Sensor Sensibility

Have you lost your senses? You’ll find them everywhere you look. Sensors respond to external stimuli – light, sound, temperature and much else – to help us make sense (ha!) of our universe. And more are on their way. “Ubiquitous sensing” is the term that describes a world blanketed by tiny sensors: on bridges, in paint and medicine bottles, and even in our brains!

Discover where you’ll find sensors next. And, has the world’s largest detection device found the elusive particle that will help explain the universe? Where are you, Higgsy-wiggsy?

Also, out-of-this world sensors have detected a possibly Earth-like planet. What’s next for the Kepler planet-hunters?

Plus, DIY sensor kits, and, if computers can do all that, why can’t we send the odor of, say, freshly-baked bread over the Internet? The case for a smell-o-meter.
