Google, the company, entered this world in 1998. I'm not sure how long it took for Google , the verb, to follow — but I do know that millions of people engage in that particular activity many, many times each day. For half of all Internet users worldwide, Google is the portal to the collected and digitized wisdom (and folly) of humanity. Google's search engine has changed how we conduct research, plan vacations, resolve arguments, find old acquaintances, and check out potential mates.
The right stuff kicks in at T-minus 31 seconds. As the 120-ton space shuttle sits surrounded by almost 4 million pounds of rocket fuel, exhaling noxious fumes, visibly impatient to defy gravity, its on-board computers take command. Four identical machines, running identical software, pull information from thousands of sensors, make hundreds of milli-second decisions, vote on every decision, check with each other 250 times a second. A fifth computer, with different software, stands by to take control should the other four malfunction. At T-minus 6.6 seconds, if the pressures, pumps, and temperatures are nominal, the computers give the order to light the shuttle main engines -- each of the three engines firing off precisely 160 milliseconds apart, tons of super-cooled liquid fuel pouring into combustion chambers, the ship rocking on its launch pad, held to the ground only by bolts. As the main engines come to one million pounds of thrust, their exhausts tighten into blue diamonds of flame.
