Engineering is a diverse branch of science and technology devoted to designing, building, problem-solving and finding practical uses for scientific discoveries. Live Science guides you through the different types of engineering— mechanical engineering, electrical engineering, chemical engineering, aerospace engineering and many more — with explainers on everything from who invented the telephone to how Bluetooth works.
Our expert writers and editors also scour the internet to break down the biggest engineering stories of the day, like biodegradable bullets or the world’s longest bridges. So, if you've got a mind for the mechanical, check out our latest engineering news, features and articles.
