What is LaTeX class for this book? [closed]

I decided to translate a book but I have hard time to design my own LaTeX template for the book Quantum Mechanics by Leonard Susskind & Art Friedman Below is showing one page: I wonder what kind of LaTeX book class the author uses?

• With the right options and packages, almost every class can look like this... Well it is not standard scrbook, that's for sure. – Skillmon Sep 7 '17 at 21:06
• It doesn't look like original book LaTeX template. I wonder which font they use? – ofenerci Sep 7 '17 at 21:08
• @Skillmon: book with headings pagestyle, amsmath and geometry settings for a5paper etc, perhaps? (At least I have the impression that the page format is rather small) – user31729 Sep 7 '17 at 21:14
• do you knowif it was made with tex at all? – David Carlisle Sep 7 '17 at 21:43
• The font looks like the standard Computer Modern or Latin Modern. – Bernard Sep 7 '17 at 21:57

This recreates the looks of your image (not exactly obviously):

\documentclass[%
numbers=endperiod% For the point after the number, in your image it is used in headmarks but not at the actual headings
,a5paper%
,fontsize=12pt%
,egregdoesnotlikesansseriftitles%
]{scrbook}

\usepackage[markcase=upper]{scrlayer-scrpage}
\usepackage{amsmath}
\usepackage[a5paper,margin=2cm]{geometry}

\clearpairofpagestyles
\automark[chapter]{chapter}%both right and left chapters
\automark*[section]{}%if there is a section right head containing section

\usepackage{blindtext}

\begin{document}
\chapter{foo}
\cleardoublepage
\noindent
Or even more explicitly, we can combine three terms into a single matrix:
$$\sigma_n = \begin{pmatrix} n_z & (n_x - in_y)\\ (n_x+in_y) & -n_z \end{pmatrix}. \label{eq:sigma}$$
What is this good for? Not much, until we find the eigenvectors and
eigenvalues of $\sigma_n$. But once we do that, we will know the possible
outcomes of a measurement along the direction of $\hat{n}$. And we will also
be able to calculate probabilities for those outcomes. In other words, we will
have a complete picture of spin measurements in three-dimensional space. That
is pretty darn cool, if I say so myself.

\section{Reaping the Results}
We are now positioned to make some real calculations, something that should make
your inner physicist jump for joy. Let's look at the special case where
$\hat{n}$ lies in the $x$-$z$ plane, which is the plane of this page. Since
$\hat{n}$ is a unit vector, we can write
\begin{align*}
n_z = \cos\,\theta\\
n_x = \sin\,\theta\\
n_y = 0,
\end{align*}
where $\theta$ is the angle between the $z$ axis and the $\hat{n}$ axis.
Plugging these values into Eq.~\ref{eq:sigma}, we can write
\begin{equation*}
\sigma_n = \begin{pmatrix}
\cos\,\theta & \sin\,\theta\\
\sin\,\theta & -\cos\,\theta
\end{pmatrix}.
\end{equation*}

• Thanks for all comments! I have already typed a few pages of the book with those motivation. I wonder how to remove *the dot" after the section number (1.1.). In the book's section, no dot trailing the section number. – ofenerci Sep 7 '17 at 22:19
• @ofenerci well I know how to change this in KOMA. Just leave out numbers=endperiod in my code. – Skillmon Sep 7 '17 at 22:24
• Now we have a Perseus Books' LaTeX template for their "theoretical minimum" series :) Feature books are now easy to edit. – ofenerci Sep 7 '17 at 22:35
