Passage: Energy gives rise to weight when it is trapped in a system with zero momentum, where it can be weighed. It is also equivalent to mass, and this mass is always associated with it. Mass is also equivalent to a certain amount of energy, and likewise always appears associated with it, as described in mass-energy equivalence. The formula E = mc, derived by Albert Einstein (1905) quantifies the relationship between rest-mass and rest-energy within the concept of special relativity. In different theoretical frameworks, similar formulas were derived by J. J. Thomson (1881), Henri Poincare (1900), Friedrich Hasenohrl (1904) and others (see Mass-energy equivalence#History for further information). Question: In what year did Einstein create E = mc2?
1905

Passage: Western political philosophy originates in the philosophy of ancient Greece, where political philosophy dates back to at least Plato. Ancient Greece was dominated by city-states, which experimented with various forms of political organization, grouped by Plato into four categories: timocracy, tyranny, democracy and oligarchy.

Roman political philosophy was influenced by the Stoics, including the Roman statesman Cicero. Question: Western political philosophy originates in what philosophy?

Passage: The Canadian constitution determines that the Commander-in-Chief of the Canadian Armed Forces is the country's sovereign, who, since 1904, has authorized his or her viceroy, the governor general, to exercise the duties ascribed to the post of Commander-in-Chief and to hold the associated title since 1905. All troop deployment and disposition orders, including declarations of war, fall within the royal prerogative and are issued as Orders in Council, which must be signed by either the monarch or governor general. Under the Westminster system's parliamentary customs and practices, however, the monarch and viceroy must generally follow the advice of his or her ministers in Cabinet, including the prime minister and minister of national defence, who are accountable to the elected House of Commons. Question: Who does the Commander-in-Chief authorize to make decision regarding the Armed Forces for them?
the governor general
