I'm not a studying physicist or anything else, but in my spare time I often sit and ponder the why and wherefore of things. Today's conundrum is: "Why don't massive or miniscule energy expenditures on the macroscale affect things on the atomic or subatomic scale." Everyday I use a knife or run across a sidewalk. Why don't these actions cause atomic or subatomic changes? When demolitions companies explode mountains or buildings, they don't worry about inadvertently triggering a nuclear blast. What forces allow atoms to bang about so stressfully without breaking the internal bonds?
