The (measuring how much vectors go in the same direction).

In modern high-level physics (like General Relativity or Quantum Mechanics), we’ve actually circled back to more complex structures like Tensors and Spinors that look a lot more like those "monstrous" quaternions than Hamilton ever could have dreamed.

They split quaternion multiplication into two distinct operations: The (measuring how much vectors go in the same direction)
