viaduct

Definition

A long bridge-like structure consisting of a series of arches or towers carrying a road or railroad over a valley, river, or other obstacle at considerable height.

Example Usage

The ancient Roman viaduct still stands after two millennia, testament to the engineering prowess of classical civilization.

Origin

From Latin 'via' (way or road) and 'ducere' (to lead), literally 'something that leads along a way'.

Fun Fact

Roman viaducts often carried not just roads but also water channels for aqueducts, combining transportation and water management infrastructure in a single structure.

fermi

An obsolete scientific unit equal to one femtometer (10⁻¹⁵ meters), named after physicist Enrico Fermi because apparently scientists enjoy naming impossibly tiny measurements after their colleagues. This is the scale where you're measuring things like atomic nuclei, where the concept of "really, really small" takes on a whole new meaning. It's been largely replaced by the femtometer, but physicists still use it occasionally when they want to confuse undergraduates.
