- Gottfried Wilhelm Leibniz (1 July 1646 [O.S. 21 June] – 14 November 1716) was a German polymath active as a mathematician, philosopher, scientist and diplomat who invented calculus in addition to many other branches of mathematics and statistics. Leibniz has been called the “last universal genius” due to his knowledge and skills in different fields and because such people became less common during the Industrial Revolution and spread of specialized labor after his lifetime. He is a prominent figure in both the history of philosophy and the history of mathematics. He wrote works on philosophy, theology, ethics, politics, law, history, philology, games, music, and other studies. Leibniz also made major contributions to physics and technology, and anticipated notions that surfaced much later in probability theory, biology, medicine, geology, psychology, linguistics and computer science. In addition, he contributed to the field of library science by devising a cataloguing system whilst working at the Herzog August Library in Wolfenbüttel, Germany, that would have served as a guide for many of Europe’s largest libraries. Leibniz’s contributions to a wide range of subjects were scattered in various learned journals, in tens of thousands of letters and in unpublished manuscripts. He wrote in several languages, primarily in Latin, French and German.

Libya, officially the State of Libya, is a country in the Maghreb region of North Africa. Libya borders the Mediterranean Sea to the north, Egypt to the east, Sudan to the southeast, Chad to the south, Niger to the southwest, Algeria to the west, and Tunisia to the northwest, as well as maritime borders with Greece, Italy and Malta to the north. Libya comprises three historical regions: Tripolitania, Fezzan, and Cyrenaica. With an area of almost 1.8 million km2 (700,000 sq mi), it is the fourth-largest country in Africa and the Arab world, and the 16th-largest in the world. Libya claims 32,000 square kilometers of southeastern Algeria, south of the Libyan town of Ghat. The country’s official religion is Islam, with 96.6% of the Libyan population being Sunni Muslims. The official language of Libya is Arabic, with vernacular Libyan Arabic being spoken most widely. The majority of Libya’s population is Arab. The largest city and capital, Tripoli, is located in northwestern Libya and contains over a million of Libya’s seven million people.
