Zu Chongzhi once calculated that the time for the moon to orbit the earth once is 27.2 1223 days, which is almost the same as the modern recognized time of 27.438+0.222 days. One of the many craters on the moon is named "Zu Chongzhi". Zu Chongzhi once calculated that pi should be between 3. 14 15926 and 3. 14 15927.
Zu Chongzhi's name is also listed in the "Discovery Palace" Science Museum, which is tied with the pi value he discovered. On the gallery wall of the auditorium of Moscow State University, there are portraits of famous scientists from all over the world inlaid with colored marble, as well as Zu Chongzhi and Li Shizhen of China.
2. Hua
Hua (1910.1.12-1985.6.12), Han nationality, originally from Jintan, Jiangsu, and originally from Danyang, Jiangsu. World famous mathematician, academician of China Academy of Sciences, foreign academician of American National Academy of Sciences, academician of Third World Academy of Sciences, academician of Bavarian Academy of Sciences of the Federal Republic of Germany. Member of the 1st-6th the NPC Standing Committee of China.
He is the founder and pioneer of China's Analytic Number Theory, Matrix Geometry, Gauge Group, Automorphism Function Theory and Multivariate Complex Function Theory. He is also one of China's most influential mathematicians in the world and is listed as one of the 88 great mathematicians in Chicago Science and Technology Museum. The international achievements in mathematical research include Fahrenheit theorem, Fahrenheit inequality and Hua Wang method.
3. Johann Carl Friedrich Gauss
1April 30, 777-1February 23, 855, at the age of 77, was a famous German mathematician, physicist, astronomer, geographer and one of the founders of modern mathematics. Gauss is regarded as one of the most important mathematicians in history and is known as the "prince of mathematics".
Gauss ranks alongside Archimedes, Newton and Euler as the four greatest mathematicians in the world. He made great achievements in his life, with 1 10 achievements named after his name "Gauss", which is the highest among mathematicians. He made contributions to number theory, algebra, statistics, analysis, differential geometry, geodesy, geophysics, mechanics, electrostatics, astronomy, matrix theory and optics.
4. Archimedes
From 287 BC to 2 12 BC, the great ancient Greek philosopher, encyclopedic scientist, mathematician, physicist and mechanic, the founder of static mechanics and hydrostatics, enjoyed the reputation of "the father of mechanics". Archimedes, Gauss and Newton are listed as the three greatest mathematicians in the world. Archimedes once said, "Give me a fulcrum and I can pry up the whole earth."
Archimedes established the basic principles of statics and hydrostatics. Several methods for finding the center of gravity of geometric figures are given, including the center of gravity of the figure surrounded by parabola and its parallel chords. Archimedes proved that the buoyancy of an object in a liquid is equal to the weight of the liquid it displaces. This result was later called Archimedes principle. He also gave the criterion of equilibrium stability of a parabola rotating body floating in liquid.
5. rene descartes
1596 was born in Dulan (now Descartes, named after Descartes) on March 3/0, and died in Stockholm, Sweden on February1/0. He is a world-famous French philosopher, mathematician and physicist. He made an important contribution to the development of modern mathematics, and was known as the father of analytic geometry because he formulated the geometric coordinate system.
He is also the founder of modern western philosophy and the pioneer of modern materialism, and put forward the idea of "universal doubt". Hegel called him "the father of modern philosophy". His philosophical thoughts deeply influenced later Europeans and opened up the so-called "European rationalism" philosophy. He is one of the most influential masters in European philosophy and science in the17th century, and is known as the "ancestor of modern science".
