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? 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 \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

${\vec {\nabla }}\times {\vec {D}}={\frac {\rho _{ext}}{\epsilon _{0}}}$ (1)

Next let's make some chapter headings.

Chapter 1

Chapter 2

Chapter 3

Chapter 4
