🔗 R/K selection theory

🔗 Evolutionary biology 🔗 Ecology

In ecology, r/K selection theory relates to the selection of combinations of traits in an organism that trade off between quantity and quality of offspring. The focus on either an increased quantity of offspring at the expense of individual parental investment of r-strategists, or on a reduced quantity of offspring with a corresponding increased parental investment of K-strategists, varies widely, seemingly to promote success in particular environments.

The terminology of r/K-selection was coined by the ecologists Robert MacArthur and E. O. Wilson in 1967 based on their work on island biogeography; although the concept of the evolution of life history strategies has a longer history (see e.g. plant strategies).

The theory was popular in the 1970s and 1980s, when it was used as a heuristic device, but lost importance in the early 1990s, when it was criticized by several empirical studies. A life-history paradigm has replaced the r/K selection paradigm but continues to incorporate many of its important themes.

🔗 The Boston Camera

🔗 Maps 🔗 Photography

The Boston Camera, also known as Pie Face and officially classified as the K-42 Camera Model, was a prototype airborne photo reconnaissance camera manufactured for the United States Air Force by Boston University in 1951 and tested on the Convair B-36 and the C-97 Stratofreighter. The model carried on the first ERB-36D (44-92088) had a 6,096-millimetre (240.0 in) focal length, which was achieved using a series of lenses and mirrors. The lens had an f/8 stop and used a 1/400 second shutter speed, and could photograph a golf ball from an altitude of 45,000 feet (14,000 m) feet. The camera used 18-by-36-inch (46 by 91 cm) negatives. The camera was installed aboard Boeing C-97A 49-2592 (not an "RC-97" or "EC-97" as often widely quoted) which was used operationally by the 7405th Support Squadron based at Wiesbaden, West Germany between 1952 and 1962. It was given to the Air Force Museum in 1964, along with a contact print of a golf ball on a course.

In the words of CIA historian Dino Brugioni:

The lens was designed in 1947 by Dr. James Baker for installation in a camera designed by the Boston University Optical Research Laboratory. The camera weighed about three tons, and eight hundred pounds of lead shot were required to balance it. Supposedly, it was first installed and test-flown in an RB-36, then installed as a left-looking oblique camera in an RC-97. The first photo Arthur Lundahl and I saw from this project was of New York City. The aircraft was seventy-two miles away, and yet we could see people in Central Park.

The Boston Camera was plagued with problems that caused it to vibrate and produce smearing on the newspaper-sized negative, so that photo interpreters would see several smeared frames along with several clear ones. It is currently displayed at the National Museum of the US Air Force in Dayton, Ohio.

From the display placard:

This camera, manufactured for the US Air Force by Boston University in 1951, is the largest aerial camera ever built. It was installed in an RB-36D in 1954 and tested for about a year. Later it was used in a C-97 aircraft flying along the air corridor through communist East Germany to Berlin, but a 10,000 ft (3,000 m) altitude restriction imposed by the communists made the camera less useful than at a higher altitude. It was also used on reconnaissance missions along the borders of Eastern European nations. The camera made an 18 x 36 inch negative and was so powerful a photo interpreter could detect a golf ball from an altitude of 45,000 feet (14,000 m). Dr. James Baker of Harvard University designed the camera.

Technical Notes:

Shutter Speed: 1/400 sec

Weight: 6,500 lbs (3 metric ton) (camera and aircraft mount)

🔗 Balloon Experiments with Amateur Radio

🔗 Aviation 🔗 Canada 🔗 Aviation/aircraft 🔗 Amateur radio 🔗 Canada/Alberta

Balloon Experiments with Amateur Radio (BEAR) is a series of Canadian-based amateur radio high-altitude balloon experiments by a group of amateur radio operators and experimenters from Sherwood Park and Edmonton, Alberta. The experiments started in the year 2000 and continued with BEAR-9 in 2012 reaching 36,010 metres (118,140 ft).

The balloons are made of latex filled with either helium or hydrogen. All of the BEAR payloads carry a tracking system comprising a GPS receiver, an APRS encoder, and a radio transmitter module. Other experimental payload modules include an Amateur Radio crossband repeater, and a digital camera all of which is contained within an insulated foam box suspended below the balloon. A parachute recovery system is automatically deployed when the balloon bursts at altitude.

🔗 Turnspit Dog

🔗 Dogs

The turnspit dog was a short-legged, long-bodied dog bred to run on a wheel, called a turnspit or dog wheel, to turn meat. It is mentioned in Of English Dogs in 1576 under the name "Turnespete". William Bingley's Memoirs of British Quadrupeds (1809) also talks of a dog employed to help chefs and cooks. It was also known as the Kitchen Dog, the Cooking Dog, or the Wheeling Dog. In Linnaeus's 18th-century classification of dogs it is listed as Canis vertigus (also used as Latin name for the Dachshund). The breed was lost, since it was considered to be such a lowly and common dog that no record was effectively kept of it. Some sources consider the turnspit dog a kind of Glen of Imaal Terrier, while others make it a relative of the Welsh Corgi.

With advancements in kitchen technology, the need for turnspit dogs declined. Over time, they were no longer bred for their specific function, and their numbers dwindled, eventually leading to their extinction.

A preserved example of a turnspit dog is displayed at Abergavenny Museum in Abergavenny, Wales.

Yakhchāl (Persian: یخچال‎ "ice pit"; yakh meaning "ice" and chāl meaning "pit") is an ancient type of evaporative cooler. Above ground, the structure had a domed shape, but had a subterranean storage space. It was often used to store ice, but sometimes was used to store food as well. The subterranean space coupled with the thick heat-resistant construction material insulated the storage space year round. These structures were mainly built and used in Persia. Many that were built hundreds of years ago remain standing.

🔗 Cippi of Melqart

🔗 History 🔗 Ancient Near East 🔗 Malta 🔗 Phoenicia

The Cippi of Melqart are a pair of Phoenician marble cippi that were unearthed in Malta under undocumented circumstances and dated to the 2nd century BC. These are votive offerings to the god Melqart, and are inscribed in two languages, Ancient Greek and Phoenician, and in the two corresponding scripts, the Greek and the Phoenician alphabet. They were discovered in the late 17th century, and the identification of their inscription in a letter dated 1694 made them the first Phoenician writing to be identified and published in modern times. Because they present essentially the same text (with some minor differences), the cippi provided the key to the modern understanding of the Phoenician language. In 1758, the French scholar Jean-Jacques Barthélémy relied on their inscription, which used 17 of the 22 letters of the Phoenician alphabet, to decipher the unknown language.

The tradition that the cippi were found in Marsaxlokk was only inferred by their dedication to Heracles, whose temple in Malta had long been identified with the remains at Tas-Silġ. The Grand Master of the Order of the Knights Hospitaller, Fra Emmanuel de Rohan-Polduc, presented one of the cippi to the Académie des Inscriptions et Belles-Lettres in 1782. This cippus is currently in the Louvre Museum in Paris, while the other rests in the National Museum of Archaeology in Valletta, Malta. The inscription is known as KAI 47.

🔗 Today Is International Day of Happiness

🔗 International relations 🔗 Philosophy 🔗 Psychology 🔗 Philosophy/Ethics 🔗 Holidays 🔗 International relations/United Nations

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,
