E-folding
TIME INTERVAL IN WHICH AN EXPONENTIALLY GROWING QUANTITY INCREASES BY A FACTOR OF E
E-folding time scale; E folding; E-foldings
In science, e-folding is the time interval in which an exponentially growing quantity increases by a factor of e; it is the base-e analog of doubling time. This term is often used in many areas of science, such as in atmospheric chemistry, medicine and theoretical physics, especially when cosmic inflation is investigated.
