There will be an app for that: making random numbers on a mobile phone. (Courtesy: Marketa Michalkova) Do you feel nervous when you make a credit-card transaction using your mobile phone? Your worries ...

A team of international scientists has developed a laser that can generate 254 trillion random digits per second, more than a hundred times faster than computer-based random number generators (RNG).

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 very important to us in this computer age, being used for all sorts of security and cryptographic tasks. [Theory to Thing] recently built a device to generate random numbers using ...

How to generate random numbers with no duplicates in Excel Your email has been sent Over the last few months, I’ve written about several of Excel’s new dynamic array functions. They’re powerful and ...

Using the inherent quantum flickering of empty space, researchers have figured out how to generate random numbers at an unprecedented rate. The record-breaking method could be used to enhance ...

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 ...

RANDOMNESS IS A valuable commodity. Computer models of complex systems ranging from the weather to the stockmarket are voracious consumers of random numbers. Cryptography, too, relies heavily on ...

Generating random numbers might seem like a trivial task, that is until the numbers need to be truly random for cryptography or security reasons. When that’s the case, it turns out that these numbers ...
