As proved by Archimedes, the area enclosed by a circle is $\pi$ multiplied by the radius squared \(\pi r^2\). Apollonius of Perga showed that a circle may also be defined as the set of points in a plane having a constant ratio (other than 1) of distances to two fixed foci, A and B.
Early science, particularly geometry and astrology and astronomy, was connected to the divine for most medieval scholars, and many believed that there was something intrinsically \textit{divine} or \textit{perfect} that could be found in circles. Some people still believe that the earth is still flat and is circular.
Some highlights in the history of the circle are:
\begin{enumerate}
\item 1700 BC -- The Rhind papyrus gives a method to find the area of a circular field. The result corresponds to \(\frac{256}{81}\) (3.16049\dots) as an approximate value of $\pi$.
\item 300 BC -- Book 3 of Euclid's Elements deals with the properties of circles.
In Plato's Seventh Letter there is a detailed definition and explanation of the circle. Plato explains the perfect circle, and how it is different from any drawing, words, definition or explanation.
\item 1880 -- Lindemann proves that $\pi$ is transcendental, effectively settling the millennia-old problem of squaring the circle
\item 1978 -- Donald Knuth develops \TeX\ in order to enable future generations to typeset Mathematics in a beautiful way, including all the equations that one can associate with circles.
\end{enumerate}

AdobeReader 提供大约 15 种不同的语言版本。这是您新年愿望的可能翻译数量。可以使用 JavaScript 对象访问打开 PDF 的阅读器的语言版本app.language。请参阅：
它可用于选择匹配的问候语。我为法语和德语以及一些默认语言（根据说话者的数量）选择了该问候语。但是，可能需要安装额外的字体包 ;-) ：

HappyNewYear()只需用以下代码替换函数的定义：
function HappyNewYear()
{
switch(app.lang){
case "FRA":
hny="Bonne Ann"+String.fromCharCode(233)+"e !";break;;
case "DE":
hny="Gl"+String.fromCharCode(252)+"ckliches Neues Jahr!";break;;
default:
hny=String.fromCharCode(26032,24180,24555,20048)+"!";
}
app.alert(hny,3);
}
请注意，一些非 ASCII 字符必须用其 Unicode 表示形式替换。
