The Jig is Up!

 

It seems as though the term “jig” has an undercurrent of negativism when it comes up in conversation among woodworkers, particularly handtool or traditional woodworkers.

Accuracy is the Enemy of Precision: Part II

Error is a pervasive concept in our lives. Either consciously or subconsciously we seek to eliminate error or to manage error.  When we as a species were roaming the savannahs, error was a life and death concept.  We either ate or we were eaten.  Now, possibly, we balance error versus convenience.  You might even say that error determines the magnitude of risk versus reward.  In many ways, we choose the amount of error that is acceptable to our lives, and for the most part this choice is relative.  When setting the standards for the passage of time, acceptable error is in the millionths of a second.  For firing a rocket for a Moon landing, error might be in milliseconds.  For boiling an egg, it is in seconds.  For managing our airplane flights across the country, acceptable error could be in minutes or hours.

Accuracy is the Enemy of Precision: Part I

An aphorism that I have been hearing frequently is: “accuracy is the enemy of precision”. When I was gainfully employed (I am now retired) I did research at a drug company and also at the EPA.  I dealt every day with the concepts of accuracy and precision.  The reality is that one cannot divide these into separate concepts because they overlap to a very large degree.  A more correct aphorism might be “Accuracy is the Friend Precision”, or alternatively “Without Accuracy There is No Precision” or even “Without Precision There is No Accuracy”.  Continue reading “Accuracy is the Enemy of Precision: Part I”
