The Evolution and Impact of the Calculator: From Enormous Machines to Portable Devices

The video discusses the evolution of calculators, starting with Texas Instruments' groundbreaking product in 1967. Initially, calculators were large and costly, but the first portable version revolutionized numerical work. Despite development challenges, including creating a compact power source, the project succeeded after 18 months. Today, calculators are ubiquitous in education, and their development paved the way for other portable technologies like computers. Modern calculators use long-life batteries or solar cells for power.
