We're all born with an urge to understand the world around us. This leads us to ask questions such as "How does a mobile phone work?", "How does the Sun keep on shining?", "What is dark matter?", "What are the ultimate constituents of matter?", "How did the Universe begin?". If you find that the more answers you discover, the more questions you want to ask, then you're on the road to becoming a physicist and should be considering taking a physics course in higher education. * As well as being concerned with deep fundamental questions, physics forms the basis of most present and future technology. Without an understanding of the basic physics of a problem, we'd be shooting in the dark. For example, when compact disc players were developed, it was crucial that the physics of solid state lasers and the interaction of light with matter were well understood. This in turn depended on an understanding of atomic physics and quantum mechanics. * Other new technological developments depend on modern physics in a similar way. One of the key ideas in physics is that, behind the complexity of the world around us, there is an underlying simplicity...
