Question: Washington, D.C. is often mentioned as a candidate for statehood. In Federalist No. 43 of The Federalist Papers, James Madison considered the implications of the definition of the "seat of government" found in the United States Constitution. Although he noted potential conflicts of interest, and the need for a "municipal legislature for local purposes," Madison did not address the district's role in national voting. Legal scholars disagree on whether a simple act of Congress can admit the District as a state, due to its status as the seat of government of the United States, which Article I, Section 8 of the Constitution requires to be under the exclusive jurisdiction of Congress; depending on the interpretation of this text, admission of the full District as a state may require a Constitutional amendment, which is much more difficult to enact. However, the Constitution does not set a minimum size for the District. Its size has already changed once before, when Virginia reclaimed the portion of the District south of the Potomac. So the constitutional requirement for a federal district can be satisfied by reducing its size to the small central core of government buildings and monuments, giving the rest of the territory to the new state.
Is there an answer to this question: Where are these ideas located in the Federalist Papers?

Answer: Federalist No. 43


Question: The X-ray crystal density method is primarily a method for determining the Avogadro constant NA but as the Avogadro constant is related to the Planck constant it also determines a value for h. The principle behind the method is to determine NA as the ratio between the volume of the unit cell of a crystal, measured by X-ray crystallography, and the molar volume of the substance. Crystals of silicon are used, as they are available in high quality and purity by the technology developed for the semiconductor industry. The unit cell volume is calculated from the spacing between two crystal planes referred to as d220. The molar volume Vm(Si) requires a knowledge of the density of the crystal and the atomic weight of the silicon used. The Planck constant is given by
Is there an answer to this question: The Avogadro constant is determined to be the ratio between what two factors in the X-ray crystal density method?

Answer: the volume of the unit cell of a crystal, measured by X-ray crystallography, and the molar volume of the substance


Question: When Ibn Sina was 22 years old, he lost his father. The Samanid dynasty came to its end in December 1004. Ibn Sina seems to have declined the offers of Mahmud of Ghazni, and proceeded westwards to Urgench in modern Turkmenistan, where the vizier, regarded as a friend of scholars, gave him a small monthly stipend. The pay was small, however, so Ibn Sina wandered from place to place through the districts of Nishapur and Merv to the borders of Khorasan, seeking an opening for his talents. Qabus, the generous ruler of Tabaristan, himself a poet and a scholar, with whom Ibn Sina had expected to find asylum, was on about that date (1012) starved to death by his troops who had revolted. Ibn Sina himself was at this time stricken by a severe illness. Finally, at Gorgan, near the Caspian Sea, Ibn Sina met with a friend, who bought a dwelling near his own house in which Ibn Sina lectured on logic and astronomy. Several of Ibn Sina's treatises were written for this patron; and the commencement of his Canon of Medicine also dates from his stay in Hyrcania.
Is there an answer to this question: What did Ibn Sina write while in Urgench?

Answer: unanswerable


Question: Starting in 1236, the Mongol prince Kublai, who later ruled as Khagan from 1260–1294, was granted a large appanage in North China by his superior, Ögedei Khan. Karma Pakshi, 2nd Karmapa Lama (1203–1283)—the head lama of the Karma Kagyu lineage of Tibetan Buddhism—rejected Kublai's invitation, so instead Kublai invited Drogön Chögyal Phagpa (1235–1280), successor and nephew of Sakya Pandita, who came to his court in 1253. Kublai instituted a unique relationship with the Phagpa lama, which recognized Kublai as a superior sovereign in political affairs and the Phagpa lama as the senior instructor to Kublai in religious affairs. Kublai also made Drogön Chögyal Phagpa the director of the government agency known as the Bureau of Buddhist and Tibetan Affairs and the ruling priest-king of Tibet, which comprised thirteen different states ruled by myriarchies.
Is there an answer to this question: Who was the superior of prince Kublai?

Answer:
Ögedei Khan
