Hidden Figures meets Rosie Revere, Engineer in this STEM/STEAM
picture book about Edith Clarke, the innovator who solved an electrical
mystery and built the first graphing calculator--from paper!
Long before calculators were invented, little Edith Clarke devoured
numbers, conquered calculations, cracked puzzles, and breezed through
brainteasers. Edith wanted to be an engineer--to use the numbers she saw
all around her to help build America.
When she grew up, no one would hire a woman engineer. But that didn't
stop Edith from following her passion and putting her lightning-quick
mind to the problem of electricity. But the calculations took so long!
Always curious, Edith couldn't help thinking of better ways to do
things. She constructed a "calculator" from paper that was ten times
faster than doing all that math by hand! Her invention won her a job,
making her the first woman electrical engineer in America. And because
Edith shared her knowledge with others, her calculator helped electrify
America, bringing telephones and light across the nation.
