Some useful LaTeX code

Aligning and spacing

${\begin{aligned}3+x&=4&&{\text{we are trying to solve for }}x\\[6pt]x&=4-3&&{\text{Subtract 3 from both sides}}\\x&=1&&x{\text{ must be one}}\end{aligned}}$

Boundaries of integration

Standard way:

$\int _{0}^{\infty }e^{-ax^{2}}\,dx={\frac {1}{2}}{\sqrt {\frac {\pi }{a}}}\qquad {\text{and}}\qquad \iiint _{\mathbb {R} ^{3}}\langle \Psi |\Psi \rangle \,dx\,dy\,dz=1$

Preferred way:

$\int \limits _{0}^{\infty }{\frac {\sin x}{x}}dx={\frac {\pi }{2}}\qquad {\text{and}}\qquad \iiint \limits _{\mathbb {R} ^{3}}e^{-a(x^{2}+y^{2}+z^{2})}\,dx\,dy\,dz=\left({\frac {\pi }{a}}\right)^{3/2}$

Nice quotes

“ If you don't talk the way they understand, you'll not become their friend. ” — Cédric Villani.

“ Rise above oneself and grasp the world. ” — Attributed to Archimedes

“ I don't try to do very much that is obviously flashy. I try to focus on the fundamentals of the material. I very much enjoy trying to get a complete grasp of the subject I'm trying to teach so that I can present it in a clear, consistent and thorough way. ” — Robert M. Wald
