I'm making a beamer presentation and I'd need to scale a specific equation. The slide is built using double dollars math environments which allows me to easily align the left and right columns. Problem is one specifically long equation doesn't fit in the slide, so I wanted to shrink it. Using single dollar math mode does work but it breaks the alignment.
\documentclass[mathserif]{beamer}
\usepackage{physics}
\usepackage{graphicx}
\begin{document}
\begin{frame}
\begin{columns}[T]
\begin{column}{0.48\textwidth}
\centering
Osservabile: $N$
Stati: $\ket{\psi_1}, \ket{\psi_2}, \dots \ket{\psi _N}$
Misure: $a_1, a_2, \dots a_N$
\vspace{5mm}
Super-posizione
$$N: \ket{\Psi} = c_1 \ket{\psi_1} + c_2 \ket{\psi_2} \dots c_N \ket{\psi_N}$$%this is the equation I would like to shrink
Collasso della funzione d'onda
$$p(a = a_N) = |c_N|^2 \qquad \ket{\Psi} = \ket{\psi_N}$$
\end{column}
\begin{column}{0.48\textwidth}
\centering
Osservabile: $Gatto$
Stati: $\ket{\omega}, \ket{\xi}$
Misure: $vivo, morto$
\vspace{5mm}
Super-posizione
$$Gatto: \ket{\Gamma} = c_V \ket{\omega} + c_M \ket{\xi}$$
Collasso della funzione d'onda
$$p(a = vivo) = |c_V|^2 \qquad \ket{\Gamma} = \ket{\omega}$$
\end{column}
\end{columns}
\end{frame}
\end{document}
Using
\scalebox{0.8}{$$N: \ket{\Psi} = c_1 \ket{\psi_1} + c_2 \ket{\psi_2} \dots c_N \ket{\psi_N}$$}
Breaks the entire slide and using single dollar math mode works, but breaks the alignment.
I unfortunately cannot make more slides since I have a very strict number of slides limit.
