Lumpers and splitters are opposing factions in any discipline that has to place individual examples into rigorously defined categories.The lumper–splitter problem occurs when there is the desire to create classifications and assign examples to them, for example schools of literature, biological taxa and so on. A "lumper" is an individual who takes a gestalt view of a definition, and assigns ...

Atoms contain three types of subatomic particles called protons, neutrons, and electrons. Protons carry a positive charge and are found in the nucleus of an atom. The mass of a proton is 1.6726219 × 10-27 kilograms.

History. The special case of Fubini's theorem for continuous functions on a product of closed bounded subsets of real vector spaces was known to Leonhard Euler in the 18th century. Henri Lebesgue () extended this to bounded measurable functions on a product of intervals. Levi (1906)) conjectured that the theorem could be extended to functions that were integrable rather than …

Finite rearrangement. We have seen that by partitioning the disk into an infinite number of pieces we can reassemble the pieces into a rectangle. A remarkable fact discovered relatively recently (Laczkovich 1990) is that we can dissect the disk into a large but finite number of pieces and then reassemble the pieces into a square of equal area.

by definition and the binomial formula.Since, formally, ⁡ = and ⁡ =, we have shown that ⁡ (+) =.Since the limit of the Cauchy product of two absolutely convergent series is equal to the product of the limits of those series, we have proven the formula ⁡ (+) = ⁡ ⁡ for all ,.; As a second example, let = = for all .Then = + for all so the Cauchy product

Karl Marx's theory of alienation describes the estrangement (German: Entfremdung) of people from aspects of their human nature (Gattungswesen, 'species-essence') as a consequence of the division of labor and living in a society of stratified social classes.The alienation from the self is a consequence of being a mechanistic part of a social class, the condition of which estranges a …
