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, ...

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 ...

This one has a quick answer and a longer explanation. The quick answer is that there is no absolute point of reference that defines motion for all other objects in the Universe. All of our estimates ...

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 ...
