This is especially true of words we use very frequently, but whose concepts are anything but well-understood. “Light”, “energy”, “force”, and “gravity” are [more …]
Richard Feynman is a great popularizer of physics. He mastered the mathematics of light and wrote the QED, which is the most accurate and detailed description of the behavior of light, which is accessible to a lay audience. The following links are to a series of videos on You Tube. Similar to Six Easy Pieces, [more …]
Everyone knows Albert Einstein’s famous equation, but do you know why he was awarded the Nobel Prize? It was not for Relativity, but for giving birth to the Quantum Universe, which is in direct conflict with the Relative Universe! … Thanks to QED we know that all known physical phenomena in the universe from the [more …]
