尋找解決的方法
你喜歡謎題嗎?歐拉喜歡。你有沒有解決一個你聽到的任務?不!嗯,別擔心,歐拉也一樣!因為他熱愛數學難題,他想知道這個為什麼不行。所以他繞著小鎮,在哥尼斯堡橋梁反復走了好幾次。令他吃驚的是,他發現,他可以一次性穿過六座橋在一座橋不走兩次或走回頭路的情況下(見圖3),但是他卻不能穿過所有的七座。他只想知道為什麼。所以他決定換一種方式看這個問題。
他把鎮子和七個橋畫在畫上。並標志了土地和橋梁。然後他在每個地區的土地上打點。他將點通過橋梁用曲線連在一起 (請參閱圖1)。他注意到一些點只要三條線通過(A,B和C)另一個有五條線經過(D)。他想這是否重要,並且想知道為什麼這樣不行。三加五是奇數，他稱他們為「奇數的」點。為了使謎題更加清晰，他擦去了橋使模式變得清晰(見圖2)。
他想知道如果他去掉一個橋這個難題是否將解開 (如圖3)。這一次的圖更簡單些(如圖4),他數了數連接點A,B,C和d 的線.這一次不同了。其中兩個線變了(B有兩個和D有四個)。2和4都是偶數，所以歐拉稱他們為「偶數的」點。在圖4有兩個點的連線是奇數(A和C都有三個),所以他稱他們為「奇數的」點。
使用這個新的圖，歐拉從A點開始，沿著直線到B,然後到C。然後他跟著曲線通過D並回到A 。最後他通過另外的曲線從D到C,這一次它完成模式了。他已經能夠通過圖上的每個點，但不會通過任何一條線兩次或將鉛筆離開紙面。歐拉變得非常興奮。現在他知道奇數的點是拼圖的關鍵。但是, 如果你想要完成，你的圖仍然需要一些偶數點。所以歐拉尋找到一個一般規則:
如果一個圖有超過兩個奇數的點,你不抬起鉛筆或通過一條線兩次不能完成。
很快他去他的課本找到更多的數據。他看了看下面四個圖,發現當他利用他的規律,他可以告訴他是否可以不將鉛筆離開紙而通過整個圖。他喜出望外。他不知道,但他的這個小難題已經發展一個全新的叫做「拓撲」的數學分支。為了紀念他，這個謎題被稱作是「尋找的歐拉路徑」。
