Confucius (Chinese: 孔夫子; Pinyin: Kǒng Fūzǐ; Wade-Giles: K'ung-fu-tzu), lit. "Master Kung,"[1] 551 BCE – 479 BCE) was an esteemed Chinese thinker and social philosopher, whose teachings and philosophy have deeply influenced Chinese, Japanese, Korean, and Vietnamese thought and life. His philosophy emphasized personal and governmental morality, correctness of social relationships, justice and sincerity. These values gained prominence in China over other doctrines, such as Legalism (法家) or Taoism (道家) during the Han Dynasty.[2][3][4] Confucius' thoughts have been developed into a system of philosophy known as Confucianism (儒家). It was introduced to Europe by the Jesuit Matteo Ricci, who was the first to Latinise the name as "Confucius" . His teachings may be found in the Analects of Confucius (論語), a collection of "brief aphoristic fragments", which was compiled many years after his death. Modern historians do not believe that any specific documents can be said to have been written by Confucius,[5][6] but for nearly 2,000 years he was thought to be the editor or author of all the Five Classics[7][8] such as the Classic of Rites (editor), and the Spring and Autumn Annals (春秋) (author).
Nicolas Copernicus (1473-1543) Copernicus is said to be the founder of modern astronomy. He was born in Poland,1 and eventually was sent off to Cracow University, there to study mathematics and optics; at Bologna, canon law. Returning from his studies in Italy, Copernicus, through the influence of his uncle, was appointed as a canon in the cathedral of Frauenburg where he spent a sheltered and academic life for the rest of his days. Because of his clerical position, Copernicus moved in the highest circles of power; but a student he remained. For relaxation Copernicus painted and translated Greek poetry into Latin. His interest in astronomy gradually grew to be one in which he had a primary interest. His investigations were carried on quietly and alone, without help or consultation. He made his celestial observations from a turret situated on the protective wall around the cathedral, observations were made "bare eyeball," so to speak, as a hundred more years were to pass before the invention of the telescope. In 1530, Copernicus completed and gave to the world his great work De Revolutionibus, which asserted that the earth rotated on its axis once daily and traveled around the sun once yearly: a fantastic concept for the times. Up to the time of Copernicus the thinkers of the western world believed in the Ptolemiac theory that the universe was a closed space bounded by a spherical envelope beyond which there was nothing.
Claudius Ptolemy, an Egyptian living in Alexandria, at about 150 A.D., gathered and organized the thoughts of the earlier thinkers. (It is to be noted that one of the ancient Greek astronomers, Aristarchus, did have ideas similar to those more fully developed by Copernicus but they were rejected in favour of the geocentric or earth-centered scheme as was espoused by Aristotle.) Ptolemy's findings were that the earth was a fixed, inert, immovable mass, located at the center of the universe, and all celestial bodies, including the sun and the fixed stars, revolved around it. It was a theory that appealed to human nature. It fit with the casual observations that a person might want to make in the field; and second, it fed man's ego.
Alfred Wegener. The Origins of Continents and Oceans (4th edition) Some truly revolutionary scientific theories may take years or decades to win general acceptance among scientists. This is certainly true of plate tectonics, one of the most important and farranging geological theories of all time; when first proposed, it was ridiculed, but steadily accumulating evidence finally prompted its acceptance, with immense consequences for geology, geophysics, oceanography, and paleontology. And the man who first proposed this theory was a brilliant interdisciplinary scientist, Alfred Wegener. Born on November 1,
1880, Alfred Lothar Wegener earned a Ph.D in astronomy from the University of Berlin in 1904. However, he had always been interested in geophysics, and also became fascinated with the developing fields of meteorology and climatology. During his life, Wegener made several key contributions to meteorology: he pioneered the use of balloons to track air circulation, and wrote a textbook that became standard throughout Germany.
