However, the specific invention cannot be attributed to a single individual, as similar mechanisms were used in various forms by many engineers and inventors over time.

The invention of the wheel primarily caused structural unemployment rather than frictional or cyclical unemployment. Structural unemployment occurs when advancements in technology, like the wheel, lead to changes in the labor market, rendering certain skills obsolete. As societies adopted the wheel for transportation and agriculture, jobs related to older methods became less relevant, displacing workers who had to adapt to new technologies or find new roles. In contrast, frictional unemployment involves short-term transitions between jobs, while cyclical unemployment is linked to economic downturns, neither of which is directly caused by a technological innovation like the wheel.

The electric telegraph was developed over several years in the early 19th century, with key advancements occurring between the 1830s and 1840s. Samuel Morse and Alfred Vail created the first practical version in 1837, and it took a few more years of refinements and public demonstrations before it became widely adopted. Overall, the process involved many inventors and incremental improvements, spanning about a decade from initial concepts to widespread use.

The V1 guided missile, also known as the "buzz bomb," was developed by Germany during World War II. The primary engineer behind its design was Hermann Oberth, a pioneering rocket scientist. The V1 was part of Germany's efforts to create advanced weaponry and was used extensively in the later stages of the war against Allied targets.

A plug cable casing is made from rubber primarily for its excellent insulation properties, which prevent electrical shocks and protect users from electrical hazards. Rubber is also flexible and durable, allowing the cable to withstand bending and movement without breaking. Additionally, rubber provides resistance to environmental factors such as moisture and temperature fluctuations, enhancing the longevity and safety of the cable.

Alfred Nobel is best known for inventing dynamite during the Industrial Revolution. Patented in 1867, dynamite was a safer and more manageable form of nitroglycerin, which facilitated construction, mining, and demolition activities. Nobel's invention significantly advanced engineering and industrial processes, though it also raised concerns due to its potential for destructive use. He later established the Nobel Prizes to honor those who contribute positively to humanity.

Cash, in the form of coins, was first introduced around 600 BC in Lydia, an ancient kingdom in what is now Turkey. These coins were made of electrum, a naturally occurring alloy of gold and silver. Paper money later emerged in China during the Tang Dynasty (618-907 AD), gaining prominence in the Song Dynasty (960-1279 AD). This evolution marked significant milestones in the development of cash as a medium of exchange.
