Pehr-Georg and Edvard Scheutz’s Differential Engine Explained 

The Differential Engine of Pehr and Georg was an extended, smaller, and better version of Charles Babbage’s Differential Engine. The Differential Engine was invented in 1853.

Differential Engine: History

Pehr-Georg Scheutz is most known for creating the Differential Engine, the first operational and commercially accessible difference engine. The Difference Engine was first proposed in 1837, but he did not complete it until 1843.

Differential Engine: How It Worked

The Differential Engine worked on the principal and computational techniques of Babbage’s difference engine and described, in a relatively non-technical fashion, the working of the machine and Babbage’s concept of mechanical notation.

The calculation of a table was carried out in four stages:

– The start values of the table in question were calculated manually. – The number wheels in the calculating unit were set at the start values with the help of a special tool.

Differential Engine: Historical Significance

The machine could handle numbers of 15 digits and tabulate functions with 4 orders of differences (the fourth being constant) and print out results, rounded off to eight digits, on molds from which metal printing plates could be cast.
