Inside the capacitor, the terminals connect to two metal plates separated by a non-conducting substance, or dielectric. You can easily make a capacitor from two pieces of aluminum foil and a piece of paper. It won’t be a particularly good capacitor in terms of its storage capacity, but it will work. In theory, the dielectric […]

Cell-phone Frequencies In the dark ages before cell phones, people who really needed mobile-communications ability installed radio telephones in their cars. In the radio-telephone system, there was one central antenna tower per city, and perhaps 25 channels available on that tower. This central antenna meant that the phone in your car needed a powerful transmitter

Video glasses aren’t a new idea in the high-tech world, in which they’ve been known as a kind of head-mounted display (HMD). They’re also called personal media viewers. No matter what you prefer to dub them, you can’t deny that HMD technology has improved tremendously in the past couple decades. When first widely introduced to

Why Test? Alcohol intoxication is legally defined by the blood alcohol concentration (BAC) level. However, taking a blood sample in the field for later analysis in the laboratory is not practical or efficient for detaining drivers suspected of driving while impaired (DWI) or driving under the influence (DUI). Urine tests for alcohol proved to be

(Phys.org) —For sea turtle hatchlings struggling to reach the ocean, success may depend on having flexible wrists that allow them to move without disturbing too much sand. A similar wrist also helps a robot known as “FlipperBot” move through a test bed, demonstrating how animals and bio-inspired robots can together provide new information on the principles governing locomotion on granular surfaces.

From the T-101 to Data from Star Trek, humans have been presented with the fictional dilemma of how we empathize with robots. Robots now infiltrate our lives, toys like Furbies or robot vacuum cleaners bring us closer, but how do we really feel about these non-sentient objects on a human level?
Augmented-reality applications — software that overlays a level of digital information on top of the physical world around us — have brought us more data. With an augmented-reality app on your smartphone, you might be able to hold your phone’s camera up to capture the image of a city street. Looking at the screen, you
