They are mathematics heroes who should you respect. Imagine what would this world without a calculator. Mathematicians at this time, if given the choice to use a calculator or not, would choose to use a calculator. Moreover we as a student.
Along with the emergence of a pencil and paper, especially in Europe, the abacus lost popularity. After almost 12 centuries, another finding emerged in terms of computing machines. In 1642, Blaise Pascal (1623-1662) who was 18 years old, found what he called a numerical wheel calculator (numerical wheel calculator.)
He is used to help his father make tax calculations. Square box brass or calculating machines were found, called the Pascaline. Pascaline uses eight toothed wheel to add numbers to eight digits. This tool is a calculator tool based on the number ten. The downside of this tool is only limited to the sum.
After Pascaline invention, appears calculator that has multiple functions. The device was discovered in 1694, a German mathematician and philosopher, Gottfred Wilhem von Leibniz (1646-1716).
In 1820, mechanical calculators become popular. Charles Xavier Thomas de Colmar find a machine that can perform four basic arithmetic functions, addition, subtraction, multiplication, and division. With his ability, arithometer widely used until World War I.
Until finally, calculators continue to be developed and can be counted in large numbers. Vannevar Bush created a calculator to solve differential equations in 1931. This machine could solve complex differential equations that have been considered complex.
The machine was very large and heavy as hundreds of serrations and the shaft is required to perform calculations. In 1903, John V. Atanasoff and Clifford Berry tried to make a computer that applied Boolean algebra electricity, mathematical calculations that can be expressed as true or false.
Now, a calculator made in the form of a simpler, easier to carry. Even the phone can be a calculator. |
