Most of us these days have experienced the communication method known as texting. If you have not texted before, I commend you for getting by this long in life using more traditional methods of communication such as speaking.
One of the skills used in texting requires knowledge and use of abbreviations. Some of the more common ones are LOL for “laughing out loud” or BRB for “be right back.” Engineers and scientists have used abbreviations for centuries to tell a story. Examples include gpm to describe the amount of fluid moving from one location to another, or psi to describe the amount of pounds force applied to an area of 1 square inch.
