Article: Stochastic computing was first introduced in a pioneering paper by von Neumann in 1953. However, the theory could not be implemented until advances in computing of the 1960s. He also created the field of cellular automata without the aid of computers, constructing the first self-replicating automata with pencil and graph paper. The concept of a universal constructor was fleshed out in his posthumous work Theory of Self Reproducing Automata. Von Neumann proved that the most effective way of performing large-scale mining operations such as mining an entire moon or asteroid belt would be by using self-replicating spacecraft, taking advantage of their exponential growth. His rigorous mathematical analysis of the structure of self-replication (of the semiotic relationship between constructor, description and that which is constructed), preceded the discovery of the structure of DNA. Beginning in 1949, von Neumann's design for a self-reproducing computer program is considered the world's first computer virus, and he is considered to be the theoretical father of computer virology.

Question: What is another name for the first self reproducing computer program?
Ans: computer virus


Article: Since the early 1960s, theoretical linguists have moved away from the traditional concept of a phoneme, preferring to consider basic units at a more abstract level, as a component of morphemes; these units can be called morphophonemes, and analysis using this approach is called morphophonology.

Question: What kind of linguists are leaving the old methods behind?
Ans: theoretical


Article: House also had an influence of relaying political messages to people who were considered to be outcasts of society. The music appealed to those who didn't fit into mainstream American society and was especially celebrated by many black males. Frankie Knuckles once said that the Warehouse club in Chicago was like "church for people who have fallen from grace" The house producer Marshall Jefferson compared it to "old-time religion in the way that people just get happy and screamin'". Deep house was similar to many of the messages of freedom for the black community.

Question: Who did Frankie Knuckles once say the Warehouse club was for? 
Ans: church for people who have fallen from grace


Article: Hunting-gathering was the common human mode of subsistence throughout the Paleolithic, but the observation of current-day hunters and gatherers does not necessarily reflect Paleolithic societies; the hunter-gatherer cultures examined today have had much contact with modern civilization and do not represent "pristine" conditions found in uncontacted peoples.

Question: What type of conditions are not present in modern societies?
Ans:
pristine
