Abstract
Shannon entropy is often considered as a measure of uncertainty. It
is commonly believed that entropy is a good measure of how many guesses it
will take to correctly guess a single value generated by a source. This belief is
not well founded. We summarise some work in this area, explore how this
belief may have arisen via the asymptotic equipartition property and outline a
hands-on calculation for guesswork asymptotics.
