Math & Science ⇒ What should be the natural spacement between equations?

[Johannes_B]

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?

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:

Code: Select all

\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}
