Accounting: Using numbers to plan

One of our great advances is our ability to plan. In some cases we plan microseconds into the future. In others we plan days, weeks, even years ahead. How do we do this? If you think about it, being able to imagine a future state for ourselves or objects under our control is an amazing skill. It requires a good sense of self, a good ability to project that self into other circumstances, and an ability to manipulate events. Wow! 

When societies rationed, saved for seed and for bad years, they used accounting to help their plans. Planners had to know: how much grain the population used each year, how much the population grew each year, what the farmer could harvest each year, how much the grain silos could hold, and so on. These numbers were used to  determine what was needed to smooth out the ups and downs of the drought cycle.

In a future post I might talk about microplanning, the calculations a quarterback makes to throw a football to a streaking wide receiver or when we toss keys to our mate over the car at our summer cabin. Accounting scale planning is longer term. We can track things over years and plan years & decades in advance. We use a type of accounting to plan rocket launches, trips to distant planets, and collection of data that will require years of observation to create a useful data set.

As a young child I loved looking at my grandfather's accounting materials. Spreadsheet books, forms that allowed for daily, weekly, monthly and annual entries into journals, sales reports, and other simple records. He entered his clients information with fine mechanical pencils on smooth green tinted pages filled with entries in column and row! I now know that each client used Papa's work to plan, to determine what to buy, whether or not to borrow, when to hire, etc.

As I've gotten older I can see many reasons for accounting even as I try to avoid needing it in my life. I work hard to make a routine that doesn't need records, doesn't need plans, doesn't go past simple, daily acts like: reading, exercising, singing, merry making, bathing, art, and music.

Santa's Birthday Post. The gift of number.

Only 39 weeks 'til Christmas Day. 

I've reached another prime number. Its been six years since I was prime! 

When humans learned to differentiate by number we slowly became more adept at counting. At first we likely could tell the difference between one and more than one. Between few and many. Now we can accurately count up to 71 or 1,234,456,987,543,954. Number sense is a gift passed on from generation to generation. To some extent as we move along the time line of history our past piles up behind us in the form of numbers. Years ago, in the past decade, 200 years ago, 10,000 BCE. These logs or recitations of past events gave new meaning and understanding to our ancestors. We marked off the passing of time by the season and the year. 

Imagine now, when credit default swaps trade over ethernets based on complex algorithms and calculations of future market value assuming a 2.2% growth rate and 1.7% inflation. Numbers fill our life with meaning and confusion. Gifts are not always the boon they are intended to be. In fact a gift's value can change depending on our cultural needs. I'll explore this idea later when I talk about the gift of faith!
