Von Neumann's famous 9-page paper started life as a talk at Princeton and then became a paper in Germany, which was eventually translated into English. His interest in economics that led to that paper began as follows: When lecturing at Berlin in 1928 and 1929 he spent his summers back home in Budapest, and so did the economist Nicholas Kaldor, and they hit it off. Kaldor recommended that von Neumann read a book by the mathematical economist Leon Walras. Von Neumann found some faults in that book and corrected them, for example, replacing equations by inequalities. He noticed that Walras's General Equilibrium Theory and Walras' Law, which led to systems of simultaneous linear equations, could produce the absurd result that the profit could be maximized by producing and selling a negative quantity of a product. He replaced the equations by inequalities, introduced dynamic equilibria, among other things, and eventually produced the paper.

In who's book did von Neuman find errors in the author's equations?
Answer: Leon Walras

When the Archbishop of Canterbury, Hubert Walter, died on 13 July 1205, John became involved in a dispute with Pope Innocent III that would lead to the king's excommunication. The Norman and Angevin kings had traditionally exercised a great deal of power over the church within their territories. From the 1040s onwards, however, successive popes had put forward a reforming message that emphasised the importance of the church being "governed more coherently and more hierarchically from the centre" and established "its own sphere of authority and jurisdiction, separate from and independent of that of the lay ruler", in the words of historian Richard Huscroft. After the 1140s, these principles had been largely accepted within the English church, albeit with an element of concern about centralising authority in Rome. These changes brought the customary rights of lay rulers such as John over ecclesiastical appointments into question. Pope Innocent was, according to historian Ralph Turner, an "ambitious and aggressive" religious leader, insistent on his rights and responsibilities within the church.

Who said Pope Innocent was an ambitious and aggressive religious leader?
Answer: historian Ralph Turner

Communication is usually described along a few major dimensions: Message (what type of things are communicated), source / emisor / sender / encoder (by whom), form (in which form), channel (through which medium), destination / receiver / target / decoder (to whom), and Receiver. Wilbur Schram (1954) also indicated that we should also examine the impact that a message has (both desired and undesired) on the target of the message. Between parties, communication includes acts that confer knowledge and experiences, give advice and commands, and ask questions. These acts may take many forms, in one of the various manners of communication. The form depends on the abilities of the group communicating. Together, communication content and form make messages that are sent towards a destination. The target can be oneself, another person or being, another entity (such as a corporation or group of beings).

Who said that we should examine the impact a message has on the recipient of the message?
Answer:
Wilbur Schram
