Determine how many floating-point operations a supercomputer can perform in a human lifetime. Use a value of s as the time for a single floating-point operation in a supercomputer and a value of s for a human lifetime.
To the nearest order of magnitude, how many human generations have existed between the year 0 AD and the year 2000 AD? Use a value of s for an average human lifetime and assume that a generation is one-third of a lifetime.
