The Scale Model

Building scale model boats that can sail under their own power is a challenging and rewarding hobby requiring varied skills from woodworking to painting to wiring electrical components. This book details everything you need to know to get started: from the tools, materials and equipment required to motors, servos, propellers and remote controls. There are step-by-step guides to the more challenging procedures. There are details on the different types of kits available and how to choose one. Advice is given on glues, fillers, making silicon moulds, and finishes such as painting, decals and weathering. Finally, there is the building of an off-the-shelf kit for the steam yacht Komet and scratch-built RNLI Lifeboat The Torbay Severn class lifeboat.

This book sheds new light on topological defects in widely differing systems, using the Velocity-Dependent One-Scale Model to better understand their evolution. Topological defects – cosmic strings, monopoles, domain walls or others - necessarily form at cosmological (and condensed matter) phase transitions. If they are stable and long-lived they will be fossil relics of higher-energy physics. Understanding their behaviour and consequences is a key part of any serious attempt to understand the universe, and this requires modelling their evolution. The velocity-dependent one-scale model is the only fully quantitative model of defect network evolution, and the canonical model in the field. This book provides a review of the model, explaining its physical content and describing its broad range of applicability.
