Dynamic Fields and Waves concentrates on electric and magnetic fields that vary with time, including light and electromagnetic waves. Written for an undergraduate introductory course but equally suitable for self-study, this practical, illustrated book discusses waves in general and light waves in particular, together with optical instruments, such as telescopes and microscopes, and electrical devices, such as generators and transformers. It also explores Einstein's special theory of relativity, which gives the most basic insight into space and time.

Climate change is arguably the most profound challenge facing the international community in the 21st century. It is as much a challenge for poverty reduction, growth and development as it is a global environmental issue.
