COMSTOCK PARK, Mich. — Meteorologists all over the world use a wide variety of instruments to measure things like temperature, air pressure, humidity and a host of other variables. In Tuesday's ...

You might think that if you have a need to measure the speed of a projectile that is too fast for your high-speed camera, you would have to invest in some significantly expensive equipment. That was ...

When Galileo's name comes up, most people think about his contributions to observational astronomy. However, he did lots of other stuff including investigating the speed of light. During his time, ...

Scientists have demonstrated the fastest distance measurement so far. The researchers demonstrated on-the-fly sampling of a gun bullet profile with micrometer accuracy. The experiment relied on a ...

The motion of any object is relative. On Earth we tend to ignore that, because the vast background of the ground gives us a seemingly fixed and absolute frame of reference. Sitting comfortably at our ...

Measuring the velocity field of a fluid flow, such as air or water, allows for greater feedback and control, something that could boost the performance and fuel-efficiency of aircraft. A research ...

Imagine living sometime around the early 1600s. You're standing on the deck of a wooden ship. The wind's biting, the sky's endless. And your captain's yelling, "Drop the log!" Back then, before sonar ...

No boat is perfectly symmetric or at maximum/minimum tolerances when you first purchase it. The closer you can get it to perfect, the better it will sail. To begin, you need to take some accurate ...

It also has an easy-to-see LED display and a well-designed app.
