Back in the sky over the Pacific on Friday, physics and chemistry will take over. The interceptor's three sensors--two detecting heat and one detecting visible light--all share the telescope that juts out its front end. The visible-light sensor will get the interceptor into the right neighborhood, but only the infrared sensors can guide it into its target, gently steering it with minithrusters powered by 30 lbs. of liquid rocket fuel. For the heat-detecting sensors to "see" anything, they must be chilled to -330[degrees]F using nitrogen and krypton, funneled to the sensors through...
...dream of a sensor that sounds a buzzer when a child's liquid content nears full, homes in on the nearest public bathroom and, when you get there, brakes the car to a stop in one-fifth of a second and opens the door even faster. They could call it Bladdermatic. I long for interior window surfaces chemically coated to atomize dog-slobber on contact...

...Cyrano's enthusiastic (and aptly named) ceo Steven Sunshine is to be believed, Cyranose is "seeing" in Technicolor. When properly trained, its 32-sensor Nose-Chip[TM] can sniff a particular variety of rice and tell you not only which one it is but also where it was grown. Does it smell as well as we do? Yes and no. It has trouble detecting some things to which human noses are acutely attuned--such as the stench of rotting eggs--but it can be trained to pick up others most people would never notice. There are limits, however...
