Alkaline Meaning The origin of the word alkaline is Arabic. It comes from “alqali” and can be translated as “ash”, a base substance that was achieved by the combustion of wood. By alkaline we mean, in a substance, the description of its pH balance (power of hydrogen). A base or alkali is a notion that is opposed to that of acid since alkaline substances have high pH levels. While acids have excess hydrogen ions, a spicy and acrid taste, they are corrosive when in contact with the skin, their solutions are electrolytes and litmus paper turns red in their presence;…
Stroke Meaning The word apoplexy derives from the Greek language, from “apolixia” with the meaning of loss of sense or attack that produces immobility, or from “apóplexin”, with the meaning of sudden or sudden, the term already used by Hippocrates, father of medicine (460 to 370 BC). From there it went into Latin as “apoplexia” which means paralysis. Saint Isidore of Seville, in his book “Etymologies”, from the middle of the 7th century, tells us that apoplexy, with the meaning of a fatal blow, is a blood effusion, which suddenly causes the death of the person by suffocation, falling suddenly.…
Aberration Meaning Aberration is a word etymologically from the Latin “aberratio”, whose meaning is something that wanders errantly or has deviated from the correct path. The word aberration is used in Astronomy to designate the change in location that a star appears to have caused by the Earth’s translational movement and the propagation movement of light. In Optics it refers to the lack of correspondence between the image of an object or subject, reproduced by an optical system. In Biology, aberrant reference is made to everything that deviates from what is considered normal. For example, aberrations or also called chromosomal…
Alkaloid Meaning The term alkaloid was coined as “alkaloid” in 1818 by the German pharmacist Karl Friedrich Wilhelm Meissner, uniting the terms “alkalis” which refers to alkaline carbonates and “–oid” which alludes to a similarity. In general, alkaloids come from plants, being secondary metabolites of them, synthesized. Protoalkaloids are those of animal origin. They are water-soluble at acidic pH and soluble in organic solvents at alkaline pH. Those that are considered true are derived from an amino acid, and are nitrogenous, generally having great physiological action on animal organisms and man, being psychoactive. Among the best-known alkaloids, we can name…
Aporia Meaning The word aporia (or aporima) has its origin in the Greek language. It comes from ἀπορία, the word integrated by the prefix: α (a) which translates as “without”, referring to a denial or absence; and by πόρος (póros) which means “exit” or “passage”. Literally, an aporia is that which has no way out, because in itself, it contains a contradiction. Synonyms of aporia: Dichotomy, contradiction, paradox, and insurmountable difficulty. Aporias are made up of contradictory propositions, which appear irrational or meaningless, and leave no possibility of finding a solution that provides light to the dilemma, yielding conclusions that…
