What is a Simple Example of an Application of Mechanical Computers and Its Advantages Over Electronic Computers?
During my studies, I had the opportunity to use both mechanical calculators and electronic calculators. My journey with a basic mechanical semi-professional calculator was quite enlightening, providing a comparison with the LaTeX-equipped HP45, a true technological marvel of its time. This article explores a simple example of a mechanical computer's application and highlights the advantages it held over its electronic counterparts.
A Simple Example: Square Root Calculation with a Mechanical Calculator
A common application of a mechanical calculator is performing square root calculations. Let's take a look at a simple example: finding the square root of 256.
First, press the root button on the mechanical calculator. Then, enter the number 256. Finally, read the result displayed, which should be 16.This process is considerably more manual than the operation of an electronic calculator, but it illustrates the basic functionality of a mechanical computer.
The Advantages of Mechanical Calculators Over Electronic Calculators
When comparing a mechanical calculator like the one I had to an electronic calculator like the HP45, the differences in advantages become more apparent.
1. Size and Portability
The mechanical calculator I used was significantly larger and heavier than the HP45. However, size and weight were not always drawbacks, especially in the context of a mechanical calculator.
2. Noise and Dependence on Power
A notable drawback of the mechanical calculator was the mechanical noise it produced, which could disrupt the work of others, particularly in a classroom setting. Additionally, the mechanical calculator required a power source, which was provided by a crank. In contrast, the HP45 was incredibly compact, ran on batteries, and produced no noise.
3. Mathematical Functions and Speed
My mechanical calculator could perform simple operations such as square roots and had mechanical memory features. In comparison, the HP45 was a marvel of technology, offering a 1/20th of the volume, 1/100th of the weight, 5 times the speed, and at least 6 times the mathematical functions, including sine and trigonometric functions.
Personal Experiences with Mechanical and Electronic Calculators
During my time, the mechanical calculator was not as popular as the electronic calculator. I had to pay 1400 DM for the HP45, which was equivalent to two times my monthly salary, making it an expensive but worthwhile investment. Despite its price, the HP45 brought me luck, particularly when I failed an exam and had to retake it.
In the retake, I used the HP45 to achieve a first-place outcome, finishing within the allowed time and with the best numerical results. My professor marveled at the speed and efficiency of the device, saying that a student had used it to type and perform calculations with incredible dexterity. The success of the mechanical calculator in this scenario underscored its value in precision and speed.
While the mechanical calculator had its limitations, such as generating noise and requiring a power source, it also provided an interesting counterpoint to the robust and versatile HP45. In some environments, the mechanical calculator's simplicity and lack of dependence on electricity made it a viable alternative. However, in the overall comparison, the HP45's advantages in terms of size, speed, and functionality made it the clear winner for many applications.
