This time is called the half-life, and often denoted by the symbol t 1/2. The half-life can be written in terms of the decay constant, or the mean lifetime, as: / = = (). When this expression is inserted for in the exponential equation above, and ln 2 is absorbed into the base, this equation becomes:
Instead, the half-life is defined in terms of probability: "Half-life is the time required for exactly half of the entities to decay on average". In other words, the probability of a radioactive atom decaying within its half-life is 50%. [2] For example, the accompanying image is a simulation of many identical atoms undergoing radioactive decay.
The voltage (v) on the capacitor (C) changes with time as the capacitor is charged or discharged via the resistor (R) In electronics, when a capacitor is charged or discharged via a resistor, the voltage on the capacitor follows the above formula, with the half time approximately equal to 0.69 times the time constant, which is equal to the product of the resistance and the capacitance.
Half-exponential functions are used in computational complexity theory for growth rates "intermediate" between polynomial and exponential. [2] A function f {\displaystyle f} grows at least as quickly as some half-exponential function (its composition with itself grows exponentially) if it is non-decreasing and f − 1 ( x C ) = o ( log x ...
The functional square root of the exponential function (now known as a half-exponential function) was studied by Hellmuth Kneser in 1950. [1]The solutions of f(f(x)) = x over (the involutions of the real numbers) were first studied by Charles Babbage in 1815, and this equation is called Babbage's functional equation. [2]

The doubling time is a characteristic unit (a natural unit of scale) for the exponential growth equation, and its converse for exponential decay is the half-life. As an example, Canada's net population growth was 2.7 percent in the year 2022, dividing 72 by 2.7 gives an approximate doubling time of about 27 years.
