Our Final Hour
''Our Final Hour'' is a 2003 book by the British Astronomer Royal Sir Martin Rees. The full title of the book is ''Our Final Hour: A Scientist's Warning: How Terror, Error, and Environmental Disaster Threaten Humankind's Future In This Century—On Earth and Beyond''. It was published in the United Kingdom under the title ''Our Final Century: Will the Human Race Survive the Twenty-first Century?''. The premise of the book is that the Earth and human survival are in far greater danger from the potential effects of modern technology than is commonly realised, and that the 21st century may be a critical moment in history when humanity's fate is decided. Rees discusses a range of existential risks confronting humanity, and estimates that the probability of extinction before 2100 CE is around 50 percent, based on the possibility of malign or accidental release of destructive technology. Humanity's fate and recommendations for survival In ''Our Final Hour'', Rees predicts that one of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aum Shinrikyo
, formerly , is a Japanese doomsday cult founded by Shoko Asahara in 1987. It carried out the deadly Tokyo subway sarin attack in 1995 and was found to have been responsible for the Matsumoto sarin attack the previous year. The group says that those who carried out attacks did so secretly, without being known to other executives and ordinary believers. Asahara insisted on his innocence in a radio broadcast relayed from Russia and directed toward Japan. On 6 July 2018, after exhausting all appeals, Asahara and six followers were executed as a punishment for the 1995 attacks and other crimes, and the remaining six on death row were executed on 26 July. At 12:10 am, on New Year's Day 2019, at least nine people were injured (one seriously) when a car was deliberately driven into crowds celebrating the new year on Takeshita Street in Tokyo. Local police reported the arrest of Kazuhiro Kusakabe, the suspected driver, who allegedly admitted to intentionally ramming his vehicle into ...

Probability Theory
Probability theory is the branch of mathematics concerned with probability. Although there are several different probability interpretations, probability theory treats the concept in a rigorous mathematical manner by expressing it through a set of axioms. Typically these axioms formalise probability in terms of a probability space, which assigns a measure taking values between 0 and 1, termed the probability measure, to a set of outcomes called the sample space. Any specified subset of the sample space is called an event. Central subjects in probability theory include discrete and continuous random variables, probability distributions, and stochastic processes (which provide mathematical abstractions of non-deterministic or uncertain processes or measured quantities that may either be single occurrences or evolve over time in a random fashion). Although it is not possible to perfectly predict random events, much can be said about their behavior. Two major results in probability ...

Wealthy
Wealth is the abundance of valuable financial assets or physical possessions which can be converted into a form that can be used for transactions. This includes the core meaning as held in the originating Old English word , which is from an Indo-European word stem. The modern concept of wealth is of significance in all areas of economics, and clearly so for growth economics and development economics, yet the meaning of wealth is context-dependent. An individual possessing a substantial net worth is known as ''wealthy''. Net worth is defined as the current value of one's assets less liabilities (excluding the principal in trust accounts). At the most general level, economists may define wealth as "the total of anything of value" that captures both the subjective nature of the idea and the idea that it is not a fixed or static concept. Various definitions and concepts of wealth have been asserted by various individuals and in different contexts.Denis "Authentic Development: Is i ...

Space Colonization
Space colonization (also called space settlement or extraterrestrial colonization) is the use of outer space or celestial bodies other than Earth for permanent habitation or as extraterrestrial territory. The inhabitation and territorial use of extraterrestrial space has been proposed to be realized by for example building space settlements or extraterrestrial mining enterprises. To date, no permanent space settlement other than temporary space habitats have been set up, nor any extraterrestrial territory or land has been legally claimed. Making territorial claims in space is prohibited by international space law, defining space as a common heritage. International space law has had the goal to prevent colonial claims and militarization of space, advocating the installation of international regimes to regulate access to and sharing of space, particularly for specific locations such as the limited space of geostationary orbit or the Moon. Many arguments both for and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Free Market
In economics, a free market is an economic system in which the prices of goods and services are determined by supply and demand expressed by sellers and buyers. Such markets, as modeled, operate without the intervention of government or any other external authority. Proponents of the free market as a normative ideal contrast it with a regulated market, in which a government intervenes in supply and demand by means of various methods such as taxes or regulations. In an idealized free market economy, prices for goods and services are set solely by the bids and offers of the participants. Scholars contrast the concept of a free market with the concept of a coordinated market in fields of study such as political economy, new institutional economics, economic sociology and political science. All of these fields emphasize the importance in currently existing market systems of rule-making institutions external to the simple forces of supply and demand which create space for those ...

Long Bet Project
The Long Now Foundation, established in 1996, is an American non-profit organization based in San Francisco that seeks to start and promote a long-term cultural institution. It aims to provide a counterpoint to what it views as today's "faster/cheaper" mindset and to promote "slower/better" thinking. The Long Now Foundation hopes to "creatively foster responsibility" in the framework of the next 10,000 years. In a manner somewhat similar to the Holocene calendar, the foundation uses 5-digit dates to address the Year 10,000 problem (e.g., by writing the current year "0" rather than ""). The organisation's logo is , a capital X with an overline, a representation of 10,000 in Roman numerals. Projects The foundation has several ongoing projects, including a 10,000-year clock known as the ''Clock of the Long Now'', the ''Rosetta Project'', the ''Long Bet Project'', the open source ''Timeline Tool'' (also known as Longviewer), the ''Long Server'' and a monthly seminar series.

Bioterrorism
Bioterrorism is terrorism involving the intentional release or dissemination of biological agents. These agents are bacteria, viruses, insects, fungi, and/or toxins, and may be in a naturally occurring or a human-modified form, in much the same way as in biological warfare. Further, modern agribusiness is vulnerable to anti-agricultural attacks by terrorists, and such attacks can seriously damage economy as well as consumer confidence. The latter destructive activity is called agrobioterrorism and is a subtype of agro-terrorism. Definition Bioterrorism is the deliberate release of viruses, bacteria, toxins or other harmful agents to cause illness or death in people, animals, or plants. These agents are typically found in nature, but could be mutated or altered to increase their ability to cause disease, make them resistant to current medicines, or to increase their ability to be spread into the environment. Biological agents can be spread through the air, water, or in food. Bi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World Government
World government is the concept of a single political authority with jurisdiction over all humanity. It is conceived in a variety of forms, from tyrannical to democratic, which reflects its wide array of proponents and detractors. A world government with executive, legislative, and judicial functions and an administrative apparatus has never existed. The inception of the United Nations (UN) in the mid-20th century remains the closest approximation to a world government, as it is by far the largest and most powerful international institution. However, the UN is mostly limited to an advisory role, with the stated purpose of fostering cooperation between existing national governments, rather than exerting authority over them. Nevertheless, the organization is commonly viewed as either a model for, or preliminary step towards, a global government. The concept of universal governance has existed since antiquity and been the subject of discussion, debate, and even advocacy by some ...

Arms Control
Arms control is a term for international restrictions upon the development, production, stockpiling, proliferation and usage of small arms, conventional weapons, and weapons of mass destruction. Arms control is typically exercised through the use of diplomacy which seeks to impose such limitations upon consenting participants through international treaties and agreements, although it may also comprise efforts by a nation or group of nations to enforce limitations upon a non-consenting country. Enactment Arms control treaties and agreements are often seen as a way to avoid costly arms races which could prove counter-productive to national aims and future peace. Some are used as ways to stop the spread of certain military technologies (such as nuclear weaponry or missile technology) in return for assurances to potential developers that they will not be victims of those technologies. Additionally, some arms control agreements are entered to limit the damage done by warfare, es ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Warfare
Nuclear warfare, also known as atomic warfare, is a theoretical military conflict or prepared political strategy that deploys nuclear weaponry. Nuclear weapons are weapons of mass destruction; in contrast to conventional warfare, nuclear warfare can produce destruction in a much shorter time and can have a long-lasting radiological result. A major nuclear exchange would likely have long-term effects, primarily from the fallout released, and could also lead to secondary effects, such as " nuclear winter", nuclear famine and societal collapse. A global thermonuclear war with Cold War-era stockpiles, or even with the current smaller stockpiles, may lead to various scenarios including the extinction of the human race. To date, the only use of nuclear weapons in armed conflict occurred in 1945 with the American atomic bombings of Hiroshima and Nagasaki. On August 6, 1945, a uranium gun-type device (code name "Little Boy") was detonated over the Japanese city of Hiroshi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disarmament
Disarmament is the act of reducing, limiting, or abolishing weapons. Disarmament generally refers to a country's military or specific type of weaponry. Disarmament is often taken to mean total elimination of weapons of mass destruction, such as nuclear arms. General and Complete Disarmament was defined by the United Nations General Assembly as the elimination of all WMD, coupled with the “balanced reduction of armed forces and conventional armaments, based on the principle of undiminished security of the parties with a view to promoting or enhancing stability at a lower military level, taking into account the need of all States to protect their security.”UN General AssemblyFinal Document of the First Special Session on Disarmament, para. 22. History At the Hague Peace Conferences in 1899 and 1907 government delegations debated about disarmament and the creation of an international court with binding powers. The court was considered necessary because it was understood that nati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
