What is Pi Day? The story of why some celebrate March 14 – and others say it’s a ‘powerful conspiracy’
From: The Independent
14 March is celebrated by some as the most exciting day in mathematics – when the date lines up in the numbers of the famous constant, Pi or π. But some people would rather it isn’t celebrated at all.
The day looks like 3.14 for those that write dates in the month then day format, but that is rarely used outside of the Americas.
Many people instead opt to celebrate the potentially more interesting Pi approximation day, which takes place on 22 July or 22/7 – a way of working out an approximate value for Pi for use in rough calculations.
And still others would rather that Pi day was not celebrated at all, and say that the number should not be treated with such reverence. Instead, they say that we should use Tau – a number that serves much the same purpose and can be celebrated on 28 June, or 6/28 in America.
The complaints about the date are relatively obvious. Most places around the world use a different system to the US, where Pi Day was born.
By far the most popular date format is day/month/year, as is used in the UK as well as much of Asia, Australia, Africa and South America. It is not possible to write Pi day using that format, but it is easy to write Pi approximation day.
In China and many other countries in south-east Asia, dates are written year/month/day. It is possible to do Pi day in that format since the day (14) does follow the month (3), but the year comes first and throws that off slightly.
But the complaints about the competitor to Pi Day, Tau Day, are much more aggressive – and campaigners for the change have made a website and a full manifesto, laying out exactly why the world is wrong.
That manifesto, written by Tau fan Michael Hartl, is dedicated to the “true circle constant”, which he says should be referred to by the Greek letter Tau.
The number itself is simply Pi, but doubled – 6.28318, and so on. That makes it easier to use in many applications, campaigners claim.
But those behind the Tau manifesto admit that they are facing a difficult challenge: “a powerful conspiracy, centuries old, determined to propagate pro-Pi propaganda”.
But they hope that they can prove that Pi “is a confusing and unnatural choice for the circle constant”, they say, even if the name of the constant and its day doesn’t actually change.
To settle the argument, some people have taken to celebrating a specific “Tau time” on Pi day – 6.28pm. That is when, for instance, the Massachusetts Institute of Technology sends out its admissions decisions over the internet, which was a change made to welcome Tau into the celebrations.

What is Pi Day? The story of why some celebrate March 14 – and others say it’s a ‘powerful conspiracy’
From: The Independent
14 March is celebrated by some as the most exciting day in mathematics – when the date lines up in the numbers of the famous constant, Pi or π. But some people would rather it isn’t celebrated at all.
3月14日被一些人视为数学界最激动人心的日子——这一天的日期与著名常数π相吻合。然而，也有人认为，这个日子其实没有庆祝的必要。
constant
constant /ˈkɒn.stənt/ 作名词，熟词僻义，表示“常数；常量；恒量”，英文解释为“a number or quantity that does not vary”。
补充：
📍variable表示“可变情况；变量；可变因素”（a situation, number or quantity that can vary or be varied）。
作形容词，constant 表示“恒久不变的；稳定的”，英文解释为“staying the same, or not getting less or more”举个🌰：We ran at a fairly constant speed. 我们保持了比较平稳的跑动速度。
The day looks like 3.14 for those that write dates in the month then day format, but that is rarely used outside of the Americas.
对于那些用“先月后日”格式书写日期的人来说，这一天似乎正好为3.14，但这种格式在美洲以外的地区并不常见。
format
format /ˈfɔː.mæt/ 作名词，1）表示“格式”，英文解释为“the way in which data is stored or held to be worked on by a computer”；
2）表示“总体安排；计划；设计”，英文解释为“the general arrangement, plan, design, etc. of sth”举个🌰：The format of the new quiz show has proved popular. 新的智力竞赛节目的总体安排结果证明很受欢迎。
作动词，3）表示“（尤指在计算机上）安排…的版式”，英文解释为“to organize or arrange text, especially on a computer, according to a chosen pattern”
Many people instead opt to celebrate the potentially more interesting Pi approximation day, which takes place on 22 July or 22/7 – a way of working out an approximate value for Pi for use in rough calculations.
因此，很多人转而选择庆祝可能更有趣的圆周率近似日，即7月22日或22/7——一种计算圆周率近似值的方法，用于粗略估算。
opt
opt /ɒpt/ 表示“选择，挑选；（尤指）优先选择”，英文解释为“to make a choice, especially of one thing or possibility instead of others”举个🌰：Depending on your circumstances you can opt for one method or the other. 根据自己的情况，你可以选择这种或那种方法。
approximation
approximation /əˌprɒk.sɪˈmeɪ.ʃən/ 1）表示“近似值”，英文解释为“An approximation is a number, calculation, or position that is close to a correct number, time, or position, but is not exact.”举个🌰：As we know, 3.14159 is only an approximation. 如我们所知，3.14159只是一个近似值。
2）表示“近似物”，英文解释为“An approximation is a fact, object, or description which is similar to something else, but which is not exactly the same.”举个🌰：That is a fair approximation of the way in which the next boss is being chosen. 那是一个挑选下任老板的大体近似方式。
And still others would rather that Pi day was not celebrated at all, and say that the number should not be treated with such reverence. Instead, they say that we should use Tau – a number that serves much the same purpose and can be celebrated on 28 June, or 6/28 in America.
还有些人根本就反对庆祝圆周率日，他们认为这个数字不应受到过分推崇。相反，他们认为我们应该使用Tau（希腊字母τ）——一个具有相同作用的数字，可以在6月28日（美国日期格式6/28）庆祝。
reverence
reverence /ˈrev.ər.əns/ 表示“尊敬；崇敬”，英文解释为“a feeling of respect or admiration for someone or something”举个🌰：She has/shows/feels great reverence for her professors. 她对教她的那些教授们很崇敬。
The complaints about the date are relatively obvious. Most places around the world use a different system to the US, where Pi Day was born.
对圆周率日日期的争议其实是显而易见的。世界上大多数地方都使用与美国不同的日期格式，而圆周率日正诞生于美国。
By far the most popular date format is day/month/year, as is used in the UK as well as much of Asia, Australia, Africa and South America. It is not possible to write Pi day using that format, but it is easy to write Pi approximation day.
到目前为止，最流行的日期格式是日/月/年，英国以及亚洲、澳大利亚、非洲和南美洲的大部分地区都使用这种格式。在这种格式下，无法表示圆周率日，而表示圆周率近似日却很容易。
In China and many other countries in south-east Asia, dates are written year/month/day. It is possible to do Pi day in that format since the day (14) does follow the month (3), but the year comes first and throws that off slightly.
在中国和东南亚的许多国家，日期的写法是年/月/日。用这种格式来表示圆周率日是可行的，因为日（14）确实在月（3）之后，但年在前，略显不协调。
throw sth off
throw sth/someone off 1）表示“摆脱，甩掉”，英文解释为“to escape from something or someone following you”举个🌰：He managed to throw off his pursuers. 他设法摆脱了追捕他的人。
2）表示“发出或排放”，英文解释为“To emit or discharge”举个🌰：The chemical plant throws off toxic waste. 那家化工厂排出有毒废物。
3）表示“分散注意力或转移”，英文解释为“To distract or divert”举个🌰：The magician threw off the audience with a surprise trick. 魔术师用一个令人吃惊的戏法迷惑了观众。
3）表示“快速或不费力地产出”，英文解释为“To produce quickly or without effort”举个🌰：She can throw off an essay in just a couple of hours. 她能在短短几个小时内写出一篇文章。
此处throw that off 可以理解为“使某事偏离预期的状态或轨迹”，“使其偏离正轨”或“使其出现偏差”。
But the complaints about the competitor to Pi Day, Tau Day, are much more aggressive – and campaigners for the change have made a website and a full manifesto, laying out exactly why the world is wrong.
但是，支持τ日替代π日的人们，其不满表现得更加激烈——他们建立了网站，发表了完整的宣言，明确阐述了当前做法的错误所在。
aggressive
aggressive /əˈɡres.ɪv/ 1）表示“好斗的；挑衅的；侵略的”，英文解释为“angry, and behaving in a threatening way; ready to attack”；
2）表示“气势汹汹的；声势浩大的；志在必得的；积极进取的；有冲劲的；雄心勃勃的”英文解释为“acting with force and determination in order to succeed”如：an aggressive advertising campaign 一场声势浩大的广告宣传活动。
campaigner
campaigner /ˌkæmˈpeɪ.nər/ 表示“运动参加者；运动倡导者；活动家”，英文解释为“a person who takes part in organized activities that are intended to change something in society”如：an animal rights campaigner 动物权利运动的支持者。
manifesto
manifesto /ˌmæn.ɪˈfes.təʊ/ 表示“（尤指政党的）宣言”，英文解释为“a written statement of the beliefs, aims, and policies of an organization, especially a political party”
That manifesto, written by Tau fan Michael Hartl, is dedicated to the “true circle constant”, which he says should be referred to by the Greek letter Tau.
该宣言由τ日支持者迈克尔·哈特尔 (Michael Hartl) 撰写，旨在纪念“真正的圆常数”，他认为这个常数应当用希腊字母τ表示。
The number itself is simply Pi, but doubled – 6.28318, and so on. That makes it easier to use in many applications, campaigners claim.
τ这个数字本身就是圆周率，只是翻倍了——6.28318。支持者声称，这样使得它在许多应用场景中更为方便。
But those behind the Tau manifesto admit that they are facing a difficult challenge: “a powerful conspiracy, centuries old, determined to propagate pro-Pi propaganda”.
但τ宣言的幕后推手承认，他们正面临着一个艰巨的挑战：“一个长达几个世纪的强大阴谋，坚定地传播π的理念”。
conspiracy
conspiracy /kənˈspɪr.ə.si/ 表示“合谋；密谋策划；阴谋”，英文解释为“Conspiracy is secret planning by a group of people to do something illegal.”举个🌰：Seven men, all from France, admitted conspiracy to commit arson. 全都来自于法国的七名男子承认了合谋纵火。
📍conspiracy theories 阴谋论。
propagate
propagate /ˈprɒpəˌɡeɪt/ 表示“传播，散播；宣传”，英文解释为“to spread opinions, lies, or beliefs among a lot of people”举个🌰：Such lies are propagated in the media. 这样的谎言通过媒体传播开来。
propaganda
propaganda /ˌprɑː.pəˈɡæn.də/ 表示“宣传；鼓吹”，英文解释为“information, ideas, opinions, or images, often only giving one part of an argument, that are broadcast, published, or in some other way spread with the intention of influencing people's opinions”
But they hope that they can prove that Pi “is a confusing and unnatural choice for the circle constant”, they say, even if the name of the constant and its day doesn’t actually change.
但他们希望他们能够证明π“对于圆常数来说是一个令人困惑且不自然的选择”，他们说，即使这个常数的名称和日期实际上并没有改变。
To settle the argument, some people have taken to celebrating a specific “Tau time” on Pi day – 6.28pm. That is when, for instance, the Massachusetts Institute of Technology sends out its admissions decisions over the internet, which was a change made to welcome Tau into the celebrations.
为了解决这一争论，一些人开始在π日庆祝特定的τ时刻6:28。例如，麻省理工学院就是在这一时间点通过互联网发布其录取通知的，这是为了欢迎将τ纳入庆祝活动而做出的改变。
