Maths

Here is some inline mathematics: \(z = 2\).

Unumbered equation: \[ F(x) = \int_0^x f(t) dt \]

Using the equation environment in Eq. eq:numbered.

\begin{equation} F(s) = \int_0^\infty f(t) e^{-st} dt \label{eq:numbered} \end{equation}

Using the align environment Equations eq:align_1 and eq:align_2.

\begin{align} \mathcal{F}(a) &= \frac{1}{2\pi i}\oint_\gamma \frac{f(z)}{z - a}\,dz \label{eq:align_1} \\ \int_D (\nabla\cdot \mathcal{F})\,dV &=\int_{\partial D}\mathcal{F}\cdot n\, dS \label{eq:align_2} \end{align}

Below is a quote.

Nobody ever figures out what life is all about, and it doesn't matter. Explore the world. Nearly everything is really interesting if you go into it deeply enough.
