Detailed explanation-1: -NASA engineers used slide rules to build the rockets and plan the mission that landed Apollo 11 on the moon. It’s said that Buzz Aldrin needed his pocket slide rule for last-minute calculations before landing.

Detailed explanation-2: -William Oughtred simplified things further with the slide rule by taking the two Gunter’s lines and sliding them relative to each other thus eliminating the dividers.

Detailed explanation-3: -About 1622, William Oughtred (Figure 1, right), an Anglican Minister, today recognized as the inventor of the slide rule in its actual form, by placing two such scales side by side and sliding them to read the distance relationships, thus multiplying and dividing directly. He also developed a circular slide rule.
