I want to make a list of Quantum Mechanics formula like the format of the following picture. But I am confused about how to make the equations align to the left while the text to the right. Usually, if I use environment like,
Equation, the equation will be at the center.
I know I can use
fleqn package, but it does not align the equations to the left enough as wee see from the picture I attached. My thought to approach this is to use
fleqn, then put in the
align environment, then use a bunch of
\qquad to align for the text part, which is on the right side of the page. But I think this is silly.
Can anyone give me an example of this format? Or does anyone know if there are some cool packages for me to use so that my formula list would look as nice as this one?
