IN: Eratosthenes of Cyrene (; Greek: Eratosthenes o Kurenaios, IPA:

Eratosthenes now continued from his knowledge about the Earth. Using his discoveries and knowledge of its size and shape, he began to sketch it. In the Library of Alexandria he had access to various travel books, which contained various items of information and representations of the world that needed to be pieced together in some organized format. In his three-volume work Geography (Greek: [Geographika] ), he described and mapped his entire known world, even dividing the Earth into five climate zones: two freezing zones around the poles, two temperate zones, and a zone encompassing the equator and the tropics. He had invented geography. He created terminology that is still used today. He placed grids of overlapping lines over the surface of the Earth. He used parallels and meridians to link together every place in the world. It was now possible to estimate one's distance from remote locations with this network over the surface of the Earth. In the Geography the names of over 400 cities and their locations were shown: this had never been achieved before. Unfortunately, his Geography has been lost to history, but fragments of the work can be pieced together from other great historians like Pliny, Polybius, Strabo, and Marcianus. The first book was something of an introduction and gave a review of his predecessors, recognizing their contributions that he compiled in the library. In this book Eratosthenes denounced Homer as not providing any insight into what he now described as geography. His disapproval of Homer's topography angered many who believed the world depicted in the Odyssey to be legitimate. He also commented on the ideas of the nature and origin of the Earth: he had thought of Earth as an immovable globe; while on its surface was a place that was changing. He had hypothesized that at one time the Mediterranean was a vast lake that covered the countries that surrounded it; and had only become connected to the ocean to the west when a passage had opened up sometime in its history. In the second book is his discovery about the circumference of the Earth. This is where, according to Pliny, "The world was grasped." Eratosthenes described his famous story of the well in Syene, described above. This book would now be considered a text on mathematical geography. His third book of the Geography contained political geography. He cited countries and used parallel lines to divide the map into sections, to give accurate descriptions of the realms. This was a breakthrough, and can be considered the beginning of geography.

IN: Charlton is related to several professional footballers on his mother's side of the family: his uncles were Jack Milburn (Leeds United and Bradford City), George Milburn (Leeds United and Chesterfield), Jim Milburn (Leeds United and Bradford City) and Stan Milburn (Chesterfield, Leicester City and Rochdale), and legendary Newcastle United and England footballer Jackie Milburn, was his mother's cousin. However, Charlton credits much of the early development of his career to his grandfather Tanner and his mother Cissie. His elder brother, Jack, initially worked as a miner before applying to the police, only to also become a professional footballer with Leeds United. His other brother, Tommy, plays walking football for the Mature Millers club in Rotherham.

On 9 February 1953, then a Bedlington Grammar School pupil, Charlton was spotted playing for East Northumberland schools by Manchester United chief scout Joe Armstrong. Charlton went on to play for England Schoolboys and the 15-year-old signed with United on 1 January 1953, along with Wilf McGuinness, also aged 15. Initially his mother was reluctant to let him commit to an insecure football career, so he began an apprenticeship as an electrical engineer; however, he went on to turn professional in October 1954. Charlton became one of the famed Busby Babes, the collection of talented footballers who emerged through the system at Old Trafford in the 1940s, 1950s and 1960s as Matt Busby set about a long-term plan of rebuilding the club after the Second World War. He worked his way through the pecking order of teams, scoring regularly for the youth and reserve sides before he was handed his first team debut against Charlton Athletic in October 1956. At the same time, he was doing his National service with the Royal Army Ordnance Corps in Shrewsbury, where Busby had advised him to apply as it meant he could still play for Manchester United at the weekend. Also doing his army service in Shrewsbury at the same time was his United teammate Duncan Edwards. Charlton played 14 times for United in that first season, scoring twice on his debut and managing a total of 12 goals in all competitions, and including a hat-trick in a 5-1 away win over Charlton Athletic in the February. United won the league championship but were denied the 20th century's first "double" when they controversially lost the 1957 FA Cup Final to Aston Villa. Charlton, still only 19, was selected for the game, which saw United goalkeeper Ray Wood carried off with a broken cheekbone after a clash with Villa centre forward Peter McParland. Though Charlton was a candidate to go in goal to replace Wood (in the days before substitutes, and certainly before goalkeeping substitutes), it was teammate Jackie Blanchflower who ended up between the posts. Charlton was an established player by the time the next season was fully underway, which saw United, as current League champions, become the first English team to compete in the European Cup. Previously, the Football Association had scorned the competition, but United made progress, reaching the semi-finals where they lost to holders Real Madrid. Their reputation was further enhanced the next season as they reached the quarter finals to play Red Star Belgrade. In the first leg at home, United won 2-1. The return in Yugoslavia saw Charlton score twice as United stormed 3-0 ahead, although the hosts came back to earn a 3-3 draw. However, United maintained their aggregate lead to reach the last four and were in jubilant mood as they left to catch their flight home, thinking of an important League game against Wolves at the weekend.
