Think of a random number between one and ten. Most likely, you chose seven—so exactly how random was your choice? Turns out that generating a truly random number is more difficult than you might think ...

Perfect randomness sounds simple, until you try to make it. A die can be polished, balanced and rolled thousands of times. Yet, one face may still land up a little more often than the others. In daily ...
