>Because all that progress has been made in baby steps. All science progress is 99% incremental-a tweak in design here, a bump in power there, **a goose to speed** over here, all occasionally given a huge, mind-bending boost by a theory of evolution, the unraveling of DNA, or the invention of the laser. The big developments might pull in the headlines like a black hole, but it's the constant small, day-to-day improvements that have the most immediate impact on what we do. In this chapter we'll look at some less-than-monumental ways in which computer storage-always the laggard in computing speed-has constantly improved by tids and bits.

What do you think that expression means? Searched in the dictionaries and couldn't find anything that at least remotely talked about the word *goose* as it's used in the example above.
