- Hopper, Grace Murray
- Description
- This bundle consists of about one hundred pieces of plastic-coated wire, each about 30 cm (11.8 in) long. Each piece of wire represents the distance an electrical signal travels in a nanosecond, one billionth of a second. Grace Murray Hopper (1906–1992), a mathematician who became a naval officer and computer scientist during World War II, started distributing these wire "nanoseconds" in the late 1960s in order to demonstrate how designing smaller components would produce faster computers.
- The "nanoseconds" in this bundle were among those Hopper brought with her to hand out to Smithsonian docents at a March 1985 lecture at NMAH. Later, as components shrank and computer speeds increased, Hopper used grains of pepper to represent the distance electricity traveled in a picosecond, one trillionth of a second (one thousandth of a nanosecond).
