An enormous hydraulic machine press that stamps out a pickup truck's doors in seconds... Rock crushers that pulverize 8000 tons of solid granite per hour... Giant "chain trenchers" that dig a 35-foot ditch out of solid rock... A harvesting combine that cuts, threshes and offloads 3.3 bushels of grain-- per second... and the world's largest optical telescope, the magnificent Keck Observatory, which gazes out into the ends of the universe from nearly 14,000 feet atop the island of Hawaii. Sometimes you've gotta think big.
