Updated for modern times using pennies and a hypothetical question such as "Would you rather have a million dollars or a penny on day one, doubled every day until day 30?", the formula has been used to explain compound interest. (Doubling would yield over one billion seventy three million pennies, or over 10 million dollars: 2 30 −1 ...
The notion of doubling time dates to interest on loans in Babylonian mathematics. Clay tablets from circa 2000 BCE include the exercise "Given an interest rate of 1/60 per month (no compounding), come the doubling time." This yields an annual interest rate of 12/60 = 20%, and hence a doubling time of 100% growth/20% growth per year = 5 years.
If you double 1 penny every day for 30 days, you would end up with over $5 million. This exponential growth showcases the power of compounding over time. The Growth of a Penny that Doubles for 30 Days
The growth constant k is the frequency (number of times per unit time) of growing by a factor e; in finance it is also called the logarithmic return, continuously compounded return, or force of interest. The e-folding time τ is the time it takes to grow by a factor e. The doubling time T is the time it takes to double.
Pennies are everywhere. While most aren't worth much more than, well, a penny, there are others worth a lot more. See: If You Find a Rare 'Doubled Die' Penny, It Could Be Worth $1.14 MillionDo Not...

The solution appears very obvious if the owner withdraws every day only $10 from $50. To add up 40 + 30 + 20 + 10 using the same pattern from above would be too obviously wrong (result would be $100). The answer to the question, "Where did the extra dollar come from?" can be found from consecutively adding the bank rest from three different ...
“The most famous doubled die cent is the 1955 Lincoln cent with the doubling error,” explained Pearlman. “There also are some more recent examples that possibly could be found in pocket ...
