Google Seach is fantastic. But you can't find the answers to these questions. How high are Dubai man-made islands? Will the rising sea level affects those islands? How do the Swiss make those tiny tiny gears, springs, shafts ... for the mechanical watches? In the olden days, there were no helicopters, no GPS. How did people plot the contour lines for the rugged treacherous mountainous forested area? I tried making red wine with dark red grapes. I aged it in a glass container as I didn't have the wooden barrel. End result - wine that was almost colorless. Why it is not red in color? Must I add red color dye? Is there something I can do to improve the SEARCH? Are there other questions which you can't find the answers from Google Search?
