When was the last time you saw an engineer portrayed glamorously in a film—or, for that matter, in any form of popular culture? Right. Let’s face it: The unflattering stereotypes persist, and they’re tired. They’re also out of touch with reality. Just consider the five engineers we profile here.

Before Ships Used GPS, There was the Fresnel Lens

This bright idea revolutionized lighthouses and saved lives

Ships today use satellite-based radio navigation, GPS, and other tools to prevent accidents. But back at the beginning of the 19th century, lighthouses guided ships away from rocky shores using an oil lamp placed between a concave mirror and a glass lens to produce a beam of light.

The mirrors were not very effective, though, and the lenses were murky. The light was difficult to see from a distance on a clear night, let alone in heavy fog or a storm.

Novel devices known as photonic topological electromagnetic circuits may one day support 5G wireless broadband networks and advanced radar systems, a new study finds.

Topology is the branch of mathematics that explores what features of shapes may survive deformation. For instance, an object shaped like a doughnut can be deformed into the shape of a mug, so that the doughnut’s hole forms the hole in the cup’s handle. However, the object couldn’t lose its hole without changing into a fundamentally different shape.
