Models of Classical Physics is the second volume of Science by Simulation. It is a recipe book of mathematical models that can be enlivened by the transmutation of equations into computer code. In this volume, the examples represent the standard canon of Classical Physics (Mechanics, Thermodynamics, Waves and Optics, Electromagnetism) and are based upon paradigm problems and systems that all pre-university and undergraduate STEM students should have the opportunity to experience and, in time, master. Rather than the 'what' of Science, this book is aimed at the 'how', providing guidance that can be readily applied to projects by students and professionals. Written in a friendly style based upon the author's expertise in teaching and pedagogy, this mathematically rigorous book is designed for readers to follow arguments step by step with stand-alone chapters (and indeed sections) which can be read independently. This approach will provide a tangible and accessible context for the development of a wide range of interconnected mathematical ideas and computing methods that underpin the practice of Science, and Physics in particular.
