| Artificial intelligence Artificial Intelligence (AI) is the intelligence of machines and the branch of computer science which aims to create it. Major AI textbooks define the field as "the study and design of intelligent agents," John McCarthy, who coined the term in 1956,The field was founded on the claim that a central property of human beings, intelligence—the sapience of Homo sapiens—can be so precisely described that it can be simulated by a machine.

| Attribution of recent climate change Attribution of recent climate change is the effort to scientifically ascertain mechanisms responsible for relatively recent changes observed in the Earth's climate. The effort has focused on changes observed during the period of instrumental temperature record, when records are most reliable; particularly on the last 50 years, when human activity has grown fastest and observations of the upper atmosphere have become available.

| Bose–Einstein condensate Bose–Einstein condensate (BEC) is a state of matter of a dilute gas of weakly interacting bosons confined in an external potential and cooled to temperatures very near to absolute zero (, , or ). Under such conditions, a large fraction of the bosons collapse into the lowest quantum state of the external potential, and all wave functions overlap each other, at which point quantum effects become apparent on a macroscopic scale.

| Consciousness Consciousness is often used colloquially to describe being awake and aware—responsive to the environment, in contrast to being asleep or in a coma. In philosophical and scientific discussion, however, the term is restricted to the specific way in which humans are mentally aware in such a way that they distinguish clearly between themselves (the thing being aware) and all other things and events. This "self-awareness" may involve thoughts, sensations, perceptions, moods, emotions, and dreams. Consciousness

| Carbon monoxide Carbon monoxide, with the chemical formula CO, is a colorless, odorless and tasteless, yet highly toxic gas. Its molecules consist of one carbon atom and one oxygen atom, connected by a covalent double bond and a dative covalent bond. It is the simplest oxocarbon, and can be viewed as the anhydride of formic acid (CH2O2).Carbon monoxide is produced from the partial oxidation of carbon-containing compounds; it forms in preference to the more usual carbon dioxide (CO2) when there is a reduced availability of oxygen, such as when operating a stove or an internal combustion engine in an enclosed space.

| Cantigas de Santa Maria Cantigas de Santa Maria ("Songs to the Virgin Mary") are manuscripts written in Galician-Portuguese, with music notation, during the reign of Alfonso X El Sabio (1221-1284) and are one of the largest collections of monophonic (solo) songs from the Middle Ages. All of the songs at least mention the Virgin Mary, and every 10th is a religious hymn.

| Chaos theory mathematics, chaos theory describes the behavior of certain dynamical systems – that is, systems whose states evolve with time – that may exhibit dynamics that are highly sensitive to initial conditions (popularly referred to as the butterfly effect). As a result of this sensitivity, which manifests itself as an exponential growth of perturbations in the initial conditions, the behavior of chaotic systems appears to be random. Chaos_theory

It is separate and distinct from reading difficulties resulting from other causes, such as a non-neurological deficiency with vision or hearing, or from poor or inadequate reading instruction, This suggests that dyslexia results from differences in how the brain processes written and spoken language.

| Dodo The dodo (Raphus cucullatus) was a flightless bird endemic to the Indian Ocean island of Mauritius. Related to pigeons and doves, it stood about a meter tall, weighing about , living on fruit and nesting on the ground.The dodo has been extinct since the mid-to-late 17th century. It is commonly used as the archetype of an extinct species because its extinction occurred during recorded human history, and was directly attributable to human activity. Dodo
