Background: Lewis Fry Richardson was the youngest of seven children born to Catherine Fry (1838-1919) and David Richardson (1835-1913). They were a prosperous Quaker family, David Richardson operating a successful tanning and leather manufacturing business. At age 12 he was sent to a Quaker boarding school, Bootham School in York, where he received an education in science, which stimulated an active interest in natural history. In 1898 he went on to Durham College of Science (a college of Durham University) where he took courses in mathematical physics, chemistry, botany, and zoology.
Context: Richardson decided to search for a relation between the probability of two countries going to war and the length of their common border. However, while collecting data, he found that there was considerable variation in the various published lengths of international borders. For example, that between Spain and Portugal was variously quoted as 987 or 1214 km, and that between the Netherlands and Belgium as 380 or 449 km.  The reason for these inconsistencies is the "coastline paradox". Suppose the coast of Britain is measured using a 200 km ruler, specifying that both ends of the ruler must touch the coast. Now cut the ruler in half and repeat the measurement, then repeat:  Notice that the smaller the ruler, the longer the resulting coastline. It might be supposed that these values would converge to a finite number representing the true length of the coastline. However, Richardson demonstrated that this is not the case: the measured length of coastlines, and other natural features, increases without limit as the unit of measurement is made smaller. This is known nowadays as the Richardson effect.  At the time, Richardson's research was ignored by the scientific community. Today, it is considered an element of the beginning of the modern study of fractals. Richardson's research was quoted by mathematician Benoit Mandelbrot in his 1967 paper How Long Is the Coast of Britain? Richardson identified a value (between 1 and 2) that would describe the changes (with increasing measurement detail) in observed complexity for a particular coastline; this value served as a model for the concept of fractal dimension.
Question: What is he best known for?
Answer: Richardson effect.

Question:
Barclay was born in Chicago Heights, Illinois. He attended La Lumiere School, a private college preparatory boarding school in La Porte, Indiana. On scholarship, he was one of the first African-Americans to attend the school, Barclay went on to Harvard College, where he was extremely active in student musical theatre productions and the a cappella singing group The Harvard Krokodiloes.
Following his graduation from Harvard, he worked as a copywriter and creative supervisor at Grey, BBDO, Cunningham & Walsh, and Marsteller. Barclay then moved into music video directing and production through his own company, Black & White Television. He directed music videos for Bob Dylan ("It's Unbelievable"), the New Kids On The Block ("Games" ), Janet Jackson and Luther Vandross ("The Best Things in Life Are Free" ). Most notably, he created eight videos for LL Cool J, including "Mama Said Knock You Out", which won awards from both MTV and Billboard--and went on to be listed by The Rock and Roll Hall of Fame as one of the 500 songs that shaped rock and roll. In 2013, Complex Magazine ranked "Mama Said Knock You Out" as one of the top 50 rap videos of the 1990s, crediting it with creating "one of the most crucial links in establishing the cultural bridge between boxing and rap." Barclay was often hired to direct videos for films, introducing audiences to House Party (1990), White Men Can't Jump (1992), Mo' Money (1992), Posse (1993), and Cool Runnings (1993), among others.  In 2012, Barclay directed his first music video in 16 years, working once again with LL Cool J and R&B star Joe on the video for "Take It".  Also drawing on his music video experience was Barclay's episode ("The Coup") of the Steven Spielberg-produced NBC series Smash, in which TV Fanatic said that the Barclay-directed number for the original song "Touch Me" (written by OneRepublic's Ryan Tedder) "pushed the boundaries from traditional Broadway show to music video level."

Problem: Background: Baitullah Mehsud (Pashto,Urdu: byt llh mHswd); c. 1972 - c. 5 August 2009) was a leading militant in Waziristan, Pakistan, and the leader of the Tehrik-i-Taliban Pakistan (TTP). He formed the TTP from an alliance of about five militant groups in December 2007. He is thought by U.S. military analysts to have commanded up to 5,000 fighters and to have been behind numerous attacks in Pakistan including the assassination of Benazir Bhutto which he and others have denied. Disagreement exists over the exact date of the militant's death.
Context: On the night of 5 August 2009, while he was staying with his second wife at his father-in-law's house in Zangara, a U.S. drone attacked the premises. According to former CIA director Leon Panetta, he was observed on the roof of the house and identified by the distinctive hat he wore. According to The Times, it may have been his desire to father a son that ultimately led to his demise.  Two of his followers, Maulana Meraj and Hakimullah Mehsud, denied the report the following day, dismissing it as "rumors" intended to negatively impact the Taliban's spread of jihad. They suggested that Baitullah had gone into hiding and isolation as a part of a strategy. Hakimullah added that meetings of Taliban officials in Dir and surroundings are proceeding as usual "to make worth of their abilities and to discuss other plans which he called 'war game plans'." These reports were followed by several telephone conversations between AP reporters with Qari Hussain, Maulvi Omar and Hakimullah Mehsud to deny Baitullah's death and to claim he had been ill, perhaps gravely, for several months or had been "busy on the battlefield." Hakimullah indicated that soon a videotape would be released as a proof of his statements.  After his capture on 18 August, Maulvi Omar retracted his previous statements and confirmed that Baitullah had indeed perished in the missile strike. On 20 August, U.S. President Barack Obama stated "We took out [Baitullah] Mehsud" in a radio address. On 25 August, both Hakimullah Mehsud and Wali-ur-Rehman confirmed to BBC and AP correspondents that Baitullah had indeed perished on 23 August from injuries sustained in the missile strike.  The attack is part of the U.S. Central Intelligence Agency's (CIA) campaign using unmanned aerial vehicles in the region by the agency's Special Activities Division. U.S. missile strikes targeting Mehsud territory in South Waziristan became more common after June 2009 when Pakistan, while having been publicly critical of the missile strikes, declared a military offensive against Mehsud.
Question: What else was significant about the time of his death
Answer:
The attack is part of the U.S. Central Intelligence Agency's (CIA) campaign using unmanned aerial vehicles in the region by the agency's Special Activities Division.
