Article: Often, through-hole and surface-mount construction must be combined in a single assembly because some required components are available only in surface-mount packages, while others are available only in through-hole packages. Another reason to use both methods is that through-hole mounting can provide needed strength for components likely to endure physical stress, while components that are expected to go untouched will take up less space using surface-mount techniques. For further comparison, see the SMT page.

Question: Surface-mount is one type of construction used in PCB assembly; what's the other one?
Ans: through-hole

Article: Enlightenment historiography began in the period itself, from what Enlightenment figures said about their work. A dominant element was the intellectual angle they took. D'Alembert's Preliminary Discourse of l'Encyclopedie provides a history of the Enlightenment which comprises a chronological list of developments in the realm of knowledge of which the Encyclopedie forms the pinnacle. In 1783, Jewish philosopher Moses Mendelssohn referred to Enlightenment as a process by which man was educated in the use of reason. Immanuel Kant called Enlightenment "man's release from his self-incurred tutelage", tutelage being "man's inability to make use of his understanding without direction from another". "For Kant, Enlightenment was mankind's final coming of age, the emancipation of the human consciousness from an immature state of ignorance." The German scholar Ernst Cassirer called the Enlightenment "a part and a special phase of that whole intellectual development through which modern philosophic thought gained its characteristic self-confidence and self-consciousness". According to historian Roy Porter, the liberation of the human mind from a dogmatic state of ignorance is the epitome of what the Age of Enlightenment was trying to capture.

Question: How did Immanuel Kant describe the Enlightenment?
Ans: "man's release from his self-incurred tutelage"

Article: A large number of international institutions have their seats in Switzerland, in part because of its policy of neutrality. Geneva is the birthplace of the Red Cross and Red Crescent Movement and the Geneva Conventions and, since 2006, hosts the United Nations Human Rights Council. Even though Switzerland is one of the most recent countries to have joined the United Nations, the Palace of Nations in Geneva is the second biggest centre for the United Nations after New York, and Switzerland was a founding member and home to the League of Nations.

Question: How long has Switzerland hosted the United Nations Human Rights Council?
Ans: since 2006

Article: Time has historically been closely related with space, the two together merging into spacetime in Einstein's special relativity and general relativity. According to these theories, the concept of time depends on the spatial reference frame of the observer, and the human perception as well as the measurement by instruments such as clocks are different for observers in relative motion. For example, if a spaceship carrying a clock flies through space at (very nearly) the speed of light, its crew does not notice a change in the speed of time on board their vessel because everything traveling at the same speed slows down at the same rate (including the clock, the crew's thought processes, and the functions of their bodies). However, to a stationary observer watching the spaceship fly by, the spaceship appears flattened in the direction it is traveling and the clock on board the spaceship appears to move very slowly.

Question: Historically, time has been closely related with what?
Ans:
space
