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.

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.

Sites that contain information and theory of pyrotechnics, ballistics, and explosives.

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.

Chemistry is typically defined as the science that studies the composition, structure, and transformation of matter. It has been called "the central science" because of the way it is related with all the other sciences. Chemistry bridges the gap between physics and biology; it is a "helper science" in almost many technical disciplines; and it occupies a prominent position in industry between the extraction of raw materials and the manufacture of finished products. Of course, it is chemists who call it this way; other scientists may have different perspectives. Chemistry is also distinguished from some other sciences because it creates its own object of study: chemists can imagine and create new compounds that have never existed in nature, so they are not constrained to what already exists, but only to what can be done.

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.

Meteorology is the branch of science which studies weather. It is often an inexact science, especially when forecasting is involved, so that predictions often are stated as a percentage of probability. Listings here should concern the scientific practice of meteorology, information about weather events of historical interest, meteology as a hobby, and some instruments and products which either facilitate scientific meteorology or come from that background. Listings related to finding or reporting weather news should go to News: Weather.

Physics of light.

"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.

Biology = Life Sciences Some of the major fields in the life sciences include botany, zoology, microbiology, biochemistry, genetics, ecology. Some areas of biology are closely aligned to medicine, agriculture, and biotechnology. Related: Where should I submit my website about animals?
