This field includes careers that require the use of analytical skills to solve complex problems. Scientists are curious, independent thinkers who seek to understand and explain the natural world. They often have a natural aptitude and interest in science and mathematics. However, whilst some individuals prefer the more practical aspects of working with nature, others prefer the research component, which includes working with formulae and complex mathematical problems. Success in Natural Sciences requires a commitment to study and the acquisition of specialised knowledge in certain fields. Knowledge and the ability to apply that knowledge distinguish one scientist from another. Good scientists become experts in their respective fields of interest.
