Solve : 40 Years of the Mouse?

1.	Solve : 40 Years of the Mouse?
Answer» http://www.pcworld.com/article/155353/article.html?tk=nl_cxasld A celebration of Douglas Engelbart's indomitable, ever-evolving pointing device on the 40th anniversary of its public debut. On December 9, 1968, Stanford Research Institute scientist Douglas Engelbart demonstrated his unique invention--the computer mouse--for the first time in public. It took another DECADE and a HALF for it to catch on, but once it did, computing was never the same. And today, it's hard to imagine using a desktop or laptop computer without a mouse (or one of its latter-day substitutes such as the touchpad). In celebration of this anniversary, Technologizer's Harry McCracken looks at some of the mightiest mice of the past four decades. Above is Engelbart's first prototype mouse (held by its inventor). Note the square shape, hand-crafted wood case, and giant WHEEL inside. The part of this little beast that most resembles a modern mouse is the tail-like cord that gave it its name–though many mice do AWAY with that today, of course.So.....Congratulations!
