Beginning in the late 1910s and early 1920s, Whitehead gradually turned his attention from mathematics to philosophy of science, and finally to metaphysics. He developed a comprehensive metaphysical system which radically departed from most of western philosophy. Whitehead argued that reality consists of processes rather than material objects, and that processes are best defined by their relations with other processes, thus rejecting the theory that reality is fundamentally constructed by bits of matter that exist independently of one another. Today Whitehead's philosophical works particularly Process and Reality are regarded as the foundational texts of process philosophy.

What did Whitehead first study?
Answer: mathematics

Problem: Melatonin is absent from the system or undetectably low during daytime. Its onset in dim light, dim-light melatonin onset (DLMO), at roughly 21:00 (9 p.m.) can be measured in the blood or the saliva. Its major metabolite can also be measured in morning urine. Both DLMO and the midpoint (in time) of the presence of the hormone in the blood or saliva have been used as circadian markers. However, newer research indicates that the melatonin offset may be the more reliable marker. Benloucif et al. found that melatonin phase markers were more stable and more highly correlated with the timing of sleep than the core temperature minimum. They found that both sleep offset and melatonin offset are more strongly correlated with phase markers than the onset of sleep. In addition, the declining phase of the melatonin levels is more reliable and stable than the termination of melatonin synthesis.
The presence of what is a circadian marker?
The answer is the following: hormone

For instance, if a transmitter delivers 100 W into an antenna having an efficiency of 80%, then the antenna will radiate 80 W as radio waves and produce 20 W of heat. In order to radiate 100 W of power, one would need to use a transmitter capable of supplying 125 W to the antenna. Note that antenna efficiency is a separate issue from impedance matching, which may also reduce the amount of power radiated using a given transmitter. If an SWR meter reads 150 W of incident power and 50 W of reflected power, that means that 100 W have actually been absorbed by the antenna (ignoring transmission line losses). How much of that power has actually been radiated cannot be directly determined through electrical measurements at (or before) the antenna terminals, but would require (for instance) careful measurement of field strength. Fortunately the loss resistance of antenna conductors such as aluminum rods can be calculated and the efficiency of an antenna using such materials predicted.
What factor may play a hand in lessened power from a transmitter?
impedance matching

Input: Sahara
The central part of the Sahara is hyperarid, with little to no vegetation. The northern and southern reaches of the desert, along with the highlands, have areas of sparse grassland and desert shrub, with trees and taller shrubs in wadis where moisture collects. In the central, hyperarid part, there are many subdivisions of the great desert such as the Tanezrouft, the Tenere, the Libyan Desert, the Eastern Desert, the Nubian Desert and others. These absolute desert regions are characterized by their extreme aridity, and some years can pass without any rainfall.

What is the central part of the Sahara Desert?
Output: hyperarid

Input: Article: Since Whitehead's metaphysics described a universe in which all entities experience, he needed a new way of describing perception that was not limited to living, self-conscious beings. The term he coined was "prehension", which comes from the Latin prehensio, meaning "to seize." The term is meant to indicate a kind of perception that can be conscious or unconscious, applying to people as well as electrons. It is also intended to make clear Whitehead's rejection of the theory of representative perception, in which the mind only has private ideas about other entities. For Whitehead, the term "prehension" indicates that the perceiver actually incorporates aspects of the perceived thing into itself. In this way, entities are constituted by their perceptions and relations, rather than being independent of them. Further, Whitehead regards perception as occurring in two modes, causal efficacy (or "physical prehension") and presentational immediacy (or "conceptual prehension").

Now answer this question: What is a basic description of the theory of representative perception?

Output: the mind only has private ideas about other entities

Problem: Dorgon's controversial July 1645 edict (the "haircutting order") forced adult Han Chinese men to shave the front of their heads and comb the remaining hair into the queue hairstyle which was worn by Manchu men, on pain of death. The popular description of the order was: "To keep the hair, you lose the head; To keep your head, you cut the hair." To the Manchus, this policy was a test of loyalty and an aid in distinguishing friend from foe. For the Han Chinese, however, it was a humiliating reminder of Qing authority that challenged traditional Confucian values. The Classic of Filial Piety (Xiaojing) held that "a person's body and hair, being gifts from one's parents, are not to be damaged." Under the Ming dynasty, adult men did not cut their hair but instead wore it in the form of a top-knot. The order triggered strong resistance to Qing rule in Jiangnan and massive killing of ethnic Han Chinese. It was Han Chinese defectors who carried out massacres against people refusing to wear the queue.. Li Chengdong, a Han Chinese general who had served the Ming but surrendered to the Qing, ordered his Han troops to carry out three separate massacres in the city of Jiading within a month, resulting in tens of thousands of deaths. At the end of the third massacre, there was hardly any living person left in this city. Jiangyin also held out against about 10,000 Han Chinese Qing troops for 83 days. When the city wall was finally breached on 9 October 1645, the Han Chinese Qing army led by the Han Chinese Ming defector Liu Liangzuo (), who had been ordered to "fill the city with corpses before you sheathe your swords," massacred the entire population, killing between 74,000 and 100,000 people. The queue was the only aspect of Manchu culture which the Qing forced on the common Han population. The Qing required people serving as officials to wear Manchu clothing, but allowed non-official Han civilians to continue wearing Hanfu (Han clothing).
How did the Ming's typically wear their hair>
The answer is the following:
top-knot
