Presentation Transcript

  1. Leonardo Fibonacci • Born: 1170 in Pisa, Italy • Died: 1240

  2. Fibonacci: • The sequence of numbers 0,1,1,2,3,5,8,13,21,… , formed by adding consecutive numbers is named after him – The Fibonacci Sequence • Wrote on mathematical topics such as number theory, practical problems of business mathematics, and surveying, algebra and recreational mathematics. • Was one of the first to pose story problems which became classic mental challenges

  3. Leonardo da Pisa • Born in Pisa, Italy. At the time it was a flourishing commercial city . There he would learn the basics of business calculation • Moved to Algeria when he was 20 to learn Indian numerals and Arabic methods. His father, Guilielmo, held a diplomatic post in the city of Bugia. His father intended for Leonardo to become a merchant but instead he became one of the most famous mathematicians of all time.

  4. A widely known traveler, Fibonacci, used his opportunity to learn various mathematical techniques from various regions.

  5. Fibonacci’s Bigollo – A Traveller • Received a “free” North African education. • Deduced many of his thoughts and ideas from the area’s centers of trade. • Learned Hindu-Arabic mathematics from many of his scholars of the time. • Extend on the work of Greek mathematicians Euclid and Diophantus.

  6. “Lucky Son” • Created the Fibonacci Sequence • Was one of the first people to introduce the Hindu-Arabic Number System – the system we use today. - It is based on ten digits with the decimal point and a symbol for zero. • His book, Liber abbaci (The Book of Calculating), persuaded many Europeans to use this new mathematical system.

  7. Fibonacci Sequence and Rabbits? • Fibonacci’s Sequence was discovered after an investigation of the reproduction of rabbits. • He found that rabbits produced pairs of rabbits that followed the Fibonacci Sequence.

  8. More with the Fibonacci Sequence • From the Sequence, Fibonacci Rectangles were created.

  9. Even more with the Fibonacci Sequence • The Fibonacci Sequence is used in various art forms. Here a picture of a 14th century Greek building is shown. • Watch how art is created using the Fibonacci Rectangles

  10. Honoring the Mathematician • He was awarded a yearly salary by the Republic of Pisa in 1240, for the importance of his work and and his public service to the city's administration.
