Randomness rules the very fabric of reality. So it only makes sense that scientists have figured out how to use nature’s randomness as a tool in our mundane world. Random numbers go hand-in-hand with ...

WEST LAFAYETTE, Ind. – If you wanted a random number, historically you could do worse than to pick a sequence from the string of digits in pi. But Purdue University scientists now say other sources ...

Using a single, chip-scale laser, scientists have managed to generate streams of completely random numbers at about 100 times the speed of the fastest random-numbers generator systems that are ...

Random numbers are increasingly important to our digitally connected world, with applications that include e-commerce, cryptography, and cloud computing. Producing a large amount of truly random ...

The quest for truly random numbers is something to which scientists and engineers have devoted a lot of time and effort. The trick is to find an unpredictable source of naturally occurring noise that ...

To simulate chance occurrences, a computer can’t literally toss a coin or roll a die. Instead, it relies on special numerical recipes for generating strings of shuffled digits that pass for random ...

Your job is to create a random number generator. Your device starts with a speaker and a membrane. On this membrane will sit a handful of small, marble-size copper balls. An audio source feeds the ...

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 ...

Quantum physics can be exploited to generate true random numbers, which have important roles in many applications, especially in cryptography. Genuine randomness from the measurement of a quantum ...
