Computers are deterministic and are therefore predictable. Computers cannot, in and of themselves, generate truly random numbers. In the absence of outside input, computers can only create pseudo-random numbers. In the words of John Von Neumann, “Anyone attempting to produce random numbers by purely arithmetic means is, of course, in a state of sin.” A …

Java does not directly support constants. However, a static final variable is effectively a constant. The static modifier causes the variable to be available without loading an instance of the class where it is defined. The final modifier causes the variable to be unchangeable. Ex: public static final int FOUNDING_YEAR = 2001; Naming Standards for …
The Kelvin Scale is a thermometric scale used in physical science to describe the absolute temperature of an object, substance, or area. While Fahrenheit and Celsius scales measure temperature, the Kelvin Scale defines temperatures relative to an object’s thermodynamic movement. As a result, the Kelvin Scale does not use degrees, but simply a number followed …
As society is trying to slowly ween itself off of oil-dependency, the search for alternative fuels continues. One source of alternative "fuel" that already exists, however, is the electric motor. Electric motors are commonly found in vehicles, toys, and other electronic devices but there is still a campaign to improve the quality and efficiency of …
A PID (Proportional Integral Derivative) controller is a device that makes changes to a system based on current and intended settings. PID controllers are used in a wide variety of industrial control systems and are the most commonly used feedback controllers in the world. PID controllers allow users to obtain and/or maintain preferred conditions within …
