"The vector bundle $\mathcal{M} \times \mathbb{R}^n$ over $\mathbb{M}$ with fiber $\mathbb{R}^n$ is called the trivial $\mathbb{R}^n$ bundle for what I hope is an obvious reason." - CHT, Differential Geometry

"You differentiate it once, you want to differentiate it twice. It's like you give a mouse a cookie it asks for milk." - BHG, Multivariate Calculus
