Before calculators fit in your pocket—and long before anyone asked a phone for the answer—there was the slide rule: the essential tool of every Brooklyn Tech engineer. No batteries required, just skill, focus, and a steady hand. 

For generations of Technites, the slide rule was more than an instrument; it was a rite of passage. In Tech classrooms, it turned complex equations into elegant solutions and helped shape the analytical minds that went on to build, design, and innovate across every field. 

A six-foot-long classroom demonstration slide rule, similar to the one pictured here with its owner, Floyd Warkol '65, a Titan of Tech awardee, stands as a larger-than-life reminder of that era. It’s equal parts craftsmanship, nostalgia, and intellectual grit—a true artifact of Brooklyn Tech’s legacy of excellence.
