This hands-on book takes a look at four brilliant women -- Ada Lovelace,
Anna Atkins, Hildegard Von Bingen, and Maria Telkes -- and the
world-changing innovations they created. Walk in their footsteps as you
discover how these women became inventors, learn what inspired them, and
then try your hand at recreating their most famous inventions --
computer programs, solar photography, codes and ciphers, and water
purifiers.
