Question: The reason for this is that a quantum disjunction, unlike the case for classical disjunction, can be true even when both of the disjuncts are false and this is, in turn, attributable to the fact that it is frequently the case, in quantum mechanics, that a pair of alternatives are semantically determinate, while each of its members are necessarily indeterminate. This latter property can be illustrated by a simple example. Suppose we are dealing with particles (such as electrons) of semi-integral spin (angular momentum) for which there are only two possible values: positive or negative. Then, a principle of indetermination establishes that the spin, relative to two different directions (e.g., x and y) results in a pair of incompatible quantities. Suppose that the state of a certain electron verifies the proposition "the spin of the electron in the x direction is positive." By the principle of indeterminacy, the value of the spin in the direction y will be completely indeterminate for . Hence, can verify neither the proposition "the spin in the direction of y is positive" nor the proposition "the spin in the direction of y is negative." Nevertheless, the disjunction of the propositions "the spin in the direction of y is positive or the spin in the direction of y is negative" must be true for . In the case of distribution, it is therefore possible to have a situation in which , while .
Is there an answer to this question: What is frequently the case in quantum mechanics when a pair of alternatives are semantically determinate?

Answer: each of its members are necessarily indeterminate

Question: The Old Swiss Confederacy had acquired a reputation of invincibility during these earlier wars, but expansion of the federation suffered a setback in 1515 with the Swiss defeat in the Battle of Marignano. This ended the so-called "heroic" epoch of Swiss history. The success of Zwingli's Reformation in some cantons led to inter-cantonal religious conflicts in 1529 and 1531 (Wars of Kappel). It was not until more than one hundred years after these internal wars that, in 1648, under the Peace of Westphalia, European countries recognized Switzerland's independence from the Holy Roman Empire and its neutrality.
Is there an answer to this question: In what year did European countries first recognize Switzerland's independence from the Holy Roman Empire?

Answer: 1648

Question: Plymouth has a post-war shopping area in the city centre with substantial pedestrianisation. At the west end of the zone inside a grade II listed building is the Pannier Market that was completed in 1959 pannier meaning "basket" from French, so it translates as "basket market". In terms of retail floorspace, Plymouth is ranked in the top five in the South West, and 29th nationally. Plymouth was one of the first ten British cities to trial the new Business Improvement District initiative. The Tinside Pool is situated at the foot of the Hoe and became a grade II listed building in 1998 before being restored to its 1930s look for 3.4 million.
Is there an answer to this question: What was the cost to restore Tinside Pool?

Answer: 3.4 million

Question: The New Haven Division buses follow routes that had originally been covered by trolley service. Horse-drawn steetcars began operating in New Haven in the 1860s, and by the mid-1890s all the lines had become electric. In the 1920s and 1930s, some of the trolley lines began to be replaced by bus lines, with the last trolley route converted to bus in 1948. The City of New Haven is in the very early stages of considering the restoration of streetcar (light-rail) service, which has been absent since the postwar period.
Is there an answer to this question: What further ideas for public transportation is the city currently considering?

Answer:
streetcar (light-rail) service
