Can we exponentiate d/dx? Vector (fields)? What is exp? | Lie groups, algebras, brackets #4MathemaniacPosted to r/3Blue1Brown: Grant's video on matrix exponential teases what e^(d/dx) means. Here is the explanation (without resorting to series expansion) with exponentiating vectors and vector fields as well.
