Beat the Heat

Of all the issues facing chip and computer designers, none is more burning than the soaring levels of power flowing through integrated circuits

11 min read

A little over a year ago, a Swedish scientist learned the hard way that laptop computers do not quite live up to their name. According to the British medical journal The Lancet, the mercifully anonymous man spent an evening writing a report, periodically shifting position to avoid heat from the machine. The next day he woke to find himself blistered in a very sensitive place. He'd been well and truly fried.

Anyone old enough to associate the word "computer" with 1950s-era images of the original UNIVAC, with its 5200 tubes cooled by water drawn from a river, probably won't be shocked by the news that a computer could inflict a second-degree burn. Indeed, the fabled machine once failed spectacularly when a wayward fish obstructed the water's flow. Nevertheless, engineers, lulled by the ubiquitous hum of their workstations' fans, can be forgiven for thinking that the heat thrown off by a computer's innards is no longer a burning issue.

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.
