Input: Read this: Luminous efficacy of a light source may be defined in two ways. The radiant luminous efficacy (LER) is the ratio of the visible light flux emitted (the luminous flux) to the total power radiated over all wavelengths. The source luminous efficacy (LES) is the ratio of the visible light flux emitted (the luminous flux) to the total power input to the source, such as a lamp. Visible light is measured in lumens, a unit which is defined in part by the differing sensitivity of the human eye to different wavelengths of light. Not all wavelengths of visible electromagnetic energy are equally effective at stimulating the human eye; the luminous efficacy of radiant energy (LER) is a measure of how well the distribution of energy matches the perception of the eye. The units of luminous efficacy are "lumens per watt" (lpw). The maximum LER possible is 683 lm/W for monochromatic green light at 555 nanometers wavelength, the peak sensitivity of the human eye.
Question: In how many ways can one define luminous efficacy of a light source?

Output: two ways

QUES: He attained a perfect score on the graduate school entrance exams to Princeton University in mathematics and physicsan unprecedented featbut did rather poorly on the history and English portions. Attendees at Feynman's first seminar included Albert Einstein, Wolfgang Pauli, and John von Neumann. He received a PhD from Princeton in 1942; his thesis advisor was John Archibald Wheeler. Feynman's thesis applied the principle of stationary action to problems of quantum mechanics, inspired by a desire to quantize the WheelerFeynman absorber theory of electrodynamics, laying the groundwork for the "path integral" approach and Feynman diagrams, and was titled "The Principle of Least Action in Quantum Mechanics".

Which two sections of the graduate exam did Feynman excel in?
What is the answer?
ANS: mathematics and physics

QUES: In a book called Science Versus Crime, Houck writes that Popper's falsificationism can be questioned logically: it is not clear how Popper would deal with a statement like "for every metal, there is a temperature at which it will melt." The hypothesis cannot be falsified by any possible observation, for there will always be a higher temperature than tested at which the metal may in fact melt, yet it seems to be a valid scientific hypothesis. These examples were pointed out by Carl Gustav Hempel. Hempel came to acknowledge that Logical Positivism's verificationism was untenable, but argued that falsificationism was equally untenable on logical grounds alone. The simplest response to this is that, because Popper describes how theories attain, maintain and lose scientific status, individual consequences of currently accepted scientific theories are scientific in the sense of being part of tentative scientific knowledge, and both of Hempel's examples fall under this category. For instance, atomic theory implies that all metals melt at some temperature.
Which book by Houck points out logical flaws in Popper's falsificationism?

Greece's foreign policy is conducted through the Ministry for Foreign Affairs and its head, the Minister for Foreign Affairs. The current minister is Nikos Kotzias. According to the official website, the main aims of the Ministry for Foreign Affairs are to represent Greece before other states and international organizations; safeguarding the interests of the Greek state and of its citizens abroad; the promotion of Greek culture; the fostering of closer relations with the Greek diaspora; and the promotion of international cooperation. Additionally, due to its political and geographical proximity to Europe, Asia, the Middle East and Africa, Greece is a country of significant geostrategic importance and is considered to be a middle power and has developed a regional policy to help promote peace and stability in the Balkans, the Mediterranean, and the Middle East.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Greece is though of as what kind of power?
Ah, so.. a middle power

Question: Jefferson's letter entered American jurisprudence in the 1878 Mormon polygamy case Reynolds v. U.S., in which the court cited Jefferson and Madison, seeking a legal definition for the word religion. Writing for the majority, Justice Stephen Johnson Field cited Jefferson's Letter to the Danbury Baptists to state that "Congress was deprived of all legislative power over mere opinion, but was left free to reach actions which were in violation of social duties or subversive of good order." Considering this, the court ruled that outlawing polygamy was constitutional.
Try to answer this question if possible: What was the topic of Reynolds v. U.S.?
Answer: Mormon polygamy

Question: Another occasionally used criterion for discriminating dialects from languages is that of linguistic authority, a more sociolinguistic notion. According to this definition, two varieties are considered dialects of the same language if (under at least some circumstances) they would defer to the same authority regarding some questions about their language. For instance, to learn the name of a new invention, or an obscure foreign species of plant, speakers of Bavarian German and East Franconian German might each consult a German dictionary or ask a German-speaking expert in the subject. By way of contrast, although Yiddish is classified by linguists as a language in the "Middle High German" group of languages, a Yiddish speaker would not consult a German dictionary to determine the word to use in such a case.
Try to answer this question if possible: What term refers to another way in which dialects are distinguished from languages?
Answer:
linguistic authority
