Takeaways

• 😀 The wheel is one of humanity's oldest inventions, originating in the Neolithic age for constructing megalithic structures.
• 😀 The first actual wheel used for transportation emerged in Mesopotamia, approximately 300 years after the invention of the potter's wheel.
• 😀 Early methods of moving heavy objects included rolling logs and using sledges, which were later combined to form the first wheel designs.
• 😀 The evolution of the wheel included significant improvements such as the fixed axle, allowing wheels to turn independently, reducing friction.
• 😀 Ancient Egyptians innovated the wheel with the introduction of spokes, greatly reducing weight and improving efficiency in transportation.
• 😀 The introduction of iron rims by the Celts improved the durability of wooden wheels, addressing wear and tear issues.
• 😀 Comfort in wheel design was addressed with the invention of pneumatic tires, patented by Robert William Thompson in 1847.
• 😀 The first successful pneumatic tire for bicycles was developed by John Boyd Dunlop in 1888, paving the way for modern tires.
• 😀 Wire wheels gained popularity for cars due to their lightweight and strong design, but were eventually replaced by stamped steel wheels for cost efficiency.
