If Excel is not using threads efficiently, calculations may take a long time to complete. Learn how to speed up calculating threads in Excel.

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 ...

Are you impressed when NASA manages to calculate the time and speed of a rocket's trajectory? A new study from the University of Oslo shows that your brain has a "nerd center" capable of even more ...

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 ...

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.

Swimmer Eric Shanteau placed third in the 200-meter breaststroke at the U.S. Olympic trials with a time of 2:10.05. This gives him an average speed of 1.538 m/s. Of course, this wasn’t his speed the ...

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) ...

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 ...
