Clifford Algebras And Spinors -

Today, Clifford Algebras (often called ) are used far beyond particle physics. They are the go-to language for:

. To make this work, he couldn't use ordinary numbers; he needed matrices (the Gamma matrices). Clifford Algebras and Spinors

The "long story" of these tools is a transition from pure geometry to the realization that the universe is built out of objects that need to turn twice to stay the same. Today, Clifford Algebras (often called ) are used

The classic way to visualize this is the (or Dirac’s Belt): If you rotate an object 360 degrees, it looks the same. he couldn't use ordinary numbers
