Small Inventions That Made a Big Difference - Helen Pilcher Pockets, matches, spectacles, postage stamps. Whether it's the stitches that hold our clothes together or the syringes that deliver life-saving vaccines, small things really do make a big difference. Yet these modest but essential components of everyday life are often overlooked. Science and comedy writer Helen Pilcher shares the unexpected stories of 50 humble innovations – from the accidental soldering of two bits of metal that created the pacemaker, to the eighteenth-century sea captain whose ingenious invention paved the way for the filming of Star Wars – and celebrates the joy of the small yet mighty. Book Description Small inventions can tell the greatest of tales! This is a fascinating look at small, seldom-noticed and apparently insignificant objects and inventions that have changed the world.
