About Energy

📜 Origins

James Joule discovered the relationship between heat and mechanical work in the 1840s, establishing the law of energy conservation.

⚡ Historical Highlight

Einstein's E=mc² revealed that a tiny amount of mass contains enormous energy. One gram of matter equals 90 trillion joules!

🎯 Fun Facts

  • A lightning bolt contains about 1 billion joules of energy - enough to power a 100W bulb for 3 months!
  • Eating a single M&M candy gives you about 3.4 calories, which equals 14,226 joules of energy.
  • The energy in gasoline is so dense that 1 gallon equals about 120 megajoules - equivalent to 33.7 kWh.

🏛️ Archaeological Discovery

Ancient Greeks used "water organs" (hydraulis) around 250 BCE, early understanding of converting water energy to sound.

🚀 Modern Applications

The Large Hadron Collider uses 14 teraelectronvolts (TeV) of energy to smash particles together, recreating conditions from the Big Bang.

😄 Measurement Humor

Why did the joule go to school? To get more potential energy! ⚡
