Superposition

Superposition can refer to:

• The superposition principle in physics, mathematics, and engineering, describes the overlapping of waves. Particular applications include :
  • Quantum superposition, in quantum physics
  • Superposition theorem, in electronics.
• The superposition calculus, used in logic for equational first-order reasoning
• The law of superposition in geology and archaeology which states that sedimentary layers are deposited in a time sequence, with the oldest on the bottom and the youngest on the top.
