Study Notes
Pre-Mechanical or Dark Age (3000 BC – 1450 AD)
- This era was characterized by the use of simple tools for calculations, such as the abacus.
- The abacus was made of beads on rods, and people moved the beads to perform calculations.
Mechanical Age (1450 – 1940)
- This era saw the development of mechanical calculators like the slide rule and Napier's bones.
Slide Rule
- It was a hand-operated mechanical calculator consisting of slidable rulers for evaluating mathematical operations.
Napier's Bones
- It was a small machine that contained ten rods made of bone, wood, or metal.
- It was used for multiplication and division
Electromechanical Age (1930 – 1940s)
- This period introduced electromechanical devices like Charles Babbage's Difference and analytical Engine and Harvard Mark I.
- These devices used switches and relays to perform calculations.
Charles Babbage's Difference and analytical Engine
- Charles Babbage, a renowned inventor, built some of the first mathematical machines.
