With today's modern technology, LEDs, servomotors, motion sensors, speakers, and more artwork can incorporate elements of light, sound, and motion for dramatic effects. Author and educator Simon Quellen Field has developed a primer for creative individuals looking for new ways to express themselves though electronically enhanced art. Following step-by-step examples of basic circuitry and programming, readers can develop the skills necessary to enhance...
Black powder, the world's first chemical explosive, was originally developed during the Tang dynasty in China, in the seventh century. It was a crude mixture at first, but over time chemists discovered the optimum proportion of sulfur, charcoal, and nitrates, as well as the best way to mix them so that the particles of each component were tiny and homogenous, resulting in a complete and powerful reaction. Author and chemistry buff Simon Quellen Field...
Exploring the scientific principles behind everyday recipes, this informative blend of lab book and cookbook reveals that cooks are actually chemists. Following or modifying recipes is shown to be an experiment with acids and bases, emulsions and suspensions, gels and foams. This easy-to-follow primer includes recipes that demonstrate the scientific concepts, such as Whipped Creamsicle Topping (a foam), Cherry Dream Cheese (a protein gel), and Lemonade...
