The study of archaeology has long been carried out using tools from the physics lab. Among these are carbon-14 dating, thermoluminescence dating, x-ray photography, x-ray fluorescence elemental analysis, CAT and MRI scanning, ground-penetrating sonar and radar, and many others. What is less well known is that archaeology has also made substantial contributions to physics. This is the story of old lead; why it is important to physics, and what ethical problems it presents to both sciences.
