Schyrleus also included a map of the Moon in Oculus Enoch et Eliae. It was the first depiction of the Moon as seen in an inverting telescope (and thus the Moon itself is inverted in the illustration, with the South Pole at the top). The crater Tycho, for example, was depicted on lunar maps as early as 1645, when Schyrleus depicted the bright ray system. His map, however, did not come into standard use, as it was superseded by those made by Hevelius and the Jesuits Giovanni Battista Riccioli and Francesco Maria Grimaldi (1650–1651). In 1647, Schyrleus published a lunar chart with a diameter of 19 cm.[5]

In 2004, the Zürich venue became a problem for the organisers. Originally, the Hardturm stadium was to be renovated and used as the city's venue, but legal challenges delayed the plan to a point that would not have allowed the ground to be used in 2008. This created a problem, as the agreement between UEFA and the organizers stipulated that four venues would be used in each country. The problem was solved when the organizers proposed renovating Letzigrund instead; UEFA approved the revised plan in January 2005. The Letzigrund stadium hosted its first football match on 23 September 2007.[5]

Relief rain usually occurs along coastal areas where a line of hills runs along the coast. When wet onshore wind from the sea meets a mountain, hill or any other sort of barrier, it is forced to rise along the slope and cools. When the air temperature falls to its dew point, water vapour condenses to form clouds. When the clouds can no longer hold the water droplets, relief rain begins to fall on the windward slope of the mountain. On the leeward slope, air sinks, it is warmed and further dried by compression. Therefore, the leeward slope is known as rain shadow. Moist winds blow in from the sea and are forced to rise over the land. The air cools and the water vapour condenses, forming rain drops. Relief rain is also a very dense and cold mixture of precipitation.

Whether a fetus has the ability to feel pain and to suffer is part of the abortion debate. For example, in the USA legislation has been proposed by pro-life advocates that abortion providers should be required to tell a woman that the fetus may feel pain during the abortion procedure, and require her to accept or decline anesthesia for the fetus.

Liu Xiang wins gold in the 110 m hurdles, equalling Colin Jackson's 1993 world record time of 12.91 seconds. This was China's first ever gold in men's track and field.

Subtracting a positive nombor is equivalent to adding a negative nombor of equal absolute value; computers typically use two's complement notation to represent negative values. This notation eliminates the need for a separate ""subtract"" operation. Using two's complement notation subtraction can be summarized by the following formula:
