Possibilities of Compound Interest. From Law and Legal Pointers A Complete Commercial Instructor and Advisor by J. Edward Heidner, written in Chicago, 1907.

An Idaho correspondent sends the NY Tribue a photograph of an old Idaho morgage, which shows in a startling way the amazing possibilities of compound interest. The mortgage was executed in 1861, on a piece of land in Boise City, "to secure the sum of $340, if paid in legal tender, with interest, at the rate of 10 per cent per month. But if the said note shall not be paid ... then the sum of $170, with interest, at 10 per cent, per month, and if said interest is not paid at the time of maturity of this note, said interest to be added to the principal, and said principal and interest together shall draw interest per month as above stated." These conditions were evidently not fulfilled, for a note is appended to the document as follows: "The above mortgage is not satisifed, according to the records of Ada County. With interest on $170, at 10 per cent per month, compounded every six months, the debt would now amount to $45,972,903,182,926.50." There are a great many millionaires in the country, but there is probably only one man in in the world who is indebted in the sum of nearly forty-six trillions of dollars.

Just want to point out that there are now two men who maintain this level of debt.

There is no force greater in the universe than that of compound interest.

You take the emotion of "money" out of it, and interest is just mathematics. Interest is merely a multiplier of numbers. It's an exponential function.

These have been posted before. It's in 8 parts.

Wow, nearly 3 million hits for a mathematics youtube.

The vexing thing about an exponential growth function: everything happens at the last minute! The growth seems to explode - in fact it does explode. Exponential growth in monetary systems is a recipe for sudden disasters and therefore is to be avoided, always.

In an exponential function, the rate of change is continuously increasing.

So in theory, this man has contributed greatly to the economy. He has added as much to the money supply as has the Chairman of the Fed?

If you "invested" one penny in the year 00 (Birth of Christ) at an interest rate of 3%, it would now be worth 6.54 X 10^23rd dollars. That would be six and a half hundred billion trillions.

Exponential functions are like that, raise anything to the 2011th power-----
