Before astronauts went into space or before Neil Armstrong walked on the moon, there were a group of dedicated women mathematicians who made it possible. The women were known as "computers" who manually calculated the numbers that would launch planes, rockets and astronauts.
I saw the movie before reading the book. I thought the book was going to read like a fiction novel but, it read more like a textbook. I had a hard time keeping track of the different women. However, I thought it was an interesting read and well researched book.
