The McDonnell Douglas High Speed Civil Transport (HSCT) was a proposed supersonic transport aircraft project initiated by McDonnell Douglas in the late 1980s and early 1990s. The aircraft was intended to provide faster-than-sound air travel for commercial passengers, potentially reducing transcontinental flight times significantly compared to conventional subsonic jets. The HSCT project aimed to achieve cruise speeds of around Mach 2.
Next Generation Supersonic Transport (NGST) refers to ongoing efforts and projects aimed at developing advanced supersonic passenger aircraft that can travel faster than the speed of sound (Mach 1), while also addressing many of the environmental, economic, and regulatory challenges that limited the success of earlier supersonic jets, such as the Concorde.
The LAPCAT A2 (Long-term Advanced Propulsion Concept for Air Transport) is a conceptual aerospace vehicle developed by Reaction Engines Limited. It is designed as a high-speed air transport system that seeks to combine the functionality of a subsonic airliner with the speed of a hypersonic vehicle. The LAPCAT A2 aims to achieve cruise speeds of around Mach 4, which is four times the speed of sound, enabling long-distance travel that could significantly reduce flight times.
The Sud Aviation Super-Caravelle is a French twin-engine jet airliner that was developed in the 1960s. It is an extended version of the earlier Sud Aviation Caravelle, which was one of the first jets designed specifically for short and medium-haul passenger flights. The Super-Caravelle featured improvements in range, capacity, and performance compared to its predecessor.
A supersonic business jet (SSBJ) is an advanced type of business aircraft designed to travel faster than the speed of sound, typically exceeding Mach 1 (approximately 1,235 kilometers per hour or 767 miles per hour at sea level). These jets aim to significantly reduce flight times on long-distance travel, allowing business travelers to spend less time in transit and more time at their destinations.
Sungazing, or sun gazing, is a practice that involves looking directly at the sun during specific times of the day, usually at sunrise or sunset, when the sun is less intense. Proponents of sungazing claim various benefits, such as increased energy, improved mental clarity, enhanced mood, and even potential healing effects. The practice is often associated with certain spiritual and philosophical traditions, and some practitioners believe it can help foster a deeper connection to nature and the universe.
"Communalness" typically refers to the quality or state of being communal, meaning it relates to the collective or shared aspects of a community. This concept often encompasses values such as cooperation, mutual support, social interaction, and shared resources among members of a group or society. In various contexts, communalness might include: 1. **Social Cohesion**: The strength of relationships and sense of belonging among members of a community.
Dense heterarchy refers to a complex organizational structure characterized by multiple layers of authority and interconnections among various components, rather than a simple top-down hierarchy or a purely flat structure. In a dense heterarchy, different units or teams can have overlapping roles, functions, and relationships, enabling them to collaborate and adapt more flexibly to changing conditions. This concept is often discussed in the context of organizational theory, systems theory, and social networks.
Eusociality is a term used in biology to describe a complex social structure typically seen in certain species of insects, such as bees, ants, wasps, and termites, as well as in a few other animal groups. Eusocial organisms exhibit three main characteristics: 1. **Cooperative brood care**: Members of the colony work together to care for the young, which often includes tasks such as feeding and protecting the offspring.
Francis Heylighen is a Belgian scientist known for his work in the fields of cybernetics, systems theory, and philosophical studies of complexity and self-organization. He is associated with the Vrije Universiteit Brussel and has contributed to research on topics such as the evolution of complex systems, the nature of intelligence, and the implications of technology on society.
The Gaia hypothesis, proposed by scientist James Lovelock in the 1970s, suggests that the Earth and its biological systems behave as a single, self-regulating entity. According to this hypothesis, living organisms interact with their inorganic surroundings in a way that maintains conditions suitable for life.
The term "Global Brain" can refer to several concepts, depending on the context in which it is used. Here are the most common interpretations: 1. **Collective Intelligence**: The Global Brain concept often describes the collective intelligence that emerges from the interactions and connections among individuals worldwide, facilitated by technology and the internet.
The Medea hypothesis is a concept in ecology and evolutionary biology that suggests a potential explanation for the persistence of certain species and the resistance to extinction. It is named after the figure from Greek mythology, Medea, who is known for her vengeful actions. The hypothesis posits that some populations can survive and thrive in the face of environmental challenges through a combination of mechanisms that include the spread of deleterious genetic traits.
"Metaman" can refer to various concepts or products depending on the context. It may denote ideas related to metaphysics, a specific character in comics or literature, or various technology-related terms such as virtual avatars or identities in the digital realm. One possible interpretation is that it relates to the evolving concepts of identity and presence in metaverse environments, where individuals interact through avatars or digital representations.
Metasystem transition is a concept that originates from systems theory and complexity science. It refers to a significant shift in the organization and functionality of a system, often leading to the emergence of higher-level structures or complexity. In essence, it describes how a system can evolve from a simpler state to one that has greater complexity or capability, typically characterized by new properties or behaviors that were not present in the original system.
Ivar Waller is a notable figure known for his contributions to the field of mathematics, particularly in the areas of functional analysis and operator theory. He is best recognized for Waller's theorem and his work on compact operators and integral equations. His research has had a significant impact on mathematical theory and applications.
The solar azimuth angle is a measure used in solar energy applications, architecture, and related fields to describe the position of the sun in the sky at any given time during the day. Specifically, it is defined as the angle between the north direction (usually measured from true north) and the line to the sun measured in degrees clockwise. Here’s a basic breakdown of the concept: - **Reference Direction**: The azimuth angle is typically measured from true north.
A list of supersonic aircraft includes various types of military and civilian aircraft that have the capability to exceed the speed of sound (approximately 343 meters per second or 1,125 feet per second at sea level). Here’s a list that highlights some notable supersonic aircraft: ### Military Supersonic Aircraft 1. **Bell X-1** - The first aircraft to break the sound barrier, flown by Chuck Yeager in 1947.
The Lockheed Martin X-59 QueSST (Quiet Supersonic Technology) is an experimental aircraft being developed by Lockheed Martin in collaboration with NASA. Its primary objective is to demonstrate technologies that could enable supersonic flight over land while significantly reducing the sonic boom associated with such flight.
In Queensland, Australia, survey marks are reference points used in land surveying to establish precise locations and define boundaries. These marks are critical for ensuring accurate measurements and are used by surveyors when conducting land surveys for various purposes, including property development, construction, and land division.
