Article: The axiom of foundation established that every set can be constructed from the bottom up in an ordered succession of steps by way of the principles of Zermelo and Fraenkel, in such a manner that if one set belongs to another then the first must necessarily come before the second in the succession, hence excluding the possibility of a set belonging to itself. To demonstrate that the addition of this new axiom to the others did not produce contradictions, von Neumann introduced a method of demonstration, called the method of inner models, which later became an essential instrument in set theory.

Question: What is the method to demonstrate that no contradictions were created by the addition of axiom of foundation?
Ans: method of inner models

Article: One early attempt at lengthening the playing time should be mentioned. At least one manufacturer in the early 1920s, World Records, produced records that played at a constant linear velocity, controlled by Noel Pemberton Billing's patented add-on governor device. As these were played from the outside to the inside, the rotational speed of the records increased as reproduction progressed. This action is similar (although in reverse) to that on the modern compact disc and the CLV version of its predecessor, the Philips Laser Disc.

Question: What was a unique feature of World Records records?
Ans: played from the outside to the inside

Article: On 20 June 1794, Burke received a vote of thanks from the Commons for his services in the Hastings Trial and he immediately resigned his seat, being replaced by his son Richard. A tragic blow fell upon Burke with the loss of Richard in August 1794, to whom he was tenderly attached, and in whom he saw signs of promise, which were not patent to others and which, in fact, appear to have been non-existent (though this view may have rather reflected the fact that Richard Burke had worked successfully in the early battle for Catholic emancipation). King George III, whose favour he had gained by his attitude on the French Revolution, wished to create him Earl of Beaconsfield, but the death of his son deprived the opportunity of such an honour and all its attractions, so the only award he would accept was a pension of 2,500. Even this modest reward was attacked by the Duke of Bedford and the Earl of Lauderdale, to whom Burke replied in his Letter to a Noble Lord (1796): "It cannot at this time be too often repeated; line upon line; precept upon precept; until it comes into the currency of a proverb, To innovate is not to reform". He argued that he was rewarded on merit, but the Duke of Bedford received his rewards from inheritance alone, his ancestor being the original pensioner: "Mine was from a mild and benevolent sovereign; his from Henry the Eighth". Burke also hinted at what would happen to such people if their revolutionary ideas were implemented, and included a description of the British constitution:

Question: When did Burke's son die?
Ans: August 1794

Article: A tile mosaic is a digital image made up of individual tiles, arranged in a non-overlapping fashion, e.g. to make a static image on a shower room or bathing pool floor, by breaking the image down into square pixels formed from ceramic tiles (a typical size is 1 in 1 in (25 mm 25 mm), as for example, on the floor of the University of Toronto pool, though sometimes larger tiles such as 2 in 2 in (51 mm 51 mm) are used). These digital images are coarse in resolution and often simply express text, such as the depth of the pool in various places, but some such digital images are used to show a sunset or other beach theme.

Question: How should the tiles be aligned next to each other?
Ans:
in a non-overlapping fashion
