This is our fourth and final tutorial on how things move. In tutorials six and seven, we explored how things move and change position. In Tutorial eight, we looked at how far something moves. In this tutorial, we are going to take what was introduced in the previous tutorials to explore solving a question involving distance and position. We’re […]
On February 11, 2016, in front of a world wide audience, scientific history was made. Scientists from around the world announced that gravitational waves had been detected using twin LIGO detectors located in Washington and Louisiana. LIGO, which stands for the Laser Interferometer Gravitational–wave Observatory, is a collaborative experiment involving scientists from some of the leading research institutions in […]
Tutorials six and seven introduced the translation transformation, also called the Newtonian equation. The Newtonian equation, which forms the foundation of classical mechanics is extremely useful and describes how objects move from one place to another. Answering questions about positions is extremely useful. Modern Mechanics, a model we’ll introduce shortly as a superset of classical mechanics and a replacement […]
Imagine you attend the matinee and evening performances of the same play. At the matinee performance, the role of the King is played by Don and the role of the Court Jester is played by Brad. In the evening performance, they swap places: the role of the King is played by Brad and the role […]
Last week, I saw a good friend whom I haven’t seen for a while. He asked: If Einstein is wrong, what does your theory – Modern Mechanics – mean in practical terms? The possible answers to this question are only limited by our imagination. One of the biggest changes is associated with the speed of light; […]
One of the most interesting aspects of physics is that it helps to describe how things move. This characteristic builds upon a mathematical foundation called geometric transformations. While this name, geometric transformation, sounds complicated, some of its most important ideas are actually quite easy to explain. Imagine for a moment that you need to open […]
