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 ...

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 research team has developed a theoretical algorithm to accurately calculate the average distance traveled by low-energy/low-speed electrons without energy loss that are sensitive to the surface ...

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 ...
