We know that rnorm() computes the output from an internal seed it keeps as a state variable. The rest are computations and, therefore, it allows up to compute the output if we guess the seed.
According to the CRAN package description, the random package in R provides an interface to the true random
number service provided by the random.org website. It operates by sampling atmospheric
noise via radio tuned to an unused broadcasting frequency
together with a skew correction algorithm due to John von
Neumann (which I don't know what it means yet). So if you are ever interested in improving your random numbers to better perform your simulations, bear this package in mind.
