The method used to generate the digits, a pair of 555 timers sending pulses through linear-feedback shift registers, would at best be considered pseudo-random.

That means that even if some enemy understands everything about how the random number generator works, they still can’t predict the outcome.

A perfectly provable random number generator is the bedrock of good cryptography. This scientist wants to make one.
