unusual facts about compound interest



Doubling time

It is applied to population growth, inflation, resource extraction, consumption of goods, compound interest, the volume of malignant tumours, and many other things that tend to grow over time.

Fictional currency

In some cases, compound interest may swell small amounts into a fortune, as happens in the Hitchhiker's Guide to the Galaxy by Douglas Adams and When the Sleeper Wakes by H. G. Wells, or the Futurama episode "A Fishful of Dollars".

Meddling Monk

The Monk liked to meddle in history and to change it for his own amusement and for what he considered to be the better: lending mechanical assistance to the builders of Stonehenge; giving Leonardo da Vinci tips on aircraft design; making money by using time travel to exploit compound interest; and, when the Doctor first encountered him, attempting to prevent the Norman Conquest as part of a plan to guide England into an early age of technological prosperity.
