Physical models have been, and continue to be used by engineers when faced with unprecedented challenges, when engineering science has been non-existent or inadequate, and in any other situation when the engineer has needed to raise their confidence in a design proposal to a sufficient level to begin construction. For this reason, models have mostly been used by designers and constructors of highly innovative projects, when previous experience has not been available. The book covers the history of using of physical models in the design and development of civil and building engineering projects including bridges in the mid-18th century, William Fairbairn?s Britannia bridge in the 1840s, the masonry Aswan Dam in the 1890s, concrete dams in the 1920s, thin concrete shell roofs and the dynamic behaviour of tall buildings in earthquakes from the 1930s, tidal flow in estuaries and the acoustics of concert halls from the 1950s, and cable-net and membrane structures in the 1960s. Traditionally, progress in engineering has been attributed to the creation and use of engineering science, the understanding materials properties and the development of new construction methods. The book argues that the use of reduced scale models have played an equally important part in the development of civil and building engineering. However, like the history of engineering design itself, this crucial contribution has not been widely reported or celebrated. The book concludes with reviews of the current use of physical models alongside computer models, for example, in boundary layer wind tunnels, room acoustics, seismic engineering, hydrology, and air flow in buildings.

Adrian Mole's first love, Pandora, has left him; a neighbor, Mr. Lucas, appears to be seducing his mother (and what does that mean for his father?); the BBC refuses to publish his poetry; and his dog swallowed the tree off the Christmas cake. "Why" indeed.

In Amazing Kitchen Chemistry Projects You Can Build Yourself, kids ages 9 and up will experiment with kitchen materials to discover chemistry. Readers will learn about atoms, molecules, solids, liquids, gases, polymers, the periodic table, the important history of science, and much more. Along the way, they'll make goop, cause chemical reactions, and create delicious treats, and all of it will illustrate important chemistry concepts. Amazing Kitchen Chemistry Projects is a fun and exciting way for young readers to learn all about chemistry and become scientists right in the kitchen.
