The figures of mathematics

• Thales. He is the first figure that found the theorem. He was also found applied knowledge.
  
• Pythagoras. He is the first figure who said that axiom of postulates need to analysed before, if we want to expand the geometry. He was successfull prove the theorem Pythagoras the first and the best.
  
• Eodoxus. He had made the definition about approximate length of irrational number with cross multiplying method.
  
• Archimedes. He could applicate the mathematics. He is interest in pure mathematics : number, geometry, count the wide of geometry shapes.
  
• Diophantus. He had wrote "Arithmetica", it contains of expanding the algebra that he did with make some similarity.
  
• Al Khawarizmi. The great work are at algebra and astronomy. The algebra had been started from definition the principle of number and gave the solutions. Six chapters which he was wrote consist of six kinds similarity included three kinds operation : root, quadrate, and number.
  
• Fibonacci. Expanded the zero number and count the patterns of nature which was unusual, even gave the basic of introducing algebra to Western Countries. He found the row of number that called like his own name : Fibonacci row = 1,1,2,3,5,8,13,21,34,55,89,144,233,377, ...
  
• John Napier. He found the basic concept of logarithm.
  
• Rene Descartes. He was connected algebra ang geometry.
  
• Isaac Newton. The idea of calculus is from him.
  
• Jean Baptiste Joseph Fourier. He studied about trigonometry and theory function of real variable.
