Scientific Law

The idea
A scientific law is a concise, often mathematical statement describing a pattern in nature without explaining why it occurs.
In practice
The law of conservation of matter states mass is conserved during chemical change; a theory of bonding explains why that holds.
Where people slip
A law is not an upgraded theory — laws describe a pattern, theories explain a mechanism, both equally well-established.
