Engineering impacts many aspects of daily life, from the vehicles we drive, to the software that runs our smartphones and tablets, to the infrastructure that surrounds us. The field of engineering is constantly evolving, and recent technological strides have caused it to change even faster. This volume looks at the ways in which various branches of engineering--including biomedical engineering, civil engineering, computer engineering, and geological engineering--use new technology to improve and optimize life. It also considers how engineers are attempting to meet the challenges of today and the future by addressing the environmental impacts of climate change, incorporating smart technologies into community infrastructure, and treating major health issues like cancer.
