This is going to be a basic introduction to the circle of ideas that
leads from those numbers called periods to the algebro-geometric
entities giving rise to them (to wit, algebraic varieties and their
cohomology), as well as to the exponential analogues of these concepts.
It hopefully serves as a motivation for cohomological exponentiation, a
powerful procedure that is only partially realized at this point.
