The Rule of Four was created in 2004.
The Rule of Two was created by Darth Bane, a Sith Lord in the Star Wars universe. He established this philosophy to ensure that there would only ever be two Sith at one time: a master and an apprentice. This was intended to prevent infighting among the Sith and to focus their power and ambition. Bane's Rule of Two became a foundational principle for the Sith Order in the millennia that followed.
Two mathematical innovations in the 17th Century were the slide rule and algorithms.
Side-Angle-Side is a rule used in geometry to prove triangles congruent. The rule states that if two sides and the included angle are congruent to two sides and the included angle of a second triangle, the two triangles are congruent. An included angle is an angle created by two sides of a triangle.
The slide rule was invented in the 17th century, with its development attributed to several mathematicians. The first known slide rule was created by William Oughtred in England around 1620, based on the logarithmic scales developed by John Napier. The device gained popularity among scientists and engineers for calculations before the advent of electronic calculators.
