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 ...

In special relativity, the speed of light is the ultimate speed limit to the universe. Every single moving object in the universe is constrained by that fundamental limit. This isn’t something like ...

A series of new animations by a NASA scientist show just how zippy - and also torturously slow - the speed of light can be. Light-speed is the fastest that any material object can travel through ...

The transcript below has been edited for brevity and clarity. FTAV: In Trading at the Speed of Light you describe high-frequency trading (HFT) as both Einsteinian and mundane. What do you mean?
