In my recent post about calculating the speed of light, I mentioned Ole Roemer's calculation in 1676. The basic idea uses the orbit of one of Jupiter's moons. The orbital period is constant, but there ...

You might already know that the speed of light is 299,792,458 meters per second, but now you can confirm that number by playing kitchen scientist and melting chocolate. And then eating the results.

Two Spanish scientists have designed an equation that provides a highly accurate estimate of an individual's speed based on stride length. They used data from professional athletes and walking and ...

If you just celebrated Easter, you might have some stale marshmallow Peeps lying around the house. And if you want to avoid eating those Peeps, they are the perfect material for a science experiment ...

A team from Los Alamos National Laboratory was able to use the microphone and a laser to calculate the speed of sound on Mars, and it's surprisingly slow. Share on Facebook (opens in a new window) ...

When dark matter is the most pervasive substance in the universe, it's important that we know how quickly it can move. Thankfully, Syracuse University scientists may have just found that speed. By ...
