Bill Nye’s appearance in the Maverick Speakers Series in March not only enthralled the nearly 2,700 attending the free event, it also roused the Twitter universe. After his speech at a packed Texas Hall, tweets like “one of the best days of my life” and “amazing performance” saturated the popular social networking site. Nye, whose Bill Nye the Science Guy TV show won numerous Emmy awards, told audience members that they have the power to shape the future. “This is the only world we have,” he said. “We can’t mess this up.” The 2011-12 Maverick Speakers Series lineup will be announced in August.
