K&E produced its last slide rule, which it presented to the Smithsonian Institution. A common method of performing mathematical calculations for many years, the slide rule became obsolete with the invention of the computer and its smaller, hand-held sibling, the calculator.
Since opening at the end of 2013, over 5,000 children have visited the Centre. These children deserve a space which is engaging and instructive, where they can feel a sense of adventure, exploration and surprise!
