In science, we often say things like “all scientific results must be replicable.” If you have one researcher who says “I’ve measured the speed of light to be 3-million meters per second.” another ...

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 ...

Corrections & clarifications: A previous version of the story misstated a measurement of Internet speed. We know what “slow” internet is like: videos buffer, downloads lag and a single page can take ...

There’s a simple way to measure the speed of sound. It’s low tech and unimpressive, but you get to blast an air horn. How many times can you say that you’re using one for science and not sheer ...

Measuring speed with Arduino isn‘t something new, but the interesting part of this project that speed information is displayed on Flash application. Application has been built using Flex 4 and is ...

Are "internet speed tests" (like those from Ookla) a very poor measure of wireless internet performance? Are they just too crude to give a realistic appraisal of real WLAN performance?

If you’ve never seen the International Space Station in orbit, you’re missing out on something awesome. Oh, you don't have a telescope? No problem, the ISS is easily visible at night. True. It looks ...

There’s no question that educational institutions require reliable, high-speed connectivity. We’re all in agreement there. The question that arises is: How fast is fast enough? There are a number of ...

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 ...
