### What should be the natural spacement between equations?

Your book is about physics. Equations in physics need some space. Do you want equations to have the same distance from one another in all of the 2000+ pages?
The smart way: Calm down and take a deep breath, read posts and provided links attentively, try to understand and ask if necessary.

### What should be the natural spacement between equations?

Johannes,

what I'm asking is that all the equations in a given math environment (gather and align) are equaly spaced vertically. I want to get this equal vertical spacing for all align and gather environments. If an equation is really bigger than some other, I'll put it in a separate environment, of hand adjust the spacing in its case.

I hate the variable spacings. It looks horrible!

perhaps \vphantom is what you're really after:
\documentclass[11pt,letterpaper,twoside]{book}
\usepackage{lmodern}
\usepackage{amsmath}
%\setlength{\jot}{\baselineskip}

\newcommand*\bigstrut{\vphantom{\frac{A^2}{y^2}}}

\begin{document}

Blabla:
\begin{gather}
\bigstrut x^2 - \frac{1}{2} \, x = 3, \\
\bigstrut \frac{a^2}{b^3} \, y + 2 x \, y = y^2, \\
\bigstrut a - b = c.
\end{gather}

\end{document}
