科學的樂趣是什麼呢？是發現自然的奧秘？或與神奇相逢嗎？還是知道控制世界的辦法？…… 也許有人只是好奇真理的模樣哩！說起 W!o+ 的快樂有點與眾不同︰『除錯』。

一時心裡想著 Mrphs 曾經講過的話︰

W!o+ 小時候，許多快樂時光都在『除錯』中度過。他認為即使說『科南‧道爾』當『偵探』，未必然能是個『好偵探』。雖然大家以為他既能創造『大偵探』福爾摩斯，又怎會自己不是的呢？因為一個作者早知道『結局』，掌握所有『線索』，過程常常不過是『故布疑陣』，迷惑讀者而已。這可與『真偵探』的遭遇大不相同，未能『先知』，就不能『神奇』！文章固然膾炙人口，要談深得三昧卻未必然的吧！！所以『寫程式』、『讀程式』、『測程式』 ……者，『錯誤』無論來自『何方』『何時』…… 都是良師益友，都要認真對待。此『不速之客』的『偶然』『錯誤』，往往恰恰是『利涉大川』者之『必然』『所需』。

需：有孚，光亨，貞吉。利涉大川。

彖曰：需，須也﹔險在前也。剛健而不陷，其義不困窮矣。需有孚，光亨，貞吉。位乎天位，以正中也。利涉大川，往有功也。

象曰：云上於天，需﹔君子以飲食宴樂。

初九：需于郊。利用恆，無咎。
象曰：需于郊，不犯難行也。利用恆，無咎﹔未失常也。

九二：需于沙。小有言，終吉。
象曰：需于沙，衍在中也。雖小有言，以終吉也。

九三：需于泥，致寇至。
象曰：需于泥，災在外也。自我致寇，敬慎不敗也。

六四：需于血，出自穴。
象曰：需于血，順以聽也。

九五：需于酒食，貞吉。
象曰：酒食貞吉，以中正也。

上六：入于穴，有不速之客三人來，敬之終吉。
象曰：不速之客來，敬之終吉。雖不當位，未大失也。

一位想找出事物之『bug』，然後『de-bug』者，該歸之何類耶？

論語‧雍也

子曰：知之者不如好之者，好之者不如樂之者。

『觀物』將成為『系統』，進而可作『實驗』乎！

Experiment

An experiment is a procedure carried out to support, refute, or validate a hypothesis. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Experiments vary greatly in goal and scale, but always rely on repeatable procedure and logical analysis of the results. There also exists natural experimental studies.

A child may carry out basic experiments to understand gravity, while teams of scientists may take years of systematic investigation to advance their understanding of a phenomenon. Experiments and other types of hands-on activities are very important to student learning in the science classroom. Experiments can raise test scores and help a student become more engaged and interested in the material they are learning, especially when used over time.^[1] Experiments can vary from personal and informal natural comparisons (e.g. tasting a range of chocolates to find a favorite), to highly controlled (e.g. tests requiring complex apparatus overseen by many scientists that hope to discover information about subatomic particles). Uses of experiments vary considerably between the natural and human sciences.

Experiments typically include controls, which are designed to minimize the effects of variables other than the single independent variable. This increases the reliability of the results, often through a comparison between control measurements and the other measurements. Scientific controls are a part of the scientific method. Ideally, all variables in an experiment are controlled (accounted for by the control measurements) and none are uncontrolled. In such an experiment, if all controls work as expected, it is possible to conclude that the experiment works as intended, and that results are due to the effect of the tested variable.
