The Slide Rule
The Slide Rule
The Slide Rule The slide rule is mechanical device used by mostly engineers and scientists for fast and accurate multiplication, division, to find roots and powers, and other simple math problems. It consists of a fixed section with upper and lower parts marked with different logarithmic scales, a center part that slides between the parts of the fixed section and is also marked with scales, and a clear cursor that can be moved to help align the scale marks. The slide rule has almost been totally
