What is the slide rule on a pilot?
A slide rule is a circular scale that either surrounds the watch face as a bezel or is located on the inner flange. It can be rotated in either direction, allowing you to perform various calculations related to time, speed, distance, and conversions. They are a valuable aid for performing quick calculations on the fly. Slide rules are now mainly found in museums and collections, as their practical use has been replaced by modern electronic calculators and computer software.A slide rule is a hand-operated mechanical calculator consisting of slidable rulers for conducting mathematical operations such as multiplication, division, exponents, roots, logarithms, and trigonometry. It is one of the simplest analog computers.With this rotary slide rule, a wide variety of computations are possible, including ordinary multiplication, division, computation of flight speed, fuel consumption, and unit conversion.Slide rules are still commonly used in aviation, particularly for smaller planes. They are being replaced only by integrated, special purpose and expensive flight computers, and not general-purpose calculators.
What is the must slide rule?
Must a runner slide into home plate? No. Little League does not have a “Must Slide” rule for a runner sliding into home or any other base. However, any runner is out when not making a physical attempt (to slide) in order to avoid a collision while a fielder who has the ball and is waiting to make the tag. Comment: There is no “must slide rule. The rule is, “slide, or attempt to get around. The key in this situation is, “the fielder has the ball and is waiting to make a tag. If the fielder (any fielder, not just the catcher) does not have the ball, and there is a collision, you CANNOT call the runner out.
What is the first slide rule?
In 1632 another English mathematician, William Oughtred, designed the first adjustable logarithmic rule; as shown in the photograph, it was circular. Oughtred also designed the first linear slide rule, although the familiar inner sliding rule was invented by the English instrument-maker Robert Bissaker in 1654. William Oughtred (born March 5, 1574, Eton, Buckinghamshire, England—died June 30, 1660, Albury, Surrey) was an English mathematician and Anglican minister who invented the earliest form of the slide rule, two identical linear or circular logarithmic scales held together and adjusted by hand.The slide rule was invented by William Oughtred in the 1600’s, but only began to be widely used in the mid 1800’s after a French artillery officer named Amedee Mannheim developed a version that became popular among engineers.William Oughtred, the inventor of the slide rule, was born at Eton, Berkshire, circa 1574. His father appears to have been a junior master at Eton College, which is where Oughtred went to school.
What is the most beautiful slide rule?
FABER-CASTELL 2/83N slide rule is considered by some to be the finest and most beautiful slide rule ever made. Faber-Castell 2/83N Novo-Biplex A May 2006 article in Scientific American stated that this rule might be the most beautiful slide rule ever made. If not, it cannot be far from it!
