Join us on Wednesday, September 9 at 5:30 pm as we observe the 25th anniversary of the tragic destruction of the World Trade Center with a free to the public special presentation by Bob Rollings, a retired engineer and high school science teacher from Floyd County.

Bob is a wonderful storyteller and has used his talents at the Carnegie Library Cultural Arts Center to speak on a number of science and history topics including Edwin Hubble and the Hubble Telescope, the fiery end of the German airship, the Hindenberg, and a more personal remembrance of his Armenian grandmother during the genocide that occurred in Turkey and Armenia during the early part of the 20th century.

This program will explore the seismic analysis and structural behavior of the World Trade Center during the events of 9/11, using engineering principles to help explain what happened and why. We’ll examine how the buildings responded to extreme forces, how structural systems behaved under extraordinary conditions, and what engineers have learned from studying the collapses.

Designed for a general audience, this presentation goes beyond the headlines to make the science understandable and meaningful. Whether you have a background in engineering or simply want to better understand the events of that day, you’ll gain a new perspective on the remarkable complexity of the World Trade Center structures and the lessons their collapse left for the engineering community.
