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.

What goes up, must come down*

This month we will discuss the movie, The Martian, from an engineering point of view, then talk of something way more important. And, oops, I have to throw in two music videos, just because I can.  Let's start with Mumbles.... 


Clark Terry died in February 2015, at 94 years old.  He was the first African American to appear in a band on a regular television show, in Johnny Carson's Tonight Show on NBC, starting in 1960 and ending in 1972.  He had played in both Count Basie and Duke Ellington's orchestras, and was a WWII vet. Read his obit here. In case you don't understand scat, let me spell out the actual title of this song: Angyumaluma Bongliddleany Nannyany Awhan Yi!
