Article: In 1974, Feynman delivered the Caltech commencement address on the topic of cargo cult science, which has the semblance of science, but is only pseudoscience due to a lack of "a kind of scientific integrity, a principle of scientific thought that corresponds to a kind of utter honesty" on the part of the scientist. He instructed the graduating class that "The first principle is that you must not fool yourselfand you are the easiest person to fool. So you have to be very careful about that. After you've not fooled yourself, it's easy not to fool other scientists. You just have to be honest in a conventional way after that."

Question: Which topic did Feynman's commencement speech at Caltech center around?
Ans: cargo cult science

Article: Two groups G and H are called isomorphic if there exist group homomorphisms a: G H and b: H G, such that applying the two functions one after another in each of the two possible orders gives the identity functions of G and H. That is, a(b(h)) = h and b(a(g)) = g for any g in G and h in H. From an abstract point of view, isomorphic groups carry the same information. For example, proving that g g = 1G for some element g of G is equivalent to proving that a(g) a(g) = 1H, because applying a to the first equality yields the second, and applying b to the second gives back the first.

Question: What are two groups called if they include homomorphisms?
Ans: isomorphic

Article: Georgian architecture is the name given in most English-speaking countries to the set of architectural styles current between 1714 and 1830. It is eponymous for the first four British monarchs of the House of HanoverGeorge I, George II, George III, and George IVwho reigned in continuous succession from August 1714 to June 1830. The style was revived in the late 19th century in the United States as Colonial Revival architecture and in the early 20th century in Great Britain as Neo-Georgian architecture; in both it is also called Georgian Revival architecture. In America the term "Georgian" is generally used to describe all building from the period, regardless of style; in Britain it is generally restricted to buildings that are "architectural in intention", and have stylistic characteristics that are typical of the period, though that covers a wide range.

Question: What was the name given to the 20th century Great British revival Georgian architecture.
Ans: Neo-Georgian

Article: Bipolar transistors are so named because they conduct by using both majority and minority carriers. The bipolar junction transistor, the first type of transistor to be mass-produced, is a combination of two junction diodes, and is formed of either a thin layer of p-type semiconductor sandwiched between two n-type semiconductors (an npn transistor), or a thin layer of n-type semiconductor sandwiched between two p-type semiconductors (a pnp transistor). This construction produces two pn junctions: a baseemitter junction and a basecollector junction, separated by a thin region of semiconductor known as the base region (two junction diodes wired together without sharing an intervening semiconducting region will not make a transistor).

Question: What was the first mass-produced transistor?
Ans:
bipolar junction transistor
