"The human body is a complex system made of numerous parts. The backbone of the body is your bones! Whether it's in regard to health or even a skeleton costume on Halloween, the discovery of the X-ray machine has greatly improved our understanding of the human body and its bones. The technology for X-rays dated back to the late nineteenth century but was in plain sight for years until their true potential was discovered by accident. This volume introduces readers to the story of their discovery and how they've changed medicine for the better since!"-- Provided by publisher.
