Question: 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.

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.

Using a quote from the above article, answer the following question: What is the Richardson effect?
HHHHHH
Answer: 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.


Question: The Electric Light Orchestra (ELO) are an English rock band formed in Birmingham in 1970, by songwriters/multi-instrumentalists Jeff Lynne and Roy Wood with drummer Bev Bevan. Their music is characterised by a fusion of Beatlesque pop, classical arrangements, and futuristic iconography. After Wood's departure in 1972, Lynne became the band's leader, arranging and producing every album while writing virtually all of their original material. For their initial tenure, Lynne, Bevan and keyboardist Richard Tandy were the group's only consistent members.

The success of the Children in Need was followed by much support from BBC Radio 2's DJ Chris Evans, who asked his listeners if they wanted ELO to perform. The 50,000 tickets for the resulting BBC Radio 2's "Festival in a Day" in Hyde Park on 14 September 2014 sold out in 15 minutes. Billed as "Jeff Lynne's ELO", Lynne and Tandy were backed by the Take That/Gary Barlow band from the Children in Need concert, led by Mike Stevens  and the BBC Concert Orchestra. The moniker came out from Lynne as a response to ELO tribute and imitation bands, (ELO Part II, the Orchestra, OrKestra and the Music of ELO) who repeatedly used ELO for promoting their own tours. Chereene Allen was the lead violinist for the band. The development of modern digital processing added a smoother finish to the work, which led Lynne to reconsider his preference for studio work, hinting at a UK tour in 2015.  On 8 February 2015, Jeff Lynne's ELO played at the Grammy Awards for the first time. They performed a medley of "Evil Woman" and "Mr. Blue Sky" with Ed Sheeran, who introduced them as "A man and a band who I love".  On 10 September 2015, it was announced that a new ELO album would be released. The album was to be under the moniker of Jeff Lynne's ELO, with the band signed to Columbia Records. Alone in the Universe was released on 13 November 2015. The album was ELO's first album of new material in nearly 15 years. The first track, and single, "When I Was a Boy" was made available for streaming on the same day and a music video for the song was also released. A small promotional tour followed the album's release which saw ELO perform a full concert for BBC Radio 2 along with ELO's first two shows in the United States in 30 years, both which sold out very quickly. ELO also made rare US television appearances on The Tonight Show Starring Jimmy Fallon, Jimmy Kimmel Live and CBS This Morning. Lynne was joined by Traveling Wilbury's photographer Nick J (NJ Latham) for a 19-date European tour that was announced for 2016, with the band playing the Pyramid Stage at Glastonbury Festival on 26 June 2016.  In 2017 they played their "Alone in the Universe" tour. In 2017 they played at the Rock and Roll Hall of Fame during the 32nd Annual Induction Ceremony.

Using a quote from the above article, answer the following question: What were they doing at this time?
