The field of science and technology is a very broad one. Chemistry, physics, computer programming – all these disciplines have a huge impact on human life. You might be wondering what the actual phenomenon is that makes science and technology so important to the world as a whole, and it's a difficult question to answer succinctly. For want of better terms, scientists study how things work while engineers design mechanisms (like buildings) or materials (like steel) in order to make them more efficient at their jobs.
