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 ...

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 ...

While working towards his Computing and Information Systems degree at the University of London, [Jason Fenech] submitted an interesting proposal for generating random numbers using nothing more exotic ...

Generating random lists of numbers in Excel is handy for randomizing lists, statistical sampling, and many other uses. However, Excel's random number functions are volatile, meaning they change ...

One of the pieces of equipment for the quantum random number generator in the NIST Boulder laboratories. Very little in this life is truly random. A coin flip is influenced by the flipper’s force, its ...

Whether you are generating lottery numbers or sample data for a survey, random numbers are easy to create in Excel. While true randomness is difficult to simulate with software, Excelâ s random ...

Skyrmions, tiny magnetic anomalies that arise in two-dimensional materials, can be used to generate true random numbers useful in cryptography and probabilistic computing. Whether for use in ...

Random numbers are crucial for computing, but our current algorithms aren’t truly random. Researchers at Brown University have now found a way to tap into the fluctuations of quasiparticles to ...

Strong passwords are needed to protect your electronic accounts from brute force attacks and other cyberattacks attempted by hackers. In this article, I am going to show you how you can generate a ...
