  Exponential growth - Wikipedia, the free encyclopedia
In mathematics, a quantity that grows exponentially is one whose growth rate is always proportional to its current size.
This is the reason that exponentially increasing the brightness of visual stimuli is perceived by humans as a smooth (linear) increase, rather than an exponential increase.
The resulting exponential growth of electrons and ions may rapidly lead to complete dielectric breakdown of the material.

 Exponential function - Wikipedia, the free encyclopedia
If a variable's growth or decay rate is proportional to its size — as is the case in unlimited population growth (see Malthusian catastrophe), continuously compounded interest, or radioactive decay — then the variable can be written as a constant times an exponential function of time.
The exponential function maps any line in the complex plane to a logarithmic spiral in the complex plane with the center at the origin.
The definition of the exponential function given above can be used verbatim for every Banach algebra, and in particular for square matrices (in which case the function is called the matrix exponential).

 The Law of Accelerating Returns
In exponential growth, we find that a key measurement such as computational power is multiplied by a constant factor for each unit of time (e.g., doubling every year) rather than just being added to incrementally.
There are a great many examples of the exponential growth implied by the law of accelerating returns in technologies as varied as DNA sequencing, communication speeds, electronics of all kinds, and even in the rapidly shrinking size of technology.
If we view the exponential growth of computation in its proper perspective as one example of the pervasiveness of the exponential growth of information based technology, that is, as one example of many of the law of accelerating returns, then we can confidently predict its continuation.

Exponential growth rates may take the form of annual growth rates, quarter-on-previous quarter growth rates or month-on-previous month growth rates.
The exponential growth rate is the growth rate between two points in time for certain population indicators, notably labour force and population.
This growth rate is based on a model of continuous exponential growth between two points in time.

 Math in Daily Life -- Population Growth
With population growth, new members of the population eventually produce other new members of the population.
To arrive at a reasonable estimate of how the world's population will grow in the next 50 years, you need to look at birth and death rates (the rates at which people are being born and dying in any given period).
If birth and death rates stayed the same across the years in all parts of the world, population growth could be figured with a fairly simple formula much like the one used to figure compound interest.

 Exponential Growth: The Andromeda Strain
To investigate a simple example of exponential growth in both discrete and continuous growth situations.
Since we are interested in growth over a period of hours, express the doubling time in terms of hours.
If we know the doubling time associated with the growth of some particular species, and we convert our calendar units (days, weeks, years, etc) to multiples of the doubling time, then the process of growth (on that scale) would look identical to the one we already studied for bacteria in this example.

 EcoFuture™ Population and Sustainability - Exponential Growth and The Rule of 70
The use of natural logs arises from integrating the basic differential equation for exponential growth: dN/dt = rN, over the period from t=0 to t = the time period in question, where N is the quantity growing and r is the growth rate.
For the results to be accurate, all of these calculations assume that the growth rate remains unchanged throughout the interval in question, that is, that the growth is exponential at the average rate for the entire period.
When considering growth over a period of years, it is important to note that taking the natural logarithm of the ratio of the final value to the initial value and dividing by the time period in years gives the average annual growth rate.

There is a whole hierarchy of conceivable growth laws that are sub-exponential and also super-linear, and of course faster than exponential growth is also possible.

 An examination of Rick Warren’s teaching on “exponential growth”
on exponential growth, presented by Warren, is one of the most shocking teachings I have ever seen emerge from a Southern Baptist.
Warren’s promise in this point is contingent upon the validity of the concept of “exponential growth.”  As we are discovering, the entire premise is wrong and, therefore, this comment is irrelevant.
“exponential thinking keeps you from making the mistake of setting up a system that won't get bigger.”  He said the church is “stuck in a shoe that isn't able to get any bigger.”  This is due to our faulty thinking.
