achieves the happiness, wellbeing, and freedom of all life on earth.

Illien drew inspiration for the idea of establishing the international day of happiness from the founders of the United States of America, and authors of the US Declaration of Independence, as well as, the founders of the United Nations, and UN Day, and the authors of the United Nations Charter. Illien believed that an "international day of happiness", established with, and recognized by, a new UN resolution, with the support of all 193 UN member countries, would provide the essential, unique, and broad-based, wide-ranging democratic support, international credibility, and worldwide legal legitimacy, for a new global day of happiness for humanity, which in turn, would enable future generations to eventually, objectively consider the concept of happytalism as a new economic system to solve to the great challenges facing humanity, thereby placing the fate and future of happytalism directly in the hands of the people and future generations.

In 2012, the United Nations General Assembly adopted UN resolution 66 281: International Day of Happiness with the unanimous consensus of all 193 Member States, and the support of then UN Secretary General Ban Ki moon, declaring March 20 as the international day of happiness. Illien chose 20 March for its significance as the March equinox, a universal phenomenon felt simultaneously by all of humankind.

In 2012, the United Nations also hosted the first high level meeting on Happiness and Well-being: Defining A New Economic Paradigm, at which UN Secretary General Ban Ki moon declared:

Later in 2012, then UN Secretary General Ban Ki moon stated in his closing remarks to the 66th session of the UN General Assembly:

On January 22, 2013, then UN Secretary General Ban Ki moon stated in an address to the UN General Assembly:

On March 20, 2013, the first ever international day of happiness was celebrated with the launch of UNIDOHappiness, and the "Ten Steps to Global Happiness" campaign theme, which has since become an annual tradition.

Every 20 March since 2013, the International Day of Happiness is celebrated in 193 UN Member states, 2 observer states, and 11 territories.

On the 3rd ever international day of happiness, UN Secretary Ban Ki moon said,

The Micronesian island of Yap is known for its stone money, known as Rai (Yapese: raay), or Fei: large doughnut-shaped, carved disks of (usually) calcite, up to 4 m (13 ft) in diameter (most are much smaller). The smallest can be as little as 3.5 centimetres (1.4 in) in diameter. There are around 6,000 of the large, circular stone disks carved out of limestone formed from aragonite and calcite crystals. Rai stones were quarried on several of the Micronesian islands, mainly Palau, but briefly on Guam as well, and transported to Yap for use as money. They have been used in trade by the Yapese as a form of currency.

The monetary system of Yap relies on an oral history of ownership. In the case of stones that are too large to move, buying an item with one simply involves agreeing that the ownership has changed. As long as the transaction is recorded in the oral history, it will now be owned by the person to whom it is passed and no physical movement of the stone is required.
