They split quaternion multiplication into two distinct operations:

The history of isn’t just a dry sequence of formulas; it’s the story of a hundred-year "math war" over how to describe the physical world. 1. The Shadow of Hamilton (1840s) 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. But Heaviside didn't care about "mathematical elegance

But Heaviside didn't care about "mathematical elegance." He was a telegraph engineer who wanted tools that worked. He famously said, "Vectors are a great help to a man who has any physics in him." He used this "new" vector algebra to condense Maxwell’s 20 original equations down to the 4 we use today. 4. Victory and the Modern Textbook Victory and the Modern Textbook
