The vocal fry register (also known as pulse register, laryngealization, pulse phonation, creaky voice, creak, croak, popcorning, glottal fry, glottal rattle, glottal scrape) is the lowest vocal register and is produced through a loose glottal closure that permits air to bubble through slowly with a popping or rattling sound of a very low frequency. During this phonation, the arytenoid cartilages in the larynx are drawn together, which causes the vocal folds to compress rather tightly and become relatively slack and compact. This process forms a large and irregularly vibrating mass within the vocal folds that produces the characteristic low popping or rattling sound when air passes through the glottal closure. The register (if well controlled) can extend far below the modal voice register, in some cases up to 8 octaves lower, such as in the case of Tim Storms who holds the world record for lowest frequency note ever produced by a human, a G₋₇, which is only 0.189 Hz, inaudible to the human ear.

Vocal fry is thought to have become more common among young female speakers of American English in the early 21st century, with the style of speaking being considered informal, nonaggressive and urban-oriented.

The Space Transportation System (STS), also known internally to NASA as the Integrated Program Plan (IPP), was a proposed system of reusable manned space vehicles envisioned in 1969 to support extended operations beyond the Apollo program. (NASA appropriated the name for its Space Shuttle Program, the only component of the proposal to survive Congressional funding approval). The purpose of the system was twofold: to reduce the cost of spaceflight by replacing the current method of launching capsules on expendable rockets with reusable spacecraft; and to support ambitious follow-on programs including permanent orbiting space stations around the Earth and Moon, and a human landing mission to Mars.

In February 1969, President Richard Nixon appointed a Space Task Group headed by Vice President Spiro Agnew to recommend human space projects beyond Apollo. The group responded in September with the outline of the STS, and three different program levels of effort culminating with a human Mars landing by 1983 at the earliest, and by the end of the twentieth century at the latest. The system's major components consisted of:

• A permanent space station module designed for 6 to 12 occupants, in a 270-nautical-mile (500 km) low Earth orbit, and as a permanent lunar orbit station. Modules could be combined in Earth orbit to create a 50 to 100 person permanent station.
• A chemically fueled Earth-to-station shuttle.
• A chemically fueled space tug to move crew and equipment between Earth orbits as high as geosynchronous orbit, which could be adapted as a lunar orbit-to-surface shuttle.
• A nuclear-powered ferry using the NERVA engine, to move crew, spacecraft and supplies between low Earth orbit and lunar orbit, geosynchronous orbit, or to other planets in the solar system.

The tug and ferry vehicles would be of a modular design, allowing them to be clustered and/or staged for large payloads or interplanetary missions. The system would be supported by permanent Earth and lunar orbital propellant depots. The Saturn V might still have been used as a heavy lift launch vehicle for the nuclear ferry and space station modules. A special "Mars Excursion Module" would be the only remaining vehicle necessary for a human Mars landing.

As Apollo accomplished its objective of landing the first men on the Moon, political support for further manned space activities began to wane, which was reflected in unwillingness of the Congress to provide funding for most of these extended activities. Based on this, Nixon rejected all parts of the program except the Space Shuttle, which inherited the STS name. As funded, the Shuttle was greatly scaled back from its planned degree of reusability, and deferred in time. The Shuttle first flew in 1981, and was retired in 2011.

A second part of the system, Space Station Freedom, was approved in the early 1980s and announced in 1984 by president Ronald Reagan. However, this also became politically unviable by 1993, and was replaced with the International Space Station (ISS), with substantial contribution by Russia. The ISS was completed in 2010.

" '—All You Zombies—' " is a science fiction short story by American writer Robert A. Heinlein. It was written in one day, July 11, 1958, and first published in the March 1959 issue of Fantasy and Science Fiction magazine after being rejected by Playboy.

The story involves a number of paradoxes caused by time travel. In 1980, it was nominated for the Balrog Award for short fiction.

"'—All You Zombies—'" further develops themes explored by the author in a previous work: "By His Bootstraps", published some 18 years earlier. Some of the same elements also appear later in The Cat Who Walks Through Walls (1985), including the Circle of Ouroboros and the Temporal Corps.

The unusual title of the story, which includes both the quotation marks and dashes shown above, is a quotation from a sentence near the end of the story; the quotation is taken from the middle of the sentence, hence the dashes indicating edited text before and after the title.

The Boirault machine (French: Appareil Boirault), was an early French experimental landship, designed in 1914 and built in early 1915. It has been considered as "another interesting ancestor of the tank", and described as a "rhomboid-shaped skeleton tank without armour, with single overhead track". Ultimately, the machine was deemed impractical and was nicknamed Diplodocus militaris. It preceded the design and development of the English Little Willie tank by six months.

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 Chandrasekhar limit () is the maximum mass of a stable white dwarf star. The currently accepted value of the Chandrasekhar limit is about 1.4 M_☉ (2.765×10³⁰ kg).

White dwarfs resist gravitational collapse primarily through electron degeneracy pressure (compare main sequence stars, which resist collapse through thermal pressure). The Chandrasekhar limit is the mass above which electron degeneracy pressure in the star's core is insufficient to balance the star's own gravitational self-attraction. Consequently, a white dwarf with a mass greater than the limit is subject to further gravitational collapse, evolving into a different type of stellar remnant, such as a neutron star or black hole. Those with masses up to the limit remain stable as white dwarfs.

The limit was named after Subrahmanyan Chandrasekhar, an Indian astrophysicist who improved upon the accuracy of the calculation in 1930, at the age of 20, in India by calculating the limit for a polytrope model of a star in hydrostatic equilibrium, and comparing his limit to the earlier limit found by E. C. Stoner for a uniform density star. Importantly, the existence of a limit, based on the conceptual breakthrough of combining relativity with Fermi degeneracy, was indeed first established in separate papers published by Wilhelm Anderson and E. C. Stoner in 1929. The limit was initially ignored by the community of scientists because such a limit would logically require the existence of black holes, which were considered a scientific impossibility at the time. The fact that the roles of Stoner and Anderson are often forgotten in the astronomy community has been noted.

A Fu-Go (ふ号[兵器], fugō [heiki], lit. "Code Fu [Weapon]"), or fire balloon (風船爆弾, fūsen bakudan, lit. "balloon bomb"), was a weapon launched by Japan during World War II. A hydrogen balloon with a load varying from a 33 lb (15 kg) antipersonnel bomb to one 26-pound (12 kg) incendiary bomb and four 11 lb (5.0 kg) incendiary devices attached, it was designed as a cheap weapon intended to make use of the jet stream over the Pacific Ocean and drop bombs on American cities, forests, and farmland. Canada and Mexico reported fire balloon sightings as well.

The Japanese fire balloon was the first ever weapon possessing intercontinental range (the second being the Convair B-36 Peacemaker and the third being the R-7 ICBM). The Japanese balloon attacks on North America were at that time the longest ranged attacks ever conducted in the history of warfare, a record which was not broken until the 1982 Operation Black Buck raids during the Falkland Islands War.

The balloons were intended to instill fear and terror in the U.S., though the bombs were relatively ineffective as weapons of destruction due to extreme weather conditions.

The European Green Belt initiative is a grassroots movement for nature conservation and sustainable development along the corridor of the former Iron Curtain. The term refers to both an environmental initiative as well as the area it concerns. The initiative is carried out under the patronage of the International Union for Conservation of Nature and Mikhail Gorbachev. It is the aim of the initiative to create the backbone of an ecological network that runs from the Barents to the Black and Adriatic Seas.

The European Green Belt as an area follows the route of the former Iron Curtain and connects National Parks, Nature Parks, Biosphere Reserves and transboundary protected areas as well as non-protected valuable habitats along or across the (former) borders.
