Question: Carr was born Joseph Francis Karr on October 23, 1879, at his parents' home in the Irish neighborhood on the East End of Columbus, Ohio. His father, Michael Karr, was a shoemaker who was born in Ireland in 1841 and immigrated to the United States in 1864. His mother Margaret Karr was born in New York to Irish immigrant parents. Carr had five older siblings, Bridget, James, John, Mary, and Michael, and a younger brother, Edward.

In 1900, Carr organized a baseball team made up of employees of the railroad's Panhandle Division. The team, known as the Famous Panhandle White Sox, played in the Capital City League and the Saturday Afternoon League in Columbus for several years. According to the Chicago Tribune, Carr's Panhandle club "gained a reputation in semi-professional ranks throughout the country." In 1907, Carr began a long association with the sport of football. He obtained permission from the Panhandle Athletic Club to reorganize the Columbus Panhandles football team, a team that had been formed in 1900 or 1901 and disbanded in 1904. He secured players from the railroad shop where he worked. The core of Carr's Panhandles teams were six Nesser brothers who worked at the shop and were excellent athletes. To save on expenses, the players, who were railroad employees, used their passes to ride the train for free and practiced during the lunch hour on the railroad yards. Over the next 13 years, the Panhandles became known as a traveling team, as Carr saved money on travel expenses and stadium rental by playing mostly road games. In 1921, the Fort Wayne Journal called the Panhandles the "most renowned professional football aggregation in the country." Carr also continued his association with professional baseball while running the Panhandles, serving for several years as the secretary/treasurer and later president of the Ohio State League, a minor league baseball circuit. As early as 1917, Carr was one of the leading advocates of a plan to develop a national professional football league. Sources are not in agreement as to what role, if any, he played in the formation of the American Professional Football Association (APFA), which later became the National Football League (NFL). However, once the APFA was formed in 1920, Carr's Panhandles played in the league's inaugural season. The 1920 Panhandles team played only one home game and compiled a 2-7-2 record.

Using a quote from the above article, answer the following question: What is the significance of Columbus Panhandles?
HHHHHH
Answer: the Columbus Panhandles football team, a team that had been formed in 1900 or 1901 and disbanded in 1904.

Question: 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.
