Physics is the most basic and fundamental of all the sciences. Studying physics means trying to understand how things work, in every detail and at the deepest level. This includes everything from elementary particles, nuclei, atoms, molecules, macromolecules, living cells, solids, liquids, gases, plasmas, the atmosphere to living organisms, the human brain, complex systems, supercomputers, planets, stars, galaxies and the universe itself. Physics has the reputation of being a difficult subject to master but there are a number of reasons why it is a good idea to do a course in physics. For one thing, most modern technology involves physics. Any technology involving electricity, magnetism, force, pressure, heat, light, energy, sound, optics, etc., comes from physics. Indeed, physics lies in the basis for all types of analytical and measuring systems. Even though the basic knowledge required for products like fertilizers, drugs, plastics, and chemicals comes from chemistry and biology, these items have to Physics offers something that other theoretical subjects cannot - you can see real life applications of it directly. I did not choose physics. Physics chose me! I've wanted to study physics for almost as long as I can remember. I love the feeling of solving a really tough problem.
