"We went to the moon with slide rules"
Norman Chaffee (NASA engineer)
Then the HP-35 calculator came in 1971, and slide rule has disappeared.
Almost 40 years after we will go to the moon soon again.
So take the slide rule with you. Just in case ... on IPhone.
This application for Slide Rule has 12 scale configuration, and allows multiplication, division, sines, tangents, roots, squares, logarithms and more. Help on "how to use" is also available. Simple to understand and fun to use. Easily scroll the top and the bottom rule, middle rule and slider. Easy to navigate and fast to learn.
