Muon decay is an excellent laboratory to explore the space-time structure of the weak interaction. The Standard Model makes precise predictions for the Michel parameters that characterize the energy and angle dependence of the positrons that are emitted in polarized muon decay. TWIST is searching for new physics via measurements of the Michel parameters $\rho$, $\delta$, and $P_{\mu}\xi$ to a few parts in 10$^4$. Initial TWIST physics results, measurements of $\rho$ and $\delta$ to ~0.001, are now available. The TWIST experiment, the initial physics results and their implications, and future plans will be discussed.
