Using WiFi to see through walls

British engineers from University College London have developed a passive radar system that can see through walls using the WiFi signals generated by wireless routers and access points.

The passive radar process is actually quite simple. In any space that has WiFi, you are constantly being bombarded by 2.4GHz and 5GHz radio waves. When these waves hit a moving object, their frequency is altered (the Doppler effect). By carefully “sniffing” the WiFi signals, Woodbridge and Chetty are able to reconstruct an image any objects or humans that are moving on the other side of the wall.

Advocates of 'cliodynamics' say that they can use scientific methods to illuminate the past. But historians are not so sure.

Turchin has been taking the mathematical techniques that once allowed him to track predator–prey cycles in forest ecosystems, and applying them to human history. He has analysed historical records on economic activity, demographic trends and outbursts of violence in the United States, and has come to the conclusion that a new wave of internal strife is already on its way1. The peak should occur in about 2020, he says, and will probably be at least as high as the one in around 1970. “I hope it won't be as bad as 1870,” he adds.

Cliodynamics is viewed with deep scepticism by most academic historians, who tend to see history as a complex stew of chance, individual foibles and one-of-a-kind situations that no broad-brush 'science of history' will ever capture.

"This is a book about science, technology, and love," writes Sherry Turkle. In it, we learn how a love for science can start with a love for an object—a microscope, a modem, a mud pie, a pair of dice, a fishing rod. Objects fire imagination and set young people on a path to a career in science. In this collection, distinguished scientists, engineers, and designers as well as twenty-five years of MIT students describe how objects encountered in childhood became part of the fabric of their scientific selves. In two major essays that frame the collection, Turkle tells a story of inspiration and connection through objects that is often neglected in standard science education and in our preoccupation with the virtual.
