Many texts present Lie algebras as a "linearized version" of Lie groups. Sternberg proves why: For a matrix group $G$, every group element near the identity can be written as $e^X$ for some Lie algebra element $X$. He then shows that the unitary representations of the group correspond one-to-one to Hermitian representations of the algebra—explaining why observables in QM are Hermitian operators. group theory and physics sternberg pdf

Let’s extract three profound ideas that Sternberg explains better than almost anyone else. , published by Cambridge University Press in 1994
