Making random numbers is a hot business in computer science. Graphics and cryptography, in particular, rely on randomness or at least randomness that’s good enough to fool users/hackers/gamers. Mostly ...

Random numbers are essential for secure cyber communications. But making truly random numbers is harder than it seems. Now scientists have devised a way to make the most random random numbers ever. A ...

Randomness is a slippery concept, defying precise definition. A simple example of a random series is provided by repeatedly tossing a coin. Assigning “1” for heads and “0” for tails, we generate a ...

Nobel Prize-winning physicist Frank Wilczek explores the secrets of the cosmos. Read previous columns here. Many summers ago, I discovered a book called “A Million Random Digits with 100,000 Normal ...

Even though rand() may be a good enough random number generator for making a video game, the patterns of random bits it spits out may not be sufficient for applications requiring truly random data.

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 ...

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 ...

What is a random number? As the term suggests, a random number is a number chosen by chance -- i.e., randomly, from a set of numbers. All the numbers in a specified distribution have equal probability ...

Computers are known to be precise and — usually — repeatable. That’s why it is so hard to get something that seems random out of them. Yet random things are great for games, encryption, and multimedia ...
