  Each title in this series takes one simple scientific principle as a basis for explaining the workings of a selection of everyday gadgets and machines. The illustrations aim to de-mystify the scientific theory and expose the workings of each machine. Focusing on simple slopes, this book explains the principle of inclined planes and describes the many everyday uses of this most basic of machines - for cutting (scissors and ploughs), lifting (ramps, jacks), fastening (zips, keys) and drilling.
