Let Go, Tarzan! Tarzan may have skillfully swung across the jungle on vines, but the same physics behind his artful motions also explain the worst belly flops at your local rope swing. So whether you're looking to dodge venomous snakes or make a big splash at the lake, you need to know the precise moment to let go of your swing. For the greatest horizontal distance, you might think a 45 degree angle would always work (when ignoring wind resistance). You'd be wrong, though. Swinging from a pendulum, like a rope swing or hanging vine, is a little more complicated than your classic cannon ball projectile motion. The angle should always be less than 45 degrees, and the precise angle varies among rope swings.
Python beginner's mistakes Every Python programmer had to learn the language at one time, and started out as a beginner. Beginners make mistakes. This article highlights a few common mistakes, including some I made myself. Beginner's mistakes are not Python's fault, nor the beginner's. They're merely a result of misunderstanding the language. Problem Solving & Critical Thinking with Scratch 21st Century Skills Addressed Using Scratch from MIT Students across the world are using computers to develop a host of twenty-first century skills. One of the tools being deployed in classrooms and in after school computer clubs is Scratch, from the Lifelong Kindergarten Group at the MIT Media Lab in Cambridge, Massachusetts. Specifically, Scratch is a media creation tool which allows students to easily create animations, stories, and interactive games. At its core, Scratch is a programming environment which sidesteps learning the syntax required in programming by using Lego-like blocks. This constructionist approach in learning supports critical thinking and problem solving through the creative process when students create, enhance, or troubleshoot their projects.
