Einstein's purely algebraic physics and "my entire castle in the air"

[QUOTE="robwilson, post: 6434718, member: 685414"] It is always worth listening to Einstein. Even if he predicts the demise of [the whole of] modern physics. All of modern physics is based on geometry, and Einstein is suggesting an algebraic approach instead. The basic idea is that instead of using SU(2) to describe spin, you just use the quaternion group Q_8. So instead of having a continuous magnetic field as in the classical theory, you just have a bunch of discrete spins. A great deal can be done with this approach, but I don't know that anyone has got as far as describing black holes or gravitational waves. First they would need to develop an algebraic quantum theory of gravity. [/QUOTE]
