Holidays Related to Numbers 與數字有關的節日

In recent years， mathematicians and scientists have begun campaigns to mark certain dates in celebration of significant principles and here are a few to add to your calendar.

近年來，數學家和科學家為某些特定日期發起一些活動以慶祝那些有重大意義的定律。這里有一些可以添加到你的日歷中。

Mole Day 摩爾日

Mole Day is celebrated annually on Oct. 23 from 6：02 am to 6：02 pm. It remembers Avogadro's Constant （6.02×1023）， which is a basic measuring unit in chemistry. A mole of any substance contains Avogadro's number of elementary particles.

The concept of the celebratory day was created by Maurice Oehler， a retired high school chemistry teacher from Wisconsin， the US. The Mole Day was created in 1991 and has been honored every year since then. Each Mole Day has a specific theme. People hope to use the day to develop interest in chemistry， encouraging schools around the globe to celebrate Mole Day with various activities related to chemistry

摩爾日的慶祝通常是在10月23日的上午6：02到下午6：02，以紀念阿伏伽德羅常量（6.02×1023）。阿伏伽德羅常量是化學中的一個基本測量單位。每一摩爾任何物質含有阿伏伽德羅常量個微粒。

慶祝這一節日的想法由莫里斯·奧勒爾提出，他是來自美國威斯康星州的一位退休高中化學老師。摩爾日創立于 1991年，此后每年都予以慶祝。每一屆摩爾日都有不同的主題。通過鼓勵世界各地的學校開展各種與化學相關的活動來慶祝摩爾日，人們希望用這一天來培養人們對化學的興趣。

Square Root Day 平方根日

Square Root Day is a holiday that heartily honors those dates where the combination of day and month and year forms square roots： e.g. 2/2/2004 and 3/3/2009. The last Square Root Day was 4/4/2016 and the next one will be 5/5/2025.

The holiday was created by a high school teacher Ron Gordon in California， the US. Square Root Day now has its own website where celebrants can gather.

平方根日，就是日、月均為年份最后兩位數構成的數字的平方根，比如：2004年2月2日，2009年3 月3日。上一次的平方根日是2016年 4月4日，下一次的平方根日將在 2025年5月5日。

平方根日由美國加利福尼亞州的高中老師羅恩·戈登創立。現在它有自己的網站，人們可以在那里慶祝。

Fibonacci Day 斐波那契日

November 23 is Fibonacci Day， an annual holiday that honors one of the most influential mathematicians of the Middle Ages—Leonardo Fibonacci.

The Fibonacci sequence， also known as the rabbit sequence， the golden section sequence， refers to a sequence such as： 1，1， 2， 3， 5， 8，13， 21... In this sequence， the value of each number is equal to the sum of its two preceding numbers. It was discovered by Fibonacci in Pisa， Italy， and has direct applications in modern physics， quasicrystal structure， chemistry and other fields.

11月23日是斐波那契紀念日，該節日每年舉行，以紀念中世紀最有影響力的數學家之一列昂納多·斐波那契。

斐波那契數列，又稱兔子數列，黃金分割數列，指的是這樣一個數列：1，1，2，3，5，8，13，21…。在這個數列中，每一個數字的值都等于它前面兩個數字的和。該數列是由意大利比薩市的斐波那契發現的，在現代物理、準晶體結構、化學等領域，斐波那契數列都有直接的應用。

Pi Day 圓周率日

As a significant day for “math-man”， March 14th is the day that can't be missed. It is identified as the International Pi Day. The earliest known large-scale Pi-themed celebration was organized by Larry Shaw， a physicist on March 14th， 1988， at the San Francisco Science Museum.

On March 12th， 2009， the US House of Representatives passed a resolution declaring March 14th as National Pi Day.

作為“數學人”的重大節日，3月14日不可錯過，是一年一度的國際圓周率日。已知最早的大型的以圓周率為主題的慶祝活動是由物理學家拉里·肖于1988年3月14日組織，在舊金山科學博物館舉行。

2009年3月12日，美國眾議院通過一項決議，聲明3月14日是全國圓周率日。
