Context and question: Due to reciprocity (discussed above) the gain of an antenna used for transmitting must be proportional to its effective area when used for receiving. Consider an antenna with no loss, that is, one whose electrical efficiency is 100%. It can be shown that its effective area averaged over all directions must be equal to 2/4, the wavelength squared divided by 4. Gain is defined such that the average gain over all directions for an antenna with 100% electrical efficiency is equal to 1. Therefore, the effective area Aeff in terms of the gain G in a given direction is given by:
Another term for the effective area is?
Answer: Aeff
Context and question: She has received co-writing credits for most of the songs recorded with Destiny's Child and her solo efforts. Her early songs were personally driven and female-empowerment themed compositions like "Independent Women" and "Survivor", but after the start of her relationship with Jay Z she transitioned to more man-tending anthems such as "Cater 2 U". Beyonce has also received co-producing credits for most of the records in which she has been involved, especially during her solo efforts. However, she does not formulate beats herself, but typically comes up with melodies and ideas during production, sharing them with producers.
What theme was Beyonce's early music?
Answer: female-empowerment
Context and question: Von Neumann entered government service (Manhattan Project) primarily because he felt that, if freedom and civilization were to survive, it would have to be because the US would triumph over totalitarianism from Nazism, Fascism and Soviet Communism. During a Senate committee hearing he described his political ideology as "violently anti-communist, and much more militaristic than the norm". He was quoted in 1950 remarking, "If you say why not bomb [the Soviets] tomorrow, I say, why not today? If you say today at five o'clock, I say why not one o'clock?"
Why did von Neumann join government work?
Answer:
felt that, if freedom and civilization were to survive, it would have to be because the US would triumph over totalitarianism
