We know that measuring the speed of light with an Arduino is possible. It’s just that the implementation is hard. [Udo] hit upon the idea of pulsing a laser pointer and measuring the time of the ...

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 ...

Many measurements start with sensors, be they temperature, strain, light, position, or other physical properties. Accurately measuring the distance to and speed of an object has challenges relating to ...

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 ...

Einstein is most famous for general relativity, which is really a theory of gravity. But his theory of special relativity has been just as important. Special relativity is all about how to interpret ...
