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

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

Next let's make some chapter headings.

Chapter 1

Chapter 2

Chapter 3

Chapter 4
