Mapping diamond surfaces using interference

This is my first page. Probably I want a header somewhere.

This is my first project

But, what if I need to make formulas? ${\frac {1}{\sqrt {2\pi \sigma ^{2}}}}e^{-{\frac {1}{2}}{\frac {(x-x_{0})^{2}}{\sigma ^{2}}}}$ I have no idea what that will look like, but let's try it. We can also do vector equations, such as Gauss's Law

Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle \vec{\nabla}\times\vec{D}=\frac{\rho_{ext}}{\epsilon_0}} (1)

Next let's make some chapter headings.

Chapter 1

Chapter 2

Chapter 3
