Boolean

Word of the day: Boolean Yup, on the threshold of my 40s, I have finally discovered that algebra has its uses. 😀 After half an hour of wracking my head about why my SQL query was showing an error on ArcGIS, I asked my husband who used to be a software engineer in another life for help. He cannot understand why I want to complicate my life with map-drawing but managed to find a solution to my problem. That's when I came across Boolean. Someone called George Boole from the Ireland of the 19th century thought algebra must have words like "Is", "And", "Or" and "Not". Look it up. 😁
