The history of mistress tangent

The Origin of the Mistress Tangent

The mistress tangent is a popular term used in mathematical circles, and its origins are hotly debated. Some believe it dates back to the early days of calculus, when Isaac Newton and Gottfried Leibniz were vying for credit for developing the field. The story goes that one of Newton’s students, John Wallis, made a mistake in his calculations and inadvertently created the first mistress tangent.

This theory is supported by the fact that the term “mistress tangent” does not appear in any of Newton’s or Leibniz’s published works. It is possible that the term was coined by Wallis himself, or that it was used informally among Newton’s students before being coined.

Other historians believe that the term originated in the 19th century, when women began to enter the field of mathematics in greater numbers. This theory is supported by the fact that the first known use of the term “mistress tangent” is in an 1873 article in The Quarterly Journal of Pure and Applied Mathematics. The article, written by Augustus De Morgan, uses the term in a pejorative way, describing a female student who distracts her male classmates with her “undue familiarity.”

It is likely that the term “mistress tangent” was first used in a joking or derogatory manner, but over time it has come to be used simply to refer to a curve that approaches a line but does not touch it. Whether its origins are in the 17th century or the 19th, the mistress tangent remains a useful and evocative term in mathematics..Visit Them

The different mistress tangent styles

A mistress is a relatively long, thin metal or composite rod with a pointed end, usually with a collared grip, used as a lever to exert torque on a nut or bolt in order to tighten or loosen it. In mechanics, a simple machine consisting of a lever mounted on a fulcrum; a more general term for any device that amplifies force.

There are three general mistress tangent styles:

The American or offset style in which the handle is set at an angle to the shank.

The European or in-line style in which the handle and shank are in line.

The Offset/American style is more popular in the United States, while the in-line/European style is more popular in Europe and Asia.

The main difference between the two styles is ergonomics. An offset/American style mistress is easier to use when the bolt is in an offset/non-inline position, such as when the bolt is in a corner or when the user’s hand is not in line with the bolt. An in-line/European style mistress is easier to use when the bolt is in an in-line/non-offset position, such as when the bolt is in the middle of a board or when the user’s hand is in line with the bolt.

There are also variations of the in-line/European style, such as the Japanese style, in which the shank is offset from the handle, and the Swiss style, in which the handle is offset from the shank.

No matter what the style, a mistress is an essential tool for any mechanic or do-it-yourselfer. It is a simple yet versatile device that can be used to loosen or tighten a variety of nuts and bolts.
