Lie Group Quotes (2 quotes)
Keplers principal goal was to explain the relationship between the existence of five planets (and their motions) and the five regular solids. It is customary to sneer at Kepler for this. It is instructive to compare this with the current attempts to explain the zoology of elementary particles in terms of irreducible representations of Lie groups.
No other theory known to science [other than superstring theory] uses such powerful mathematics at such a fundamental level. because any unified field theory first must absorb the Riemannian geometry of Einsteins theory and the Lie groups coming from quantum field theory The new mathematics, which is responsible for the merger of these two theories, is topology, and it is responsible for accomplishing the seemingly impossible task of abolishing the infinities of a quantum theory of gravity.
