Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves. It helps us to understand how the world around us works, from can openers, light bulbs, and cell phones to muscles, lungs, and brains; from paints, piccolos, and pirouettes to cameras, cars, and cathedrals; from earthquakes, tsunamis, and hurricanes to quarks, DNA and black holes. Studying Physics develops your critical thinking and problem-solving skills. Physicists are versatile, which opens a wide range of future careers.
