Physics



String theory, often called the “theory of everything,” is a relatively young science that includes such unusual concepts as superstrings, branes, and extra dimensions. Scientists are hopeful that string theory will unlock one of the biggest mysteries of the universe, namely how gravity and quantum physics fit together.

Physic definition, a medicine that purges; cathartic; laxative. Feb 11, 2019 How Physics Works. As an experimental science, physics utilizes the scientific method to formulate and test hypotheses that are based on observation of the natural world. The goal of physics is to use the results of these experiments to formulate scientific laws, usually expressed in the language of mathematics, which can then be used to predict other phenomena. Physics is the study of matter, motion, energy, and force. Here, you can browse videos, articles, and exercises by topic. We keep the library up-to-date, so you may find new or improved material here over time. New Views of Quantum Jumps Challenge Core Tenets of Physics. One of the most basic processes in all of nature—a subatomic particle’s transition between discrete energy states—is surprisingly.
