Some context: Martina Hingis (born 30 September 1980) is a Swiss former professional tennis player who spent a total of 209 weeks as the singles world No. 1 and 90 weeks as doubles world No. 1, holding both No. 1 rankings simultaneously for 29 weeks. She won five Grand Slam singles titles, thirteen Grand Slam women's doubles titles, winning a calendar-year doubles Grand Slam in 1998, and seven Grand Slam mixed doubles titles; for a combined total of twenty-five major titles. In addition, she won the season-ending WTA Finals two times in singles and three times in doubles, and an Olympic silver medal.
Hingis helped Sabine Lisicki during the 2014 Australian Open. She participated in Champions Tennis League India to boost tennis in the country.  Hingis returned to the WTA Tour at Indian Wells, partnering Sabine Lisicki in the doubles. They lost in the first round to 3-time Grand Slam finalists Ashleigh Barty and Casey Dellacqua. At the 2014 Sony Open Tennis in Miami, Hingis and Lisicki reached the finals of the tournament and then defeated Ekaterina Makarova and Elena Vesnina in straight sets, marking Hingis' first title since she won the Qatar Ladies Open in 2007 and her first Premier Mandatory doubles title since winning the 2001 title in Moscow. This was also her third win in Miami, having won her last title there in 1999.  Hingis reached the final at Eastbourne with Flavia Pennetta where they lost to Hao-Ching Chan and Yung-Jan Chan of Taiwan. At the 2014 Wimbledon Championships, she reached the quarter-finals with partner Bruno Soares in mixed doubles, where they lost to Daniel Nestor and Kristina Mladenovic in straight sets.  Entering as an unseeded team at the 2014 US Open, Hingis and Pennetta reached the final, without losing a set in any of their matches. In the final they lost to Ekaterina Makarova and Elena Vesnina in three sets.  At the latter end of the season, Hingis and Flavia Pennetta won two titles. At the tournament in Wuhan, they beat Cara Black and Caroline Garcia to take the title; in Moscow they beat Caroline Garcia and Arantxa Parra Santonja.

Some context: David Kellogg Lewis (September 28, 1941 - October 14, 2001) was an American philosopher. Lewis taught briefly at UCLA and then at Princeton from 1970 until his death. He is also closely associated with Australia, whose philosophical community he visited almost annually for more than thirty years. He made contributions in philosophy of language, philosophy of mind, philosophy of probability, metaphysics, epistemology, philosophical logic, and aesthetics.
Lewis went on to publish Counterfactuals (1973), which contained an analysis of Counterfactual conditionals in terms of the theory of possible worlds. He had already proposed it in some of his earlier papers: "Counterpart Theory and Quantified Modal Logic" (1968), "Anselm and Actuality" (1970), and "Counterparts of Persons and their Bodies" (1971). In spite of significant technical advantages promised by this approach, the theory was widely considered to be too implausible to be taken literally, as Lewis urged it should be. Most often the idea that there exists an infinite number of causally isolated universes, each as real as our own but different from it in some way, and that furthermore that alluding to objects in this universe as necessary in order to explain what makes certain counterfactual statements true but not others, meets with what Lewis calls the "incredulous stare" (Lewis, OPW, 2005, pg. 135-137). Lewis defends and elaborates his theory of extreme modal realism, while insisting that there is nothing extreme about it, in On the Plurality of Worlds (1986). Lewis acknowledges that his theory is contrary to common sense, but believes that its advantages far outweigh this disadvantage, and that therefore we should not be hesitant to pay this price.  According to Lewis, what makes a counterfactual conditional of the form  "Had I made that shot our team would have won the game."  true is that there is a world, as concrete as ours and significantly similar to it, in which my counterpart makes rather than misses the shot and the counterpart of our team wins the game. Had there been a world even more similar to ours in which my counterpart makes the shot but the counterpart of our team still loses the counterfactual would have been false. When we speak of counterfactual possibilities we speak of what is the case in some possible world or worlds. According to Lewis, "actual" is merely an indexical label we give to a world when we locate ourselves in it. Things are necessarily true when they are true in all possible worlds. (Note that Lewis is not the first one to speak of possible worlds in this context. Leibniz and C.I. Lewis, for example, both speak of possible worlds as a way of thinking about possibility and necessity, and some of David Kaplan's early work is on the counterpart theory. Lewis's original suggestion was that all possible worlds are equally concrete, and the world in which we find ourselves is no more real than any other possible world.)

Some context: Tedder was born the son of Sir Arthur John Tedder and Emily Charlotte Tedder (nee Bryson) at the Glenguin Distillery (now Glengoyne) in the Campsie Fells, north of Glasgow. His father was distinguished as the Commissioner of the Board of Customs who devised the old age pension scheme. His father's occupation meant that the young Tedder saw different parts of the British Isles, spending 1895 to 1898 in Lerwick on the Shetland Isles and 1899-1901 in Elgin, in the County of Moray. In 1902 the family moved to Croydon in Surrey and Tedder attended the Whitgift School until 1909, when he went up to the University of Cambridge.
Tedder was promoted to lieutenant in the Dorset Regiment on 14 October 1914, and arrived back in Britain in December. He was posted to a reserve unit at Wyke Regis on the Dorset coast where he seriously injured his knee in February. Following his injury Tedder was unable to carry out full infantry service and, although he briefly carried out duties at a base camp in Calais, he pressed for a transfer to the Royal Flying Corps.  In January 1916, Tedder was accepted into the Royal Flying Corps and he was asked to attend the No. 1 School of Aeronautics. in Reading. He was promoted to captain on 21 March 1916. In April he attended the Central Flying School where he learned to fly and gained his 'wings'. In June 1916, Tedder served as a pilot with No. 25 Squadron RFC flying the Bristol Scout C on the Western Front. On 9 August 1916, Tedder was given additional responsibilities as he was made a flight commander with 25 Squadron. The first day of 1917 saw Tedder promoted to major and appointed officer commanding No. 70 Squadron RFC. Tedder remained on the Western Front and his new squadron was equipped with the Sopwith 1 1/2  Strutter. He was awarded the Italian Silver Medal for Military Valour on 26 May 1917.  Tedder was appointed officer commanding No. 67 Squadron at RFC Shawbury on 25 June 1917 and became commander of the School of Navigation and Bomb Dropping in Egypt the following year. Another change soon followed and on 24 June 1918 Tedder was appointed officer commanding 38th Wing, also based in Egypt. He was promoted to the temporary rank of lieutenant colonel on 23 July 1918 (rank relinquished on 2 April 1919).
