Electrical phenomena, caused by the presence and flow of electric charge, have been studied since antiquity. Static electricity was the first of them to be recognized and investigated.

Some 2,200 years later, English scientist William Gilbert coined the term "electricity" to describe the electrification of substances. How did he come up with the word?

Hodgkin developed a passion for chemistry at an early age and went on to become a leader in the field of X-ray crystallography. In 1948, she and her colleagues made the first X-ray photograph of vitamin B12—one of the most complex nonprotein compounds—and eventually determined its atomic arrangement. Her work in determining its structure, as well as that of other biochemical compounds, won her a 1964 Nobel Prize. In 1969, Hodgkin completed a similar three-dimensional analysis of what hormone?
