Robert Auld, an audio engineer and former chair of the New York chapter of the Audio Engineers Society, is one of many in his trade who sees LRAD deployment as a military-style escalation of force.

“I would characterize it as a terror weapon, up there with tear gas and flash-bang grenades,” Auld tells Popular Mechanics. “The latter are supposed to be ‘non-lethal,’ but they can hurt you. Same for the LRAD.”

In 1687, Sir Isaac Newton published his groundbreaking book, The Principia: Mathematical Principles of Natural Philosophy, which described his three laws of motion. In the process, Newton laid the foundation for classical mechanics and redefined the way the world looked at physics and science.

What most people don't know, however, is that Newton's three laws of motion can be used as an interesting analogy for increasing your productivity, simplifying your work, and improving your life.

Allow me to present this analogy as Newton's Laws of Productivity.
