8 Data Intensive Science: Knowledge Gap doubling t 1.5 yrs Large digital sky surveys are becoming the dominant source of data in astronomy: ~ TB/survey, ~ sources/survey, many wavelengths CCDs Glass An exponential growth in data quantity driven by detector technology; but our understanding of the universe increases much more slowly!
