Bill Nye “The Science Guy” is appearing at the Main Library of Cincinnati and Hamilton County on Sunday, Nov. 22, to give a brief talk and sign copies of his latest book, “Unstoppable: Harnessing Science to Change the World,” which addresses climate change.

After earning a degree in mechanical engineering and working a stint at Boeing, William Sanford Nye, otherwise known as the “Bill Nye the Science Guy,” became well known in popular culture as host of the PBS/Disney show of the same name during the 1990s. His bow tie has been a Nye trademark ever since.

After the show came to an end in the late 1990s, Nye continued to be a science educator via the entertainment industry (an “edutainer”), whether it was playing science teachers in movies, doing technical consultations on TV shows or hosting series on the Discovery Channel.

Nye’s influence is not always deliberate. The creators of the math-based crime drama “Numb3rs” which ran on CBS from 2005 to 2010, was inspired by one of Nye’s lectures. Nye would be a semi-frequent guest star on the show.

In 2005, Nye would host another series on PBS, “The Eyes of Nye.” Aimed at an older audience, “The Eyes of Nye” discussed issues such as genetically modified foods and climate change.

It is perhaps this latter issue that has turned Nye into an unlikely, latter-day culture warrior. He has not only spoken out on the danger of climate change (in his book and, most famously, on YouTube) but also criticized creationism and the attacks on Planned Parenthood.

In addition to “Unstoppable: Harnessing Science to Change the World,” Nye also published “Unstoppable: Evolution and the Science of Creation,” in 2014.
