After 10 years I think my absence of a mathematical education has finally come to hurt me in a programming setting. I need to calculate the distance between two points on Earth using a Great Circle ...

Units of speed are always a unit of length per unit of time. Different units of length and time may be chosen depending on the situation. This makes it easier to read the measurements. For example, ...

We can use formulas to model real-life situations. For example, the formula for calculating speed is speed = distance ÷ time. It is possible to calculate the speed, distance or time if you have the ...

Last month, I closed this column with a script that can return latitude/longitude values for two addresses, with the intent ultimately being to have the script calculate the distance between those two ...

Most fiber optic transmission systems are designed to work with one of two types of fiber optic cable: single-mode or multimode. The glass core in the center of single-mode fiber is thinner than in ...

As the need for bandwidth rises and the cost of fiber optics drops, fiber is beginning to replace copper cable in many network topologies. And the cost of fiber is expected to be on par with copper ...

Coupling is the transfer of energy which happens in the space between the heating portion of the coil and the workpiece. Thus, coupling distance is how big a space must be to balance manufacturing ...

Cepheid variable stars exhibit regular pulsations whose period directly correlates with their intrinsic brightness (absolute luminosity). The Leavitt law establishes this relationship between ...
