Hidden Engineering: How Energy, Transport and Safety Shape Everyday Life

How many engineered systems are encountered on an ordinary journey from a bedroom to school? A plug connects an appliance to an electrical supply, a radiator transfers heat, and a kettle uses electricity before a bicycle, bus, pavement and crossing organise movement outside. This raises the central enquiry: how many systems can shape one day, and how do they reduce danger? Engineering includes small household objects, buildings, transport systems and public infrastructure, not only enormous machines.
