In July 1993, The New Yorker published a cartoon by Peter Steiner that depicted a Labrador retriever sitting on a chair in front of a computer, paw on the keyboard, as he turns to his beagle companion and says, “On the Internet, nobody knows you’re a dog.” Two decades later, interested parties not only know you’re a dog, they also have a pretty good idea of the color of your fur, how often you visit the vet, and what your favorite doggy treat is.

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.
