Rules of Thumb

Sometimes complex behavior can be interpreted in three seconds if you are familiar with our Rules of Thumb. A microwave Rules of Thumb could be an inexact but notable relationship of one or more design parameters with performance, or it could just be an easy way to remember something that other, lesser people often mix up.

The Unknown Editor

"Important Information! Open Immediately!" Whenever you see these words on an envelope, it means the exact opposite: you should discard it immediately! Hopefully, this important tidbit will actually be helpful to you. If not, no harm done, I write to amuse myself and horrify friends and family!

In order to keep you reading, I am offering a contest somewhere on this page, where the winner could get to pull a Benjamin out of my wallet. Be sure to check it out!
