The X-ray

"I have seen my own death," said Anna Bertha Röntgen when she saw the very first X-ray image which represented her hand. Her husband, Wilhelm Conrad Röntgen, discovered X-rays in 1895, one of the most important innovations in the history of medicine.

Suddenly it became possible for doctors to look into the human body without surgical operations. X-rays are created when small particles travel at the speed of light and hit something that makes them slow down. The images that appear are either light or dark depending on which tissue the particles hit. 

These days the X-ray is used in a number of fields. Art historians who examine old paintings and customs officers are examples of occupations that use the technique.
