It was independently discovered in 1900 by the Japanese chemist Jōkichi Takamine and his assistant Keizo Uenaka. [49] [50] 1896: Two proofs of the prime number theorem (the asymptotic law of the distribution of prime numbers) were obtained independently by Jacques Hadamard and Charles de la Vallée-Poussin and appeared the same year.
Multiple discoveries in the history of science provide evidence for evolutionary models of science and technology, such as memetics (the study of self-replicating units of culture), evolutionary epistemology (which applies the concepts of biological evolution to study of the growth of human knowledge), and cultural selection theory (which studies sociological and cultural evolution in a ...
In mathematics, a function is a rule for taking an input (in the simplest case, a number or set of numbers) [5] and providing an output (which may also be a number). [5] A symbol that stands for an arbitrary input is called an independent variable, while a symbol that stands for an arbitrary output is called a dependent variable. [6]
In the following example sentences, independent clauses are underlined, and conjunctions are in bold. Single independent clauses: I have enough money to buy an ice cream cone. My favourite flavour is chocolate. Let's go to the shop. Multiple independent clauses: I have enough money to buy an ice cream cone; my favourite flavour is chocolate.
Complex sentences contain at least one clause subordinated to an independent clause (one that could stand alone as a simple sentence), which may be co-ordinated with other independents with or without dependents. Some dependent clauses are non-finite, i.e. they do not contain any element/verb marking a specific tense.
Albert Hofmann, the Swiss chemist who discovered LSD's psychedelic properties when he tried ingesting it at his lab, wrote It is true that my discovery of LSD was a chance discovery, but it was the outcome of planned experiments and these experiments took place in the framework of systematic pharmaceutical, chemical research.
These genes make up different DNA sequences, together called a genotype, that is specific to every given individual, within the gene pool of the population of a given species. The genotype, along with environmental and developmental factors, ultimately determines the phenotype of the individual.
Spearman's two-factor theory proposes that intelligence has two components: general intelligence ("g") and specific ability ("s"). [7] To explain the differences in performance on different tasks, Spearman hypothesized that the "s" component was specific to a certain aspect of intelligence.
