EXPONENTIAL DECAY Meaning and
Definition
-
Exponential decay refers to a mathematical process in which a quantity decreases over time at a rate proportional to its current value. It is a phenomenon commonly observed in various natural and artificial systems. Exponential decay can be described by an exponential function of the form y = ab^x, where y represents the remaining quantity, a is the initial quantity, b is the rate of decay, and x is the time elapsed.
In exponential decay, the rate at which the quantity decreases is highest at the initial time and gradually slows down as time progresses. This means that the quantity is cut in half during a consistent time interval known as the half-life. The concept of half-life is particularly relevant in radioactive decay, which is a prime example of exponential decay. Half-life refers to the time taken for half of the radioactive substance to decay or disintegrate.
Exponential decay is also observed in other real-world phenomena such as population growth, spread of diseases, degradation of materials, and decay of financial investments. In these cases, the exponential decay function helps predict the future behavior of the quantity by utilizing past data and the known decay rate. This mathematical concept plays a crucial role in fields like physics, chemistry, biology, and economics, assisting in various predictions and analyses.

Etymology of EXPONENTIAL DECAY
The etymology of the term "exponential decay" can be traced back to the combination of the word "exponential" and the term "decay".
The word "exponential" comes from the Latin word "exponere", which means "to put out" or "to explain". In mathematics, "exponential" refers to a rate of growth or decline that is proportional to the current value. It is derived from the Latin phrase "exponentia", meaning "multiplicative increase".
The term "decay" comes from the Old French word "decair", which means "to fall off" or "to decline". It later evolved from the Latin word "decadere", meaning "to fall down" or "to deteriorate". In a mathematical context, "decay" refers to a gradual decrease of a quantity over time.
