Energy - the driving force of change
Lacking the concept of energy, ancient people live in a mysterious and
fearful world. They saw water coming from the unfriendly darkened sky
and accept flood as punishment. Long periods of terribly hot and dry sun
caused draught and hunger. They saw only change phenomena, but did
not realize changes, let alone their causes.
Changes cause winds, rains, storms, thunders, forest fires, earthquakes,
waves, growth, death, decay, ocean tides, freezing, melting, boiling,
Thanks to Thomson, Newton, Joule, Young, Faraday, and Einstein,
we now know the real driving force behind all changes is
energy. This energy concept explains all changes.
Potential energy converts to kinetic energy causing objects to fall and
Heat cooks food, changing natures of protein (steak) and starch (bread),
making food smell and taste great.
Chemical energy causes substances to burn.
Electric energy generates heat, kills and causes chemical reactions.
Energy causes radioactivity, and high-energy radiation causes injury,
illness and death.
Energy drives nuclear fission and fusion reactions.
Energy causes explosions, sending out heat and shock waves causing deaf,
blind, burn, and death.
Mismanagements of energy causes accidents.
Solar energy makes the weather including storms, draught, and flood.
Energy in radioactivity strips electrons from atoms and molecules.
