The age of the universe is about 5 X 10^17 seconds; the shortest light pulse produced in a laboratory (1990) lasted for only 6 X 10^15second. Identify a physically meaningful time interval approximately halfway between these two on a logarithmic scale.

Well, log10(5x10^17) is 17.something and log10(6x10^15) is 15.something  so you need to look somewhere around log10(x) = approximately.... halfway between those two. +1 seems to be more numerically accurate, so a period of time of the order of 10 seconds but greater, while still less than, 100. After a minute's thought though, I'd just go for 0 and say that a second sort of fits the bill.

hmmm. well, the book says 55 seconds. I can't seem to figure out how the authors arrived at that answer. I suppose it is semiirrelevant. I'll just go with 1.5 minutes. bye bye problem...

You're just trying to find the halfway point between those two daft numbers. Log of the positive one is 17.69; log of the ve one is 14.22. Halfway between those is 1.73. 10^1.73 is 54odd. So do we create a new interval of time or do we opt for a minute or a second? I would go with the second but, hey, what do I know?
