Nomogram

A Nomogram, also known as a nomograph, is a graphical calculating device, a two-dimensional diagram designed to allow the approximate graphical computation of a mathematical function. The field of nomography was invented in 1884 by the French engineer Philbert Maurice d'Ocagne and used extensively for many years to provide engineers with fast graphical calculations of complicated formulas to a practical precision.

History

The history of nomogram dates back to the late 19th century. The French engineer Philbert Maurice d'Ocagne is credited with inventing the field of nomography in 1884. Nomograms were widely used by engineers and other professionals for many years, providing them with fast graphical calculations of complicated formulas to a practical precision.

Design and Use

The design and use of nomogram involves creating a two-dimensional diagram that allows for the approximate graphical computation of a mathematical function. This is achieved by aligning a straight edge at the desired values on the scales and reading the corresponding result.

Types of Nomograms

There are several types of nomograms, including the alignment chart, the parallel coordinates, and the picket fence nomogram.

Applications

Applications of nomogram can be found in various fields such as engineering, mathematics, and medicine. In medicine, for example, nomograms are used to calculate body surface area, determine dosage of medication, and predict the outcome of certain medical conditions.
