New Approach to Astronomy

 in the past, exploratory efforts in astronomy were constrained by the need to carefully select small samples, we can now imagine exploiting the revolution in computing and networking to:    - discover patterns revealed from analysis of statistically rich and unbiased image and/or catalog databases and from application of advanced visualization tools; and, - deepen our understanding of complex astrophysical systems through sophisticated numerical simulations with the use of advanced statistical methods erase old barriers of time and distance in carrying out modern astronomical observations 17
