How Nystrom‘s Calculator Worked – A Technical Deep Dive
The device consisted of:
- Nine inch circular brass base plate precisely engraved with curves
- Mounted movable indicator arms could slide to intersect curves
- Scales calibrated to enable complex multiplicative/additive calculations when aligned
Key Innovations
- Direct angle-based trigonometric calculations
- Isolated "processing" in calibrated plate from variable inputs in slider arms
- Mechanical sophistication enabling both multiplication/division and addition/subtraction operations
