The quantum mind or quantum consciousness hypothesis proposes that classical mechanics cannot explain consciousness, while quantum mechanical phenomena, such as quantum entanglement and superposition, may play an important part in the brain's function, and could form the basis of an explanation of consciousness. It is not one theory, but a collection of distinct ideas described below. A few theoretical physicists have argued that classical physics is intrinsically incapable of explaining the holistic aspects of consciousness, whereas quantum mechanics can. The idea that quantum theory h...

In grammar, a particle is a function word which must be associated with another word or phrase to impart meaning, i.e. which does not have its own lexical definition. On this definition, particles are a separate part of speech and are distinct from other classes of function words, such as articles, prepositions, conjunctions and adverbs. Particles are typically words which encode grammatical categories (such as negation, mood, tense or case), clitics or fillers or (oral) discourse markers such as well, um, etc. Particles are never inflected. Languages vary widely in how much they use ...

Devil's food cake is a moist, airy, rich chocolate layer cake. It is considered a counterpart to the white or yellow angel food cake. Because of differing recipes and changing ingredient availability over the course of the twentieth century, it is difficult to precisely qualify what distinguishes Devil's food from the more standard chocolate cake, though it traditionally has more chocolate than a regular chocolate cake, making it darker. The cake is usually paired with a rich chocolate frosting. Overview Devil's food cake is generally more moist and airy than other chocolate cakes, and o...
