The Evolution of Calculators: From Desktops to Pockets
Calculators, once large and heavy machines, have come a long way since their inception. This journey of transformation began in the early 1960s, leading to the compact handheld devices we use today.
The first solid-state electronic calculators were developed in the early 1960s, marking the beginning of the calculator era. These were large, heavy machines, introduced around the end of 1961. One of the pioneers in this field was Sharp, who introduced the first near-pocket-sized calculator, the EL-8, in January 1971.
A significant turning point came in early 1971 with the development of the Mostek MK6010 integrated circuit, the first "calculator on a chip." This advancement enabled much smaller, hand-held calculators. One of the first calculators to use this technology was the Busicom LE-120A "HANDY," considered the first truly pocket-sized electronic calculator.
The 1970s saw rapid advancements in integrated circuit technology, leading to a significant drop in the size and price of calculators. By 1972, Casio released Japan’s first scientific calculator, the fx-1, expanding calculator capabilities to handle advanced formulas beyond basic arithmetic.
The development of graphing calculators was another significant milestone. Casio later developed the world’s first graphing calculator, the fx-7000G, further advancing calculator functionality for education and complex mathematical visualization.
Key companies involved in this evolution include Sharp, Busicom, Mostek, Pico Electronics, General Instrument, Texas Instruments, and Casio. Canon also developed the first handheld calculator for commercial use in 1970.
Modern calculators can perform complex scientific and graphing calculations, and some use computer languages and are programmable according to the user's needs. Additionally, solar cell technology became cheap and efficient enough to use in consumer electronics by the late 1970s, and by the 1980s, most manufacturers of simple calculators were using solar cells.
Graphing calculators are often a requirement for high school calculus and trigonometry courses. Online calculators also have practical applications, ranging from weight-loss calculators to college loan and mortgage calculators, conversion calculators, and carbon footprint calculators.
In the realm of ecologically sound components, some companies are exploring more efficient and recyclable power sources, and even using materials like recycled cellular phones in their manufacturing.
Despite the advancements in calculator technology, some argue that relying too heavily on calculators can lead to the loss of true mathematical ability. This debate continues, with some instructors still not allowing calculators in lower-grade mathematics courses to ensure students truly understand mathematical concepts and learn problem-solving techniques.
In conclusion, the timeline of the development of calculators includes key milestones for both desktop and handheld models, along with the main companies involved. From large desktop machines to compact handheld devices, this evolution was made possible through integrated circuits and display technology improvements.
