Geek girl's guide to geek women : an examination of four who pushed the boundaries of technology

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.
