The wheel, invented around 3500 BC in Mesopotamia and potentially earlier in Carpathian mining regions, was a pivotal technological advance enabling the efficient transport of goods and people through carts and wagons, revolutionizing trade, agriculture, warfare, and craft industries by reducing friction and enabling mechanization. There is no known single inventor of the wheel. A curiosity is that the invention of the wheel may not have been for transportation at all, but for moving heavy ore. -
Technological advances in the steam engine, led to more efficient, higher-pressure engines and new applications beyond their initial use in mines. It included separate condenser for increased efficiency and high-pressure designs, which enabled the development of portable engines. The first practical steam engine was invented by Thomas Newcomen in England. A curiosity: the first practical steam-powered device, utilizing a partial vacuum to create mechanical motion for pumping water out of mines. -
Automotive technology has advanced significantly, driven by AI, connectivity, and a focus on sustainability and safety. Key advances include electric vehicles (EVs) powered by sustainable energy, autonomous driving with advanced AI and sensor systems. The first practical automobile, was invented by Karl Benz in Germany in 1885. A curiosity: is how, in just over a century, the vehicle has transformed from a simple mechanical machine into a sophisticated computer on wheels, integrating AI, advanc
