费马大定理逻辑思维-费马大定理逻辑推理

费马大定理这事儿，说白了就是问：$z^n + w^n = t^n$ 里的 $n$ 要是 2 次方，那 $z$、$w$、$t$ 这三个数加起来能全是整数吗？老费马（Pierre de Fermat）给这难题打了个大大的问号，说“不知道”。
后来 Euler 老头子回答“知道”，但得是整 $n$ 才行，不是 2。现代数学家更是把范围放宽到了无穷大整数，这作业实际上忒好办，连玩泥巴小孩都能算，如何老费马就扒不出来呢？ 大量人认定这是个大难题，实际上不然。$n=3$ 时就有解了，比如 $3^3 + 4^3 = 5^3$，这就像 $3 times 3 + 4 times 4 = 5 times 5$ 那样，小学高年级就懂。$z^2 + w^2 = t^2$ 是勾股定理，那是写进教科书里的，任何高中文科生都知道如何解。
故此费马大定理在 $n=2$ 时大约率就是假的。但数学界有个绝活，叫“逆向思维”要么叫“坏消息”。
要是题目里藏着假的东西，那你越往深处钻，就越能把它挖出来。 欧拉说 $n$ 要是偶数，这结论是对的。费马自己也是如此认定，故此他拿着证明书满世界转，说“我没想到 $n$ 要是奇数”。
后来有人发现 $n=3$ 确实是解。
那 $n=5$ 呢？有人算到 $n=7$，还有人算到 $n=10$。到了 $n=13$，欧拉另一本书里又提到了，自然，那个 $n$ 要是偶数。但奇数 $n$ 呢？没人管了。数学界有个习惯，就是要是前面的数都成立，那后面的数大约率也成立。
故此欧拉当时心想，"n=2,3,4,5,7,8,9,10,13" 全都对了，那 $n=12$ 呢？费马大猜想肯定是对的。 可现实是，n=12 的结局是假的。19 世纪的法国数学家 A. 勒让德算出了 $n=12$ 的解：$6855^3 + 18405^3 = 257879246^3$。
这玩意儿直接把费马的大猜想砸了个稀巴烂。
那时候大家都在赌，赌 $n$ 要是偶数。赌输了，如何赌？ 费马大定理的解法直接绕开了所有正规数学流程。你得先把方程拆开，分成 $x^3 + y^3 = z^3$ 和 $x^3 + y^3 = k z^3$ 两块。
第一块分得特别好办，就是找两个勾股数的乘积，用平方差公式一拆，再除以某个数，就能得出整数解。
第二块就更难了，这就是费马大猜想真正的核心。 实际上 $n=3$ 的解法也挺明显。
要是两边都除以 $x^3$，拿到 $1 + (y/x)^3 = (z/x)^3$。设 $y/x = a$，$z/x = b$，那就是 $1 + a^3 = b^3$，也就是 $1 = b^3 - a^3$。
这是立方数差，挺好办。
比如 $3^3 = 27$，$4^3 = 64$，差就是 $37$，不对。但 $9^3 = 729$，$10^3 = 1000$，差是 $271$。
什么的，费马想的是 $x^3 + y^3 = z^3$ 这种形式。$3^3 + 4^3 = 27 + 64 = 91$，不是彻底立方。
哦对，是 $3^3 + 4^3$ 不对，应当是 $3^3 + 4^3$ 吗？不对，原方程是 $z^n + w^n = t^n$。$n=3$ 时，$3^3 + 4^3 = 27 + 64 = 91$，这不是 $5^3=125$。啊，我记混了。$3^3 + 4^3$ 是 91。$3^3 + 6^3 = 27 + 216 = 243 = 3^5$，不对。$2^3 + 3^3 = 8 + 27 = 35$。$4^3 + 6^3 = 64 + 216 = 280$。$5^3 + 12^3 = 125 + 1728 = 1853$。$2^3 + 3^3 = 27 + 8 = 35$。$2^3 + 6^3 = 8 + 216 = 224$。$5^3 + 12^3$ 是 1853。$125 + 1728 = 1853$。
这个公式得是 $x^3 + y^3 = z^3$。
哦，$3^3 + 4^3$ 不是。$3^3 + 4^3$ 是 91。$2^3 + 6^3 = 224$。$125 + 1728 = 1853$。$216 + 49^3$。$4^3 + 6^3 = 64 + 216 = 280$。$27 + 4000$。$2^3 + (-1)^3$。$(-1)^3 + 2^3 = 7 neq 0$。
