Diyelim ki, Ekvator uzunlu\u011fu E=40bin kilometre ve tam da ayn\u0131 uzunlukta bir halat\u0131m\u0131z var. Bu durumda halat\u0131m\u0131z\u0131n u\u00e7lar\u0131 bir birine ancak de\u011fmektedir. (K\u00fcresel D\u00fcnya\u2019da kutuptan kutuba ge\u00e7en bir \u00e7emberin uzunlu\u011fu da Ekvatorunki kadar olacakt\u0131r.) \u015eimdi diyelim ki, bu halat\u0131 Yer\u2019in her noktas\u0131ndan bir metre kadar y\u00fckseltmek istiyoruz.

\nYan\u0131t kolay; sadece 6,28 metre (=2\u03c0). Ama sanki \u00e7ok daha uzun bir ekleme yap\u0131lmas\u0131 gerekliymi\u015f san\u0131labilir hesap yapmazdan \u00f6nce. Bunun nedeni, 6,28 metrenin biz insanlar i\u00e7in \u00f6nemli ama D\u00fcnya i\u00e7in ihmal edilebilir bir uzunluk olmas\u0131d\u0131r.
