The slide rule was invented by William Oughtred, an English mathematician and clergyman, around 1622. It was developed from the logarithmic principles introduced by John Napier. Therefore, Option B (William Oughtred) is the correct answer.
A slide rule is a mechanical calculating device that uses logarithmic scales to perform mathematical operations such as multiplication, division, roots, and powers. It became an important tool for engineers, scientists, mathematicians, and other professionals before electronic calculators became widely available.
John Napier is well known for developing logarithms, which provided the mathematical foundation for the slide rule. Gottfried Leibniz made major contributions to mathematics and helped develop the mechanical calculator known as the stepped reckoner. Blaise Pascal invented the Pascaline, an early mechanical calculator capable of performing arithmetic operations.
The slide rule remained an important calculating instrument for several centuries. Although it could not provide the same precision as modern electronic calculators, it allowed users to perform complex calculations relatively quickly using logarithmic scales.
