Problem: Immediately after reading Price's sermon, Burke wrote a draft of what eventually became, Reflections on the Revolution in France. On 13 February 1790, a notice in the press said that shortly, Burke would publish a pamphlet on the Revolution and its British supporters, however he spent the year revising and expanding it. On 1 November he finally published the Reflections and it was an immediate best-seller. Priced at five shillings, it was more expensive than most political pamphlets, but by the end of 1790, it had gone through ten printings and sold approximately 17,500 copies. A French translation appeared on 29 November and on 30 November the translator, Pierre-Gaëton Dupont, wrote to Burke saying 2,500 copies had already been sold. The French translation ran to ten printings by June 1791.
How much did most pamphlets cost at the time?

Problem: On the other hand, the crew on board the spaceship also perceives the observer as slowed down and flattened along the spaceship's direction of travel, because both are moving at very nearly the speed of light relative to each other. Because the outside universe appears flattened to the spaceship, the crew perceives themselves as quickly traveling between regions of space that (to the stationary observer) are many light years apart. This is reconciled by the fact that the crew's perception of time is different from the stationary observer's; what seems like seconds to the crew might be hundreds of years to the stationary observer. In either case, however, causality remains unchanged: the past is the set of events that can send light signals to an entity and the future is the set of events to which an entity can send light signals.
The crew's perception of what is different from a stationary observer?
---
Answer: time


Problem: A similar situation occurs with waders (called shorebirds in North America). Many species, such as dunlin Calidris alpina and western sandpiper Calidris mauri, undertake long movements from their Arctic breeding grounds to warmer locations in the same hemisphere, but others such as semipalmated sandpiper C. pusilla travel longer distances to the tropics in the Southern Hemisphere.
Where do dunlin Calidris alpina migrate to?
---
Answer:
warmer locations in the same hemisphere
