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.
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:
In nuclear physics, the Bateman equation is a mathematical model describing abundances and activities in a decay chain as a function of time, based on the decay rates and initial abundances. The model was formulated by Ernest Rutherford in 1905 [ 1 ] and the analytical solution was provided by Harry Bateman in 1910.
The first models of nitrogen uptake and release in the body of a diver used five parallel compartments with half times from 5 minutes to 75 minutes. [1] [2] Later models refined this by considering more compartments and a wider range of half times. The U.S. Navy tables used six compartments with half times of 5, 10, 20, 40, 80 and 120 minutes.
The relationship between the elimination rate constant and half-life is given by the following equation: = / Because ln 2 equals 0.693, the half-life is readily calculated from the elimination rate constant.

With the premiere of “The Simple Life” in 2003 on Fox, Hilton — the heiress to the eponymous hotel chain — and Richie — the adoptive daughter of Lionel Richie, became proto-reality stars
Real ones know that Richie was the true star of The Simple Life. Her deadpan humor and over-the-top antics are, in large part, what kept the OG reality series relevant these last 20 years.
