Abstract: A brief theory of work is developed. In it, the work-factor and guesswork of a random variable are linked to intuitive notions of time complexity in a brute-force attack. Bounds are given for a specific work-factor called the minimum majority. Tight bounds are given for the guesswork in terms of variation distance. Differences between work-factor, guesswork and the entropy of a random variable are pointed out, calling into question a common misconception about entropy indicating work. The... (Update)
