By the late 19th century, scientists were frustrated. had written his famous equations for electromagnetism using quaternions, but they were so dense that almost no one could solve them. Classical Vector Algebra (Textbooks in Mathemat...

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.
