Answer the question at the end by quoting:

Bradbury was born on August 22, 1920, in Waukegan, Illinois, to Esther (nee Moberg) Bradbury (1888-1966), a Swedish immigrant, and Leonard Spaulding Bradbury (1890-1957), a power and telephone lineman of English descent. He was given the middle name "Douglas" after the actor Douglas Fairbanks. Bradbury was related to the American Shakespeare scholar Douglas Spaulding and descended from Mary Bradbury, who was tried at one of the Salem witch trials in 1692.
Throughout his youth, Bradbury was an avid reader and writer and knew at a young age that he was "going into one of the arts." Bradbury began writing his own stories at age 11 (1931), during the Great Depression -- sometimes writing on the only available paper, butcher paper. In his youth, he spent much time in the Carnegie library in Waukegan, reading such authors as H. G. Wells, Jules Verne, and Edgar Allan Poe. At 12, Bradbury began writing traditional horror stories and said he tried to imitate Poe until he was about 18. In addition to comics, he loved Edgar Rice Burroughs, creator of Tarzan of the Apes, especially Burroughs' John Carter of Mars series. The Warlord of Mars impressed him so much that at the age of 12, he wrote his own sequel. The young Bradbury was also a cartoonist and loved to illustrate. He wrote about Tarzan and drew his own Sunday panels. He listened to the radio show Chandu the Magician, and every night when the show went off the air, he would sit and write the entire script from memory. As a teen in Beverly Hills, he often visited his mentor and friend science-fiction writer Bob Olsen, sharing ideas and maintaining contact. In 1936, at a secondhand bookstore in Hollywood, Bradbury discovered a handbill promoting meetings of the Los Angeles Science Fiction Society. Excited to find there were others sharing his interest, Bradbury joined a weekly Thursday-night conclave at age 16. At age 17, Bradbury read stories published in Astounding Science Fiction, and read everything by Robert A. Heinlein, Arthur C. Clarke, and the early writings of Theodore Sturgeon and A. E. van Vogt. Bradbury cited H. G. Wells and Jules Verne as his primary science-fiction influences. Bradbury identified with Verne, saying, "He believes the human being is in a strange situation in a very strange world, and he believes that we can triumph by behaving morally". Bradbury admitted that he stopped reading science-fiction books in his 20s and embraced a broad field of literature that included Alexander Pope and poet John Donne. Bradbury had just graduated from high school when he met Robert Heinlein, then 31 years old. Bradbury recalled, "He was well known, and he wrote humanistic science fiction, which influenced me to dare to be human instead of mechanical."

How did Jules Verne influence him?

"He believes the human being is in a strange situation in a very strange world, and he believes that we can triumph by behaving morally".

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.

How was he able to achieve this?
He cited countries and used parallel lines to divide the map into sections, to give accurate descriptions of the realms.
