Yvonne Clark had an engineering spark—an instinct for figuring out how things worked. Broken lamp? She screwed, rewired, and wrenched until…light! Wrecked radio? She twisted, snipped, and hammered until…music! Clogged furnace? She picked, plucked, and cleared until…heat! When she grew up, Yvonne’s problem-solving power took her to NASA, where fellow engineers had a serious problem with the Saturn V rocket’s F-1 engine: It had hot spots—high temperatures in the engine. Can Yvonne Clark and her engineering spark solve the problem?

However, her work often went unrecognized by male scientists of the time, and she received little credit until long after her death. Learn about Mary Anning's perseverance and her important discoveries in paleontology.
