Study Notes
The Discovery of Coal
- Around 4,000 years ago, someone in northern China discovered an odd black rock that could burn, which was coal.
- This discovery was significant because keeping warm and getting food were major concerns in ancient times, and people relied on burning wood for heating and cooking.
Early Use of Coal
- Initially, only a few places with easy access to coal used it, including China and Britain.
- In Britain, coal was easily accessible, and people could even pick up lumps of coal on the beach, which they called "sea coal."
Roman Era and Decline
- During the Roman rule in the British isles, coal was used to heat water for public baths.
- The Romans brought British coal back to Rome with them, and traces of it can be found in Roman ruins in Italy.
- However, when the Western Roman Empire declined around 410 CE, coal usage declined, and it was nearly forgotten during the Dark Ages.
Revival of Coal in the 1200s
- Coal became popular again in the 1200s, especially in London, due to the growing population making it harder to find firewood.
- This marked the beginning of a significant event in human history.
The First Long-Distance Car Ride
- In 1888, Bertha Benz took the first 66-mile long-distance car ride with her two sons to visit her mother.
- Bertha took her husband Karl Benz's Benz Patent-Motorwagen, the first true automobile, without telling him.
- The trip was a success, and Bertha acted as her own mechanic, creating makeshift brake pads and cleaning fuel pipes.
The First Gas Station
- Bertha purchased a fluid called benzene from a local pharmacy to fill up the car, making it the world's first gas station.
Petroleum and Its History
- Petroleum is a liquid that comes from oil, used to power cars.
- Petroleum means "rock oil" and comes from the remains of once-living organisms, similar to coal.
- People have used petroleum for various purposes throughout history, but it wasn't widely used until the invention of the internal combustion engine.
The Internal Combustion Engine
- In 1863, Nikolaus Otto created the first successful internal combustion engine.
- The engine works by igniting fumes from a petroleum liquid, producing heat that moves pistons, similar to how gas-powered cars work today.
