The Lie bracket of $\mathfrak{gl}(n, \mathbb{C})$ is given by

$$[X, Y] = XY - YX.$$

The following is due to Euler:

$$\sum_{n = 1}^\infty \frac{1}{n^s} = \prod_{p \textrm{ prime}} \frac{1}{1 - p^{-s}}.$$

測試：

$$\int_{空間} d\omega$$
$$\require{AMScd} \begin{CD}K(你) @>{人生}>> H(你;\mathbb Q);\\@VVV @VVV \\K(我) @>{人生}>> H(我;\mathbb Q);\end{CD}$$

There are three crazy guys in mathematics:

1. Hilbert
2. von Neumann
3. Grothendieck
