the slide rule
Two mathematical innovations in the 17th Century were the slide rule and algorithms.
The Slide Rule
Two examples are abacus and slide rule
You could use it to find the answer to basic mathematical problems. It's like a simple, mechanical calculator.
Translation is sliding without turning. You can slide left or right, or up or down (or any combination).
A slide rule is a mathematical tool used for various calculations, including multiplication, division, roots, logarithms, and trigonometric functions. By sliding the scales relative to each other, users can quickly perform complex calculations without the need for batteries or electronic devices. While largely replaced by calculators, slide rules are still appreciated for their educational value in understanding mathematical concepts and for their historical significance in engineering and science.
Slide rules are generally more compact and easier to use than Napier's bones, allowing for quicker calculations without the need for physical manipulation of separate rods. They provide a continuous scale for various functions, enabling rapid multiplication, division, and more complex operations. Additionally, slide rules can be more versatile, accommodating a range of mathematical functions in one device, whereas Napier's bones are limited to specific calculations. Overall, the slide rule's design enhances user efficiency and convenience in mathematical operations.
William Oughtred was the inventor of the Slide Rule which allowed mathematical operations such as multiplication and division to be calculated by reading values from graduated scales. Slide rules were still commonly used in the 1970's and early 1980's but with the invention of modern electronic calculators, the use of the slide rule has declined.
Napier's Bones are an old name for the slide rule, a mechanical method of rapidly doing mathematical operations using logarithms expressed as a divided line.
