Topics from Topodia matching the term "nature"
Artificial Intelligence is a field of science that has several goals. The first, often called "weak" AI, is the effort to design and implement computer systems that can perform tasks requiring intelligence when performed by humans. AI in computer games, knowledge based systems and such are typical examples of this branch. The second, less tangible branch, often called "strong" AI, is the research that ultimatly aims to build artificial systems that display real intelligence. It does this by trying to understand or model the nature of human intelligence. Both branches are multidisciplinary, in that they have close relations with the fields of computer science, philosophy, medicine, psychology, biology and linguistics.
This category deals with all things pertaining to the technology, theory, and science of aeronautics. Here you will find sites that describe the technical aspects of flying, aviation and aeronautics.

Ecology is a branch of science dealing with the interrelationships of organisms with one another and with their nonliving environment.

These relationships include physiological responses of individuals, structure and dynamics of populations, interactions among species, organization of biological communities, and processing of energy and matter in ecosystems.

Cognitive science topics which may span one or more specific sciences including psychology and medicine. Sites, works and indices that assume a scientific model in their processes, references or information gathering and summary.
In general, the concept of energy refers to the potential for causing changes. In physics, energy is the ability to do work and has many different forms (potential, kinetic, electromagnetic, etc.) No matter what its form, physical energy has the same units as work; a force applied through a distance. The SI unit of energy, the joule, equals one newton applied through one meter.
Topics for this category include energy resources, energy utilization technologies, technology research and technical innovations, and analytical aspects of energy policy.
A collection of scientific resources about the motion of fluids like liquids and gases.

"Physics is the study and application of the fundamental laws of nature, including the laws of motion, gravity, electromagnetism, heat, and microscopic interactions. These laws govern the behavior of objects at all scales, from the smallest subatomic particles to the entire observable universe. In between, physicists study nuclear reactions, the interactions of atoms with light, properties of solids, chaotic dynamics of fluids, and the evolution of stars and galaxies, among many other applications."

If this doesn't tickle your fancy, there is always the quote from Rutherford: "In science, there is only physics; all the rest is stamp collecting."

Critical evaluation of alternative science, paranormal phenomena, news reports about science, etc.
Sociology encompasses and overlaps many fields involves in the study of social relationships and institutions, including organizational behavior, societal development and structure, and cross-cultural interaction. The term "sociology" as the scientific analysis of collective human behavior was coined in 1838 by Auguste Comte, but Max Weber and ?mile Durkheim are generally credited as the founders of the modern field. The listings in this category are self-consciously restricted to links offering academic content or information. This also means that commercial sites that don't provide academic content (e.g., book sellers as compared to academic journal sites maintained by publishers) will not be listed.
Science is constantly reshaping itself through unexpected observations, new ideas, and revisions to old theories. While terms like "anomalies" or "alternative" may seem pejorative from an orthodox perspective, from an historical view these are the topics are the very life-blood of science. We must have heretics and revolutionaries challenging our beliefs, and advancing the state of the believable, otherwise science will stagnate into dogma.
Cryptozoology is the study of hidden animals not formally recognized by science, but supported in some way by other forms of evidence such as eyewitness accounts or tracks. Examples include Bigfoot and lake monsters(such as the Loch Ness Monster).

...Informatics is an emerging discipline that has been defined as the study, invention, and implementation of structures and algorithms to improve communication, understanding and management of medical information. The end objective of biomedical informatics is the coalescing of data, knowledge, and the tools necessary to apply that data and knowledge in the decision-making process, at the time and place that a decision needs to be made. The focus on the structures and algorithms necessary to manipulate the information separates Biomedical Informatics from other medical disciplines where information content is the focus." Aamir M. Zakaria., MD "Medical Informatics Frequently Asked Questions"

Biodiversity is not easily defined. Try What is Biodiversity? and Defining The 'B' Word for approaches with differing emphases. Below is a definition adapted from the World Resources Institute, World Conservation Union, and United Nations Environment Programme in Global Biodiversity Strategy 1992.

"Biodiversity is the totality of genes, species, and ecosystems in a region... Biodiversity can be divided into three hierarchical categories -- genes, species, and ecosystems -- that describe quite different aspects of living systems and that scientists measure in different ways.

Genetic diversity refers to the variation of genes within species. This covers distinct populations of the same species (such as the thousands of traditional rice varieties in India) or genetic variation within a populations (high among Indian rhinos, and very low among cheetahs) ...

Species diversity refers to the variety of species within a region. Such diversity can be measured in many ways, and scientists have not settled on a single best method. The number of species in a region -- its species richness -- is one often- used measure, but a more precise measurement, taxonomic diversity, also considers the relationship of species to each other. For example, an island with two species of birds and one species of lizard has a greater taxonomic diversity than an island with three species of birds but no lizards ...

Ecosystem diversity is harder to measure than species or genetic diversity because the boundaries of communities -- associations of species -- and ecosystems are elusive. Nevertheless, as long as a consistent set of criteria is used to define communities and ecosystems, their numbers and distribution can be measured ..."

Resources related to biodiversity or conservation as an issue or a topic of debate belong primarily in the relevant subcategory of Society/Issues/Environment.

A fractal is a chaotic mathematic object which can be divided into parts, each of which is similar to the original object. Fractals are said to possess infinite detail, and are generally self-similar and independent of scale. In many cases a fractal can be generated by a repeating pattern, typically a recursive or iterative process. The term fractal was coined in 1975 by Benoît Mandelbrot, from the Latin fractus or "broken"/"fraction". Chaos theory, in mathematics and physics, deals with the behavior of certain nonlinear dynamical systems that (under certain conditions) exhibit the phenomenon known as chaos, most famously characterised by sensitivity to initial conditions. Systems that exhibit mathematical chaos are deterministic and thus orderly in some sense; this technical use of the word chaos is at odds with common parlance, which suggests complete disorder.

It is supposed to provide resources for philosophy teachers, mostly at the college and university level, including sites on pedagogy in philosophy teaching, the teaching of particular subject areas, syllabi, handouts, etc. Philosophy sites which are of use mostly for students of philosophy, including online courses and course websites with substantial philosophical content should go in the most appropriate subcategory of Society/Philosophy.

Particle physics, often called High Energy Physics (HEP) deals with the smallest building blocks of everything around us - subatomic elementary particles.

It is not about particles you could see under a microscope (e.g. dust particles) and it is not about chemical molecules.

The World Wide Web was invented by particle physicists at CERN.

Classical mechanics generalized (extended) to realm of high velocities (special relativity), and strong gravitational fields (general relativity). In particular, the theory that time and space form a single 'spacetime' which is curved in the presence of energy and mass.
This category is intended for websites about the biology of specific organisms or taxonomic groups. The structure is organized according to a taxonomy tree, with the top-level subcategories being the five Kingdoms plus Viruses. Potential contents include descriptions and images of the organisms, classification, anatomy, physiology, behavior, distribution, reproduction and life cycle, habitat, biological or ecological aspects of management, endangered-species status, etc. Note: In establishing the taxonomy-based category structure, some subtaxons and taxon levels are intentionally omitted for: 1) escaping from "unstable" taxons; 2) ease in navigation; 3) convenience in editing.
The kingdom Fungi comprises not only the more familiar mushrooms and toadstools but also lichens, moulds, rusts, smuts and rot. In fact what we see are the fruiting bodies of the fungi,these being supported by a network of root-like strands called hyphae beneath the surface. Most fungi are saprobes, breaking down organic material and especially wood. Some are parasites and may be significant agents of plant or animal disease and some form a mutually beneficial relationship with the roots of plants. The phylum Basidiomycota includes the common mushrooms and toadstools, puffballs and bracket fungi and the phylum Ascomycota includes truffles, morels and other fungi with cup-shaped, club-shaped or various strangely-shaped fruiting bodies. There is great diversity in shape of these and their appearance may not be a good guide to their classification. The other main phyla are the Zygomycota or pin-moulds and the Chytridiomycota whose members are mostly aquatic, some being parasites. Modern genetic analysis is showing unexpected relationships between disparate groups and demonstrating that what had been thought to be closely related groups are actually far apart. The Fungi are now thought to be more closely related to the animal kingdom than the plant kingdom. Subcategories are organized according to the taxon tree: - Divisions -- Families --- Genera
Mycology = the study of Fungi The total kingdom of Fungi - from single cell yeasts through to large ''mushrooms''. Cultivation, finding, photographs, commercial growing, etc - the lot!
This category is for listing sites dealing with the genetics of the human race.

It is about the playing of harmony among things created.
In this category you can find everything on the possibilities of time travel (illusion or reality?) in the framework of Einstein's theory of relativity.
Permaculture is an integrated design system for sustainability. The word "permaculture" is a contraction of "permanent agriculture" or "permanent culture." Its roots are in the design of productive ecosystems for farms and gardens. A central theme in permaculture is the design of ecological landscapes that produce food. Emphasis is placed on multi-use plants, cultural practices such as sheet mulching and trellising, and the integration of animals to recycle nutrients and graze weeds. Permaculture concepts also reach beyond farming and gardens that into designs for all types of resilient, sustainable structures, both physical and social. It is a philosophy of maximum effort at the design stage to allow minimum effort and side-effects once the system is running, instead of the conventional method which is often the reverse.
Energy healing incorporates many modalities, from traditional ethnic practices to modern techniques developed from bioenergetic research. Since the living human body projects an energy field (aura) around it, it is possible to affect the solid corporeal body by working with its energetic projection.
Ayurveda is a holistic system of healing which evolved among the Brahmin sages of ancient India some 3000-5000 years ago. Ayurveda is a complete medical system which recognizes that ultimately all intelligence and wisdom flows from one Absolute source (Paramatman). Health manifests by the grace of the Absolute acting through the laws of Nature (Prakriti). Ayurveda assists Nature by promoting harmony between the individual and Nature by living a life of balance according to her laws.

History, Proof, and Conjectures related to Fermat's Last Theorem
Encyclopedia Britannica's says that "the chief concern of information theory is to discover mathematical laws governing systems designed to communicate or manipulate information. It sets up quantitative measures of information and of the capacity of various systems to transmit, store, and otherwise process information. Some of the problems treated are related to finding the best methods of using various available communication systems and the best methods for separating the wanted information, or signal, from the extraneous information, or noise". The study of information theory is also concerned with the definition of notion of information in a general sense and with a unified information theory that is supposed to contain all the statements of existing information theories.

According to Aristotle, rhetoric is "the faculty of observing in a given case the available means of persuasion." In contemporary terms, "rhetoric" is the social science that focuses on how to use language to create understanding and to change attitudes or behaviors. The earliest known works on rhetoric predate Aristotle, and rhetoric was an important part of a young Greek male's education to be a civic leader. Aristotle's theories were widely adopted and refined by rhetoricians of the Roman Empire, and later by Christian scholars. For over 1,000 years -- from about 600 A.D. to about 1800 -- rhetoric was one of the three liberal arts studied by every educated person. (The others were grammar and dialectic.) Around 1900, "rhetoric" became primarily the study of how to write effectively, while "speech" dominated college curricula as the study of effective persuasion. Today, these divisions are much less clear, but "rhetoric" is often distinguished from "communication studies" by a greater emphasis on criticism and practice, versus empirical or laboratory studies. In current usage, "rhetoric" has four connotations: 1. "Empty rhetoric." The popular use of the term to mean using words to confuse, bully, or obscure the issue. 2. Writing skills. Many departments of rhetoric focus on writing, especially technical writing. 3. Rhetorical theory. There is also a body of theory on how rhetoric works, some of it overlapping with literary theory. 4. Rhetorical criticism. The application of rhetorical theory in order to understand why a speech (or ad, or song, or whatever) was or was not persuasive.

Botanical Gardens and Arboreta are scientific institutions that acquire and maintain living collections of plants for the purposes of research and education. They perform the same function for plants as Zoos and Aquariums do for animals.

Typically, to belong within category Science:Institutions botanical gardens and arboreta must have a full-time scientific staff, an herbarium and library, and a catalogued collection of thousands of plants. Although botanical gardens and arboreta may also have a public viewing area, in which case they may be listed as well under Public Gardens, it is the presence of a viable research faculty using an herbarium or herbaria which distinguishes botanical gardens and arboreta from public gardens. This tends to make botanical gardens and arboreta larger in size and more dedicated to preservation of plant taxa than Public Gardens, however size or reputation are not the determining factors. Universities with herbaria do not constitute botanical gardens, even if there is a botanical garden on campus, and even if there is a research program involved, but are listed instead under Science: Biology: Botany: Education. The reason is that University botanical research falls within a traditional academic structure dedicated primarily to teaching.
