Topic search for environment - Topodia makes research easy.

robots , robot , robotics , university , humanoids

Robotics is a term coined by Isaac Asimov to describe the field of science involving robots and related technologies. So what is a robot? The word comes from a 1923 Czech play called R.U.R. and described autonomous, humanoid robot servants. The original Czech word was robota, which means "servitude or forced labor". According to the Syrius Cybernetics Corporation of Douglas Adams' Hitchiker's Guide to the Galaxy, a robot is "your plastic pal who's fun to be with". A more conventional definition is, "A mechanical device that sometimes resembles a human and is capable of performing a variety of often complex human tasks". There are many other definitions, some a bit too narrow and some far too broad. We try to be as inclusive as possible, accepting sites about hobby robotics, industrial robotics, even those about the radio-controlled entertainment vehicles of "Robot Wars". Enjoy our selections. And if you don't agree with some of our choices, rest easy in the knowledge that someone else out there wouldn't agree with yours.

Ecology

strong advocate , biodiversity , wilderness , biological diversity , brad shaw

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.

Energy

system , potential energy , kinetic energy , energy , energy star

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.

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.

Nanotechnology

Nanotechnology: a general term covering nanoscale science and engineering. A more narrow definition is miniaturization engineering at the nanometer scale. Nano is a metric prefix meaning 'billionth', in this case, science, technology, and engineering at sizes measured in billionths of a meter, which is 1,000 times smaller than a micrometer. It is proposed to build electronic and mechanical devices which are made of very tiny parts (as are biotic systems), but which may have very large effects (as do biotic systems).

Some of these elements will remain radioactive for a few years, while others will be radioactive for millions of years.
Nuclear waste can be generally classified as either low level or high level radioactive waste. Low level nuclear waste usually includes material used to handle the radioactive parts of nuclear apparatus and waste from nuclear medicine. High level waste includes the fission products activated in nuclear reactors or in accelerators.

This category contains non-commercial scientific, educational, and governmental references to biomass and biofuel. Biomass is organic non-fossil material. It comprises the mass of all biological organisms, dead or alive, excluding biological mass that has been transformed by geological processes into substances such as coal or petroleum. Solid biomass comes in different forms including what comes directly from the “producers” (grass, trees, shrubs, crop husks, etc.) and that which comes as waste from the animals that consume the producers (droppings or dung from animals and waste from humans). Biofuel is any fuel that originates from biomass. The three classes of biomass used for combustion are solid (e.g. wood, dried plants and animal waste), liquid (e.g. ethanol, methanol and vegetable oil) and gaseous (e.g. bio-methane and hydrogen).

Biodiversity

species , biodiversity , biological diversity , variety , ecosystems

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.

Permaculture

permaculture , system , permaculture design , systems , natural systems

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.
