How do calculators work?
Calculators have evolved in a fascinating journey that takes us back to the early 1960s when the first mechanical device was introduced. This early version was a far cry from the handheld calculators we know today, with their compact size and ability to perform basic arithmetic and more complex calculations such as square root and trigonometric functions.
One of the first companies to enter the calculator business was Hayakawa Electric, now known as Sharp Corporation. They introduced the first desktop calculator, which used a cathode ray tube. However, Texas Instruments, a significant semiconductor industry player, revolutionized the calculator market by introducing the first single-integrated circuit calculator in the late 1970s. This new product significantly reduced power consumption, making calculators more efficient and less power-hungry.
Around the same time, Canon, another major player in the calculator business, introduced the Canon Pocketronic, a handheld calculator. This was the first time a calculator was small enough to be carried around easily. The Pocketronic used magnetic cards to store programs and data, a precursor to the programmable calculators of today.
In the early 1970s, calculator manufacturers began incorporating electronic components into their products, leading to the development of the scientific calculator. One of the first was the Sinclair Scientific, produced by Sinclair Radionics in partnership with General Instrument. This calculator could perform scientific notation, a significant leap from the basic arithmetic capabilities of earlier models.
National Semiconductor and Rockwell International, two leading semiconductor manufacturers, also entered the calculator market. They produced calculators with LED displays, which were easier to read than the previous liquid crystal displays.
The calculator business continued to evolve with the introduction of the graphing calculator in the late 1970s. These calculators, like the ones produced by Hewlett Packard, could plot graphs and solve equations, making them a valuable tool for students and professionals.
The New York Times reported in the early 1980s that Japanese calculator manufacturers dominated the market, with companies like Sharp Corporation and Hayakawa Electric leading the way. However, American companies like Texas Instruments and National Semiconductor were just slightly behind.
By the late 1980s, third parties began producing calculator electronics, reducing the high price of calculators and making them more accessible to the general public. This opened the calculator market to a broader range of consumer products, including personal computers.
Today, calculators are a standard tool in schools, offices, and homes worldwide. These devices have come a long way, from the slide rule to the scientific calculator, from the desktop calculator to the handheld calculator. As we look to the future, we can expect calculator manufacturers to continue innovating and improving their products, ensuring that calculators remain essential for many years.
How long do the batteries last in a basic pocket calculator, and how do you change them?
The battery life of electronic pocket calculators varies depending on usage. Still, they can last from several months to a few years on average. To change the batteries, locate the battery compartment on the back of the calculator, open it, and replace the old batteries with new ones.
