Paleo-inspiration
Paleo-inspiration is a paradigm shift that leads scientists and designers to draw inspiration from ancient materials (from art, archaeology, natural history or paleo-environments) to develop new systems or processes, particularly with a view to sustainability. Paleo-inspiration has already contributed to numerous applications in fields as varied as green chemistry, the development of new artist materials, composite materials, microelectronics, and construction materials. Semantics and definitions While this type of application has been known for a long time, the concept itself was coined by teams from the French National Centre for Scientific Research, the Massachusetts Institute of Technology and the Bern University of Applied Sciences from the term Bioinspiration. They published the concept in a seminal paper published online in 2017 by the journal Angewandte Chemie. Different names have been used to designate the corresponding systems, in particular: paleo-inspired, antiqu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bioinspiration
Bioinspiration is the development of novel materials, devices, and structures inspired by solutions found in biological evolution and refinement which has occurred over millions of years. The goal is to improve modeling and simulation of the biological system to attain a better understanding of nature's critical structural features, such as a wing, for use in future bioinspired designs. Bioinspiration differs from biomimicry in that the latter aims to precisely replicate the designs of biological materials. Bioinspired research is a return to the classical origins of science: it is a field based on observing the remarkable functions that characterize living organisms and trying to abstract and imitate those functions. History Ideas in science and technology often arise from studying nature. In the 16th and 17th century, Galileo Galilei, G. Galilei, Johannes Kepler, J. Kepler and Isaac Newton, I. Newton studied the motion of the sun and the planets and developed the first empirical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Anthropology
Anthropology is the scientific study of humanity, concerned with human behavior, human biology, cultures, societies, and linguistics, in both the present and past, including past human species. Social anthropology studies patterns of behavior, while cultural anthropology studies cultural meaning, including norms and values. A portmanteau term sociocultural anthropology is commonly used today. Linguistic anthropology studies how language influences social life. Biological or physical anthropology studies the biological development of humans. Archaeological anthropology, often termed as 'anthropology of the past', studies human activity through investigation of physical evidence. It is considered a branch of anthropology in North America and Asia, while in Europe archaeology is viewed as a discipline in its own right or grouped under other related disciplines, such as history and palaeontology. Etymology The abstract noun ''anthropology'' is first attested in reference t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reverse Engineering
Reverse engineering (also known as backwards engineering or back engineering) is a process or method through which one attempts to understand through deductive reasoning how a previously made device, process, system, or piece of software accomplishes a task with very little (if any) insight into exactly how it does so. It is essentially the process of opening up or dissecting a system to see how it works, in order to duplicate or enhance it. Depending on the system under consideration and the technologies employed, the knowledge gained during reverse engineering can help with repurposing obsolete objects, doing security analysis, or learning how something works. Although the process is specific to the object on which it is being performed, all reverse engineering processes consist of three basic steps: Information extraction, Modeling, and Review. Information extraction refers to the practice of gathering all relevant information for performing the operation. Modeling refers to th ...

Taphonomy
Taphonomy is the study of how organisms decay and become fossilized or preserved in the paleontological record. The term ''taphonomy'' (from Greek , 'burial' and , 'law') was introduced to paleontology in 1940 by Soviet scientist Ivan Efremov to describe the study of the transition of remains, parts, or products of organisms from the biosphere to the lithosphere. The term taphomorph is used to describe fossil structures that represent poorly-preserved, deteriorated remains of a mixture of taxonomic groups, rather than of a single one. Description Taphonomic phenomena are grouped into two phases: biostratinomy, events that occur between death of the organism and the burial; and diagenesis, events that occur after the burial. Since Efremov's definition, taphonomy has expanded to include the fossilization of organic and inorganic materials through both cultural and environmental influences. This is a multidisciplinary concept and is used in slightly different contexts throughout ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chaîne Opératoire
Chaîne opératoire (; ) is a term used throughout anthropological discourse, but is most commonly used in archaeology and sociocultural anthropology. It functions as a methodological tool for analysing the technical processes and social acts involved in the step-by-step production, use, and eventual disposal of artifacts, such as lithic reduction (the making of stone tools) or pottery. This concept of technology as the science of human activities was first proposed by French archaeologist, André Leroi-Gourhan, and later by the historian of science André-Georges Haudricourt. Both were students of Marcel Mauss who had earlier recognised that societies could be understood through its techniques by virtue of the fact that operational sequences are steps organised according to an internal logic specific to a society. The chaîne opératoire was born out of the need to explicitly describe the methodology of lithic analysis in archaeological scholarship. It allows archaeologists to ...

Observation
Observation is the active acquisition of information from a primary source. In living beings, observation employs the senses. In science, observation can also involve the perception and recording of data via the use of scientific instruments. The term may also refer to any data collected during the scientific activity. Observations can be qualitative, that is, only the absence or presence of a property is noted, or quantitative if a numerical value is attached to the observed phenomenon by counting or measuring. Science The scientific method requires observations of natural phenomena to formulate and test hypotheses. It consists of the following steps: # Ask a question about a natural phenomenon # Make observations of the phenomenon # Formulate a hypothesis that tentatively answers the question # Predict logical, observable consequences of the hypothesis that have not yet been investigated # Test the hypothesis' predictions by an experiment, observational study, field study, or ...

Soft Chemistry
Soft chemistry (also known as chimie douce) is a type of chemistry that uses reactions at ambient temperature in open reaction vessels with reactions similar to those occurring in biological systems. Aims The aim of the soft chemistry is to synthesize materials, drawing capacity of living beings - more or less basic - such as diatoms capable of producing glass from silicates dissolved. It is a new branch of materials science that differs from conventional solid-state chemistry and its application to the intense energy to explore the chemical inventiveness of the living world. This specialty emerged in the 1980s around the label of "chimie douce", which was first published by the French chemist, Jacques Livage in ''Le Monde'', 26 October 1977.J. Livage, "Vers une chimie écologique. Quand l’air et l’eau remplacent le pétrole", Le Monde (1977) October 26th French hits, the term ''soft chemistry'' is employed as such in the early twenty-first century in scientific publication ...

Sustainable Development
Sustainable development is an organizing principle for meeting human development goals while also sustaining the ability of natural systems to provide the natural resources and ecosystem services on which the economy and society depend. The desired result is a state of society where living conditions and resources are used to continue to meet human needs without undermining the integrity and stability of the natural system. Sustainable development was defined in the 1987 Brundtland Report as "Development that meets the needs of the present generation without compromising the ability of future generations to meet their own needs".United Nations General Assembly (1987''Report of the World Commission on Environment and Development: Our Common Future'' Transmitted to the General Assembly as an Annex to document A/42/427 – Development and International Co-operation: Environment. As the concept of sustainable development developed, it has shifted its focus more towards the economic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Optical Properties
The optical properties of a material define how it interacts with light. The optical properties of matter are studied in optical physics, a subfield of optics. The optical properties of matter include: *Refractive index *Dispersion *Transmittance and Transmission coefficient *Absorption *Scattering *Turbidity *Reflectance and Reflectivity (reflection coefficient) *Albedo *Perceived color *Fluorescence *Phosphorescence *Photoluminescence *Optical bistability * Dichroism *Birefringence *Optical activity *Photosensitivity A basic distinction is between isotropic materials, which exhibit the same properties regardless of the direction of the light, and anisotropic ones, which exhibit different properties when light passes through them in different directions. The optical properties of matter can lead to a variety of interesting optical phenomena. Properties of specific materials *Optical properties of water and ice *Optical properties of carbon nanotubes *Crystal optics See also *Rama ...

Magnetic Properties
Magnetism is the class of physical attributes that are mediated by a magnetic field, which refers to the capacity to induce attractive and repulsive phenomena in other entities. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. Magnetism is one aspect of the combined phenomena of electromagnetism. The most familiar effects occur in ferromagnetic materials, which are strongly attracted by magnetic fields and can be magnetization, magnetized to become permanent magnets, producing magnetic fields themselves. Demagnetizing a magnet is also possible. Only a few substances are ferromagnetic; the most common ones are iron, cobalt, and nickel and their alloys. The rare-earth metals neodymium and samarium are less common examples. The prefix ' refers to iron because permanent magnetism was first observed in lodestone, a form of natural iron ore called magnetite, Fe3O4. All substances exhibit ...
