A software routine that produces a random number. Used in applications such as computer games and cryptographic key generation, random numbers are easily created in a computer due to many random ...

“This is a marvelous step” toward more efficient random number generation, says Rajarshi Roy, a physicist at the University of Maryland in College Park who was not involved in the work. Random number ...

Quick! Think of a number between 1 and 10…was it 7? If it was, don't feel too bad, as human brains are notoriously bad at both true randomness and understanding probability. Even if you're too ...

Hackers love random numbers, or more accurately, the pursuit of them. It turns out that computers are so good at following our exacting instructions that they are largely incapable of doing anything ...

Researchers have built the fastest random-number generator ever made, using a simple laser. It exploits fluctuations in the intensity of light to generate randomness—a coveted resource in applications ...
