一些有趣的联系！
Some Interesting Connections!
摘要：
数学之美的一个来源是两个根本不同的对象之间完全出乎意料的联系。例如，一个真正的单摆的时间周期与一个函数联系在一起，这个函数是由求一个正整数分解为两个平方和的方法的数目而产生的，这难道不令人惊讶吗？为什么计数的内在属性和相互关系应该出现在支配单摆运动的自然定律中？在这篇文章中，我们将看到一些来自组合学，数论和物理学的令人惊讶和美丽的结果。
英文摘要：
One source of beauty in mathematics is totally unexpected connections between two fundamentally different objects. For instance, is it not surprising that the time period of a real simple pendulum is linked with a function arising out of finding the number of ways in which a positive integer could be decomposed as a sum of two squares? Why should inherent properties and interrelations among counting numbers should appear in the laws of nature that govern the motion of a simple pendulum? In this article we will see some such surprising and beautiful results coming from combinatorics, number theory and physics.
