- What's The Tool? -
There is a tool that can be made of various materials, is sometimes very small, sometimes very large, and often in a range of sizes inbetween. Historians tell us that it was probably one of the first tools used by man and that its use extends back several thousand years B.C. Its parts include a rod or bar, a fulcrum, effort and force. So, what is this ancient and modern tool? Yes, of course it is the lever.
The lever is ancient but what about very modern tools? The following description is of a modern tool designed to accomplish very different tasks. Can you figure out what it is - and decide if the suggestion of how such a tool will be manufactured in the future is a real possibility or if I made it up?
In the manufacture of this modern tool a crystal is grown, sectioned very finely and etched using light. The entire manufacturing process is designed to result in a perfect, error-proof product. Over the past few years smaller and smaller versions of this tool have been developed which retain - even improve - its properties. But those who should know believe we are reaching the limit of the size reduction. This very small tool plays a large part in your life but you may never have seen it.
