Reading a clock is one thing; really knowing the time is quite another. For everyday timekeeping needs, we use a standard known as Coordinated Universal Time, or UTC, which is derived from International Atomic Time, a consensus of more than 200 clocks that keep precise time based on the movement of electrons.
If you've ever thought it'd be cool to make your own robot but didn't because your options were Legos (ho-hum) or fabricating one from scratch (who's got the time?), listen up: RadioShack's new Vex Robotics Design System (vexrobotics.com) is the ultimate compromise. The $300 kit contains more than 500 parts, including steel plates, motors, radio receivers and a six-channel remote. What to build? That's up to you.
