All Weird Mathematical Operators

I see that mathematical operators vary by the field.

And also some operators are not even just symbols, but have a lot of theory backing them.

This is why I suggest the reformation in theory that all subjects should be explainable from scratch.
As they say, if you can't teach something to your grandma, you don't really know it.

Fluid Mechanics

  • \(\nabla\) (Nabla)
    • Vector Calculus: Gradient / Divergence / Curl
  • \(\Delta\) (Delta)
    • Vector Calculus: Laplace Operator
  • ◻ (Square)
    • Vector Calculus: D'Alembert Operator

Quantum Mechanics

  • \(\langle \: \rangle\) (Angle Brackets) - Expectation Values
  • Hermitian Operator

Mechanics

  • \(L\) - Lagrangian
  • \(H\) - Hamiltonian

Statistics

Advanced Math

Group Theory

Topology

General Relativity

  • \(\Lambda\) (Lambda)
  • \(\kappa\) (Kappa)
