斐波纳契日，数学家和科学家向其中一位伟人致敬的场合：莱昂纳多·博纳奇，俗称斐波纳契。这位中世纪数学家以普及印度教-阿拉伯数字系统而闻名，该系统使用零、小数点和十位数，取代了沉重的罗马数字系统。但是，他最大的认可来自他著名的数字序列：0，1，1，2，3，5，8。把前两个数字相加，你就会得到第三个数字；将前两个数字相加，得到下一个数字，依此类推。除了零之外，序列中的前四个数字与今天的日期一致：23/11。
原文：
Fibonacci Day is an occasion for mathematicians and scientists to pay tribute to one of the great figures: Leonardo Bonucci, commonly known as Fibonacci. This medieval mathematician was known for popularizing the Hindu Arabic numeral system, which replaced the heavy Roman numeral system with zeros, decimal points, and tens. However, his greatest recognition comes from his famous sequence of numbers: 0, 1, 1, 2, 3, 5, 8. Adding the first two numbers gives you the third number; Add the first two numbers together to get the next number, and so on. Except for zero, the first four digits in the sequence match today's date: 23/11.
